Technical Field

[0001] This utility model mainly relates to the field of air handling equipment technology, and in particular to an air conditioner. Background Technology

[0002] In the prior art, the compressor cavity of an air conditioner contains an electronic control component and a compressor component.

While the first pipe connects to the exhaust port of the refrigerant piping assembly and the compressor body, it provides ample installation space for other components within the air conditioner, resulting in a more rational internal layout. Furthermore, the first pipe is spaced apart from other components within the air conditioner. When the air conditioner is operating, the compressor body vibrates, causing the first pipe to vibrate. Since there is no direct connection between the first pipe and other components within the air conditioner, vibration of the first pipe avoids damage to other components caused by vibration.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a housing 1, a compressor assembly 2, and a valve island assembly 5.

[0029] 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.

[0030] Specifically, the air conditioner 100 is provided with a casing 1, which is located on the outside of the air conditioner 100 and thus provides support for the air conditioner 100. An installation space is formed inside the casing 1, within which various structures required for the operation of the air conditioner 100 can be installed. The casing 1 protects these structures and also provides mounting points for the internal structures of the air conditioner 100, ensuring installation reliability. like Figure 1As shown, the compressor assembly 2 includes a compressor body 21 and a refrigerant piping assembly 3. A valve island assembly 5 is located on one side of the compressor body 21 in the vertical direction. Multiple refrigerant piping assemblies 3 are connected to the valve island assembly 5 and communicate with the compressor body 21 to form a refrigerant circuit. The refrigerant circuit includes a first pipe 23, on which a clearance structure 2311 is defined. While the first pipe 23 connects the refrigerant piping assembly 3 and the exhaust port of the compressor body 21, it also provides ample installation space for other components within the air conditioner 100, resulting in a more rational internal layout.

[0031] Meanwhile, the first pipe 23 is separated from other components inside the air conditioner 100. When the air conditioner 100 is working, the compressor body 21 vibrates, which drives the first pipe 23 to vibrate. There is no direct connection between the first pipe 23 and other components inside the air conditioner 100, so as to avoid the vibration of other components inside the air conditioner 100 caused by the vibration of the first pipe 23, and to avoid damage to other components inside the air conditioner 100 due to vibration.

[0032] According to an embodiment of the present invention, the air conditioner 100 is connected to the refrigerant piping assembly 3, the valve island assembly 5, and the compressor body 21 via a first pipe 23 to form a refrigerant circuit. A clearance structure 2311 is defined on the first pipe 23 in the refrigerant circuit. While the first pipe 23 connects the refrigerant piping assembly 3 and the exhaust port of the compressor body 21, it provides sufficient installation space for other components within the air conditioner 100, resulting in a more reasonable internal layout. Furthermore, the first pipe 23 is spaced apart from other components within the air conditioner 100. When the air conditioner 100 is operating, the compressor body 21 vibrates, causing the first pipe 23 to vibrate. Since there is no direct connection between the first pipe 23 and other components within the air conditioner 100, vibration of the first pipe 23 is avoided, preventing damage to other components within the air conditioner 100 due to vibration.

[0033] 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.

[0034] The refrigerant piping assembly 3 includes a four-way valve 22, which is located above the compressor body 21. The four-way valve 22 is connected to the exhaust port of the compressor body 21 via a first pipe 23. The upper end of the first pipe 23 defines a clearance structure 2311 to avoid the electronic control assembly. While the first pipe 23 connects the four-way valve 22 and the exhaust port of the compressor body 21, it also provides sufficient installation space for the electronic control assembly, making the layout of the compressor cavity 111 more reasonable.

[0035] Meanwhile, the first tube 23 is separated from the electronic control component. When the air conditioner 100 is working, the compressor body 21 vibrates, which drives the first tube 23 to vibrate. There is no direct connection between the first tube 23 and the electronic control component, so as to avoid the vibration of the electronic control component caused by the vibration of the first tube 23, and to avoid damage to the precision circuit inside the electronic control component due to vibration.

[0036] In some embodiments of this utility model, such as Figure 1-2 As shown, the housing 1 is provided with a partition 11. The partition 11 is used to divide the housing 1 into a compressor chamber 111 and a fan chamber that are spaced apart in the horizontal direction. The partition 11 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.

[0037] A fan assembly can be installed inside the fan cavity. 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 rotation of the fan blades can dissipate heat and cool the heat exchanger to ensure the stability of the heat exchanger's operation.

[0038] The compressor assembly 2 is installed inside the compressor cavity 111. Thus, the fan cavity and the compressor cavity 111 can be separated by the partition 11. When the drive motor, fan blades and compressor body 21 are running, the partition 11 can block the vibration between the fan cavity and the compressor cavity 111, so as to avoid interference between the structure inside the fan cavity and the structure inside the compressor cavity 111, and ensure the reliability of the air conditioner 100.

[0039] The electronic control component is located inside the compressor cavity 111. The electronic control component can be installed on the front side panel of the housing 1, or on the side panel of the housing 1, or on the partition 11 of the housing 1.

[0040] In this embodiment, the electronic control component is located inside the compressor cavity 111 and connected to the partition 11. The upper end of the first pipe 23 facing the fan cavity defines a clearance structure 2311 to avoid the electronic control component. While the first pipe 23 connects the four-way valve 22 and the exhaust port of the compressor body 21, it can provide sufficient installation space for the electronic control component, making the layout of the compressor cavity 111 more reasonable.

[0041] In some embodiments of this utility model, such as Figure 3-4 As shown, the air conditioner 100 also includes a refrigerant piping assembly 3, a tank assembly 4, and a valve island assembly 5. There are multiple refrigerant piping assemblies 3. The tank assembly 4 is connected to the inner bottom wall of the casing 1. The valve island assembly 5 is installed and supported on the tank assembly 4. Multiple refrigerant piping assemblies 3 are connected to the valve island assembly 5 and are connected to the compressor body 21 and the tank assembly 4 to form a refrigerant circuit.

[0042] The valve island assembly 5 can be installed and supported on the tank assembly 4 by means of connectors or welding, and the tank assembly 4 can be connected to the housing 1 by means of connectors or welding. The compressor body 21 is spaced apart from the tank assembly 4 and can also be connected to the housing 1 by means of connectors or welding. Thus, the valve island assembly 5 can be fixedly installed in the housing 1 only by the tank assembly 4. Multiple refrigerant pipeline assemblies 3 can be connected to the valve island assembly 5, and multiple refrigerant pipeline assemblies 3 can be connected to the compressor body 21 and the tank assembly 4 to form a refrigerant circuit. This allows the valve island assembly 5 to be spaced apart from the compressor body 21 and other structures to isolate the vibration generated by the compressor body 21 and other structures during operation, thereby reducing the noise generated by the air conditioner 100 during operation and improving the user experience.

[0043] In addition, multiple refrigerant piping assemblies 3 are connected to valve island assembly 5, which shortens the length of the refrigerant piping and reduces the space occupied by multiple refrigerant piping, thereby improving integration and weight reduction, and reducing installation costs. At the same time, it can reduce the number of connection points of multiple refrigerant piping, thereby reducing the risk of leakage of refrigerant and other media and improving the reliability of air conditioner 100.

[0044] In some embodiments of this utility model, such as Figure 5 As shown, the first pipe 23 includes a first sub-pipe 231 and a second sub-pipe 232. The first sub-pipe 231 extends vertically. One end of the second sub-pipe 232 is connected to the lower end of the first sub-pipe 231 along its length, and the other end extends away from the first sub-pipe 231 to form a clearance space. It can be understood that the connection of one end of the second sub-pipe 232 to the lower end of the first sub-pipe 231 and the extension of the other end towards the fan cavity allows the first pipe 23 to extend towards the fan cavity. The first pipe 23 connects the four-way valve 22 and the compressor body 21. Along the direction from the four-way valve 22 to the second sub-pipe 232, the portion of the first pipe 23 located downstream of the second sub-pipe 232 can provide space for other pipes. The first sub-pipe 231 and the second sub-pipe 232 together constitute a clearance structure 2311. The first sub-pipe 231 and the second sub-pipe 232 can provide sufficient installation space for the electronic control components, making the layout of the compressor cavity 111 more reasonable.

[0045] In this embodiment, the second sub-pipe 232 can avoid the four-way valve 22, increasing the rationality of the layout of the compressor cavity 111.

[0046] In some embodiments of this utility model, such as Figure 5As shown, the two ends of the second sub-pipe 232 along its length are a first end 2321 and a second end 2322, respectively. The first end 2321 is connected to the lower end of the first sub-pipe 231. The direction from the first end 2321 to the second end 2322 is a first direction, which forms an angle with both the horizontal and vertical directions. The second sub-pipe 232, while forming an avoidance structure 2311, can reduce the total length of the first pipe 23 and increase the flow rate of the refrigerant. At the same time, the flow of refrigerant in the first pipe 23 is smoother than with a right-angle bend, avoiding any impact on the flow of refrigerant.

[0047] In some embodiments of this utility model, such as Figure 5 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 232 and the vertically arranged first sub-pipe 231 approaching a right angle. This ensures smoother refrigerant flow within the first sub-pipe 231 and the second sub-pipe 232 compared to a right-angle bend, preventing disruption to refrigerant flow.

[0048] In some embodiments of this utility model, such as Figure 5 As shown, a first arc-shaped connecting portion 236 is provided between the first sub-tube 231 and the second sub-tube 232, making the connection between the first sub-tube 231 and the second sub-tube 232 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. Simultaneously, it increases the elasticity of the first tube 23, reducing the risk of damage to the first tube 23 due to vibration and other issues.

[0049] In some embodiments of this utility model, the radius of the arc of the first arc connecting portion 236 is R1, and satisfies: 15mm ≤ R1 ≤ 25mm. It can be understood that the radius of the arc of the first arc connecting portion 236 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 231 and the second sub-pipe 232, preventing obstruction of refrigerant flow. A radius of arc of no more than 25mm avoids a larger size for the first arc connecting portion 236, preventing an increase in the manufacturing material of the first pipe 23 and thus avoiding an increase in the manufacturing cost of the first pipe 23.

[0050] In this embodiment, the radius of the first arc connecting part 236 is the radius of the arc at the axis of the first arc connecting part 236.

[0051] In some embodiments of this utility model, such as Figure 5 As shown, the first pipe 23 also includes a third sub-pipe 233, a fourth sub-pipe 234, and a fifth sub-pipe 235. The third sub-pipe 233 extends vertically, and its lower end is connected to the refrigerant piping assembly 3, which is a four-way valve 22 in this embodiment. The fourth sub-pipe 234 extends horizontally, with one end connected to the upper end of the third sub-pipe 233 and the other end connected to the upper end of the first sub-pipe 231. The fourth sub-pipe 234 can extend the first pipe 23 horizontally to avoid the area of ​​the four-way valve 22, thus increasing the rationality of the layout. One end of the fifth sub-pipe 235 is connected to the end of the second sub-pipe 232 that is away from the first sub-pipe 231, and the other end is connected to the exhaust port 211 of the compressor body 21.

[0052] It is understandable that the refrigerant discharged from the exhaust pipe of the compressor body 21 flows from the fifth sub-pipe 235 to the second sub-pipe 232, then to the first sub-pipe 231, and finally through the fourth sub-pipe 234 to the third sub-pipe 233, and enters the four-way valve 22. The connection port of the four-way valve 22, which is connected to the third sub-pipe 233, is located at the upper end of the four-way valve 22. The layout of the first pipe 23 is relatively reasonable.

[0053] In some embodiments of this utility model, such as Figure 5 As shown, a second arc-shaped connecting portion 237 is provided between the first sub-pipe 231 and the fourth sub-pipe 234, making the connection between the first sub-pipe 231 and the fourth sub-pipe 234 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. Simultaneously, it increases the elasticity of the first pipe 23, reducing the risk of damage to the first pipe 23 due to vibration and other issues.

[0054] In some embodiments of this utility model, such as Figure 5 As shown, a third arc-shaped connecting portion 238 is provided between the second sub-tube 232 and the fifth sub-tube 235, making the connection between the second sub-tube 232 and the fifth sub-tube 235 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. Simultaneously, it increases the elasticity of the first tube 23, reducing the risk of damage to the first tube 23 due to vibration and other issues.

[0055] In some embodiments of this utility model, such as Figure 5As shown, a fourth arc-shaped connecting portion 239 is provided between the third sub-tube 233 and the fourth sub-tube 234, making the connection between the third sub-tube 233 and the fourth sub-tube 234 smoother, facilitating the flow of the cooling medium, and reducing stress concentration caused by right-angle bends. Simultaneously, it increases the elasticity of the first tube 23, reducing the risk of damage to the first tube 23 due to vibration and other issues.

[0056] In some embodiments of this utility model, the radius of the arc of the second arc connecting portion 237 is R2, and satisfies: 15mm ≤ R2 ≤ 25mm. It can be understood that the radius of the arc of the second arc connecting portion 237 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 231 and the fourth sub-pipe 234, preventing obstruction of refrigerant flow. A radius of arc of no more than 25mm avoids a larger size for the second arc connecting portion 237, preventing an increase in the manufacturing material of the first pipe 23 and thus avoiding an increase in the manufacturing cost of the first pipe 23.

[0057] In this embodiment, the radius of the second arc connecting part 237 is the radius of the arc at the axis of the second arc connecting part 237.

[0058] In some embodiments of this utility model, the radius of the arc of the third arc connecting portion 238 is R3, and satisfies: 15mm ≤ R3 ≤ 25mm. It is understandable that the radius of the arc of the third arc connection 238 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. A radius of no more than 15mm for the third arc connection 238 avoids a too abrupt transition between the second sub-pipe 232 and the fifth sub-pipe 235, preventing obstruction of refrigerant flow. A radius of no more than 25mm for the third arc connection 238 avoids a larger size, preventing an increase in the manufacturing material of the first pipe 23 and thus avoiding an increase in the manufacturing cost of the first pipe 23.

[0059] In this embodiment, the radius of the arc of the third arc connecting part 238 is the radius of the arc at the axis of the third arc connecting part 238.

[0060] In some embodiments of this utility model, the radius of the fourth arc connecting portion 239 is R4, and satisfies: 15mm ≤ R4 ≤ 25mm. It can be understood that the radius of the fourth arc connecting portion 239 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm. Having a radius of no more than 15mm avoids a sharp transition between the third sub-pipe 233 and the fourth sub-pipe 234, preventing obstruction of refrigerant flow. Similarly, having a radius of no more than 25mm avoids a large size for the third arc connecting portion 238, preventing an increase in the manufacturing material of the first pipe 23 and thus reducing its manufacturing cost.

[0061] In this embodiment, the radius of the arc of the fourth arc connecting part 239 is the radius of the arc at the axis of the fourth arc connecting part 239.

[0062] In some embodiments of this utility model, the length of the second sub-pipe 232 in the horizontal direction is L1, and satisfies: 20mm≤L1≤115mm. It can be understood that the length of the second sub-pipe 232 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 232 is not less than 20mm, allowing it to be horizontally separated from the four-way valve 22, thus enabling the avoidance structure 2311 to avoid other structures in the horizontal direction. The length of the second sub-pipe 232 is not more than 115mm, preventing interference between the second sub-pipe 232 and other components in the horizontal direction, increasing the rationality of the internal spatial layout of the air conditioner 100.

[0063] The length of the second sub-tube 232 is measured based on the length between the end point near the first arc connecting part 236 and the end point near the third arc connecting part 238.

[0064] In some embodiments of this utility model, the length of the first sub-tube 231 is L2 and the length of the third sub-tube 233 is L3 in the vertical direction, satisfying: -15mm ≤ L2 - L3 ≤ 15mm. It can be understood that the length difference between the first sub-tube 231 and the third sub-tube 233 in the vertical direction can be -15mm, -10mm, -5mm, 0mm, 5mm, 10mm, or 15mm. The lengths of the first sub-tube 231 and the third sub-tube 233 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.

[0065] The length of the first sub-tube 231 is measured based on the length between the end near the first arc connecting part 236 and the end near the second arc connecting part 237. The length of the third sub-tube 233 is measured based on the length between the end near the fourth arc connecting part 239 and the end near the four-way valve 22.

[0066] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the air conditioner 100 also includes a refrigerant piping assembly 3, a tank assembly 4, and a valve island assembly 5. There are multiple refrigerant piping assemblies 3. The tank assembly 4 is connected to the inner bottom wall of the casing 1. The valve island assembly 5 is installed and supported on the tank assembly 4. Multiple refrigerant piping assemblies 3 are connected to the valve island assembly 5 and are connected to the compressor body 21 and the tank assembly 4 to form a refrigerant circuit.

[0067] The valve island assembly 5 can be installed and supported on the tank assembly 4 by means of connectors or welding, and the tank assembly 4 can be connected to the housing 1 by means of connectors or welding. The compressor body 21 is spaced apart from the tank assembly 4 and can also be connected to the housing 1 by means of connectors or welding. Thus, the valve island assembly 5 can be fixedly installed in the housing 1 only by the tank assembly 4. Multiple refrigerant pipeline assemblies 3 can be connected to the valve island assembly 5, and multiple refrigerant pipeline assemblies 3 can be connected to the compressor body 21 and the tank assembly 4 to form a refrigerant circuit. This allows the valve island assembly 5 to be spaced apart from the compressor body 21 and other structures to isolate the vibration generated by the compressor body 21 and other structures during operation, thereby reducing the noise generated by the air conditioner 100 during operation and improving the user experience.

[0068] In addition, multiple refrigerant piping assemblies 3 are connected to valve island assembly 5, which shortens the length of the refrigerant piping and reduces the space occupied by multiple refrigerant piping, thereby improving integration and weight reduction, and reducing installation costs. At the same time, it can reduce the number of connection points of multiple refrigerant piping, thereby reducing the risk of leakage of refrigerant and other media and improving the reliability of air conditioner 100.

[0069] In some embodiments of this utility model, such as Figure 1-2 As shown, the valve island assembly 5 includes a valve island body 51 and a valve island bracket 52. The valve island bracket 52 is mounted and supported on the tank assembly 4, and the valve island body 51 is supported above the valve island bracket 52. Multiple refrigerant piping assemblies 3 and four-way valves 22 are connected to the valve island body 51.

[0070] Specifically, the valve island assembly 5 is mounted and supported on the tank assembly 4, and 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 mounted on the tank assembly 4 by welding or connecting parts, and the valve island body 51 can be mounted and supported on top of the valve island bracket 52, so that the valve island body 51 can be mounted and supported on the tank assembly 4 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 tank assembly 4, 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.

[0071] Furthermore, multiple refrigerant piping components 3 are connected to the valve island body 51, which can shorten the length of the refrigerant piping, improve integration, reduce the space occupied by multiple refrigerant piping, 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.

[0072] The unit with internal flow channels can be referred to as the valve island body 51. Furthermore, the valve island body 51 may also include valve bodies such as a solenoid valve 34, an electronic expansion valve, and a four-way valve, which are connected to the flow channels via interfaces. 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 valves, the valve island body 51 can regulate fluid flow and pressure, thereby improving the automation level of the air conditioner 100.

[0073] Furthermore, if the tank assembly 4 has a refrigerant pipeline or functions to act on refrigerant, the tank assembly 4 has a gas distribution pipeline connected to the pipeline interface on the valve island body 51, and the gas distribution pipeline is connected to the pipeline of the valve island body 51 and the refrigerant pipeline assembly 3.

[0074] In some embodiments of this utility model, such as Figure 1 As shown, Figure 1 As shown, at least a portion of the valve island bracket 52 is spaced apart from the valve island body 51 and together defines the installation area. The refrigerant piping assembly 3 includes a plate heat exchanger 31 and a four-way valve 22. The plate heat exchanger 31 is connected to the valve island body 51 and located within the installation area. The four-way valve 22 is located above the compressor body 21. The plate heat exchanger 31 and the four-way valve 22 are connected through the valve island body 51.

[0075] Specifically, multiple refrigerant piping assemblies 3 are equipped with plate heat exchangers 31. The plate heat exchanger 31 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 is carried out through the plates. As shown in Figure 1-2, the plate heat exchanger 31 can be connected to the valve island body 51, so that the plate heat exchanger 31 can also be installed only on the valve island body 51, thereby isolating vibration.

[0076] Furthermore, such as Figure 2 As shown, the valve island body 51 is installed on the tank assembly 4 via the valve island bracket 52, and at least a portion of the valve island bracket 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 bracket 52 to connect to the tank assembly 4, and another portion of the valve island body 51 can be spaced apart from the valve island bracket 52, so that the other portion of the valve island body 51 and the valve island bracket 52 can jointly define the installation area, and the plate heat exchanger 31 can be set in the installation area.

[0077] Thus, the valve island bracket 52 can support both the valve island body 51 and the plate heat exchanger 31, ensuring the reliable installation of both. It also allows the valve island body 51 and the plate heat exchanger 31 to be connected to the tank assembly 4 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 31 to the valve island body 51 reduces the need for refrigerant piping, lowering installation costs, and increasing integration for weight reduction.

[0078] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the refrigerant piping assembly 3 also includes an oil-gas separator 32, an electronic expansion valve 33, a solenoid valve 34, a high-pressure valve 35, and a low-pressure valve 36. The oil-gas separator 32, the electronic expansion valve 33, the solenoid valve 34, the high-pressure valve 35, and the low-pressure valve 36 are all connected to the valve island assembly 5. The oil-gas separator 32 can separate the refrigerant oil discharged from the compressor body 21 and return it to the compressor body 21 through the oil return pipeline, ensuring the reliability of the compressor body 21. The oil-gas separator 32 can be connected to the compressor body 21 and the four-way valve 22 respectively.

[0079] Furthermore, the four-way valve 22 can be used to switch between cooling and heating modes and change the refrigerant flow direction. In cooling mode, the four-way valve 22 can be connected to the plate heat exchanger 31. At this time, the plate heat exchanger 31 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 four-way valve 22 can be connected to the indoor unit of the air conditioner. At this time, the plate heat exchanger 31 acts as an evaporator, where low-temperature and low-pressure liquid absorbs heat and vaporizes. The plate heat exchanger 31 is also connected to the electronic expansion valve 33, which can throttle and reduce pressure, regulate the refrigerant flow, and ensure the reliable operation of the air conditioner 100.

[0080] Furthermore, the high-pressure valve 35 can connect to the high-pressure pipeline between the outdoor unit and the indoor unit of the air conditioner, and is usually located at the outlet of the plate heat exchanger 31 or the electronic expansion valve 33. The low-pressure valve 36 connects to the low-pressure pipeline between the outdoor unit and the indoor unit of the air conditioner, and is usually connected to the four-way valve 22 or the tank assembly 4. The tank assembly 4 can store excess refrigerant to prevent liquid refrigerant from entering the compressor body 21 and ensure the reliable operation of the compressor body 21. In addition, the solenoid valve 34 can be set as a single-way solenoid valve 34. The single-way solenoid valve 34 can control the flow of refrigerant, such as cutting off part of the circuit during defrosting. The single-way solenoid valve 34 can be connected in series in the high-pressure pipeline or the bypass pipeline to increase the application scenarios of the air conditioner 100.

[0081] In some embodiments, such as Figure 5 As shown, the air conditioner 100 also includes: a gas separation mounting bracket 6, and the tank assembly 4 is detachably connected to the bottom wall of the housing 1 via the gas separation mounting bracket 6.

[0082] Specifically, the air conditioner 100 is also provided with a gas distribution mounting bracket 6, which is installed at the bottom of the tank assembly 4. The tank assembly 4 can be detachably connected to the bottom wall of the casing 1 through the gas distribution mounting bracket 6. That is, the tank assembly 4 can be connected to the gas distribution mounting bracket 6 through connectors, and the gas distribution mounting bracket 6 can also be connected to the bottom wall of the casing 1 through connectors. This makes the tank assembly 4 detachable from the bottom wall of the casing 1, which facilitates the later maintenance of the tank assembly 4. Furthermore, the connection between the tank assembly 4 and the bottom wall of the casing 1 through the gas distribution mounting bracket 6 reduces the contact area between the tank assembly 4 and the casing 1, thereby reducing the transmission of vibration from the tank assembly 4 to the casing 1, reducing the noise generated during the operation of the air conditioner 100, and improving the user experience.

[0083] In some embodiments, such as Figure 5 As shown, the gas separation mounting bracket 6 includes a mounting top plate 61, an intermediate plate 62, and a mounting bottom plate 63. The mounting top plate 61 and the mounting bottom plate 63 are spaced apart and opposite to each other and connected to the two ends of the intermediate plate 62. The bottom of the tank assembly 4 is supported by the mounting top plate 61, and the mounting bottom plate 63 is supported by the bottom wall of the housing 1.

[0084] Specifically, the tank assembly 4 can be detachably connected to the bottom wall of the housing 1 via the gas separation mounting bracket 6. As shown in the figure, the gas separation mounting bracket 6 is provided with a top mounting plate 61, an intermediate 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 intermediate 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 tank assembly 4 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.

[0085] By setting 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 tank assembly 4 can be increased, as can the contact area between the mounting bottom plate 63 and the bottom wall of the casing 1, ensuring reliable 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.

[0086] In addition, a gas separator mounting bracket 6 is provided at the bottom of the tank assembly 4, so that there is a height difference between the top of the tank assembly 4 and the top of the compressor body 21. This allows the valve island assembly 5 to be staggered from the top of the compressor body 21, 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 second limiting flanges. The second limiting flange of the mounting top plate 61 can limit the tank assembly 4 to ensure installation reliability, and the second limiting flange 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 tank assembly 4.
