[0033] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] In this context, air conditioner 100 refers to an air conditioning unit, which includes an indoor unit and an outdoor unit. Air conditioner 100 is a unit used to provide temperature-controlled air to a space (generally enclosed). The function of air conditioner 100 is to regulate parameters such as temperature, humidity, cleanliness, and airflow velocity of the air in a room (or enclosed space, area) by generating cool or hot air to meet the requirements of human comfort or process control. In this embodiment, air conditioner 100 may refer to the outdoor unit.

[0035] Reference Figure 1 , Figure 2 , Figures 6-13 As shown, the air conditioner 100 according to an embodiment of the present utility model may include: a housing 1, a valve island assembly 5, and functional components 30.

[0036] Specifically, the valve island assembly 5 is housed within the housing 1. The housing 1 protects the valve island assembly 5 and the functional components 30 from exposure and damage, thus extending the service life of the air conditioner 100. The valve island assembly 5 contains a fluid channel, through which the functional components 30 can communicate. The valve island assembly 5 can replace the original piping, and the functional components 30 connect with other structures via the valve island assembly 5, forming a complete flow path. This reduces pipe length and minimizes pressure drops caused by increased pipe resistance due to longer pipe length. Furthermore, it reduces the number of weld points between pipes, lowering the risk of weld point leaks. This improves assembly efficiency, production efficiency, and reliability.

[0037] Furthermore, the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, allowing the valve island assembly 5 to utilize the space of the functional component 30 in the vertical direction, and / or, the projections of the valve island assembly 5 and the functional component 30 on the vertical plane in the up-down direction at least partially overlap, allowing the valve island assembly 5 to utilize the space on one side of the functional component 30 in the circumferential direction. This helps to reduce the occupation of other spaces, making the structure compact and the space utilization rate inside the air conditioner 100 high, saving space and thus reducing the space occupied by the air conditioner 100.

[0038] According to an embodiment of the present invention, the air conditioner 100 uses a functional component 30 to communicate with the fluid channel of the valve island assembly 5, allowing the valve island assembly 5 to replace the original piping. This reduces pipe length, pipe resistance, and pressure loss, and also reduces the number of weld points between pipes, lowering the risk of weld point leakage and improving production efficiency and reliability. Furthermore, the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, and / or the projections of the valve island assembly 5 and the functional component 30 on the vertical plane in the vertical direction at least partially overlap. This reduces the space occupied by other components, resulting in a compact structure, high space utilization within the air conditioner 100, and space savings, thereby reducing the space occupied by the air conditioner 100.

[0039] In some embodiments of this utility model, the valve island assembly 5 includes a plurality of (two or more) valve island bodies. At least one of the plurality of valve island bodies at least partially overlaps with the projection of the functional component 30 on the horizontal plane, so that the plurality of valve island bodies can utilize the space of the functional component 30 in the height direction. At least one of the plurality of valve island bodies at least partially overlaps with the projection of the functional component 30 on the vertical plane in the up-down direction, so that the plurality of valve island bodies can utilize the space on one side of the functional component 30 in the circumferential direction, reducing the occupation of other spaces, making the structure compact, the space utilization rate inside the air conditioner 100 is high, and space can be saved, thereby reducing the space occupied by the air conditioner 100.

[0040] According to some embodiments of this utility model, when the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, the area of ​​the overlapping region of the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane is greater than or equal to 150 mm². This allows the valve island assembly 5 to occupy as much space as possible in the height direction of the functional component 30, reducing the occupation of other spaces, resulting in a compact structure, high space utilization inside the air conditioner 100, and space saving, thereby reducing the space occupied by the air conditioner 100. For example, in some specific embodiments, when the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, the area of ​​the overlapping region of the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane can be 150 mm², 160 mm², 180 mm², 190 mm², 200 mm², etc.

[0041] In some embodiments of this utility model, when the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, the maximum value of the minimum distance from all points of the portion of the valve island assembly 5 on the horizontal plane that are outside the projection of the functional component 30 on the horizontal plane to the functional component 30 is less than or equal to 300mm. This allows the valve island assembly 5 to occupy as little space as possible in the height direction of the functional component 30, thereby reducing the occupation of other spaces, making the structure compact, and achieving high space utilization inside the air conditioner 100, thus saving space and reducing the space occupied by the air conditioner 100. For example, in some specific embodiments, when the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, the maximum value of the minimum distance from all points of the portion of the valve island assembly 5 on the horizontal plane that are outside the projection of the functional component 30 on the horizontal plane to the functional component 30 can be 300mm, 280mm, 260mm, 240mm, 220mm, 200mm, etc.

[0042] It is understandable that the projection of valve island assembly 5 on the horizontal plane is the first projection, the projection of functional component 30 on the horizontal plane is the second projection, the part of the first projection outside the second projection is the first external projection, and the maximum value of the minimum distance (this distance does not cross the functional component 30) from all points of the first external projection to the outer peripheral wall of the functional component 30 is less than or equal to 300mm.

[0043] In some embodiments, when the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, the portion of the projection of the valve island assembly 5 on the horizontal plane that is outside the projection of the functional component 30 on the horizontal plane has a length along the length of the air conditioner 100 that is less than or equal to 265 mm. This allows the valve island assembly 5 to occupy as little space as possible in the height direction of the functional component 30 along the length of the air conditioner 100, thereby reducing the occupation of other spaces, resulting in a compact structure, high space utilization inside the air conditioner 100, and space saving, thus reducing the space occupied by the air conditioner 100. For example, in some specific embodiments, when the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, the portion of the projection of the valve island assembly 5 on the horizontal plane that is outside the projection of the functional component 30 on the horizontal plane along the length of the air conditioner 100 can be 265 mm, 260 mm, 250 mm, 240 mm, 230 mm, etc.

This allows the valve island assembly 5 to occupy as little space as possible in the height direction of the functional component 30 along the width direction of the air conditioner 100, thereby reducing the occupation of other spaces, resulting in a compact structure, high space utilization inside the air conditioner 100, and space saving, thus reducing the space occupied by the air conditioner 100. For example, in some specific embodiments, when the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially overlap, the dimension of the portion of the projection of the valve island assembly 5 on the horizontal plane that is outside the projection of the functional component 30 on the horizontal plane along the width direction of the air conditioner 100 can be 280 mm, 270 mm, 260 mm, 250 mm, 240 mm, etc.

[0046] It is understandable that the projection of the valve island assembly 5 on the horizontal plane is the first projection, the projection of the functional component 30 on the horizontal plane is the second projection, the part of the first projection outside the second projection is the first external projection, and the dimension of the first external projection along the width direction of the air conditioner 100 is less than or equal to 280mm.

[0048] It is understandable that the projection of valve island assembly 5 on the horizontal plane is the first projection, the projection of functional component 30 on the horizontal plane is the second projection, and the portion of the first projection outside the second projection is the first external projection. Along the length of air conditioner 100, the size of the first external projection is B1, the size of the air conditioner is C1, and it satisfies: .

[0049] In some embodiments, along the width direction of the air conditioner 100, the dimension of the portion of the valve island assembly 5 projected onto the horizontal plane that is outside the projection of the functional component 30 onto the horizontal plane is B2, the dimension of the air conditioner is C2, and the following conditions are met: This allows the valve island assembly 5 to occupy as little space as possible in the height direction of the functional component 30 along the width direction of the air conditioner 100, thereby reducing the occupation of other spaces, making the structure compact, and achieving high space utilization inside the air conditioner 100, thus saving space and reducing the space occupied by the air conditioner 100.

[0051] According to some embodiments of this utility model, when the projections of the valve island assembly 5 and the functional component 30 in the vertical plane along the up-down direction at least partially overlap, the area of ​​the overlapping region of the projections of the valve island assembly 5 and the functional component 30 in the vertical plane along the up-down direction is greater than or equal to 150 mm². This allows the valve island assembly 5 to occupy as much space as possible in the circumferential direction of the functional component 30, reducing the occupation of other spaces, resulting in a compact structure, high space utilization inside the air conditioner 100, and space saving, thereby reducing the space occupied by the air conditioner 100. For example, in some specific embodiments, when the projections of the valve island assembly 5 and the functional component 30 in the vertical plane along the up-down direction at least partially overlap, the area of ​​the overlapping region of the projections of the valve island assembly 5 and the functional component 30 in the vertical plane along the up-down direction can be 150 mm², 200 mm², 250 mm², 300 mm², 350 mm², etc.

This allows the valve island assembly 5 to occupy as little space as possible in the circumferential direction of the functional component 30, thereby reducing the occupation of other spaces, making the structure compact, and achieving high space utilization inside the air conditioner 100, thus saving space and reducing the space occupied by the air conditioner 100.

[0054] In some embodiments, when the projections of the valve island assembly 5 and the functional component 30 onto the vertical plane in the vertical direction at least partially overlap, the portion of the projection of the valve island assembly 5 onto the vertical plane that is outside the projection of the functional component 30 onto the vertical plane in the vertical direction has a dimension along the height direction of the air conditioner 100 that is less than or equal to 400 mm. This allows the valve island assembly 5 to occupy as little space as possible in the circumferential direction of the functional component 30 along the height direction of the air conditioner 100, thereby reducing the occupation of other spaces, resulting in a compact structure, high space utilization inside the air conditioner 100, and space saving, thus reducing the space occupied by the air conditioner 100. For example, in some specific embodiments, when the projections of the valve island assembly 5 and the functional component 30 onto the vertical plane in the vertical direction at least partially overlap, the dimension of the portion of the projection of the valve island assembly 5 onto the vertical plane that is outside the projection of the functional component 30 onto the vertical plane in the vertical direction along the height direction of the air conditioner 100 can be 400 mm, 350 mm, 300 mm, 250 mm, 200 mm, etc.

[0055] In some embodiments, when the projections of the valve island assembly 5 and the functional component 30 onto the vertical plane in the vertical direction at least partially overlap, the portion of the projection of the valve island assembly 5 onto the vertical plane that is outside the projection of the functional component 30 onto the vertical plane in the vertical direction has a dimension along the width direction of the air conditioner 100 that is less than or equal to 300 mm. This allows the valve island assembly 5 to occupy as little space as possible in the circumferential direction of the functional component 30 along the width direction of the air conditioner 100, thereby reducing the occupation of other spaces, resulting in a compact structure, high space utilization inside the air conditioner 100, and space saving, thus reducing the space occupied by the air conditioner 100. For example, in some specific embodiments, when the projections of the valve island assembly 5 and the functional component 30 onto the vertical plane in the vertical direction at least partially overlap, the dimension of the portion of the projection of the valve island assembly 5 onto the vertical plane that is outside the projection of the functional component 30 onto the vertical plane in the vertical direction along the width direction of the air conditioner 100 can be 300 mm, 250 mm, 200 mm, 150 mm, 100 mm, etc.

[0056] It is understandable that the projection of the valve island assembly 5 along the vertical direction on the vertical plane is the third projection, the projection of the functional component 30 along the vertical direction on the vertical plane is the fourth projection, the part of the third projection outside the fourth projection is the second external projection, the dimension of the second external projection along the height direction of the air conditioner 100 is less than or equal to 400mm, and / or, the dimension of the second external projection along the width direction of the air conditioner 100 is less than or equal to 300mm.

[0057] In some embodiments, along the height direction of the air conditioner 100, the dimension of the portion of the valve island assembly 5 located outside the projection of the functional component 30 along the vertical direction in the vertical plane along the vertical direction is B3, the dimension of the air conditioner is C3, and the following conditions are met: This allows the valve island assembly 5 to occupy as little space as possible in the circumferential direction of the functional component 30 along the height direction of the air conditioner 100, thereby reducing the occupation of other spaces, making the structure compact, and achieving high space utilization inside the air conditioner 100, thus saving space and reducing the space occupied by the air conditioner 100.

[0058] It is understandable that the projection of valve island assembly 5 along the vertical direction on the vertical plane is the third projection, the projection of functional component 30 along the vertical direction on the vertical plane is the fourth projection, and the portion of the third projection outside the fourth projection is the second external projection. Along the height direction of air conditioner 100, the size of the second external projection is B3, the size of the air conditioner is C3, and it satisfies: .

[0059] In some embodiments, along the width direction of the air conditioner 100, the dimension of the portion of the valve island assembly 5 projected vertically in the up-down direction onto the vertical plane that is outside the projection of the functional component 30 projected vertically in the up-down direction onto the vertical plane is B4, the dimension of the air conditioner is C4, and the following conditions are met: This allows the valve island assembly 5 to occupy as little space as possible in the circumferential direction of the functional component 30 along the width direction of the air conditioner 100, thereby reducing the occupation of other spaces, making the structure compact, and achieving high space utilization inside the air conditioner 100, thus saving space and reducing the space occupied by the air conditioner 100.

[0060] It is understandable that the projection of valve island assembly 5 along the vertical direction on the vertical plane is the third projection, the projection of functional component 30 along the vertical direction on the vertical plane is the fourth projection, and the portion of the third projection outside the fourth projection is the second external projection. Along the width direction of air conditioner 100, the size of the second external projection is B4, the size of air conditioner is C4, and it satisfies: .

[0061] According to some embodiments of this utility model, such as Figure 1 , Figure 6 , Figure 7 , Figures 10-13 As shown, the functional component 30 is located below the valve island assembly 5. The valve island assembly 5 can utilize the space above the functional component 30, which helps to reduce the occupation of other spaces, making the structure compact and the space utilization rate inside the air conditioner 100 high, thus saving space and reducing the space occupied by the air conditioner 100.

[0062] In addition, such as Figure 12 As shown, the distance between the lower end of the valve island assembly 5 and the upper end of the functional component 30 is greater than or equal to 60mm, that is, the distance between the lower end of the valve island assembly 5 and the upper end of the functional component 30 is D and satisfies D≥60mm. Within the above-mentioned size range, the structure between the valve island assembly 5 and the functional component 30 can be compact, which facilitates the reduction of the space occupied in the height direction, thereby reducing the space occupied in the height direction of the air conditioner 100. At the same time, it can avoid interference between the valve island assembly 5 and the functional component 30, and meet the required assembly requirements. For example, in some specific embodiments, the minimum distance between the lower end of the valve island assembly 5 and the upper end of the functional component 30 can be 60mm, 65mm, 70mm, 75mm, 80mm, etc.

[0063] In some embodiments, the centerline of the functional component 30 does not coincide with the centerline of the valve island assembly 5, which allows for more flexible placement of the valve island assembly 5 and enables it to be set according to actual requirements, thereby meeting different requirements. Furthermore, the projections of the valve island assembly 5 and the functional component 30 on the horizontal plane at least partially coincide, and / or the projections of the valve island assembly 5 and the functional component 30 on the vertical plane along the vertical direction at least partially coincide, which helps to reduce the occupation of other spaces, making the structure compact and the space utilization rate inside the air conditioner 100 high, thus saving space and reducing the space occupied by the air conditioner 100.

[0064] It is understandable that the "center line of valve island assembly 5" here is a straight line that passes through the center of the circumcircle of the projection of valve island assembly 5 on the horizontal plane and extends in the vertical direction. The "center line of functional component 30" here needs to be determined according to the specific structure of functional component 30. When functional component 30 is a tank containing refrigerant, the center line of functional component 30 is a straight line that passes through the center of the circumcircle of the cross-section of functional component 30.

[0065] For example, when the projections of the centerline of the functional component 30 and the centerline of the valve island assembly 5 onto the horizontal plane do not coincide, the point projected by the centerline of the valve island assembly 5 onto the horizontal plane does not coincide with the point projected by the centerline of the functional component 30 onto the horizontal plane, allowing for more flexible placement of the valve island assembly 5; when the projections of the centerline of the functional component 30 and the centerline of the valve island assembly 5 onto the vertical plane do not coincide, the straight line projected by the centerline of the valve island assembly 5 onto the vertical plane does not coincide with the straight line projected by the centerline of the functional component 30 onto the vertical plane, allowing for more flexible placement of the valve island assembly 5.

[0066] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figures 5-13 As shown, functional component 30 includes a refrigerant tank, which is connected to other structures via valve island assembly 5 to form a complete flow path. This reduces pipe length, mitigating pressure drops caused by increased pipe resistance due to pipe length issues. It also reduces the number of weld points between pipes, lowering the risk of weld point leaks and improving assembly efficiency, production efficiency, and reliability. Simultaneously, valve island assembly 5 utilizes the space of the refrigerant tank in the vertical and / or circumferential directions, reducing the space occupied by other components, resulting in a compact structure and high space utilization within the air conditioner 100, saving space and reducing the space occupied by the air conditioner 100. For example, the refrigerant tank can be a compressor 2, a gas-liquid separator 3, an oil-gas separator 42, and a liquid receiver tank.

[0067] In some embodiments, such as Figure 1 , Figure 2 and Figure 8 As shown, the housing 1 is located on the outside of the air conditioner 100, thus providing support for the air conditioner 100. An installation space is formed inside the housing 1, where various structures required for the operation of the air conditioner 100 can be installed. The housing 1 can protect these structures and also provide installation points for the various structures inside the air conditioner 100, ensuring installation reliability. A partition 12 can be installed inside the air conditioner 100. The partition 12 can be connected to the housing 1 by means of connectors or welding. The connectors can be bolts, etc. The structure is simple, the installation is convenient, and the installation cost is low.

[0068] like Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 12 and Figure 13As shown, a compressor assembly can be installed within the housing 1. The compressor assembly includes a compressor 2, a gas-liquid separator 3, and a flow path integration module 4. The flow path integration module 4 includes at least one of a reversing valve 43, an expansion valve 44, a plate heat exchanger 41, a gas-liquid separator 3, an oil-gas separator 42, a solenoid valve 45, a high-pressure valve 46, and a low-pressure valve 47. The flow path integration module 4 can be connected to the compressor 2 and the gas-liquid separator 3 to form a refrigerant circuit, ensuring the reliable operation of the air conditioner 100. Furthermore, the gas-liquid separator 3 is connected to the housing 1, the valve island assembly 5 is mounted and supported on the gas-liquid separator 3, and the flow path integration module 4 is connected to the valve island assembly 5 and communicates with the compressor 2 and the gas-liquid separator 3 to form a refrigerant circuit. For example, the reversing valve 43 can be a four-way valve.

[0069] Therefore, by connecting the flow path integration module 4 to the compressor 2 and the gas-liquid separator 3 through the valve island assembly 5 to form a refrigerant circuit, the sound radiation path generated by the vibration of the compressor 2 and other components can be blocked through the valve island assembly 5, thereby reducing the noise generated by the air conditioner 100 during operation, improving the user experience, increasing integration, reducing space occupation, reducing production costs, improving lightweighting, reducing leakage risk, and improving reliability.

[0070] In some embodiments, the functional component 30 may include a compressor assembly, that is, the functional component 30 may include at least one of a compressor 2, a gas-liquid separator 3 and a plurality of flow path integration modules 4. By having the valve island assembly 5 at least partially overlap with the projection of the functional component 30 on the horizontal plane and / or the valve island assembly 5 at least partially overlap with the projection of the functional component 30 on the vertical plane along the vertical direction of the horizontal plane, the structure can be compact, reducing the occupation of other spaces, and the space utilization rate inside the air conditioner 100 is high, which can save space and thus reduce the space occupied by the air conditioner 100.

[0071] In some embodiments, the valve island assembly 5 can be mounted and supported on the gas-liquid separator 3 by means of connectors or welding, and the gas-liquid separator 3 can be connected to the housing 1 by means of connectors or welding. The compressor 2 is spaced apart from the gas-liquid separator 3 and can also be connected to the housing 1 by means of connectors or welding, so that the valve island assembly 5 can be fixedly installed in the housing 1 only by the gas-liquid separator 3. The flow path integration module 4 can be connected to the valve island assembly 5, and the flow path integration module 4 can be connected to the compressor 2 and the gas-liquid separator 3 to form a refrigerant circuit, so that the valve island assembly 5 can be spaced apart from the compressor 2 and other structures to isolate the vibration generated by the compressor 2 and other structures during operation, thereby reducing the noise generated by the air conditioner 100 during operation and improving the user experience.

[0072] In addition, the flow path integration module 4 is connected to the valve island component 5, which shortens the length of the refrigerant pipeline and reduces the space occupied by multiple refrigerant pipelines, thereby improving the integration and weight reduction, and reducing the installation cost. At the same time, it can reduce the number of connection points of multiple refrigerant pipelines, thereby reducing the risk of leakage of refrigerant and other media and improving the reliability of the air conditioner 100.

[0073] It is understood that air conditioner 100 is an air conditioning unit, which has structures such as indoor unit and outdoor unit. Air conditioner 100 is a unit used to provide air temperature control for a space (generally enclosed). The function of air conditioner 100 is to regulate parameters such as temperature, humidity, cleanliness, and airflow of the air in a room (or enclosed space, area) by producing cool or hot air to meet the requirements of human comfort or process. In this embodiment, air conditioner 100 may refer to outdoor unit.

[0074] According to some embodiments of this utility model, such as Figure 1 , Figure 2 , Figures 8-13 As shown, when the functional component 30 includes a gas-liquid separator 3, the gas-liquid separator 3 is fixed to the housing 1, which can limit the movement of the gas-liquid separator 3 and ensure that the gas-liquid separator 3 is reliably fixed within the housing 1. The gas-liquid separator 3 is connected to the fluid channel, allowing it to connect with other structures through the valve island assembly 5 to form a complete flow path. This reduces the length of the pipeline and the number of weld points between pipelines, lowering the risk of weld point leakage. This is beneficial for improving the assembly efficiency of the final assembly, and facilitates improved production efficiency and reliability.

[0075] In addition, such as Figure 1 , Figure 2 , Figures 8-13 As shown, the valve island assembly 5 is connected to the gas-liquid separator 3, which facilitates communication between the gas-liquid separator 3 and the fluid channel, reduces the communication path, and allows the gas-liquid separator 3 to limit the valve island assembly 5, ensuring that the valve island assembly 5 is reliably fixed in the housing 1.

[0076] In some embodiments of this utility model, such as Figures 1-3 , Figure 5 , Figure 6 , Figure 12 and Figure 13As shown, the valve island assembly 5 includes a valve island body 51 and a valve island support 52. The valve island support 52 is fixedly connected to the gas-liquid separator 3 and the housing 1, so that the valve island support 52 can be reliably fixed on the housing 1 to prevent shaking. The end of the valve island body 51 away from the gas-liquid separator 3 is connected to the valve island support 52, so that the valve island body 51 can be reliably fixed under the joint support of the valve island support 52 and the gas-liquid separator 3 to prevent shaking. This ensures that the components connected to the valve island assembly 5 are reliably connected and prevents loosening.

[0077] According to some embodiments of this utility model, the valve island support 52 and the gas-liquid separator 3 are connected by welding to ensure that the valve island support 52 and the gas-liquid separator 3 are reliably connected, to prevent the valve island support 52 from becoming loose, and to facilitate processing and manufacturing, which helps to reduce production costs.

[0078] Alternatively, the valve island bracket 52 can be detachably connected to the gas-liquid separator 3, ensuring a reliable connection between the two while also allowing for separation for easy maintenance or replacement. For example, the valve island bracket 52 and the gas-liquid separator 3 can be connected using screws or rivets.

[0079] In some embodiments, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figures 11-13 As shown, a compressor assembly can be installed inside the housing 1. The compressor assembly includes a flow path integration module 4, a valve island bracket 52 is mounted and supported on the gas-liquid separator 3, and the valve island body 51 is supported above the valve island bracket 52. The flow path integration module 4 is connected to the valve island body 51.

[0080] Specifically, such as Figures 1-2 and Figure 8 As shown, the valve island assembly 5 is mounted and supported on the gas-liquid separator 3. The valve island assembly 5 is provided with a valve island body 51 and a valve island bracket 52. The valve island bracket 52 can be installed on the gas-liquid separator 3 by welding or connecting parts, and the valve island body 51 can be installed and supported on the top of the valve island bracket 52. This allows the valve island body 51 to be mounted and supported on the gas-liquid separator 3 through the valve island bracket 52, which is convenient for installation. It also ensures that the valve island body 51 is only connected to the gas-liquid separator 3, thereby isolating the vibration generated by the operation of other structures, reducing the noise generated by the air conditioner 100 during operation, and improving the user experience.

[0081] Furthermore, the flow path integration module 4 is connected to the valve island body 51, which can shorten the length of the refrigerant pipeline to improve integration, reduce the space occupied by multiple refrigerant pipelines, improve lightweighting, and reduce production costs. In actual installation, the valve island bracket 52 can be made of carbon steel, stainless steel, aluminum alloy, etc., which can ensure the structural strength of the valve island bracket 52 and improve the installation reliability of the valve island body 51.

[0082] The valve island body 51 can be composed of multiple solenoid valves 45, which can share the same air intake source, but each has an independent output. Each solenoid valve 45 can open upon receiving an electrical control signal and send a pneumatic signal to drive other components. The valve island body 51 can control multiple valves and their signal processing, thereby achieving automatic fluid regulation and diversion. By controlling the opening and closing of the valves, the valve island body 51 can regulate fluid flow and pressure, thus improving the automation level of the air conditioner 100.

[0083] In some embodiments, at least a portion of the valve island support 52 is spaced apart from the valve island body 51 and together defines an installation area 53. The flow path integration module 4 includes a plate heat exchanger 41, which is connected to the valve island body 51 and located within the installation area 53.

[0084] Specifically, the flow path integration module 4 is equipped with a plate heat exchanger 41. The plate heat exchanger 41 is a high-efficiency heat exchanger made of stacked metal plates with a certain corrugated shape. Thin rectangular channels are formed between the various plates, and heat exchange occurs through the plates. Figures 1-2 As shown, the plate heat exchanger 41 can be connected to the valve island body 51, so that the plate heat exchanger 41 can also be installed only on the valve island body 51, thereby isolating vibration.

[0085] Furthermore, the valve island body 51 is mounted on the gas-liquid separator 3 via the valve island support 52, and at least a portion of the valve island support 52 is spaced apart from the valve island body 51, that is, the valve island body 51 is only partially connected to the valve island support 52 to connect to the gas-liquid separator 3, and another portion of the valve island body 51 can be spaced apart from the valve island support 52, so that the other portion of the valve island body 51 and the valve island support 52 can jointly define the installation area 53, and the plate heat exchanger 41 can be disposed within the installation area 53.

[0086] Thus, the valve island bracket 52 can support both the valve island body 51 and the plate heat exchanger 41, ensuring the reliable installation of both. It also allows the valve island body 51 and the plate heat exchanger 41 to be connected to the gas-liquid separator 3 only through the valve island bracket 52, thus isolating vibration, ensuring the reliability of the air conditioner 100, and improving the user experience. Furthermore, directly connecting the plate heat exchanger 41 to the valve island body 51 reduces the need for refrigerant piping, lowering installation costs, and increasing integration for weight reduction.

[0087] In some embodiments, the valve island support 52 includes a first sub-plate 521, a connecting plate 522 and a second sub-plate 523. The connecting plate 522 is bent and connected between the first sub-plate 521 and the second sub-plate 523. The first sub-plate 521 is connected to the gas-liquid separator 3. The connecting plate 522 and the second sub-plate 523 together with the valve island body 51 define the installation area 53.

[0088] Specifically, the valve island body 51 can be connected to the gas-liquid separator 3 via the valve island support 52, and as shown in the figure. Figures 2-3 As shown, the valve island support 52 is provided with a first sub-plate 521, a connecting plate 522, and a second sub-plate 523. The first sub-plate 521 and the second sub-plate 523 are spaced apart, and one end of the connecting plate 522 is bent and connected to the first sub-plate 521, while the other end of the connecting plate 522 is bent and connected to the second sub-plate 523. That is, the connecting plate 522 is bent and connected between the first sub-plate 521 and the second sub-plate 523. The connecting plate 522 is connected to the side of the first sub-plate 521 and the second sub-plate 523 that is close to each other. The end of the first sub-plate 521 away from the connecting plate 522 can extend to connect with the gas-liquid separator 3, and the end of the second sub-plate 523 away from the connecting plate 522 can extend in a direction away from the gas-liquid separator 3, so that the connecting plate 522, the second sub-plate 523, and the valve island body 51 can jointly define the installation area 53.

[0089] Thus, the gas-liquid separator 3 can support the valve island bracket 52 to improve the installation reliability of the valve island body 51. The connecting plate 522, the second sub-plate 523 and the valve island body 51 define an installation area 53, within which the plate heat exchanger 41 can be installed. The second sub-plate 523 can support the plate heat exchanger 41, thereby improving the installation reliability of the plate heat exchanger 41, increasing space utilization, improving integration and weight reduction, and reducing the installation cost by minimizing the refrigerant piping.

[0090] In some embodiments, the connecting plate 522 extends vertically, and the first sub-plate 521 and the second sub-plate 523 both extend horizontally and are connected to the upper and lower ends of the connecting plate 522. The first sub-plate 521 and the second sub-plate 523 are located on different sides of the connecting plate 522, wherein the first sub-plate 521 is supported on the top surface of the gas-liquid separator 3, and the plate heat exchanger 41 is supported above the second sub-plate 523.

[0091] Specifically, the connecting plate 522 is bent and connected between the first sub-plate 521 and the second sub-plate 523, and as shown in the figure. Figure 3 and Figures 5-6 As shown, the first sub-plate 521 is configured to extend horizontally, the second sub-plate 523 is also configured to extend horizontally, and the connecting plate 522 is configured to extend vertically, so that the first sub-plate 521 and the second sub-plate 523 can be vertically connected to the upper and lower ends of the connecting plate 522 respectively. The first sub-plate 521 is connected to the top surface of the gas-liquid separator 3, and the top surface of the gas-liquid separator 3 is also configured to extend horizontally, so that the first sub-plate 521 can be closely connected to the top surface of the gas-liquid separator 3, thereby improving the support reliability of the gas-liquid separator 3 on the first sub-plate 521, so as to ensure the installation reliability of the valve island body 51.

[0092] Furthermore, the gas-liquid separator 3 can be configured as a columnar structure, that is, the side wall of the gas-liquid separator 3 can be set perpendicular to the top surface, so that when the first sub-plate 521 is connected to the top surface of the gas-liquid separator 3, the side wall of the gas-liquid separator 3 can support the connecting plate 522, thereby dispersing the force on the valve island support 52 and improving the reliability of the valve island support 52.

[0093] In addition, the second sub-plate 523 also extends horizontally, and the first sub-plate 521 and the second sub-plate 523 are located on different sides of the connecting plate 522, that is, the second sub-plate 523 extends away from the gas-liquid separator 3, so that the second sub-plate 523, the connecting plate 522 and the valve island body 51 can define an installation area 53, and the bottom of the plate heat exchanger 41 can contact the second sub-plate 523 to ensure the reliability of the support for the plate heat exchanger 41, and reduce the force on the bottom of the valve island body 51, thus ensuring the installation reliability of the valve island body 51.

[0094] In some embodiments, the second subplate 523 has a first limiting flange 524 on the side edge away from the connecting plate 522. The first limiting flange 524 is bent upward and distributed opposite to the connecting plate 522. The first limiting flange 524 is used to limit the engagement with the plate heat exchanger 41.

[0095] Specifically, one side of the second sub-plate 523 is connected to the connecting plate 522, and the other side extends away from the connecting plate 522, and as shown... Figure 3As shown, a first limiting flange 524 is formed on the side of the second sub-plate 523 away from the connecting plate 522. The first limiting flange 524 extends upward on the side of the second sub-plate 523 away from the connecting plate 522. The first limiting flange 524 and the connecting plate 522 are distributed opposite to each other, so that a limiting space can be defined between the first limiting flange 524 and the connecting plate 522. The limiting space is connected to the installation area 53. The plate heat exchanger 41 can extend from the installation area 53 into the limiting space, so that the first limiting flange 524 and the connecting plate 522 can limit the plate heat exchanger 41, thereby improving the installation accuracy. It can also limit the plate heat exchanger 41 in the horizontal direction, thereby improving the reliability of the connection between the plate heat exchanger 41 and the valve island body 51.

[0096] In some embodiments, the gas-liquid separator 3 is provided with at least one first positioning part 31, which is positioned and cooperates with the valve island support 52, or the first positioning part 31 is positioned and cooperates with the valve island support 52 and the valve island body 51 in sequence.

[0097] Specifically, the gas-liquid separator 3 may be provided with at least one first positioning part 31, that is, the gas-liquid separator 3 may be provided with one, two or three first positioning parts 31, the first positioning part 31 may be a positioning column, etc., and the first positioning part 31 may also be the inlet column or outlet column of the gas-liquid separator 3, etc., thereby improving the integration of the structure, reducing the setting of other structures, and reducing the setting cost.

[0098] Furthermore, the first positioning part 31 can be configured to position and cooperate with the valve island bracket 52, or the first positioning part 31 can also be configured to position and cooperate with the valve island bracket 52 and the valve island body 51 in sequence. That is, in actual installation, the valve island bracket 52 can be installed on the gas-liquid separator 3 first, such as... Figure 2 and Figure 5 As shown, the valve island bracket 52 is provided with a first positioning mating part 525. The first positioning mating part 525 can be configured as a positioning hole, etc., so that the first positioning mating part 525 of the valve island bracket 52 can be positioned and mated with the first positioning part 31. After the valve island bracket 52 is installed, the valve island body 51 is then installed on the valve island bracket 52 to ensure installation accuracy.

[0099] In addition, the valve island bracket 52 and the valve island body 51 can be positioned and engaged with the first positioning part 31. That is, the first positioning part 525 can be provided on both the valve island bracket 52 and the valve island body 51, and the first positioning part 31 can be positioned and engaged with the two first positioning parts 525 respectively, so that the valve island bracket 52 and the valve island body 51 can be installed together on the gas-liquid separator 3, and the installation method is flexible.

[0100] In some other embodiments, the air conditioner 100 also includes a connection structure 8 for connecting the gas-liquid separator 3 to the valve island support 52, or the connection structure 8 is connected in sequence to the valve island support 52 and the valve island body 51.

[0101] Specifically, the air conditioner 100 is also provided with a connecting structure 8. The connecting structure 8 can be made of bolts, etc., which is simple in structure and low in installation cost. The connecting structure 8 is used to connect the gas-liquid separator 3 to the valve island bracket 52, or the connecting structure 8 is connected to the valve island bracket 52 and the valve island body 51 in sequence. That is, in actual installation, the valve island bracket 52 can be connected to the gas-liquid separator 3 first through the connecting structure 8, such as... Figure 3 As shown, the valve island bracket 52 is provided with a connection hole 527. The connection structure 8 can be inserted into the connection hole 527 to connect the valve island bracket 52 to the gas-liquid separator 3. Then, the valve island body 51 is connected to the valve island bracket 52. Alternatively, the valve island bracket 52 and the valve island body 51 can be connected to the gas-liquid separator 3 in sequence through the connection structure 8. The installation method is flexible, and both the valve island bracket 52 and the valve island body 51 are detachable from the gas-liquid separator 3 to improve the convenience of later maintenance and save maintenance time.

[0102] In addition, the valve island support 52 can be connected to the gas-liquid separator 3 by welding or other means, and the valve island body 51 is connected to the valve island support 52 through the connecting structure 8, so that the valve island body 51 is detachable relative to the valve island support 52, which can also improve the convenience of later maintenance and save maintenance time.

[0103] In actual installation, the valve island bracket 52 can be installed on the gas-liquid separator 3 first, and the flow path integration module 4 and the valve island body 51 can be pre-installed. Then, the pre-installed flow path integration module 4 and the valve island body 51 can be installed together on the valve island bracket 52, which can improve installation efficiency, save installation time, and reduce production costs. Leak detection can be performed after pre-installation, which can save final assembly welding time, reduce the number of weld points during final assembly, reduce the probability of leakage during final assembly, and improve installation reliability.

[0104] In some embodiments, the first positioning part 31 is one, and the connecting structure 8 is two, with the two connecting structures 8 symmetrically distributed on both sides of the first positioning part 31.

[0105] Specifically, the gas-liquid separator 3 may be provided with a first positioning part 31, and the first positioning part 31 may be set as one. The valve island bracket 52 may be positioned and engaged with the first positioning part 31 through the first positioning mating part 525 to ensure installation accuracy. The connecting structure 8 may be set as two, and the two connecting structures 8 may be symmetrically distributed on both sides of the first positioning part 31. This ensures that when the valve island bracket 52 is installed in the gas-liquid separator 3, the two connecting structures 8 are subjected to the same force, which can avoid problems such as deformation or connection failure caused by excessive force on one of the connecting structures 8, so as to ensure connection reliability.

[0106] In other embodiments, the gas-liquid separator 3 is provided with at least one second positioning part, which is spaced apart from the first positioning part 31. The second positioning part is positioned and engaged with the valve island support 52, or the second positioning part is positioned and engaged with the valve island support 52 and the valve island body 51 in sequence.

[0107] Specifically, the gas-liquid separator 3 is also provided with a second positioning part. The second positioning part can be at least one, that is, one, two or three, etc. The second positioning part can be a positioning protrusion or a positioning groove, etc. The valve island bracket 52 is also provided with a second positioning mating part 526. The second positioning mating part 526 can also be a positioning protrusion or a positioning groove, etc. The second positioning part and the second positioning mating part 526 are provided in a one-to-one correspondence, so that when the valve island bracket 52 is installed on the gas-liquid separator 3, the second positioning part can be positioned and mated with the second positioning mating part 526 to improve the installation accuracy.

[0108] In addition, a second positioning and mating part 526 can be provided on the valve island body 51, so that the second positioning part can be positioned and mated with the valve island bracket 52 and the valve island body 51 in sequence, so as to ensure the accuracy when the valve island bracket 52 and the valve island body 51 are installed together in the gas-liquid separator 3. The second positioning part is spaced apart from the first positioning part 31, so that if one of the two positioning parts is damaged, the other can still be positioned, thus ensuring the reliability of positioning.

[0109] In some embodiments, the valve island support 52 is connected to the gas-liquid separator 3 by welding, or the valve island support 52 is detachably connected to the gas-liquid separator 3. The valve island support 52 can be installed on the gas-liquid separator 3 by welding, which is convenient for installation. Alternatively, the valve island support 52 can be detachably installed on the gas-liquid separator 3 by means of connectors, such as bolts or rivets, which has low installation cost and facilitates later maintenance, saving maintenance time. Furthermore, the valve island support 52 and the gas-liquid separator 3 can be made of the same or different materials, which is flexible in terms of installation method.

[0110] In other embodiments, the valve island body 51 and the valve island support 52 are connected by welding, or the valve island body 51 and the valve island support 52 are detachably connected. The valve island body 51 can be installed on the valve island support 52 by welding, which is convenient for installation. Alternatively, the valve island body 51 can be detachably installed on the valve island support 52 by means of connectors, such as bolts or rivets, which has low installation cost and facilitates later maintenance, saving maintenance time. Furthermore, the valve island body 51 and the valve island support 52 can be made of the same or different materials, which is flexible in terms of installation method.

[0111] In some embodiments, the weight of the valve island body 51 is W, and satisfies: 50g≤W≤2334g.

[0112] In related technologies, air conditioning systems include multiple components that are connected to each other through pipes. However, current pipe connections require welding multiple pipe sections together, and pipe bends must have straight sections and bending radii. Both straight sections and bending radii have a minimum size, which leads to complex pipework, heavy pipework, high cost, and inconvenient installation.

[0113] Understandably, in response to the core problem of the need for welding connections between multiple pipe sections in related technologies, and the complexity of pipe structures due to process requirements for straight sections and minimum bending radii, at least one fluid channel integrated inside the valve island body 51 provides a structural replacement for traditional multi-section welded pipes. The fluid conduction function is accomplished by the integrally formed fluid channel inside the valve island body 51, avoiding the need for welding and splicing of multiple pipe sections, and also avoiding the need to reserve redundant straight sections and minimum bending radii to meet pipe bending processes. This eliminates the structural redundancy caused by splicing and process limitations in traditional pipe systems, simplifying the pipe structure. At the same time, the valve island body 51 needs to achieve load-bearing function through support components to ensure the stability of the connection with the pipe. In this supported state, the vibration generated by the operation of the compressor 2 will be transmitted to the valve island body 51 along the pipeline. If the valve island body 51 is too light, its own inertia is not enough to offset the vibration impact, which will cause excessive vibration at the connection between the valve island body 51 and the pipeline, and at the same time cause high-frequency vibration of the valve island body 51. If the valve island body 51 is too heavy, although it can enhance the vibration resistance, it will increase the load on the support components and the overall weight of the system, which does not meet the requirements of lightweighting.

[0114] Therefore, based on the above-mentioned vibration transmission characteristics and support stability requirements, this utility model limits the weight of the valve island body 51 to a specific threshold range. This range can ensure that the valve island body 51, under the support of the support member, can form sufficient inertia through its own weight to suppress the vibration of the connection part and the body caused by the vibration transmission of the compressor, and avoid reliability problems such as sealing failure and loosening of internal components of the valve island body 51 caused by vibration. It can also avoid the increase in system burden caused by excessive weight, thereby meeting the reliability requirements of the support member while taking into account the lightweight design goal of the system.

[0115] Furthermore, the weight composition of a conventional piping system includes the weight of pipes in multiple sections, the weight of welded connections, and the additional weight of pipes in redundant straight sections and bends. The aforementioned weight is replaced by the valve island body 51, and the weight of the valve island body 51 is in the range of 50g to 2334g, which is lower than that of a conventional transmission system composed of multiple pipes and welded connections under the same fluid transmission conditions.

[0116] Understandably, in fluid transmission scenarios involving small valve island bodies 51 with low flow rates and short distances, traditional solutions require splicing multiple pipe sections to meet the requirements. However, because each pipe section needs to reserve a minimum straight section and bending radius, its total weight will still exceed 50g. In contrast, the valve island body 51 achieves the same conduction function with a weight of only 50g, while reducing weight and having sufficient inertia to suppress vibration of the connection parts and the body itself caused by compressor vibration transmission. The weight limit of 2334g is suitable for the fluid transmission system requirements of medium and large valve island bodies 51. For traditional systems that require splicing multiple long pipe sections and include multiple bending nodes, the total weight often significantly exceeds 2334g due to the increase in pipe material usage and the number of welded parts. The valve island body 51, through the integration of internal multi-fluid channels, can replace multiple sets of traditional pipes. When meeting the requirements of larger flow rates or multi-path transmission, the weight is still controlled within 2334g, avoiding the problems of excessive weight, increased cost, and installation difficulties caused by the increase in the number of pipes in traditional systems.

[0117] When W is less than 50g, the size of the valve island body 51 needs to be significantly reduced due to weight constraints. Integrating at least one fluid channel and opening at least two interfaces within this reduced size makes it difficult for the inner diameter of the fluid channel and the structural strength of the body to meet basic fluid transmission requirements. This can result in either an excessively small inner diameter of the fluid channel, preventing effective fluid flow, or an excessively thin wall thickness of the valve island body 51, making it prone to structural damage under installation, docking, or fluid pressure. Consequently, it cannot replace traditional multi-section piping to complete the fluid transmission function, nor can it achieve the core goal of weight reduction. Furthermore, when W is less than 50g, the inertia generated by the mass of the valve island body 51 itself is insufficient to offset the vibration energy transmitted by the compressor through the piping. When the compressor vibration is transmitted along the support to the connection point of the valve island body 51, the valve island body 51, due to its insufficient inertia, cannot form effective vibration damping and will generate high-frequency, large-amplitude vibrations synchronously with the vibration energy. Excessive vibration can directly cause repeated stress impacts at the connection of the valve island body 51, which can easily lead to failure of the interface sealing structure and refrigerant leakage. At the same time, the valve core, electromagnetic coil and other precision components inside the valve island body 51 may also shift in position or loosen between components due to continuous vibration, which can damage the normal on / off control function of the valve island and ultimately lead to a decrease in the reliability of the air conditioning system, making it unable to meet the basic reliability requirements under the premise of pipe support.

[0118] When W is greater than 2334g, the weight of the valve island body 51, which exceeds 2334g, will be close to or even exceed the total weight of some medium and large traditional pipeline systems, and will not be able to demonstrate the weight advantage over traditional pipelines. At the same time, the excessive weight of the valve island body 51 will increase the difficulty of handling during installation, and a more stable fixing structure needs to be designed to support its weight, which will lead to a decrease in the convenience of installation.

[0119] It should be noted that traditional pipeline systems require welding, positioning, and bending operations section by section, which is cumbersome and prone to sealing failure due to welding quality. In contrast, valve island assembly 5 can be connected to external components through the interface on the surface of valve island body 51, which simplifies the installation process. At the same time, the integrated fluid channel avoids the sealing risks caused by too many welding points.

[0120] In short, by setting up a valve island body 51, at least one fluid channel integrated inside the valve island body 51 can directly replace the original multi-section welded pipeline. The fluid channel achieves fluid conduction through the pre-set integrated fluid channel inside the valve island body 51, eliminating the need for additional pipeline splicing and redundant straight sections and bending radii to meet bending process requirements, thus simplifying the fluid transmission path. Since the material consumption and welding connection consumption of the original multi-section pipeline are replaced by the integrated fluid channel, the overall weight is significantly reduced compared to the traditional transmission system composed of multi-section pipelines and welded parts. Moreover, there is no need to perform segmented welding, positioning, and bending operations on the multi-section pipeline; it only requires docking with external components through at least two interfaces on the surface of the valve island body 51, reducing installation procedures and operational difficulty, and avoiding the sealing reliability risks caused by pipeline welding.

[0121] According to some embodiments of the present invention, the valve island assembly 5 has a valve island body 51 constructed of aluminum and its weight satisfies: 50g≤W≤975g.

[0122] Understandably, the valve island body 51 is constructed of aluminum, which inherently possesses low density. Combined with its integrated fluid channels, it can replace traditional multi-section welded pipes, eliminating the redundant weight generated by splicing and bending processes in traditional pipes. Furthermore, the low density of aluminum further amplifies the weight optimization effect, allowing the weight to be controlled within a reasonable range while ensuring fluid conduction. If the valve island body 51 weighs less than 50g, even with the low density of aluminum, integrating at least one fluid channel and opening at least two interfaces on such a lightweight body would result in insufficient structural strength, making it impossible to replace the function of traditional pipes. When the weight of the valve island body 51 exceeds 975g, although the density of aluminum is lower than that of traditional pipes, the weight of the aluminum valve island body 51 that exceeds the standard will be close to or even exceed that of the traditional pipeline system under the same fluid transmission conditions, and the weight advantage cannot be reflected. The range of 50g≤W≤975g not only makes use of the characteristics of aluminum to ensure that the body has sufficient strength and normal channel function while being lightweight, but also avoids losing the advantage due to excessive weight. At the same time, the ease of processing aluminum allows for more precise forming of the fluid channel, ensuring stable fluid transmission.

[0123] According to some embodiments of the present invention, the valve island assembly 5 has a valve island body 51 constructed of stainless steel and its weight satisfies: 765g≤W≤2334g.

[0124] Understandably, stainless steel possesses high strength and corrosion resistance, making it suitable for scenarios requiring stable fluid transmission, pressure resistance, and resistance to media corrosion. Similarly, the internally integrated fluid channel can replace traditional multi-section welded pipes, eliminating structural redundancy caused by splicing and bending processes in traditional pipes. Stainless steel has a higher density than aluminum, and this weight range ensures that the body has sufficient wall thickness to maintain high strength and meet structural stability requirements under fluid pressure. At the same time, the integrated fluid channel avoids redundant weight in traditional pipes, achieving weight optimization compared to traditional multi-section stainless steel pipes and achieving the core goal of reducing overall weight. Furthermore, the corrosion resistance of stainless steel prevents fluid media from eroding the channel, extending the module's service life and ensuring long-term reliable operation.

[0125] If the valve island body 51 weighs less than 765g, due to the high density of stainless steel, controlling the weight within this range would require a significant reduction in the body wall thickness and volume. This would result in an excessively small inner diameter of the fluid channel, failing to meet normal flow requirements. Simultaneously, an excessively thin wall thickness would lead to insufficient structural strength, making the body prone to deformation or even breakage during installation, connection, or under fluid pressure. This would prevent the realization of basic fluid transmission functions and would also negate the strength advantages of stainless steel, thus losing its value as a replacement for traditional pipelines. If the valve island body 51 weighs more than 2334g, although it may improve structural strength and channel capacity, an excessively heavy valve island body 51 would increase the difficulty of installation and handling, requiring additional fixing structures and reducing installation convenience. The range of 765g≤W≤2334g allows for the effective replacement of traditional multi-section pipelines while ensuring sufficient strength of the valve island component 5, meeting the requirements for fluid transmission and corrosion resistance, thus achieving the technical effects of weight reduction and simplified installation.

[0126] According to some embodiments of the present invention, a fluid channel is formed inside the valve island body 51, and multiple connection ports communicating with the fluid channel are formed on the surface of the valve island body 51; and the following conditions are met: 50g≤W≤150g.

[0127] Understandably, the valve island body 51 has a fluid channel inside. A single fluid channel achieves the conduction of multiple connection ports through the integrated structure inside the valve island body 51. This can replace the multi-section welded pipes used for fluid transmission between two points in traditional scenarios. There is no need to reserve redundant straight sections and bending radii to meet the bending process, nor is there a need for additional welded connectors. The weight range of 50g to 150g makes the weight of the valve island body 51 significantly lower. At the same time, external docking can be completed through only two interfaces, which greatly simplifies the installation process and improves assembly convenience. At the same time, the weight range of 50g to 150g ensures that the valve island body 51 has sufficient wall thickness to support the formation of the fluid channel, avoiding insufficient structural strength of the body due to the processing of the fluid channel. It also maintains the miniaturization characteristics, making it suitable for scenarios with compact installation space requirements. Furthermore, the lightweight design further reduces the difficulty of positioning and fixing during installation, indirectly improving the overall assembly efficiency of the system.

[0128] According to some embodiments of the present invention, the valve island body 51 includes a first plate and a second plate, the first plate and the second plate are attached to each other in the thickness direction, a fluid channel groove is formed on at least one wall surface of the first plate and the second plate facing each other, a fluid channel is defined in the fluid channel groove between the first plate and the second plate, and a connection port communicating with the fluid channel is formed on one of the first plate and the second plate.

[0129] Therefore, by bonding the first plate and the second plate together in the thickness direction, and providing fluid channel grooves on their opposing walls, a fluid channel is formed between the plates after bonding. This replaces the traditional refrigerant or gas medium transport path formed by welding segmented pipes. This structure eliminates the need to consider the gaps that must be reserved when connecting segmented pipes in traditional systems, as well as the minimum straight section size and minimum bending radius of the pipes. This significantly improves the integration of the air conditioning piping system and reduces the space occupied by the air conditioning piping. Compared with the traditional scattered segmented pipe setup, it significantly reduces space occupation. At the same time, since it is not necessary to form a medium passage by welding multiple pipe segments, it directly reduces the large number of weld points generated by welding connections in traditional systems, avoiding the problem of numerous weld points.

[0130] According to some embodiments of the present invention, the connection port structure has two or more, and at least one is provided on the first plate and the second plate respectively; or the connection port structure has multiple, and the multiple connection ports are arranged on the first plate or the second plate.

[0131] The arrangement of the above-mentioned connection ports can be adapted to the fluid channel between the first plate and the second plate. At least one connection port is provided on the first plate and the second plate respectively. Since each plate carries at least one connection port and each port is connected to the fluid channel between the plates, the medium can enter the fluid channel from the port of one plate and flow out from the port of the other plate. This allows for more flexible matching of the medium connection requirements of external components at different locations. There is no need to adjust the orientation or position of the ports through additional pipe connections, which shortens the transport path of the medium between the external components and the fluid channel and reduces the space occupied by the path.

[0132] As for the connection ports, all of which are arranged on the first or second plate, multiple interfaces are concentrated on the same plate and connected to the fluid channel. This allows the media connection ends of multiple external components to be concentrated on the same side of the valve module assembly, which facilitates the centralized arrangement and management of external pipelines, reduces the crossing or detour of external pipelines due to their dispersed connection to different plates, and reduces the complexity of the external pipeline system.

[0133] According to some embodiments of the present invention, the thickness of the first plate is n, the thickness of the second plate is m, and the depth of the fluid channel groove is d, satisfying: 0 < d / m ≤ 10, 0 < d / n ≤ 10.

[0134] It is understandable that when 0 < d / m ≤ 1 and 0 < d / n ≤ 1, the depth of the fluid channel groove is less than the corresponding plate thickness. This means that the fluid channel groove is only opened inside the plate and does not penetrate the plate. At this time, the ungrooved area of ​​the plate can form a complete structural support, which can effectively resist the pressure impact generated when the refrigerant flows in the channel, and avoid the structural strength reduction of the plate due to excessive groove depth. At the same time, the shallower fluid channel groove can make the fluid channel formed after the two plates are attached have a more uniform wall thickness, reduce the local stress concentration caused by uneven wall thickness, and ensure the structural reliability of the channel in long-term operation.

[0135] When 1 < d / m ≤ 10 and 1 < d / n ≤ 10, the depth of the fluid channel groove is greater than the corresponding plate thickness. In this case, the fluid channel groove can form a deeper recess on the plate. With the adhesion of another plate, a fluid channel with a larger cross-sectional area can be constructed, improving the refrigerant flow capacity and meeting the demand for high-flow refrigerant transportation. At the same time, although the groove depth in this range exceeds the plate thickness, the limitation of d / m ≤ 10 and d / n ≤ 10 can prevent the fluid channel groove from being too deep, which would result in the remaining structure of the plate being too thin. This ensures that the plate can still maintain its basic load-bearing capacity and prevents deformation during assembly or use. By controlling the ratio of the fluid channel groove depth to the plate thickness, a balanced optimization of the fluid channel function and the plate structure performance is achieved without changing the basic structure of the plate and the fluid channel groove.

[0136] In some embodiments of this utility model, such as Figures 8-13As shown, the air conditioner 100 also includes a reversing valve 43, an expansion valve 44, a solenoid valve 45, a plate heat exchanger 41, a high-pressure valve 46, and a low-pressure valve 47. The reversing valve 43, expansion valve 44, solenoid valve 45, plate heat exchanger 41, high-pressure valve 46, and low-pressure valve 47 are all connected to the valve island assembly 5. The valve island assembly 5 can integrate the functional components 30, reversing valve 43, expansion valve 44, solenoid valve 45, plate heat exchanger 41, high-pressure valve 46, and low-pressure valve 47 together to form a complete flow path. The welding between them can be completed in pre-assembly and leak-tested, saving the welding time and welding points in the final assembly, reducing the probability of leakage at the welding points in the final assembly, which is conducive to improving the assembly efficiency of the final assembly and facilitating the improvement of production efficiency and reliability.

[0137] For example, in some embodiments, the oil-gas separator 42 can separate the refrigerant oil discharged from the compressor 2 to ensure the reliable operation of the compressor 2. The oil-gas separator 42 can be connected to the compressor 2 and the reversing valve 43 respectively. The reversing valve 43 can be used to switch between cooling and heating modes and change the refrigerant flow direction. In cooling mode, the reversing valve 43 can be connected to the plate heat exchanger 41. At this time, the plate heat exchanger 41 can act as a condenser, where high-temperature and high-pressure gas releases heat and condenses into a high-pressure liquid. In heating mode, the reversing valve 43 can be connected to the indoor unit of the air conditioner. At this time, the plate heat exchanger 41 acts as an evaporator, where low-temperature and low-pressure liquid absorbs heat and vaporizes. The plate heat exchanger 41 is also connected to the expansion valve 44. It can throttle and reduce pressure, regulate refrigerant flow, and ensure the reliability of air conditioning equipment operation; the high-pressure valve 46 can connect to the high-pressure pipeline between the outdoor unit and the indoor unit of the air conditioner 100. For example, the high-pressure valve 46 can connect to the high-pressure pipeline between the plate heat exchanger 41 and the indoor unit of the air conditioner, and is usually located at the outlet of the plate heat exchanger 41 or the expansion valve 44; the low-pressure valve 47 connects to the low-pressure pipeline between the outdoor unit and the indoor unit of the air conditioner 100. For example, the low-pressure valve 47 connects to the low-pressure pipeline between the plate heat exchanger 41 and the indoor unit of the air conditioner, and is usually connected to the reversing valve 43 or the gas-liquid separator 3. The gas-liquid separator 3 can store excess refrigerant to prevent liquid refrigerant from entering the compressor 2 and ensure the reliability of the compressor 2 operation. For example, the solenoid valve 45 can be a single-way solenoid valve 45, which can control the flow of refrigerant, such as cutting off part of the circuit during defrosting. The single-way solenoid valve 45 can be connected in series in the high-pressure pipeline or the bypass pipeline to increase the application scenarios of the air conditioner 100.

[0138] In some embodiments, the oil-gas separator 42, the reversing valve 43, the expansion valve 44, the solenoid valve 45, the high-pressure valve 46, and the low-pressure valve 47 are formed as a flow path integrated module 4, and the oil-gas separator 42, the reversing valve 43, the expansion valve 44, the solenoid valve 45, the high-pressure valve 46, and the low-pressure valve 47 are all connected to the valve island assembly 5.

[0139] Specifically, the flow path integration module 4 is disposed within the compressor cavity 11 and is connected to the valve island assembly 5, such as... Figure 8 As shown, the flow path integrated module 4 includes an oil-gas separator 42, a reversing valve 43, an expansion valve 44, a solenoid valve 45, a high-pressure valve 46, and a low-pressure valve 47. The oil-gas separator 42 can separate the refrigeration oil discharged from the compressor 2 and return it to the compressor 2 through the return oil pipeline to ensure the reliability of the compressor 2. The oil-gas separator 42 can be connected to the compressor 2 and the reversing valve 43 respectively.

[0140] According to some embodiments of the present invention, a compressor chamber 11 and a fan chamber 13 are formed separately inside the housing 1. A fan assembly is installed in the fan chamber 13. The valve island assembly 5 and the functional components 30 are installed in the compressor chamber 11. This can meet the placement requirements of different components, avoid the different components from affecting each other when the air conditioner 100 is working, ensure the working reliability of the air conditioner 100, and ensure a compact structure that reduces the space occupied.

[0141] In some embodiments, such as Figures 9-11 As shown, a partition 12 is provided inside the shell 1. The partition 12 can be connected to the shell 1 by means of connectors or welding. The connectors can be bolts, etc. The structure is simple, easy to install, and has low installation cost. An installation space is formed inside the shell 1, and the partition 12 can divide the installation space into a fan chamber 13 and a compressor chamber 11. A fan assembly can be installed in the fan chamber 13. The fan assembly is equipped with a drive motor, fan blades, and a plate heat exchanger 41, etc. The drive motor can drive the fan blades to rotate, and when the fan blades rotate, they can dissipate heat and cool the plate heat exchanger 41 to ensure the stability of the heat exchanger operation.

[0142] Therefore, the fan cavity 13 and the compressor cavity 11 are separated by a partition 12, so that when the drive motor, fan blades and compressor 2 are running, the partition 12 can block the vibration between the fan cavity 13 and the compressor cavity 11, so as to avoid interference between the structure in the fan cavity 13 and the structure in the compressor cavity 11, and ensure the reliability of the air conditioner 100.

[0143] In some embodiments, the compressor assembly can be installed inside the compressor chamber 11, which can meet the placement requirements of different components, avoid the different components from affecting each other when the air conditioner 100 is working, ensure the working reliability of the air conditioner 100, and ensure a compact structure that reduces the space occupied.

[0144] In some embodiments, a compressor assembly may be installed inside the housing 1. The compressor assembly includes a compressor 2 and a gas-liquid separator 3. The compressor 2 and the gas-liquid separator 3 are arranged side by side in the compressor cavity 11 and are both mounted and supported on the bottom wall of the housing 1.

[0145] Specifically, the compressor cavity 11 is equipped with a compressor 2 and a gas-liquid separator 3, which are spaced apart and arranged side by side within the compressor cavity 11. This avoids interference between the compressor 2 and the gas-liquid separator 3, ensuring the reliability of their operation. Both the compressor 2 and the gas-liquid separator 3 are mounted and supported on the bottom wall of the housing 1. The compressor 2 can be detachably mounted on the bottom wall of the housing 1 via connectors, facilitating maintenance and replacement of the compressor 2. Similarly, the gas-liquid separator 3 can also be detachably mounted on the bottom wall of the housing 1 via connectors, facilitating maintenance and replacement of the gas-liquid separator 3. This saves on the maintenance time and costs of the air conditioner 100 in the later stages of maintenance.

[0146] In some embodiments, a compressor assembly may be installed inside the housing 1. The compressor assembly includes a compressor 2 and a gas-liquid separator 3. Both the compressor 2 and the gas-liquid separator 3 are located below the valve island assembly 5. The top of the gas-liquid separator 3 is connected to the valve island assembly 5. The top of the compressor 2 is spaced apart from the valve island assembly 5 to jointly define a partition space 7.

[0147] Specifically, the valve island assembly 5 is installed on top of the gas-liquid separator 3, and the length of the compressor 2 is set to be less than the length of the gas-liquid separator 3, so that the compressor 2 and the gas-liquid separator 3 can both be set below the valve island assembly 5, and the top of the compressor 2 is spaced apart from the valve island assembly 5, that is, there is a height difference between the top of the compressor 2 and the top of the gas-liquid separator 3, which in turn defines the partition space 7, so that the valve island assembly 5 can be located in the partition space 7, and the vertical projection of the valve island assembly 5 overlaps at least partially with the vertical projection of the compressor 2, which can improve the utilization rate of the space in the compressor cavity 11, thereby reducing the space occupied by the air conditioner 100 and improving the lightweight of the air conditioner 100.

[0148] In some embodiments, the air conditioner 100 further includes a gas separator mounting bracket 6, through which the gas-liquid separator 3 is detachably connected to the bottom wall of the housing 1.

[0149] Specifically, such as Figures 1-2 , Figures 4-6 , Figure 9 , Figures 11-13As shown, the air conditioner 100 is also provided with a gas separator mounting bracket 6, which is installed at the bottom of the gas-liquid separator 3. The gas-liquid separator 3 can be detachably connected to the bottom wall of the housing 1 through the gas separator mounting bracket 6. That is, the gas-liquid separator 3 can be connected to the gas separator mounting bracket 6 through connectors, and the gas separator mounting bracket 6 can also be connected to the bottom wall of the housing 1 through connectors. This makes the gas-liquid separator 3 detachable from the bottom wall of the housing 1, which facilitates the later maintenance of the gas-liquid separator 3. Furthermore, the connection between the gas-liquid separator 3 and the bottom wall of the housing 1 through the gas separator mounting bracket 6 reduces the contact area between the gas-liquid separator 3 and the housing 1, thereby reducing the vibration transmitted from the gas-liquid separator 3 to the housing 1, reducing the noise generated by the air conditioner 100 during operation, and improving the user experience.

[0150] In some embodiments, the gas separator mounting bracket 6 includes a top mounting plate 61, a middle plate 62, and a bottom mounting plate 63. The top mounting plate 61 and the bottom mounting plate 63 are spaced apart and opposite to each other and connected to the two ends of the middle plate 62. The bottom of the gas-liquid separator 3 is supported by the top mounting plate 61, and the bottom mounting plate 63 is supported by the bottom wall of the housing 1.

[0151] Specifically, the gas-liquid separator 3 can be detachably connected to the bottom wall of the housing 1 via the gas separation mounting bracket 6, and as shown... Figure 4 As shown, the gas separator mounting bracket 6 is provided with a top mounting plate 61, a middle plate 62 and a bottom mounting plate 63. The top mounting plate 61 and the bottom mounting plate 63 are both arranged horizontally and are spaced apart vertically. The middle plate 62 extends vertically and its upper and lower ends are connected to the top mounting plate 61 and the bottom mounting plate 63 respectively. The bottom of the gas-liquid separator 3 is detachably connected and supported by the top mounting plate 61, and the bottom mounting plate 63 is detachably connected and supported by the bottom wall of the housing 1.

[0152] By arranging both the mounting top plate 61 and the mounting bottom plate 63 horizontally, the contact area between the mounting top plate 61 and the bottom of the gas-liquid separator 3, as well as the contact area between the mounting bottom plate 63 and the bottom wall of the housing 1, can be increased, ensuring the reliability of the support. Furthermore, by extending the intermediate plate 62 vertically, the connection area between the intermediate plate 62 and the mounting top plate 61 and the mounting bottom plate 63 can be reduced, thereby reducing the transmission of vibration, reducing the noise generated by the air conditioner 100 during operation, and improving user comfort.

[0153] In addition, a gas-liquid separator mounting bracket 6 is provided at the bottom of the gas-liquid separator 3, so that there is a height difference between the top of the gas-liquid separator 3 and the top of the compressor 2. This allows the valve island assembly 5 to be staggered from the top of the compressor 2, avoiding interference between the structures and ensuring the operational reliability of each structure. Both the mounting top plate 61 and the mounting bottom plate 63 are provided with a second limiting flange 64. The second limiting flange 64 of the mounting top plate 61 can limit the gas-liquid separator 3 to ensure installation reliability, and the second limiting flange 64 of the mounting bottom plate 63 can improve the structural strength of the mounting bottom plate 63 to ensure the reliability of the support for the gas-liquid separator 3.

[0154] In some embodiments of this utility model, such as Figure 8 , Figure 9 , Figures 11-15 As shown, the air conditioner 100 also includes a reversing valve 43, which is located inside the housing 1. A first connecting pipe 23 connects the reversing valve 43 and the valve island assembly 5. Refrigerant can flow between the reversing valve 43 and the valve island assembly 5 through the first connecting pipe 23. The length of the first connecting pipe 23 is S1, and satisfies: S1≤400mm. It can be understood that the length of the first connecting pipe 23 can be 40mm, 80mm, 120mm, 160mm, 200mm, 240mm, 280mm, 320mm, 360mm, or 400mm. The length of the first connecting pipe 23 not exceeding 400mm ensures normal refrigerant flow while preventing the distance between the reversing valve 43 and the valve island assembly 5 from being too large or too small, making the positioning of the reversing valve 43 relatively reliable.

[0155] Specifically, both ends of the first connecting pipe 23 extend into the interfaces of the valve island assembly 5 and the reversing valve 43. The length of the first connecting pipe 23 refers to the length between the free end face of the interface of the valve island assembly 5 connected to the first connecting pipe 23 and the free end face of the interface of the reversing valve 43 connected to the first connecting pipe 23, excluding the portion of the first connecting pipe 23 that extends into the interfaces of the valve island assembly 5 and the reversing valve 43.

[0156] If the materials at the connection points of the first connecting pipe 23 and the valve island assembly 5 are different, a copper sleeve needs to be installed at the interface of the valve island assembly 5 to ensure the reliability of the connection between the first connecting pipe 23 and the valve island assembly 5. The length of the copper sleeve is the same as the length of the first connecting pipe 23. Alternatively, if the materials at the connection points of the first connecting pipe 23 and the reversing valve 43 are different, a copper sleeve needs to be installed at the interface of the reversing valve 43 to ensure the reliability of the connection between the first connecting pipe 23 and the reversing valve 43. The length of the copper sleeve is the same as the length of the first connecting pipe 23. Or, if the materials at the connection points of the first connecting pipe 23 and both the valve island assembly 5 and the reversing valve 43 are different, a copper sleeve needs to be installed at both the interface of the valve island assembly 5 and the reversing valve 43 to ensure the reliability of the connection between the first connecting pipe 23 and both the reversing valve 43 and the valve island assembly 5. The lengths of the copper sleeves at both ends of the first connecting pipe 23 are both the same as the length of the first connecting pipe 23.

[0157] The length of the first connecting pipe 23 is no more than 400mm. While ensuring the normal flow of refrigerant, firstly, it can avoid the first connecting pipe 23 being too long, thus avoiding the first connecting pipe 23 occupying too much space inside the housing 1, improving the integration of the reversing valve 43, the first connecting pipe 23 and the valve island assembly 5, and facilitating the layout of other structures within the air conditioner 100; secondly, it can reduce the flow path of refrigerant between the reversing valve 43 and the valve island assembly 5, reduce refrigerant loss, and ensure the cooling effect of the air conditioner 100.

[0158] Thirdly, the reversing valve 43 and the valve island assembly 5 are connected by the first connecting pipe 23. The reversing valve 43 and the valve island assembly 5 can be supported by the first connecting pipe 23. The length of the first connecting pipe 23 is relatively short, and the supporting force between the reversing valve 43 and the valve island assembly 5 is good. For example, the valve island assembly 5 can be installed and supported on the housing 1 by means of connectors or welding. The first connecting pipe 23 supports the reversing valve 43, realizing the installation of the reversing valve 43. When the length of the first connecting pipe 23 is relatively short, the rigidity of the first connecting pipe 23 can be increased, and the supporting effect of the first connecting pipe 23 on the reversing valve 43 is good. At the same time, the internal structure of the air conditioner 100 is subject to vibration. If the length of the first connecting pipe 23 is not too short, the connection stress between the reversing valve 43 and the valve island assembly 5 can be reduced, thereby improving the service life of the reversing valve 43 and the valve island assembly 5.

[0159] In some embodiments, such as Figure 15 As shown, the distance between the axis of the reversing valve 43 and the valve island assembly 5 is S2, and satisfies: S2≤420mm.

[0160] Here, the distance between the axis of the reversing valve 43 and the valve island assembly 5 refers to the vertical distance between the axis of the reversing valve 43 and the free end face of the interface of the valve island assembly 5. The distance between the axis of the reversing valve 43 and the valve island assembly 5 is no greater than 420mm. This avoids the reversing valve 43 occupying too much space above the valve island assembly 5, confining it to a specified range above the valve island assembly 5, reducing the space occupied by the reversing valve 43 above the valve island assembly 5, improving the integration of the internal structure of the air conditioner 100, and reducing the space occupied by the reversing valve 43 and the valve island assembly 5.

[0161] In some embodiments, such as Figure 1 As shown, the reversing valve 43 is a four-way valve, and the interface at the bottom of the four-way valve has three ports.

[0162] In some embodiments of this utility model, such as Figures 11-13 As shown, the first connecting pipe 23 is along the vertical direction (e.g.) Figure 11 As shown in the vertical direction, the refrigerant flows through a shorter path between the reversing valve 43 and the valve island assembly 5, thus increasing the refrigerant flow efficiency.

[0163] In some embodiments of this utility model, such as Figure 9 , Figures 11-15 As shown, there are two first connecting pipes 23. One end of each first connecting pipe 23 is connected to two interfaces on the valve island assembly 5, and the other end is connected to two interfaces on the reversing valve 43. It can be understood that the four ports of the reversing valve 43 are connected to the gas-liquid separator 3, the compressor 2 and the interfaces on the two valve island assemblies 5, respectively, so as to realize the smooth flow of refrigerant in the fluid channel and meet different usage requirements.

[0164] In some embodiments of this utility model, such as Figures 9-14 As shown, the air conditioner 100 also includes an expansion valve 44, which precisely controls the refrigerant flow into other refrigeration components by controlling the opening of the corresponding fluid channel, thereby achieving high efficiency, energy saving, and precise temperature control. For example, the expansion valve 44 is an electronic expansion valve.

[0165] like Figure 13 As shown, the vertical distance between the top surface of the expansion valve 44 and the valve island assembly 5 is L1, and satisfies: L1≤540mm.

[0166] Here, the vertical distance between the top surface of the expansion valve 44 and the valve island assembly 5 refers to the vertical distance between the free end face of the interface of the valve island assembly 5 and the top surface of the expansion valve 44 after the expansion valve 44 is connected to one interface of the valve island assembly 5. This distance satisfies S3 not greater than 540mm, so as to avoid the expansion valve 44 occupying too much space in the vertical direction. The expansion valve 44 can be limited to the height range of the top pipe section 251 without protruding, so that the vertical placement space of the expansion valve 44 and the top pipe section 251 overlaps, reducing the space occupied by the expansion valve 44 on the second side 202, improving the integration and reducing the space occupied.

[0167] In some embodiments of this utility model, such as Figure 9 , Figures 11-14 As shown, the valve island assembly 5 is provided with a connection port communicating with the fluid channel. The housing 1 includes a top cover 14 and a bottom plate 15 arranged opposite each other in the vertical direction. The air conditioner 100 also includes a pipe assembly 9, which is connected to at least part of the connection port. The highest position of the part of the pipe assembly 9 located on the upper side of the valve island assembly 5 and opposite to the valve island assembly 5 in the vertical direction is the first position. The pipe assembly 9 and the top cover 14 together define an accommodating space 91 located above the first position.

[0168] In other words, the highest point of the portion of the pipe assembly 9 opposite to the valve island assembly 5 is spaced apart from the top cover 14 of the housing 1, and the accommodating space 91 is located above the highest point of the portion of the pipe assembly 9 opposite to the valve island assembly 5. Because the valve island assembly 5 is equipped with fluid channels, multiple different fluid channels can be integrated within it. This improves the integration of the fluid channels within the assembly, reducing the number of refrigerant pipes required for each channel. Consequently, by reducing the number of refrigerant pipes, the installation space occupied by the fluid channels is reduced, thus creating the accommodating space 91 located above the first position between the pipe assembly 9 and the top cover 14.

[0169] Therefore, by setting up the valve island assembly 5 and defining the receiving space 91 between the pipe assembly 9 and the top cover 14, more flexible options can be provided for the internal layout of the housing 1. For example, the electrical control box can be placed inside the receiving space 91, thereby reducing the difficulty of arranging the internal components of the housing 1 and improving the space utilization rate inside the housing 1. In addition, corresponding functional modules can be flexibly selected and installed in the receiving space 91 according to the needs of the air conditioner 100, thereby improving the flexibility of the function adjustment of the air conditioner 100. For example, an oxygen generation module can be added to the receiving space 91, enabling the air conditioner 100 to have the function of supplying oxygen to the room, etc.

[0170] According to some embodiments of this utility model, such as Figure 11As shown, the distance between the first position and the top cover 14 along the vertical direction is H1, and the distance between the top cover 14 and the bottom plate 15 is H2, where H1 / H2 ≥ 10%. This means that the height dimension of the accommodating space 91 along the vertical direction is not less than 10% of the distance between the top cover 14 and the bottom plate 15. This ensures that the accommodating space 91 has sufficient height along the vertical direction, thereby increasing its volume and enhancing its capacity, facilitating the arrangement of functional modules within it. The ratio of the height dimension of the accommodating space 91 along the vertical direction to the distance between the top cover 14 and the bottom plate 15 can be 10%, 12%, 15%, 18%, 20%, 22%, 24%, 26%, 28%, 30%, 32%, 35%, etc., without specific limitations.

[0171] According to some embodiments of this utility model, the distance between the first position and the top cover 14 in the vertical direction is not less than 6cm. That is, the height of the accommodating space 91 in the vertical direction is controlled to be not less than 6cm. Figure 2 The height H1 shown is controlled to be no less than 6cm. This ensures that the accommodating space 91 has sufficient height in the vertical direction, thereby increasing its volume and capacity, and facilitating the arrangement of functional modules within it. The height of the accommodating space 91 in the vertical direction can be 6cm, 8cm, 10cm, 12cm, 14cm, 16cm, 18cm, 20cm, 23cm, 25cm, etc., without specific limitations.

[0172] According to some embodiments of the present invention, the air conditioner 100 includes a reversing valve 43 and a third connecting pipe 25. The reversing valve 43 is located above the valve island assembly 5. The reversing valve 43 includes a first interface 54 and a second interface. The first interface 54 is located at the top of the reversing valve 43. The exhaust port of the compressor 2 is connected to the first interface 54 through the third connecting pipe 25. The highest position of the third connecting pipe 25 is the first position. The second interface is connected to the connecting port.

[0173] In other words, the highest point of all pipes in the piping assembly 9, except for the third connecting pipe 25, is no higher than the highest point of the third connecting pipe 25. The third connecting pipe 25 and the top cover 14 define a receiving space 91 located above the third connecting pipe 25. Since the first interface 54 is located at the top of the reversing valve 43, the end of the third connecting pipe 25 furthest from the compressor 2 needs to be wound upwards to the top of the reversing valve 43 to facilitate connection between the third connecting pipe 25 and the first interface 54. That is, the third connecting pipe 25 needs to extend to the top of the reversing valve 43 due to the position of the first interface 54. Therefore, by designating the highest point of the third connecting pipe 25 as the first position, it is possible to connect the third connecting pipe 25 to the first interface 54 while better controlling the height of the other pipes in the piping assembly 9, except for the third connecting pipe 25. Lowering the height of the first position allows the receiving space 91 to have a larger height dimension, thereby increasing the volume of the receiving space 91, facilitating the arrangement of functional modules, and achieving high space utilization.

[0174] The reversing valve 43 also includes a third interface and a fourth interface. At least a portion of the second, third, and fourth interfaces are connected to the connection port via the pipeline assembly 9 to switch the fluid passage within the valve island assembly 5.

[0175] According to some embodiments of this utility model, such as Figure 9 , Figures 11-14 As shown, the third connecting pipe 25 includes a top pipe section 251 and a connecting section. The top pipe section 251 is connected to the upper side of the connecting section and is located above the reversing valve 43. The two ends of the connecting section are connected to the compressor 2 and the first end of the top pipe section 251, respectively. The second end of the top pipe section 251 is connected to the first interface 54. The top pipe section 251 is U-shaped and opens downwards. The top position of the top pipe section 251 is the first position. That is, the connecting section is connected to the reversing valve 43 through the top pipe section 251. The exhaust port of the compressor 2 is located below the reversing valve 43. By setting the top pipe section 251, it is convenient for the third connecting pipe 25, which extends upwards from the lower side of the reversing valve 43, to connect to the first interface 54 at the top of the reversing valve 43, thereby reducing the difficulty of connecting the third connecting pipe 25 to the reversing valve 43. In addition, by setting a top pipe section 251 between the connecting section and the reversing valve 43, the third connecting pipe 25 can have a certain elastic deformation capacity at the position of the top pipe section 251, thereby avoiding the risk of the third connecting pipe 25 breaking due to the large shaking of the air conditioner 100 during transportation and installation, and thus improving the reliability of the connection between the third connecting pipe 25 and the compressor 2 and the reversing valve 43.

[0176] According to some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the piping assembly 9 includes a connecting pipe 33 and a heat dissipation pipe 32 connected to the valve island assembly 5. The valve island assembly 5 is connected to the outdoor heat exchanger of the air conditioner 100 via the connecting pipe 33. The heat dissipation pipe 32 is located at the electrical control box of the air conditioner 100 and is connected to a portion of the connection port. The height of the portions of the connecting pipe 33 and the heat dissipation pipe 32 relative to the valve island assembly 5 in the vertical direction is lower than the first position. That is to say, the valve island assembly 5 can supply refrigerant to the outdoor heat exchanger through the connecting pipe 33, allowing the refrigerant to dissipate heat within the outdoor heat exchanger. Furthermore, the valve island assembly 5 can supply refrigerant into the heat dissipation pipe 32. It should be noted that the heat dissipation pipe 32 can be installed on parts that require heat dissipation, such as the electrical control box. This allows the refrigerant within the heat dissipation pipe 32 to reduce the temperature of components requiring heat dissipation, such as the electrical control box, thereby ensuring the stability of their operation. Among them, the parts of the connecting pipe 33 and the heat dissipation pipe 32 that are opposite to the valve island assembly 5 in the vertical direction are all lower than the first position, which can prevent the connecting pipe 33 and the heat dissipation pipe 32 from extending into the accommodating space 91 and affecting the arrangement of the functional modules in the accommodating space 91.

[0177] According to some embodiments of this utility model, the air conditioner 100 further includes a functional module, at least a portion of which is housed within the housing space 91. The functional module can be an oxygen-generating module or an electrical control box. In other words, the housing space 91 can be flexibly utilized to accommodate portions of the functional module according to the design requirements of the air conditioner 100. For example, the functional module can be completely arranged within the housing space 91, or only a portion of the functional module can be arranged within the housing space 91. This improves the flexibility of arranging the functional module within the housing space 91.

[0178] In some embodiments of this utility model, such as Figure 9 , Figures 11-14 As shown, the air conditioner 100 also includes an expansion valve 44. The valve island assembly 5 is provided with a connection port communicating with the fluid channel. The expansion valve 44 and the connection port are connected through a second connecting pipe 24. The length of the second connecting pipe 24 is less than or equal to 540 mm. The length of the second connecting pipe 24 as defined in this utility model is the distance between the upper interface of the connection port and the two end faces of the valve port of the expansion valve 44, rather than the length of the second connecting pipe 24 itself. That is, the second connecting pipe 24 can be extended at an angle or bent to avoid surrounding structures. For example, the distance between the end face of the valve port of the main expansion valve and the end face of the interface on the valve island assembly 5 used to connect the main expansion valve is less than or equal to 540 mm, or the distance between the end face of the valve port of the enthalpy-increasing expansion valve and the end face of the interface on the valve island assembly 5 used to connect the enthalpy-increasing expansion valve is less than or equal to 540 mm.

[0179] It is understood that this utility model makes the length of the second connecting pipe 24 between the expansion valve 44 and the valve island assembly 5 more reasonable, which can reduce the length of the second connecting pipe 24, thereby reducing the piping length, reducing costs, and improving the overall space occupied by the valve island 5 and the second connecting pipe 24, reducing the difficulty of layout.

[0180] It should be noted that the expansion valve 44 can be arranged within the vertical (horizontal) projection outline of the valve island assembly 5, allowing for a smaller projected area and less space occupation of the valve island assembly 5. This enables a more compact design, reducing the difficulty of arranging the valve island assembly 5. Furthermore, it allows for a shorter internal fluid channel length, lower refrigerant flow resistance, and less heat loss, ensuring better temperature regulation capabilities and improving the energy efficiency ratio of the air conditioner. In other words, it further reduces the space occupied by the valve island assembly 5 itself, simplifying its arrangement. This allows for more space within the housing 1 for arranging expansion modules, improving the expandability of the air conditioner 100. The reduced internal fluid channel length of the valve island assembly 5, combined with the reduced piping length, effectively lowers refrigerant flow resistance, reducing losses, improving temperature regulation capabilities, and ultimately increasing the energy efficiency ratio and reducing energy consumption.

[0181] In related technologies, air conditioners have valve island assemblies, which are composed of multiple valve bodies and corresponding pipes and interfaces. For example, the valve island assembly is integrated into the compressor, but the compressor's pipes and the valve island's pipes occupy a large space, resulting in the compressor and valve island assembly occupying a lot of space and easily interfering with the layout of other structures in the air conditioner.

[0182] Therefore, in some embodiments of this utility model, such as Figures 9-14 As shown, the functional component 30 includes a compressor 2, which has an exhaust port. The air conditioner 100 includes a reversing valve 43, a third connecting pipe 25, and a fourth connecting pipe 26. The reversing valve 43 has a first interface 54 and a second interface that communicate with the fluid passage. The third connecting pipe 25 communicates with the exhaust port and the first interface 54. The third connecting pipe 25 has a top pipe section 251. The fourth connecting pipe 26 communicates with the second interface and does not protrude from the top pipe section 251 in the height direction.

[0183] Specifically, the compressor 2, the valve island assembly 5, and the pipeline connected to the valve island assembly 5 are suitable for circulating refrigerant. The compressor 2 is suitable for providing power for the circulation of refrigerant in the whole system. It is suitable for drawing in low-temperature and low-pressure gaseous refrigerant through the return gas port, compressing it into high-temperature and high-pressure gaseous refrigerant, and then discharging it through the exhaust port.

[0184] The first interface 54 is connected to the exhaust port of the compressor 2 via a third connecting pipe 25, which has a top pipe section 251. The second interface is connected to other structures outside the valve island assembly 5 via a fourth connecting pipe 26, or the second interface is connected to other connection ports of the valve island assembly 5 via a fourth connecting pipe 26. The fourth connecting pipe 26 does not protrude beyond the top pipe section 251 in the height direction, so that in the pipeline integrated in the valve island assembly 5, at least one pipeline does not protrude beyond the top pipe section 251 of the third connecting pipe 25 in the height direction, that is, the fourth connecting pipe 26 does not protrude beyond the top pipe section 251 of the third connecting pipe 25 in the height direction.

[0185] In such Figure 9 , Figures 11-14 In the illustrated embodiment, the valve island assembly 5 is disposed on one side of the compressor 2 in the height direction, and the top pipe section 251 is located on the side of the valve island assembly 5 away from the compressor 2 in the height direction. The fourth connecting pipe 26 can be designed so that it does not protrude beyond the top pipe section 251 in the height direction, as can be referred to... Figures 1-2 For ease of description and understanding of the scheme, the valve island assembly can be used as a boundary, with the compressor 2 located on the first side 201 of the valve island assembly in the height direction, and the top pipe section 251 located on the second side 202 of the valve island assembly in the height direction.

[0186] At this time, at least a portion of the fourth connecting pipe 26 in the height direction can extend toward the compressor 2, that is, at least a portion of the fourth connecting pipe 26 extends toward the first side 201, so that the placement space of the fourth connecting pipe 26 and the compressor 2 in the height direction overlaps, reducing the space occupied by the fourth connecting pipe 26 on the second side 202; or, at least a portion of the fourth connecting pipe 26 in the height direction extends toward the top pipe section 251 and does not protrude from the top pipe section 251 in the height direction, that is, at least a portion of the fourth connecting pipe 26 extends toward the second side 202 and is located between the top pipe section 251 and the valve island assembly, so that the placement space of the fourth connecting pipe 26 and the top pipe section 251 in the height direction overlaps, reducing the space occupied by the fourth connecting pipe 26 on the second side 202.

[0187] This allows the fourth connecting pipe 26 to overlap with the placement space of other structures in the height direction, eliminating the need for additional space for the fourth connecting pipe 26 in the height direction. This reduces the space required for the fourth connecting pipe 26 in the height direction, improves the integration of the air conditioner 100, reduces the space occupied by the air conditioner 100, and prevents the fourth connecting pipe 26 from interfering with the arrangement of other structures. By limiting the placement positions of the third connecting pipe 25 and the fourth connecting pipe 26, the piping layout of the air conditioner 100 can be optimized, facilitating the production, installation, and maintenance of the air conditioner 100. This is beneficial for achieving miniaturization and weight reduction of products equipped with the air conditioner 100.

[0188] Of course, the second interface can be constructed as one or more, and each fourth connecting pipe 26 connected to the corresponding second interface satisfies the setting of not protruding from the top pipe segment 251 of the third connecting pipe 25 in the height direction.

[0189] Meanwhile, the connection port may also include interfaces such as a third interface. The pipes connected to these interfaces may be arranged so that they do not protrude from the top pipe section 251 in the height direction, or they may all protrude from the top pipe section 251 in the height direction, or a portion of the pipes may not protrude from the top pipe section 251 in the height direction, while another portion of the pipes may protrude from the top pipe section 251 in the height direction. Preferably, the pipes connected to the third interface and other interfaces are arranged so that they do not protrude from the top pipe section 251 in the height direction. In this case, the multiple pipes connected to the valve island assembly 5 do not protrude from the top pipe section 251 of the third connecting pipe 25 in the height direction, so that the air conditioner 100 has a higher degree of integration and occupies less space. Furthermore, by reducing the length of the pipes connected to the valve island assembly 5, the cost of the pipes installed in the air conditioner 100 can also be reduced.

[0190] According to some embodiments of this utility model, such as Figures 1-2 As shown, the valve island assembly 5 includes a valve island body 51 and a valve body. A fluid channel is formed inside the valve island body 51. The valve body is configured as multiple valve bodies and is disposed on the valve island body 51. The valve body is provided with a connection port communicating with the fluid channel. One of the valve bodies is provided with a first interface 54. The second interface is configured as at least one. At least one of the valve island body 51 and the valve body is provided with a second interface.

[0191] Specifically, the valve island body 51 has the aforementioned fluid channels formed inside. Multiple valve bodies are disposed within the valve island body 51, and these valve bodies can be of various types. One or more valve bodies of different types can be provided as needed. In some embodiments, the valve body is a reversing valve 43. The reversing valve 43 determines the flow direction of the refrigerant in the valve island assembly 5, thereby controlling the air conditioner 100 equipped with the valve island assembly 5 for cooling or heating. The reversing valve 43 enables mode switching, function selection, and system control of the air conditioner 100, thereby enhancing the flexibility and functionality of the entire air conditioner 100.

[0192] Each valve body is connected to a fluid passage, and one of the valve bodies is provided with a first interface 54 to connect to the exhaust port of the compressor 2 via a third connecting pipe 25, thereby connecting to the high-temperature, high-pressure gaseous refrigerant compressed by the compressor 2. The second interface is constructed in at least one way; at least one of the valve island body 51 and the valve body is provided with a second interface. This can mean that the second interface is constructed as one and located on either the valve island body 51 or the valve body, or it can mean that there are multiple second interfaces, some of which can be located on the valve island body 51 and others on the valve body, or all of the multiple second interfaces can be located on either the valve island body 51 or the valve body. Each fourth connecting pipe 26 connected to the corresponding second interface is designed so that it does not protrude beyond the top pipe section 251 of the third connecting pipe 25 in the height direction, thereby reducing the space required for the fourth connecting pipe 26 in the height direction, improving the integration of the air conditioner 100, and reducing the space occupied by the air conditioner 100.

[0193] Furthermore, according to some embodiments of the present invention, such as Figures 1-2 As shown, the valve island body 51 has a first side 201 and a second side 202 in the height direction. The first side 201 is provided with a compressor 2, and the second side 202 is provided with a top pipe section 251. At least one valve body is provided on the first side 201 or the second side 202 and does not protrude from the top pipe section 251 in the height direction.

[0194] As mentioned above, with the valve island body 51 as the boundary, the compressor 2 is located on the first side 201 of the valve island body 51 in the height direction, the top pipe section 251 is located on the second side 202 of the valve island body 51 in the height direction, and the valve body is provided on the valve island body 51 and is constructed in multiple ways. Optionally, multiple valve bodies are provided on the first side 201 and / or the second side 202. Of course, the valve body can also be provided between the first side 201 and the second side 202.

[0195] The valve body is such that at least one valve body does not protrude from the top pipe section 251 in the height direction, such that among the valve bodies integrated in the valve island assembly 5, at least one valve body does not protrude from the top pipe section 251 in the height direction.

[0196] At this time, at least a portion of the valve body in the height direction can extend toward the compressor 2, that is, at least a portion of the valve body extends toward the first side 201, so that the placement space of the valve body and the compressor 2 in the height direction overlaps, reducing the space occupied by the valve body on the second side 202.

[0197] Alternatively, at least a portion of the valve body extends toward the top pipe section 251 in the height direction and does not protrude beyond the top pipe section 251 in the height direction. That is, at least a portion of the valve body extends toward the second side 202 and is located between the top pipe section 251 and the valve island body 51, so that the placement space of the valve body and the top pipe section 251 overlaps in the height direction, reducing the space occupied by the valve body on the second side 202.

[0198] Alternatively, the valve body can be positioned between the first side 201 and the second side 202, with its extension direction orthogonal to the height direction, so that the placement space of the valve body and the valve island body 51 overlaps in the height direction, thereby reducing the space occupied by the valve body in the height direction.

[0199] The specific location of the valve body can be designed according to actual needs, as long as at least one valve body does not protrude from the top pipe section 251 in the height direction. The specific location of the valve body is not limited here.

[0200] According to some embodiments of this utility model, such as Figures 1-2 As shown, the reversing valve 43 is located on the second side 202 of the valve island body 51, and a first interface 54 is provided on both sides in the height direction. The first interface 54 is located on the side of the reversing valve 43 away from the valve island body 51, and the connection port of the reversing valve 43 to the fluid channel is located on the side of the reversing valve 43 facing the valve island body 51.

[0201] You can refer to this. Figure 1 and Figure 14 The first interface 54 is located at the top of the reversing valve 43, and the connection port between the reversing valve 43 and the fluid passage is located at the bottom of the reversing valve 43. The refrigerant discharged from the exhaust port of the compressor 2 can flow through the third connecting pipe 25 and into the reversing valve 43 through the first interface 54. Since the first interface 54 is located at the top of the reversing valve 43 in the height direction, and the connection port between the reversing valve 43 and the fluid passage is located at the bottom of the reversing valve 43 in the height direction, the refrigerant can flow from the first interface 54 to the connection port between the reversing valve 43 and the fluid passage under the action of gravity, thereby flowing into the fluid passage. This can accelerate the flow speed of the refrigerant, thereby accelerating the working efficiency of the valve island assembly 5, and thus accelerating the working efficiency of the air conditioner 100.

[0202] Meanwhile, since the first interface 54 is located at the top of the reversing valve 43, the top pipe section 251 of the third connecting pipe 25 can be set at a higher position, and other pipes connected to the valve island assembly 5 can be set below the top pipe section 251 to improve the integration of the air conditioner 100, reduce the space occupied by the air conditioner 100, facilitate production, installation and maintenance, and help to achieve miniaturization and weight reduction of the structure in which the air conditioner 100 is installed.

[0203] In some embodiments, such as Figures 9-14As shown, the functional component 30 includes a compressor 2, which has an exhaust port. The air conditioner 100 includes a reversing valve 43, an expansion valve 44, and a third connecting pipe 25. The reversing valve 43 has at least one first interface 54 at its top and at least one third interface 55 at its bottom, and the at least one third interface 55 is connected to a fluid passage. The third connecting pipe 25 is connected to the exhaust port and the first interface 54, and the third connecting pipe 25 has a top pipe section 251. The expansion valve 44 does not protrude from the top pipe section 251 in the height direction.

[0204] Specifically, the first interface 54 is connected to the exhaust port of the compressor 2 via a third connecting pipe 25, which has a top pipe section 251. The reversing valve 43 is located on the second side 202 of the valve island assembly 5, and has a first interface 54 and a third interface 55 on both sides in the height direction, respectively. The first interface 54 is located on the side of the reversing valve 43 away from the valve island assembly 5, and the third interface 55 is located on the side of the reversing valve 43 facing the valve island assembly 5.

[0205] In such Figures 9-14 In the illustrated embodiment, the valve island assembly 5 is disposed on one side of the compressor 2 in the height direction, and the top pipe section 251 is located on the side of the valve island assembly 5 away from the compressor 2 in the height direction. The fourth connecting pipe 26 can be designed so that it does not protrude beyond the top pipe section 251 in the height direction, as can be referred to... Figures 11-13 For ease of description and understanding of the scheme, the valve island assembly 5 can be used as the boundary, with the compressor 2 located on the first side 201 of the valve island assembly 5 in the height direction, and the top pipe section 251 located on the second side 202 of the valve island assembly 5 in the height direction.

[0206] You can refer to this. Figures 11-13 The first interface 54 is located at the top of the reversing valve 43, and the third interface 55 is located at the bottom of the reversing valve 43. The refrigerant discharged from the compressor 2 exhaust port can flow through the third connecting pipe 25 and into the reversing valve 43 through the first interface 54. Since the first interface 54 is located at the top of the reversing valve 43 in the height direction, and the third interface 55 is located at the bottom of the reversing valve 43 in the height direction, the refrigerant can flow from the first interface 54 to the third interface 55 under the action of gravity, thus flowing into the fluid channel. This can accelerate the flow speed of the refrigerant, thereby increasing the working efficiency of the valve island assembly 5 and thus increasing the working efficiency of the air conditioner 100. At the same time, since the first interface 54 is located at the top of the reversing valve 43, the top pipe section 251 of the third connecting pipe 25 can be set at a higher position. Other pipes connected to the valve island assembly 5 can be set below the top pipe section 251, thereby improving the integration of the air conditioner 100, reducing the space occupied by the air conditioner 100, facilitating production, installation and maintenance, and contributing to the miniaturization and weight reduction of the structure in which the air conditioner 100 is installed.

[0207] The expansion valve 44 does not protrude from the top pipe section 251 in the height direction, so that the placement space of the expansion valve 44 and the top pipe section 251 overlaps in the height direction. There is no need to leave extra placement space for the expansion valve 44 in the height direction, which can reduce the space required for the expansion valve 44 in the height direction, improve the integration of the air conditioner 100, and reduce the space occupied by the air conditioner 100.

[0208] Furthermore, the distance between the expansion valve 44 and the valve island assembly 5 in the height direction is less than the distance between the top pipe section 251 and the valve island assembly 5 in the height direction. At this time, the expansion valve 44 is not protruding from the top pipe section 251 in the height direction, which can reduce the space required for the expansion valve 44 in the height direction, improve the integration of the air conditioner 100, and reduce the space occupied by the air conditioner 100.

[0209] Furthermore, in such Figures 11-13 In the embodiment shown, the expansion valve 44 is adapted to control the opening of the fluid passage, and the distance between the top surface of the expansion valve 44 and the valve island assembly 5 in the height direction is less than or equal to 540 mm.

[0210] Here, the distance between the top surface of the expansion valve 44 and the valve island assembly 5 in the height direction means that after the expansion valve 44 is connected to the corresponding interface of the valve island assembly 5, the distance between the interface end face of the corresponding interface of the valve island assembly 5 and the top surface of the expansion valve 44 in the height direction is no more than 540mm. This is to avoid the expansion valve 44 occupying too much space in the height direction. The expansion valve 44 can be limited to the height range of the top pipe section 251 without protruding, so that the placement space of the expansion valve 44 and the top pipe section 251 overlaps in the height direction, reducing the space occupied by the expansion valve 44 on the second side 202, improving the integration of the air conditioner 100, and reducing the space occupied by the air conditioner 100.

[0211] According to some embodiments of this utility model, such as Figure 4 As shown, the air conditioner 100 also includes a second connecting pipe 24, which is adapted to connect the expansion valve 44 and the valve island assembly 5. The dimension of the second connecting pipe 24 in the height direction is less than or equal to 450 mm.

[0212] Here, the expansion valve 44 and the valve island assembly 5 are connected by a second connecting pipe 24. The two ends of the second connecting pipe 24 are respectively connected to the expansion valve 44 and the valve island assembly 5. One end of the second connecting pipe 24 can be inserted into the corresponding interface of the expansion valve 44, and the other end of the second connecting pipe 24 can be inserted into the corresponding interface of the valve island assembly 5.

[0213] The dimension of the second connecting pipe 24 in the height direction refers to the situation where the axis of the second connecting pipe 24 is perpendicular to both the interface end face of the second connecting pipe 24 and the interface end face of the second connecting pipe 24 and the valve island assembly 5. Figure 12 As shown, the extension direction of the second connecting pipe 24 is consistent with the height direction. The distance between the two interface end faces in the height direction is no more than 450mm. This is to further avoid the expansion valve 44 occupying too much space in the height direction. The expansion valve 44 can be limited to the height range of the top pipe section 251 without protruding. This allows the expansion valve 44 and the top pipe section 251 to overlap in the height direction, reducing the space occupied by the expansion valve 44 on the second side 202, improving the integration of the air conditioner 100, and reducing the space occupied by the air conditioner 100.

[0214] According to some embodiments of this utility model, such as Figures 11-14 As shown, the top pipe section 251 and the valve island assembly 5 are spaced apart in the height direction to define an arrangement space between the top pipe section 251 and the valve island assembly 5, and the expansion valve 44 is configured as at least one and is disposed in the arrangement space.

[0215] Here, the arrangement space defined between the top pipe section 251 and the valve island assembly 5 overlaps with the placement space of the top pipe section 251 in the height direction. The expansion valve 44 is placed in the arrangement space so that the placement space of the expansion valve 44 overlaps with the placement space of the top pipe section 251 in the height direction. There is no need to reserve additional placement space for the expansion valve 44 in the height direction. This can reduce the space required for the expansion valve 44 in the height direction, improve the integration of the air conditioner 100, and reduce the space occupied by the air conditioner 100.

[0216] According to some embodiments of this utility model, such as Figures 9-14 As shown, the reversing valve 43 extends in a direction that intersects with its height. Multiple third ports 55 are spaced apart along the extension direction of the reversing valve 43. At least two third ports 55 can be selectively connected, or the first port 54 can be selectively connected to at least one third port 55. Specifically, the reversing valve 43 has multiple third ports 55. By selectively connecting at least two third ports 55 or selectively connecting the first port 54 to at least one third port 55, the flow direction of the refrigerant in the valve island assembly 5 can be changed, thereby controlling the cooling or heating function of the air conditioner 100.

[0217] According to some embodiments of this utility model, such as Figures 9-14 As shown, the third connecting pipe 25 is used to connect the valve island assembly 5 with the external structure of the valve island assembly 5. The air conditioner 100 also includes a first connecting pipe 23, which is adapted to connect the third interface 55 of the reversing valve 43 with the fluid passage. The first connecting pipe 23 does not protrude from the top pipe section 251 in the height direction.

[0218] In other words, the first connecting pipe 23 is used to connect the reversing valve 43 and the valve island assembly 5, and the first connecting pipe 23 and the third interface 55 are set one-to-one. By designing the first connecting pipe 23 not to protrude from the top pipe section 251 in the height direction, at least one pipe in the valve island assembly 5 itself does not protrude from the top pipe section 251 in the height direction, so that the placement space of the first connecting pipe 23 and the top pipe section 251 overlaps in the height direction, reducing the space occupied by the first connecting pipe 23 on the second side 202, improving the integration of the air conditioner 100, and reducing the space occupied by the air conditioner 100.

[0219] Furthermore, the first connecting pipe 23 has a height dimension of less than or equal to 420 mm. Here, the directional valve 43 and the valve island assembly 5 are connected by the first connecting pipe 23. Both ends of the first connecting pipe 23 are connected to the directional valve 43 and the valve island assembly 5, respectively. One end of the first connecting pipe 23 can be inserted into the corresponding port of the directional valve 43, and the other end of the first connecting pipe 23 can be inserted into the corresponding port of the valve island assembly 5.

[0220] The dimension of the first connecting pipe 23 in the height direction refers to the situation where the axis of the first connecting pipe 23 is perpendicular to both the interface end face of the first connecting pipe 23 and the reversing valve 43 and the interface end face of the first connecting pipe 23 and the valve island assembly 5. Figure 12 As shown, the extension direction of the first connecting pipe 23 is consistent with the height direction. If the angle between the axis of the first connecting pipe 23 and any of the interface end faces is not equal to 90°, the extension direction of the first connecting pipe 23 intersects with the height direction. At this time, the distance between the two interface end faces may be greater than 420mm, and the distance between the two interface end faces in the height direction is the dimension of the first connecting pipe 23 in the height direction.

[0221] To ensure that the dimension of the first connecting pipe 23 in the height direction is no greater than 420mm, so as to avoid the first connecting pipe 23 and the reversing valve 43 occupying too much space in the height direction, the first connecting pipe 23 and the reversing valve 43 can be limited to the height range of the top pipe section 251 without protruding in the height direction. This allows the first connecting pipe 23 and the reversing valve 43 to overlap with the placement space of the top pipe section 251 in the height direction, reducing the space occupied by the first connecting pipe 23 and the reversing valve 43 on the second side 202, improving the integration of the air conditioner 100, and reducing the space occupied by the air conditioner 100.

[0222] In some embodiments, both the second connecting pipe 24 and the first connecting pipe 23 can be made of stainless steel, and the stainless steel pipe can be directly inserted into the corresponding interface of the valve island assembly 5. In other embodiments, a copper sleeve can be fitted at the connection between the stainless steel pipe and the corresponding interface, and the copper sleeve can be welded to the stainless steel pipe. In this case, the size of the copper sleeve is also a part of the size of the stainless steel pipe.

[0223] When measuring the dimensions of stainless steel pipes, the following reference standards can be used: The distance in the height direction between the interface end face of the second connecting pipe 24 and the expansion valve 44 and the interface end face of the second connecting pipe 24 and the valve island assembly 5 is the dimension of the second connecting pipe 24 in the height direction. The dimension of the second connecting pipe 24 in the height direction can be measured with the above two interface end faces as a reference.

[0224] The distance in the height direction between the interface end face of the first connecting pipe 23 and the reversing valve 43 and the interface end face of the first connecting pipe 23 and the valve island assembly 5 is the dimension of the first connecting pipe 23 in the height direction. The dimension of the first connecting pipe 23 in the height direction can be measured with the above two interface end faces as a reference.

[0225] In some embodiments, such as Figure 9 , Figures 11-14 As shown, the third connecting pipe 25 has a clearance structure 252 defined on it. While the third connecting pipe 25 is connected to the exhaust port and the first interface 54, it can provide sufficient installation space for other components inside the air conditioner 100, making the internal layout of the housing 1 more reasonable.

[0226] Meanwhile, the third connecting pipe 25 is separated from other components inside the air conditioner 100. When the air conditioner 100 is working, the compressor 2 vibrates, which drives the third connecting pipe 25 to vibrate. There is no direct connection between the third connecting pipe 25 and other components inside the air conditioner 100, so as to avoid vibration of other components inside the air conditioner 100 caused by the vibration of the third connecting pipe 25, and to avoid damage to other components inside the air conditioner 100 due to vibration.

[0227] In some embodiments of this utility model, the air conditioner 100 further includes an electronic control component, which is installed in the housing 1. The electronic control component can receive instructions from components such as the control panel and can collect temperature data from the sensor to adjust the working state of the air conditioner 100.

[0228] A reversing valve 43 is located above the compressor 2. The reversing valve 43 is connected to the exhaust port of the compressor 2 via a third connecting pipe 25. The upper end of the third connecting pipe 25 defines a clearance structure 252 to avoid the electronic control components. While the third connecting pipe 25 connects the reversing valve 43 and the exhaust port of the compressor 2, it also provides sufficient installation space for the electronic control components, making the internal structure layout of the air conditioner 100 more reasonable.

[0229] Meanwhile, the third connecting pipe 25 is spaced apart from the electronic control component. When the air conditioner 100 is working, the compressor 2 vibrates, which drives the third connecting pipe 25 to vibrate. There is no direct connection between the third connecting pipe 25 and the electronic control component, so as to avoid the vibration of the electronic control component caused by the vibration of the third connecting pipe 25, and to avoid damage to the precision circuit inside the electronic control component due to vibration.

[0230] In some embodiments of this utility model, such as Figure 9 and Figure 14 As shown, a partition 12 is provided inside the housing 1. The partition 12 is used to divide the housing 1 into a compressor chamber 11 and a fan chamber 13 that are spaced apart in the horizontal direction. The partition 12 can be connected to the housing 1 by means of connectors or welding. The connectors can be bolts, etc. The structure is simple, the installation is convenient, and the installation cost is low.

[0231] A fan assembly can be installed inside the fan cavity 13. The fan assembly includes a drive motor, fan blades, and a heat exchanger. The drive motor can drive the fan blades to rotate, and the fan blades can dissipate heat and cool the heat exchanger when they rotate, so as to ensure the stability of the heat exchanger operation.

[0232] The compressor assembly is installed inside the compressor chamber 11. Thus, the fan chamber and the compressor chamber 11 can be separated by a partition 12. When the drive motor, fan blades and compressor 2 are running, the partition 12 can block the vibration between the fan chamber and the compressor chamber 11, so as to avoid interference between the structure inside the fan chamber and the structure inside the compressor chamber 11, and ensure the reliability of the air conditioner 100.

[0233] The electronic control component is located inside the compressor cavity 11. The electronic control component can be installed on the front side plate of the housing 1, or on the side plate of the housing 1, or on the partition plate 12 of the housing 1.

[0234] In this embodiment, the electronic control component is located inside the compressor cavity 11 and connected to the partition plate 12. The upper end of the third connecting pipe 25 facing the fan cavity 13 defines a clearance structure 252 to avoid the electronic control component. While the third connecting pipe 25 connects the reversing valve 43 and the exhaust port of the compressor 2, it can provide sufficient installation space for the electronic control component, making the layout of the compressor cavity 11 more reasonable.

[0235] In some embodiments of this utility model, such as Figure 12 and Figure 13As shown, the third connecting pipe 25 includes a first sub-pipe 253 and a second sub-pipe 254. The first sub-pipe 253 is connected to the top pipe section 251 and extends vertically. One end of the second sub-pipe 254 is connected to the lower end of the first sub-pipe 253 along its length, and the other end extends away from the first sub-pipe 253 to form a clearance space. It can be understood that the connection of one end of the second sub-pipe 254 to the lower end of the first sub-pipe 253 and the extension of the other end toward the fan cavity 13 makes the third connecting pipe 25 extend toward the fan cavity 13. The third connecting pipe 25 connects the reversing valve 43 and the compressor 2. Along the direction from the reversing valve 43 to the second sub-pipe 254, the portion of the third connecting pipe 25 located downstream of the second sub-pipe 254 can provide space for the arrangement of other pipes. The first sub-tube 253 and the second sub-tube 254 together form the avoidance structure 252. The first sub-tube 253 and the second sub-tube 254 can provide sufficient installation space for the electronic control components, making the layout of the compressor cavity 11 more reasonable.

[0236] In this embodiment, the second sub-pipe 254 can avoid the reversing valve 43, increasing the rationality of the layout of the compressor cavity 11.

[0237] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the two ends of the second sub-pipe 254 along its length are the first end and the second end, respectively. The first end is connected to the lower end of the first sub-pipe 253. The direction from the first end to the second end is the first direction, which forms an angle with both the horizontal and vertical directions. The second sub-pipe 254, while forming the avoidance structure 252, can reduce the total length of the third connecting pipe 25, increasing the refrigerant flow rate. Simultaneously, the refrigerant flow within the third connecting pipe 25 is smoother than with a right-angle bend, avoiding any impact on refrigerant flow.

[0238] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the angle between the first direction and the horizontal direction is A, and satisfies: 10° ≤ A < 90°. It can be understood that the angle between the first direction and the horizontal direction can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, or 90°. An angle between the first direction and the horizontal direction of not less than 10° and less than 90° avoids the angle between the second sub-pipe 254 and the vertically arranged first sub-pipe 253 approaching a right angle. This ensures smoother refrigerant flow within the first sub-pipe 253 and the second sub-pipe 254 compared to a right-angle bend, preventing disruption to refrigerant flow.

[0239] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, a first arc-shaped connecting portion 255 is provided between the first sub-pipe 253 and the second sub-pipe 254, making the connection between the first sub-pipe 253 and the second sub-pipe 254 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. Simultaneously, it increases the elasticity of the third connecting pipe 25, reducing the risk of damage to the third connecting pipe 25 due to vibration and other issues.

[0240] In some embodiments of this utility model, the radius of the arc of the first arc connecting portion 255 is R1, and satisfies: 15mm ≤ R1 ≤ 25mm. It can be understood that the radius of the arc of the first arc connecting portion 255 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. A radius of arc of no more than 15mm avoids a rapid transition between the first sub-pipe 253 and the second sub-pipe 254, preventing obstruction of refrigerant flow. A radius of arc of no more than 25mm avoids a large size for the first arc connecting portion 255, preventing an increase in the manufacturing material of the third connecting pipe 25 and thus avoiding an increase in the manufacturing cost of the third connecting pipe 25.

[0241] In this embodiment, the radius of the first arc connecting part 255 is the radius of the arc at the axis of the first arc connecting part 255.

[0242] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the third connecting pipe 25 also includes a third sub-pipe 256 and a fourth sub-pipe 257. The third sub-pipe 256 extends vertically and its lower end is connected to the reversing valve 43. It extends horizontally, with one end of the top pipe section 251 connected to the upper end of the third sub-pipe 256 and the other end connected to the upper end of the first sub-pipe 253. This allows the third connecting pipe 25 to be extended horizontally to avoid the area of ​​the reversing valve 43, increasing the rationality of the layout. One end of the fourth sub-pipe 257 is connected to the end of the second sub-pipe 254 that is away from the first sub-pipe 253, and the other end is connected to the exhaust port of the compressor 2.

[0243] It is understandable that the refrigerant discharged from the exhaust pipe of compressor 2 flows from the fourth sub-pipe 257 to the second sub-pipe 254, then to the first sub-pipe 253, and finally through the top pipe section 251 to the third sub-pipe 256, and enters the reversing valve 43. The connection port of the reversing valve 43, which is connected to the third sub-pipe 256, is located at the upper end of the reversing valve 43. The layout of the third connecting pipe 25 is relatively reasonable.

[0244] In some embodiments of this utility model, such as Figure 12 and Figure 13As shown, a second arc-shaped connecting portion 258 is provided between the first sub-pipe 253 and the top pipe section 251, making the connection between the first sub-pipe 253 and the top pipe section 251 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. Simultaneously, it increases the elasticity of the third connecting pipe 25, reducing the risk of damage to the third connecting pipe 25 due to vibration and other issues.

[0245] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, a third arc-shaped connecting portion 259 is provided between the second sub-pipe 254 and the fourth sub-pipe 257, making the connection between the second sub-pipe 254 and the fourth sub-pipe 257 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. Simultaneously, it increases the elasticity of the third connecting pipe 25, reducing the risk of damage to the third connecting pipe 25 due to vibration and other issues.

[0246] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, a fourth arc-shaped connecting part 27 is provided between the third sub-pipe 256 and the top pipe section 251, making the connection between the third sub-pipe 256 and the top pipe section 251 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. At the same time, it increases the elasticity of the third connecting pipe 25, reducing the risk of damage to the third connecting pipe 25 due to vibration and other problems.

[0247] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the radius of the second arc connecting part 258 is R2, and satisfies: 15mm ≤ R2 ≤ 25mm. It can be understood that the radius of the second arc connecting part 258 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. A radius of no more than 15mm for the second arc connecting part 258 avoids a sharp transition between the first sub-pipe 253 and the top pipe section 251, preventing obstruction of refrigerant flow. A radius of no more than 25mm for the second arc connecting part 258 avoids a larger size, preventing an increase in the manufacturing material of the third connecting pipe 25 and thus avoiding an increase in the manufacturing cost of the third connecting pipe 25.

[0248] In this embodiment, the radius of the second arc connecting part 258 is the radius of the arc at the axis of the second arc connecting part 258.

[0249] In some embodiments of this utility model, such as Figure 12 and Figure 13As shown, the radius of the arc of the third arc connecting part 259 is R3, and satisfies: 15mm ≤ R3 ≤ 25mm. It can be understood that the radius of the arc of the third arc connecting part 259 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. A radius of no more than 15mm for the arc of the third arc connecting part 259 avoids a too abrupt transition between the second sub-pipe 254 and the fourth sub-pipe 257, preventing obstruction of refrigerant flow. A radius of no more than 25mm for the arc of the third arc connecting part 259 avoids a larger size, preventing an increase in the manufacturing material of the third connecting pipe 25 and thus avoiding an increase in the manufacturing cost of the third connecting pipe 25.

[0250] In this embodiment, the radius of the arc of the third arc connecting part 259 is the radius of the arc at the axis of the third arc connecting part 259.

[0251] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the radius of the fourth arc connecting part 27 is R4, and satisfies: 15mm ≤ R4 ≤ 25mm. It can be understood that the radius of the fourth arc connecting part 27 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. The radius of the fourth arc connecting part 27 not exceeding 15mm avoids a sharp transition between the third sub-pipe 256 and the top pipe section 251, preventing obstruction of refrigerant flow. The radius of the third arc connecting part 259 not exceeding 25mm avoids a larger size for the third arc connecting part 259, preventing an increase in the manufacturing material of the third connecting pipe 25 and thus avoiding an increase in the manufacturing cost of the third connecting pipe 25.

[0252] In this embodiment, the radius of the fourth arc connecting part 27 is the radius of the arc at the axis of the fourth arc connecting part 27.

[0253] In some embodiments of this utility model, such as Figure 12 and Figure 13As shown, the length of the second sub-pipe 254 in the horizontal direction is L1, and it satisfies: 20mm ≤ L1 ≤ 115mm. It can be understood that the length of the second sub-pipe 254 in the horizontal direction can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, or 115mm. The length of the second sub-pipe 254 is not less than 20mm, allowing it to maintain a horizontal distance from the reversing valve 43, thus enabling the avoidance structure 252 to avoid interference with other structures in the horizontal direction. The length of the second sub-pipe 254 is not more than 115mm, preventing interference between the second sub-pipe 254 and other components in the horizontal direction, thus increasing the rationality of the internal spatial layout of the air conditioner 100.

[0254] The length of the second sub-tube 254 is measured based on the length between the end point near the second arc connecting part 258 and the end point near the third arc connecting part 259.

[0255] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, in the vertical direction, the length of the first sub-pipe 253 is L2, and the length of the third sub-pipe 256 is L3, satisfying: -15mm ≤ L2 - L3 ≤ 15mm. It can be understood that the length difference between the first sub-pipe 253 and the third sub-pipe 256 in the vertical direction can be -15mm, -10mm, -5mm, 0mm, 5mm, 10mm, or 15mm. The lengths of the first sub-pipe 253 and the third sub-pipe 256 can be designed according to the internal layout of the air conditioner 100 to meet different design requirements and avoid interference between components inside the air conditioner 100.

[0256] The length of the first sub-tube 253 is measured based on the length between the end near the second arc connection 258 and the end near the second arc connection 258. The length of the third sub-tube 256 is measured based on the length between the end near the fourth arc connection 27 and the end near the reversing valve 43.

[0257] In some embodiments, such as Figures 16-19 As shown, the air conditioner 100 also includes a plate heat exchanger 41 and an expansion valve 44. There are multiple expansion valves 44, including a first expansion valve 441. The plate heat exchanger 41 is disposed inside the housing 1 and is located on the periphery of the valve island assembly 5. The first expansion valve 441 is connected to a fluid channel. The fluid channel is connected to the plate heat exchanger 41 through an expansion valve connecting pipe 443. The length of the expansion valve connecting pipe 443 is greater than or equal to 118 mm or less than or equal to 600 mm.

[0258] Specifically, a first expansion valve 441 is disposed on the valve island assembly 5. A fluid passage is connected to the first expansion valve 441, and the fluid passage extends an interface along the upper end face, lower end face, or side face of the valve island assembly 5. This interface is used to connect to one end of the expansion valve connecting pipe 443. The plate heat exchanger 41 has a plate heat exchanger interface for connecting to the expansion valve connecting pipe 443 located at the end of the length of the plate heat exchanger 41. The other end of the expansion valve connecting pipe 443 is connected to the plate heat exchanger interface located at the end of the length of the plate heat exchanger 41, thus connecting the plate heat exchanger 41 with the expansion valve. The pipe length between valve connecting pipes 443 is greater than or equal to 118mm, such as 120mm or 125mm, which makes the distance between plate heat exchanger 41 and first expansion valve 441 more reasonable, and the size of plate heat exchanger 41 itself can be set more reasonably. The refrigerant has a longer flow path in plate heat exchanger 41, and the heat exchange is more complete. The gap between valve island assembly 5 and partition plate 12 can be fully utilized to arrange plate heat exchanger 41 with more reasonable size.

[0259] Of course, the length of the expansion valve connecting pipe 443 in this embodiment can also be less than or equal to 600mm, which can make the length of the expansion valve connecting pipe 443 more reasonable, reduce the number of bends, thereby reducing the flow resistance of the refrigerant, improving pressure drop and pressure loss, reducing energy consumption, improving the temperature regulation capability of the air conditioner, and avoiding the expansion valve connecting pipe 443 being too long, so as to take into account space occupation. Moreover, the expansion valve connecting pipe 443 with a more reasonable length is easier to avoid surrounding components during the installation process, and can also reduce the difficulty of layout.

[0260] It should be noted that, in this application embodiment, the length of the expansion valve connecting pipe 443 can be greater than or equal to 118mm, which is one technical solution, while the length of the expansion valve connecting pipe 443 is less than or equal to 600mm, which is another technical solution. The two are not continuously limited by upper and lower limits for the expansion valve connecting pipe 443. That is, there is no upper limit to the range of the expansion valve connecting pipe 443 being greater than or equal to 118mm, and there is no lower limit to the range being less than or equal to 600mm. When the length of the expansion valve connecting pipe 443 is in the range of 118mm-600mm, the technical effect of both can be achieved, which is the preferred embodiment.

[0261] Combination Figure 16 As shown, according to some embodiments of the present invention, a fixing member is provided inside the shell 1, and the plate heat exchanger 41 is disposed on the fixing member.

[0262] The fastener can be the outer shell of other components inside the housing 1, such as the gas-liquid separator 3, or a fixed structure inside the housing, such as a bracket or support plate.

[0263] It is understandable that by fixing the plate heat exchanger 41 with fasteners, the space inside the shell 1 can be made more fully and the space occupied can be improved.

[0264] According to some embodiments of this application, the fastener can be configured as a partition 12, and the plate heat exchanger 41 is disposed on the side of the partition 12 facing the valve island assembly 5. The partition 12 can divide the accommodating space of the housing 1 into a fan chamber 13 and a compressor chamber 11. The plate heat exchanger 41 is disposed on the partition 12, and the projection of the plate heat exchanger 41 toward the partition 12 at least partially overlaps with the projection of the valve island assembly 5 toward the partition 12.

[0265] Specifically, one end of the partition 12 is connected to the bottom plate 15 of the housing 1, and the other end of the housing 1 is connected to the top cover 14 of the housing 1, so as to divide the fan chamber 13 and the compressor chamber 11 within the accommodating space of the housing 1. The plate heat exchanger 41 can be installed on the partition 12, and the mounting position of the plate heat exchanger 41 is set on the partition 12, eliminating the need for a separate mounting structure for the plate heat exchanger 41, which can reduce costs. Furthermore, the projection of the plate heat exchanger 41 and the first expansion valve 441 toward the partition at least partially overlaps, so that at least part of the plate heat exchanger 41 is located in the gap between the first expansion valve 441 and the partition 12, which can make fuller use of the compression. The machine cavity 11 provides space, and the portion of the plate heat exchanger 41 located within the projection outline of the first expansion valve 441 is closest to the first expansion valve 441. At least a portion of the plate heat exchanger interfaces on the plate heat exchanger 41 can be correspondingly set within the projection outline, and a straight outlet pipe can be achieved. This not only further reduces the length of the high-pressure valve connecting pipe 461, the expansion valve connecting pipe 443 (and other connecting pipes led out from the plate heat exchanger 41), but also allows one of the high-pressure valve connecting pipe or the expansion valve connecting pipe 443 to be constructed as a straight outlet pipe, which can be directly connected to the high-pressure valve 46 or the first expansion valve 441 after a single bend. The pipe resistance of the straight outlet pipe is lower.

[0266] According to some embodiments of the present invention, the first expansion valve 441 and the high-pressure valve 46 are both located on the side of the valve island assembly 5 adjacent to the plate heat exchanger 41.

[0267] There can be multiple expansion valves 44, such as the main expansion valve in the main circuit and the enthalpy-increasing expansion valve in the enthalpy-increasing branch circuit. The first expansion valve 441 is an enthalpy-increasing expansion valve, which makes the valve island assembly 5 close to the plate heat exchanger 41. This makes the distance between the valve island assembly 5 and the plate heat exchanger 41 closer, and the length of the high-pressure valve connecting pipe 461 between the high-pressure valve 46 and the plate heat exchanger 41 can be set more reasonably without having to cross too many pipes or components.

[0268] It should be noted that the plate heat exchanger 41 has a main inlet and a main outlet, an enthalpy-increasing inlet and an enthalpy-increasing outlet. The fluid channel where the high-pressure valve 46 is located is connected to the main inlet of the plate heat exchanger 41. The first expansion valve 441 and the filter are connected. The fluid channel where the filter is located is connected to the main outlet and to the refrigerant heat dissipation pipe. The other end of the refrigerant heat dissipation pipe is connected to the valve island assembly 5, which integrates the low-pressure valve 47. The valve island assembly 5 is connected to the low-pressure valve 47, the main expansion valve (i.e., the second expansion valve 442), and the reversing valve 43. The reversing valve 43 is also connected to the gas-liquid separator 3. The first expansion valve 441 is connected to the enthalpy-increasing inlet. The enthalpy-increasing outlet is connected to the enthalpy-increasing pipe. The enthalpy-increasing pipe is connected to the compressor enthalpy-increasing port to define the complete main refrigerant flow path and the enthalpy-increasing branch refrigerant flow path.

[0269] It is understandable that the first expansion valve 441 and the high-pressure valve 46 are both located on the side of the valve island assembly 5 adjacent to the plate heat exchanger 41, which makes the distance between the high-pressure valve connecting pipe 461 and the main inlet of the plate heat exchanger 41 closer, and the main inlet and the enthalpy-increasing outlet are located at the same end of the plate heat exchanger 41 along its own length direction, which can effectively reduce the length of the high-pressure valve connecting pipe 461 and the expansion valve connecting pipe 443.

[0270] Combination Figures 16-19 As shown, according to some embodiments of the present invention, the projected profile of the expansion valve connecting pipe 443 facing the vertical plane has a dimension greater than or equal to 78mm in the vertical direction.

[0271] Specifically, one end of the expansion valve connecting pipe 443 is connected to the first expansion valve 441, and the other end extends toward the plate heat exchanger 41. Based on the installation position of the plate heat exchanger 41, the expansion valve connecting pipe 443 may be constructed to extend at an angle. The projected outline shape of the expansion valve connecting pipe 443 toward the vertical plane may be inclined relative to the vertical direction. This utility model limits the dimension of the projected outline of the expansion valve connecting pipe 443 toward the vertical plane in the vertical direction. If it is inclined relative to the vertical direction, the dimension in the vertical direction is the dimension obtained by further projecting the projected outline toward the vertical plane toward the vertical direction. In other words, the expansion valve connecting pipe 443 projects toward the vertical plane on the side where the partition plate 12 is located, and the dimension of the projection in the vertical direction is greater than or equal to 78mm.

[0272] It is understood that in this invention, the vertical dimension of the expansion valve connecting pipe 443 is greater than or equal to 78mm, and the plate heat exchanger interface of the plate heat exchanger 41 used to connect the expansion valve connecting pipe 443 is located at the bottom end of the plate heat exchanger 41. The expansion valve connecting pipe 443 extends from bottom to top and extends to the interface area located on the end face or side of the valve island assembly 5. By making the vertical extension dimension of the expansion valve connecting pipe 443 greater than or equal to 78mm, the valve island assembly 5 can be located at least partially above the plate heat exchanger 41. This makes the position of the plate heat exchanger 41 more reasonable, reduces the height dimension of the portion of the plate heat exchanger 41 above the valve island assembly 5, and allows for avoidance of surrounding components, reducing the probability of interference. Such a limitation can be further specified. The height difference between the plate heat exchanger 41 and the first expansion valve 441 makes the height difference between the plate heat exchanger 41 and the first expansion valve 441 more reasonable, so that the setting position of the plate heat exchanger 41 is more reasonable. Sufficient space can be reserved between the plate heat exchanger 41 and the top cover 14, and between the first expansion valve 441 and the top cover 14, effectively reducing the space occupied by the plate heat exchanger 41 and the first expansion valve 441 in the compressor cavity 11. It can also reduce the technical problem of the plate heat exchanger 41 being difficult to install due to the small gap between the first expansion valve 441 and the partition plate 12. At the same time, the height dimension of the plate heat exchanger 41 itself can also be specifically limited, and a more reasonable height plate heat exchanger 41 can be used to ensure the heat exchange effect and heat exchange efficiency of the plate heat exchanger 41.

[0273] Furthermore, the projected profile of the expansion valve connecting pipe 443 toward the vertical plane has a vertical dimension of less than or equal to 450 mm.

[0274] Therefore, the vertical dimension of the expansion valve connecting pipe 443 can be avoided from being too long. On the one hand, the expansion valve connecting pipe 443 can be bent towards the plate heat exchanger interface of the plate heat exchanger 41 to form an obtuse angle between the first pipe section connected to the plate heat exchanger 41 and the second pipe section of the expansion valve connecting pipe 443 extending in a generally vertical direction, so as to reduce the flow resistance of the refrigerant. On the other hand, the vertical dimension of the expansion valve connecting pipe 443 is more reasonable, which can avoid the expansion valve connecting pipe 443 being too long and increasing the space occupation, so as to take into account the needs of compact and integrated layout and effectively reduce the space occupation.

[0275] Combination Figures 16-19 As shown, according to some embodiments of the present invention, the projected profile of the expansion valve connecting pipe 443 toward the horizontal plane has a horizontal dimension greater than or equal to 37mm.

[0276] Specifically, based on the location of the plate heat exchanger 41, the expansion valve connecting pipe 443 may be constructed to extend at an angle. The projected outline of the expansion valve connecting pipe 443 toward the base plate 15 may be inclined relative to the length or width direction of the horizontal plane. This utility model defines the horizontal dimension of the projected outline of the expansion valve connecting pipe 443 toward the base plate 15 as the dimension in the horizontal direction (e.g., if the plate heat exchanger 41 and the first expansion valve 441 are opposite each other in the length direction of the base plate 15, then the horizontal dimension can be the dimension in the length direction of the base plate 15; or if the plate heat exchanger 41 and the first expansion valve 441 are opposite each other in the width direction of the base plate 15, then the horizontal dimension can be the dimension in the width direction of the base plate 15). If the expansion valve connecting pipe 443 is inclined relative to the horizontal direction, then the horizontal dimension is the dimension obtained by further projecting the projected outline of the horizontal plane projected toward one side of the base plate 15 toward the width or length direction of the base plate 15. In other words, the horizontal dimension of the projection of the expansion valve connecting pipe 443 toward the horizontal plane on the side where the base plate 15 is located is greater than or equal to 37mm.

[0277] Furthermore, this utility model makes the horizontal dimension of the expansion valve connecting pipe 443 greater than or equal to 37mm, which can further limit the maximum distance between the plate heat exchanger 41 and the first expansion valve 441 in the horizontal direction, making the maximum distance between the plate heat exchanger 41 and the first expansion valve 441 more reasonable, so that the setting position of the plate heat exchanger 41 is more reasonable, and the size of the plane of the valve island assembly 5 of the first expansion valve 441 is more reasonable. This can make full use of the space inside the compressor cavity and reduce the difficulty of setting the plate heat exchanger 41 and the first expansion valve 441.

[0278] It should be noted that the projected profile of the expansion valve connecting pipe 443 toward the horizontal plane has a horizontal dimension of less than or equal to 280 mm.

[0279] Therefore, the horizontal dimension of the expansion valve connecting pipe 443 can be avoided from being too long. On the one hand, the expansion valve connecting pipe 443 can be bent towards the plate heat exchanger interface of the plate heat exchanger 41 to form an obtuse angle between the first pipe section connected to the plate heat exchanger 41 and the second pipe section of the expansion valve connecting pipe 443 extending in a generally vertical direction, so as to reduce the flow resistance of the refrigerant. On the other hand, the horizontal dimension of the expansion valve connecting pipe 443 is more reasonable, which can avoid the horizontal distance between the plate heat exchanger 41 and the valve island assembly 5 being too large, so as to take into account the requirements of compact and integrated layout and effectively reduce the space occupation.

[0280] In some embodiments, the expansion valve connecting pipe 443 may include a first pipe section extending generally horizontally and a second pipe section extending generally vertically. The total length of the first and second pipe sections is greater than or equal to 118 mm. The vertical dimension of the projection profile of the expansion valve connecting pipe 443 toward the partition 12 is the vertical dimension of the projection profile of the second pipe section, which is greater than or equal to 78 mm and should be less than or equal to 450 mm. This corresponds to the vertical distance between the interface connecting the plate heat exchanger 41 and the first expansion valve 441 and the first expansion valve 441. The straight distance should be greater than or equal to 78mm and less than or equal to 450mm. The horizontal dimension of the projection outline of the expansion valve connecting pipe 443 on the horizontal plane facing the bottom plate 15 should be greater than or equal to 37mm and less than or equal to 280mm. This corresponds to the horizontal distance between the plate heat exchanger 41 and the first expansion valve 441 being greater than or equal to 37mm and less than or equal to 280mm. This can effectively avoid interference between the plate heat exchanger 41, the expansion valve connecting pipe 443 and the surrounding components, and make full use of the gap between the partition plate 12 and the first expansion valve 441.

[0281] It is understood that the vertical distance between the plate heat exchanger interface connecting the plate heat exchanger 41 and the first expansion valve 441 and the first expansion valve 441 should be greater than or equal to 78 mm and less than or equal to 450 mm. The horizontal distance between the plate heat exchanger 41 and the first expansion valve 441 should be greater than or equal to 37 mm and less than or equal to 280 mm. This means that the dimension less than or equal to is a technical solution, while the dimension greater than or equal to is a technical solution. The two are parallel technical solutions that can be selectively implemented by those skilled in the art based on the description of this application, rather than upper and lower limits of the dimension.

[0282] It should be noted that the length of the expansion valve connecting pipe 443 involved in the embodiments of this utility model refers to the distance between the first expansion valve interface on the valve island assembly 5 and the plate heat exchanger interface on the plate heat exchanger 41 used to connect the first expansion valve 441. If the first expansion valve interface is located on the lower end face of the valve island assembly 5, then the length of the expansion valve connecting pipe 443 refers to the distance between the first expansion valve interface on the lower end face of the valve island assembly 5 and the plate heat exchanger interface on the side of the plate heat exchanger 41 facing the first expansion valve 441 used to connect the expansion valve connecting pipe 443. Since the expansion valve connecting pipe 443 can be arranged at an incline and bend, this utility model further defines the vertical and horizontal dimensions of the expansion valve connecting pipe 443. The vertical dimension is the projection dimension of the vertical plane projection dimension in the vertical direction, and the horizontal dimension is the projection dimension of the horizontal plane projection dimension in the horizontal direction.

[0283] According to some embodiments of this utility model, such as Figure 16As shown, the expansion valve 44 also includes a second expansion valve 442, and the gap between the low-pressure valve 47 and the high-pressure valve 46 is adapted to accommodate the second expansion valve 442.

[0284] Specifically, by defining a gap between the low-pressure valve 47 and the high-pressure valve 46, the second expansion valve 442 can be located within the gap, which can further compress the internal structure of the air conditioner 100 and effectively reduce the space occupied by the air conditioner 100.

[0285] In some embodiments, such as Figures 16-19 As shown, the air conditioner 100 also includes a plate heat exchanger 41 and a high-pressure valve 46. The plate heat exchanger 41 is located inside the housing 1. The high-pressure valve 46 is connected to the plate heat exchanger 41 through a high-pressure valve connecting pipe 461, or the high-pressure valve 46 is connected to a fluid passage. The fluid passage is connected to the plate heat exchanger 41 through a high-pressure valve connecting pipe 461. The length of the high-pressure valve connecting pipe 461 is greater than or equal to 110 mm.

[0286] Specifically, such as Figures 16-19 As shown, the high-pressure valve 46 is mounted on the valve island assembly 5 and is connected to the fluid channel. The interface corresponding to the fluid channel is connected to the plate heat exchanger 41 through the high-pressure valve connecting pipe 461.

[0287] The plate heat exchanger 41 has a plate heat exchanger interface for connecting to the high-pressure valve connecting pipe 461 located at one end of the length of the plate heat exchanger 41. The high-pressure valve 46 is located on the valve island assembly 5, which is located at the other end of the length of the plate heat exchanger 41. That is, the high-pressure valve connecting pipe 461 needs to be extended from one end of the length of the plate heat exchanger 41 to the other end of the length of the plate heat exchanger 41 to connect to the interface on the valve island assembly 5 (the interface corresponding to the flow channel connected to the high-pressure valve 46) or directly to the high-pressure valve 46.

[0288] In this design, the plate heat exchanger 41 has a plate heat exchanger interface for connecting to the high-pressure valve connecting pipe 461, located at one end of the plate heat exchanger 41's length. The high-pressure valve 46 is located on the valve island assembly 5, which is located at the other end of the plate heat exchanger 41's length. Therefore, the high-pressure valve connecting pipe 461 needs to extend from one end of the plate heat exchanger 41 to the other end to connect with the interface on the valve island assembly 5 (the interface corresponding to the flow channel connected to the high-pressure valve 46) or directly to the high-pressure valve 46. This ensures that the pipe length of the high-pressure valve connecting pipe 461 is greater than or equal to 110mm, such as 110mm or 120mm. To make the distance between the pipes above the valve island assembly 5 and the plate heat exchanger 41 more reasonable, the size of the plate heat exchanger 41 itself can be set more reasonably, the refrigerant flow path length in the plate heat exchanger 41 is longer, the heat exchange is more complete, the gap between the high pressure valve 46 and the partition 12 can be fully utilized to arrange the plate heat exchanger 41 with more reasonable size, and the length of the high pressure valve connecting pipe 461 can be more reasonable, which can also reduce costs and reduce the number of bends, thereby reducing the refrigerant flow resistance, improving pressure drop and pressure loss, reducing energy consumption, and improving the temperature regulation capability of the air conditioner.

[0289] like Figures 16-19 As shown, according to some embodiments of the present invention, a fixing member is provided inside the shell 1, and the plate heat exchanger 41 is disposed on the fixing member.

[0290] The fastener can be the outer shell of other components inside the housing 1, such as the gas-liquid separator 3, or a fixing structure inside the housing 1, such as a bracket or support plate.

[0291] It is understandable that by fixing the plate heat exchanger 41 with fasteners, the space inside the shell 1 can be made more fully and the space occupied can be improved.

[0292] In some embodiments of this utility model, the fixing member can be constructed as a partition 12, and the plate heat exchanger 41 is disposed on the side of the partition 12 facing the valve island assembly 5. The partition 12 can divide the accommodating space of the housing 1 into a fan chamber 13 and a compressor chamber 11. The plate heat exchanger 41 is disposed on the partition 12, and the projection of the plate heat exchanger 41 toward the partition 12 at least partially overlaps with the projection of the high pressure valve 46 toward the partition 12.

[0293] Specifically, one end of the partition 12 is connected to the bottom plate 15 of the shell 1, and the other end of the shell 1 is connected to the top cover 14 of the shell 1, so as to divide the fan chamber 13 and the compressor chamber 11 within the accommodating space of the shell 1. The plate heat exchanger 41 can be installed on the partition 12, and the mounting position of the plate heat exchanger 41 is set on the partition 12, eliminating the need for a separate mounting structure for the plate heat exchanger 41, which can reduce costs. Furthermore, the projection of the plate heat exchanger 41 and the high-pressure valve 46 toward the partition 12 at least partially overlaps, so that at least part of the plate heat exchanger 41... Located in the gap between the high-pressure valve 46 and the partition plate 12, not only can the space of the compressor cavity 11 be utilized more fully, but the portion of the plate heat exchanger 41 within the projection outline of the high-pressure valve 46 can be the closest to the high-pressure valve 46. At least part of the plate heat exchanger interface on the plate heat exchanger 41 can be correspondingly set within the projection outline, and straight pipe outlet can be achieved. One bend can not only further reduce the length of the high-pressure valve connecting pipe 461 and other connecting pipes led out from the plate heat exchanger 41, but also the pipe resistance of the straight pipe outlet is lower.

[0294] like Figures 16-19 As shown, according to some embodiments of the present invention, the projected profile of the high-pressure valve connecting pipe 461 toward the horizontal plane has a vertical dimension greater than or equal to 94 mm.

[0295] One end of the high-pressure valve connecting pipe 461 is connected to the high-pressure valve 46, and the other end extends toward the plate heat exchanger 41. Based on the installation position of the plate heat exchanger 41, the high-pressure valve connecting pipe 461 may be constructed to extend at an angle. The projected outline shape of the high-pressure valve connecting pipe 461 toward the vertical plane may be inclined relative to the vertical direction. This utility model defines the vertical dimension of the projected outline of the high-pressure valve connecting pipe 461 toward the vertical direction as the dimension in the vertical direction. If it is inclined relative to the vertical direction, the vertical dimension is the dimension obtained by further projecting the projected outline toward the vertical direction. In other words, the high-pressure valve connecting pipe 461 projects toward the vertical plane on the side where the partition plate 12 is located, and the dimension of the projection in the vertical direction is greater than or equal to 94mm.

[0296] It is understood that by making the vertical dimension of the high-pressure valve connecting pipe 461 greater than or equal to 94mm, this utility model can further limit the height difference between the plate heat exchanger interface of the plate heat exchanger 41 and the interface of the high-pressure valve connecting pipe 461 on the valve island assembly 5, or the height difference between the plate heat exchanger interface and the high-pressure valve interface of the high-pressure valve 46 itself. This makes the setting position of the plate heat exchanger 41 more reasonable, and the height difference between the plate heat exchanger 41 and the high-pressure valve 46 more reasonable. Sufficient space can be reserved between the plate heat exchanger 41 and the top cover 14 of the shell 1, and between the high-pressure valve 46 and the top cover 14, effectively reducing the space occupied by the plate heat exchanger 41 and the high-pressure valve 46 in the compressor cavity 11. At the same time, the height dimension of the plate heat exchanger 41 itself can also be specifically limited, and a more reasonable height plate heat exchanger 41 can be used to ensure the heat exchange effect and heat exchange efficiency of the plate heat exchanger 41.

[0297] Furthermore, the projected profile of the high-pressure valve connecting pipe 461 facing the vertical plane has a vertical dimension of less than or equal to 580 mm.

[0298] Therefore, the vertical dimension of the high-pressure valve connecting pipe 461 can be avoided from being too long. On the one hand, the high-pressure valve connecting pipe 461 can be bent towards the plate heat exchanger interface of the plate heat exchanger 41 to form an obtuse angle between the first pipe section connected to the plate heat exchanger 41 and the second pipe section of the high-pressure valve connecting pipe 461 that extends in a generally vertical direction, so as to reduce the flow resistance of the refrigerant. On the other hand, the vertical dimension of the high-pressure valve connecting pipe 461 is more reasonable, which can avoid the high-pressure valve connecting pipe 461 being too long and increasing the space occupation, so as to take into account the needs of compact and integrated layout and effectively reduce the space occupation.

[0299] Combination Figures 16-19 As shown, according to some embodiments of the present invention, the projected profile of the high-pressure valve connecting pipe 461 toward the horizontal plane has a horizontal dimension greater than or equal to 98 mm.

[0300] Specifically, based on the location of the plate heat exchanger 41, the high-pressure valve connecting pipe 461 may be constructed to extend at an angle. The projected outline of the high-pressure valve connecting pipe 461 toward the horizontal plane may be inclined relative to the length or width direction of the base plate 15. This utility model defines the horizontal dimension of the projected outline of the high-pressure valve connecting pipe 461 toward the base plate 15 as the dimension in the horizontal direction (e.g., if the plate heat exchanger 41 and the high-pressure valve 46 are opposite each other in the length direction of the base plate 15, then the horizontal dimension can be the dimension in the length direction of the base plate 15; or if the plate heat exchanger 41 and the high-pressure valve 46 are opposite each other in the width direction of the base plate 15, then the horizontal dimension can be the dimension in the width direction of the base plate 15). If the high-pressure valve connecting pipe 461 is inclined relative to the horizontal direction, then the horizontal dimension is the dimension obtained by further projecting the projected outline of the horizontal plane projected toward one side of the base plate 15 toward the width or length direction of the base plate 15. In other words, the high-pressure valve connecting pipe 461 is projected toward the horizontal plane on the side where the base plate 15 is located, and the dimension of the projected outline in the horizontal direction is greater than or equal to 98 mm.

[0301] Furthermore, this utility model ensures that the horizontal dimension of the high-pressure valve connecting pipe 461 is greater than or equal to 98mm, which further limits the horizontal distance between the plate heat exchanger 41 and the high-pressure valve 46, making the distance between the plate heat exchanger 41 and the high-pressure valve 46 more reasonable. This makes the installation position of the plate heat exchanger 41 more reasonable, and the distance between the plate heat exchanger 41 and the high-pressure valve 46 more reasonable. This not only avoids interference but also makes full use of the space inside the compressor cavity and reduces the difficulty of installing the plate heat exchanger 41 and the high-pressure valve 46.

[0302] It should be noted that the projected profile of the high-pressure valve connecting pipe 461 toward the horizontal plane has a horizontal dimension of less than or equal to 185 mm.

[0303] This avoids the high-pressure valve connecting pipe 461 from being too long horizontally. On the one hand, the high-pressure valve connecting pipe 461 can be bent towards the plate heat exchanger interface of the plate heat exchanger 41 to form an obtuse angle between the first pipe section connected to the plate heat exchanger 41 and the second pipe section of the high-pressure valve connecting pipe 461 that extends generally in the vertical direction, thereby reducing the flow resistance of the refrigerant. On the other hand, the horizontal dimension of the high-pressure valve connecting pipe 461 is more reasonable, which can avoid the horizontal distance between the plate heat exchanger 41 and the valve island assembly 5 being too large, so as to take into account the requirements of compact and integrated layout and effectively reduce space occupation.

[0304] In some embodiments, the high-pressure valve connecting pipe 461 may include a first pipe section extending generally in a horizontal direction and a second pipe section extending generally in a vertical direction. The total length of the first and second pipe sections is greater than or equal to 110 mm. The vertical dimension of the projected profile of the high-pressure valve connecting pipe 461 toward the partition 12 is the same as the vertical dimension of the projected profile of the second pipe section. This dimension is greater than or equal to 94 mm and should be less than or equal to 580 mm. This corresponds to the vertical distance between the interface connecting the plate heat exchanger 41 and the high-pressure valve 46 and the high-pressure valve 46 being greater than or equal to 94 mm and less than or equal to 580 mm. The horizontal dimension of the projected profile of the high-pressure valve connecting pipe 461 toward the horizontal plane on the side where the base plate 15 is located is greater than or equal to 98 mm and should be less than or equal to 185 mm. This corresponds to the horizontal distance between the plate heat exchanger 41 and the high-pressure valve 46 being greater than or equal to 98 mm and less than or equal to 185 mm. This can effectively avoid interference between the plate heat exchanger 41, the high-pressure valve connecting pipe 461 and surrounding components, and make full use of the gap between the partition 12 and the high-pressure valve 46.

[0305] It is understood that the vertical distance between the plate heat exchanger interface connecting the plate heat exchanger 41 and the high-pressure valve 46 and the high-pressure valve 46 should be greater than or equal to 94 mm and less than or equal to 580 mm. The horizontal distance between the plate heat exchanger 41 and the high-pressure valve 46 should be greater than or equal to 98 mm and less than or equal to 185 mm. This means that the dimension less than or equal to is a technical solution, and such a limitation can achieve certain technical effects. The dimension greater than or equal to is a technical solution, and the two are parallel technical solutions that can be selectively implemented by those skilled in the art based on the description of this application.

[0306] It should be noted that the length of the high-pressure valve connecting pipe 461 involved in the embodiments of this utility model refers to the distance between the plate heat exchanger interfaces of the high-pressure valve 46, or the distance between the high-pressure valve interface on the valve island assembly 5 and the plate heat exchanger interface on the plate heat exchanger 41 used to connect the high-pressure valve 46 and the valve port on the plate heat exchanger 41 used to connect the high-pressure valve 46. If the valve port of the high-pressure valve 46 is located on the side of the high-pressure valve 46, then the length of the high-pressure valve connecting pipe 461 refers to the distance between the valve port on the side of the high-pressure valve 46 and the plate heat exchanger interface on the surface of the plate heat exchanger 41 facing the high-pressure valve 46 used to connect the high-pressure valve connecting pipe 461. Since the high-pressure valve connecting pipe 461 can be arranged at an incline and bend, this utility model further defines the vertical and horizontal dimensions of the high-pressure valve connecting pipe 461. The vertical dimension is the projection dimension of the vertical plane projection dimension in the vertical direction, and the horizontal dimension is the projection dimension of the horizontal plane projection dimension in the horizontal direction.

[0307] like Figures 16-19As shown, according to some embodiments of the present invention, the air conditioner 100 further includes a low-pressure valve 47, which is connected to the plate heat exchanger 41, and the high-pressure valve 46 and the low-pressure valve 47 are led out on the same side.

[0308] Specifically, the high-pressure valve 46 and the low-pressure valve 47 can be led out from the same side of the valve island assembly 5, so that the high-pressure valve 46 and the low-pressure valve 47 can be set on the same side of the valve island assembly 5. This avoids the high-pressure valve 46 and the low-pressure valve 47 being set on different sides, which would increase the space occupation and reduce the difficulty of layout. At the same time, it can also make the installation of the low-pressure valve 47 and the high-pressure valve 46 easier, and the length of the piping led out from the valve island assembly 5 for connecting to the high-pressure valve 46 and the low-pressure valve 47 can be shorter.

[0309] The low-pressure valve 47 and the high-pressure valve 46 are led out from the front or rear side of the valve island assembly 5. The plate heat exchanger 41 is located on the adjacent side of the valve island assembly 5. Alternatively, the low-pressure valve 47 and the high-pressure valve 46 can be separated from the plate heat exchanger 41. The placement of the three valves is more reasonable, and the spacing between them is more reasonable, which can reduce the difficulty of layout and reduce the probability of interference. For example, the low-pressure valve 47 is connected to the valve island assembly 5 through the low-pressure valve connecting pipe 471.
