[0002] In related technologies, air conditioners have a valve island assembly, which is composed of multiple valve bodies and corresponding pipes and interfaces. In some existing technologies, the valve island assembly is integrated into the compressor, but the compressor pipes and valve island 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.

[0034] In related technologies, air conditioners have a valve island assembly, which is composed of multiple valve bodies and corresponding pipes and interfaces. In some existing technologies, the valve island assembly is integrated into the compressor, but the compressor pipes and valve island 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.

[0035] The following is for reference. Figures 1-4 The compressor assembly 1 according to an embodiment of the present invention is described.

[0036] like Figures 1-4 As shown, the compressor assembly 1 according to this utility model includes: a compressor body 10, a valve island assembly 20, a first pipeline 30, and a second pipeline 40. The compressor body 10 has an exhaust port. The valve island assembly 20 has a flow channel formed inside, and the valve island assembly 20 also has multiple flow channel interfaces communicating with the flow channel. The multiple flow channel interfaces include at least a first interface 20a and a second interface. The first pipeline 30 is connected to the exhaust port and the first interface 20a, and the first pipeline 30 has a top pipe section 31. The second pipeline 40 is connected to the second interface, and the second pipeline 40 does not protrude beyond the top pipe section 31 in the height direction.

[0037] Specifically, the compressor body 10, the valve island assembly 20, and the pipeline connected to the valve island assembly 20 are suitable for circulating heat exchange medium. The compressor body 10 is suitable for providing power for the circulation of heat exchange medium in the whole system. It is suitable for drawing in low-temperature and low-pressure gaseous heat exchange medium through the return gas port, compressing it into high-temperature and high-pressure gaseous heat exchange medium, and then discharging it through the exhaust port.

[0038] The compressor body 10, valve island assembly 20, and piping connected to the valve island assembly 20 can be integrated into one unit to form compressor assembly 1. In compressor assembly 1, valve island assembly 20 has multiple flow channel interfaces. These interfaces can connect valve island assembly 20 to other structures integrated into compressor assembly 1, connect valve island assembly 20 to structures outside compressor assembly 1, or connect any two flow channel interfaces. Furthermore, flow channel interfaces can be directly connected to each other, or indirectly connected to other structures via piping, depending on the specific requirements of the design.

[0039] More specifically, among the multiple flow channel interfaces, at least a first interface 20a and a second interface are included. The first interface 20a is connected to the exhaust port of the compressor body 10 via a first pipe 30, which has a top pipe section 31. The second interface is connected to other structures outside the valve island assembly 20 via a second pipe 40, or the second interface is connected to other flow channel interfaces of the valve island assembly 20 via a second pipe 40. The second pipe 40 does not protrude beyond the top pipe section 31 in the height direction, so that among the pipes integrated in the valve island assembly 20, at least one pipe does not protrude beyond the top pipe section 31 of the first pipe 30 in the height direction, that is, the second pipe 40 does not protrude beyond the top pipe section 31 of the first pipe 30 in the height direction.

[0040] In such Figures 1-2 In the illustrated embodiment, the valve island assembly 20 is disposed on one side of the compressor body 10 in the height direction, and the top pipe section 31 is located on the side of the valve island assembly 20 away from the compressor body 10 in the height direction. The second pipe 40 can be designed so that it does not protrude beyond the top pipe section 31 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 20 can be used as the boundary, with the compressor body 10 located on the first side 201 of the valve island assembly 20 in the height direction, and the top pipe section 31 located on the second side 202 of the valve island assembly 20 in the height direction.

[0041] At this time, at least a portion of the second pipe 40 in the height direction can extend toward the compressor body 10, that is, at least a portion of the second pipe 40 extends toward the first side 201, so that the second pipe 40 and the compressor body 10 overlap in the height direction, reducing the space occupied by the second pipe 40 on the second side 202; or, at least a portion of the second pipe 40 in the height direction can extend toward the top pipe section 31 and not protrude from the top pipe section 31 in the height direction, that is, at least a portion of the second pipe 40 extends toward the second side 202 and is located between the top pipe section 31 and the valve island assembly 20, so that the second pipe 40 and the top pipe section 31 overlap in the height direction, reducing the space occupied by the second pipe 40 on the second side 202.

[0042] The compressor assembly 1 designed according to this utility model integrates a compressor body 10, a valve island assembly 20, and pipelines connected to the valve island assembly 20. The pipelines connected to the valve island assembly 20 include at least a first pipeline 30 and a second pipeline 40. The first pipeline 30 connects the first interface 20a of the valve island assembly 20 to the exhaust port of the compressor body 10 and has a top pipe section 31. The second pipeline 40 connects the second interface of the valve island assembly 20 to other structures outside the valve island assembly 20 or other flow channel interfaces of the valve island assembly 20. The second pipeline 40 is designed not to protrude beyond the top pipe section 31 in the height direction, so that the second pipeline 40 and the compressor assembly... The other structures of component 1 overlap in the height direction, eliminating the need for additional space for the second pipe 40 in the height direction. This reduces the space required for the second pipe 40 in the height direction, improves the integration of compressor assembly 1, reduces the space occupied by compressor assembly 1, and prevents the second pipe 40 from interfering with the arrangement of other structures of compressor assembly 1 or structures outside compressor assembly 1. By limiting the arrangement positions of the first pipe 30 and the second pipe 40, the pipe arrangement of compressor assembly 1 can be optimized, facilitating the production, installation and maintenance of compressor assembly 1, and contributing to the miniaturization and weight reduction of products equipped with the compressor assembly 1.

[0043] Of course, the second interface can be constructed as one or more, and each second pipe 40 connected to the corresponding second interface is configured such that it does not protrude beyond the top pipe segment 31 of the first pipe 30 in the height direction.

[0044] Meanwhile, the flow channel interface may also include a third interface and other interfaces. The pipes connected to these interfaces may be configured such that none of them protrude from the top pipe section 31 in the height direction, or they may all protrude from the top pipe section 31 in the height direction. Alternatively, some pipes may not protrude from the top pipe section 31 in the height direction, while others may protrude from the top pipe section 31 in the height direction. Preferably, the pipes connected to the third interface and other interfaces are not protruding from the top pipe section 31 in the height direction. In this case, the multiple pipes connected to the valve island assembly 20 do not protrude from the top pipe section 31 of the first pipe 30 in the height direction, which makes the compressor assembly 1 have a higher degree of integration and occupy less space. Furthermore, by reducing the length of the pipes connected to the valve island assembly 20, the cost of the pipes set in the compressor assembly 1 can also be reduced.

[0045] According to some embodiments of this utility model, such as Figures 1-2 As shown, the valve island assembly 20 includes a valve island body 21 and a valve body. A flow channel is formed inside the valve island body 21. The valve body is configured as multiple valve bodies and is disposed on the valve island body 21. Each valve body is provided with a communication port 20b that communicates with the flow channel. One of the valve bodies is provided with a first interface 20a. The second interface is configured as at least one, and at least one of the valve island body 21 and the valve body is provided with a second interface.

[0046] Specifically, the valve island body 21 has the aforementioned flow channels formed inside. Multiple valve bodies are disposed within the valve island body 21, 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 may include a reversing valve, which enables mode switching, function selection, and system control of the compressor assembly 1, thereby enhancing the flexibility and functionality of the entire compressor assembly 1. The valve body may also include an expansion valve, typically an electronic expansion valve, which precisely controls the flow rate of the heat exchange medium entering other structures of the compressor assembly 1 by controlling the opening degree of the corresponding flow channel, achieving high efficiency, energy saving, and precise temperature control. The valve body may also include a solenoid valve 27, a check valve, etc., to control the flow of the heat exchange medium to different branches, ensuring that the system with the valve island assembly 20 can operate efficiently under various operating conditions.

[0047] Each valve body is connected to a flow channel, and one of the valve bodies is provided with a first interface 20a to connect to the exhaust port of the compressor body 10 via a first pipe 30, thereby connecting to the high-temperature and high-pressure gaseous heat exchange medium compressed by the compressor body 10. The second interface is constructed in at least one way; at least one of the valve island body 21 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 21 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 21 and others on the valve body, or all of the multiple second interfaces can be located on either the valve island body 21 or the valve body. Each second pipe 40 connected to the corresponding second interface is designed so that it does not protrude beyond the top pipe section 31 of the first pipe 30 in the height direction, thereby reducing the space required for the second pipe 40 in the height direction, improving the integration of the compressor assembly 1, and reducing the space occupied by the compressor assembly 1.

[0048] Furthermore, according to some embodiments of the present invention, such as Figures 1-2 As shown, the valve island body 21 has a first side 201 and a second side 202 in the height direction. The first side 201 is provided with a compressor body 10, and the second side 202 is provided with a top pipe section 31. 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 31 in the height direction.

[0049] As mentioned above, with the valve island body 21 as the boundary, the compressor body 10 is located on the first side 201 of the valve island body 21 in the height direction, the top pipe section 31 is located on the second side 202 of the valve island body 21 in the height direction, and the valve body is disposed on the valve island body 21 and is constructed in multiple ways. Optionally, multiple valve bodies are disposed on the first side 201 and / or the second side 202. Of course, the valve body can also be disposed between the first side 201 and the second side 202.

[0050] The valve body is such that at least one valve body does not protrude from the top pipe section 31 in the height direction, such that among the valve bodies integrated in the valve island assembly 20, at least one valve body does not protrude from the top pipe section 31 in the height direction.

[0051] At this time, at least a portion of the valve body in the height direction can extend toward the compressor body 10, 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 body 10 in the height direction overlaps, reducing the space occupied by the valve body on the second side 202.

[0052] Alternatively, at least a portion of the valve body extends toward the top pipe section 31 in the height direction and does not protrude beyond the top pipe section 31 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 31 and the valve island body 21, so that the placement space of the valve body and the top pipe section 31 overlaps in the height direction, reducing the space occupied by the valve body on the second side 202.

[0053] 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 21 overlaps in the height direction, thereby reducing the space occupied by the valve body in the height direction.

[0054] 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 31 in the height direction. The specific location of the valve body is not limited here.

[0055] According to some embodiments of this utility model, such as Figures 1-2 As shown, the valve body includes a first valve body 22, which is located on the second side 202 and is provided with a first interface 20a and a connecting port 20b. The first interface 20a is connected to the exhaust port through the first pipe 30, and the connecting port 20b is connected to the flow channel.

[0056] The valve body may include a first valve body 22, which is located on the second side 202 of the valve island body 21, and has a first interface 20a and a connecting port 20b respectively on both sides in the height direction. The first interface 20a is located on the side of the first valve body 22 away from the valve island body 21, and the connecting port 20b is located on the side of the first valve body 22 facing the valve island body 21.

[0057] You can refer to this. Figures 1-2 At this time, the first interface 20a is located at the top of the first valve body 22, and the connecting port 20b is located at the bottom of the first valve body 22. The heat exchange medium discharged from the exhaust port of the compressor body 10 can flow through the first pipeline 30 and into the first valve body 22 through the first interface 20a. Since the first interface 20a is located at the top of the first valve body 22 in the height direction, and the connecting port 20b is located at the bottom of the first valve body 22 in the height direction, the heat exchange medium can flow from the first interface 20a to the connecting port 20b under the action of gravity, thereby flowing into the flow channel, which can accelerate the flow speed of the heat exchange medium, thereby accelerating the working efficiency of the valve island assembly 20, and thus accelerating the working efficiency of the compressor assembly 1.

[0058] Meanwhile, since the first interface 20a is located at the top of the first valve body 22, the top pipe section 31 of the first pipeline 30 can be set at a higher position, and other pipelines connected to the valve island assembly 20 can be set below the top pipe section 31 to improve the integration of the compressor assembly 1, reduce the space occupied by the compressor assembly 1, facilitate production, installation and maintenance, and help to achieve miniaturization and weight reduction of the structure in which the compressor assembly 1 is installed.

[0059] According to some embodiments of this utility model, the first valve body 22 is a reversing valve. The reversing valve determines the flow direction of the heat exchange medium in the valve island assembly 20, thereby controlling the compressor assembly 1, which has the valve island assembly 20, for cooling or heating. It also enables mode switching, function selection, and system control of the compressor assembly 1, thereby enhancing the flexibility and functionality of the entire compressor assembly 1. Figures 1-2 In the embodiment shown, the first valve body 22 is a four-way valve.

[0060] According to some embodiments of this utility model, such as Figures 1-2 As shown, the extension direction of the first valve body 22 intersects the height direction. Multiple connection ports 20b are spaced apart along the extension direction of the first valve body 22. At least two connection ports 20b can be selectively connected, or the first interface 20a can be selectively connected to at least one connection port 20b. Specifically, the first valve body 22 has multiple connection ports 20b. By selectively connecting at least two connection ports 20b or selectively connecting the first interface 20a to at least one connection port 20b, the flow direction of the heat exchange medium in the valve island assembly 20 can be changed, thereby controlling the compressor assembly 1, which is equipped with the valve island assembly 20, for cooling or heating.

[0061] In some embodiments, the first valve body 22 is a four-way valve, and the connecting port 20b at the bottom of the four-way valve is configured to have three ports.

[0062] It is worth mentioning that the first pipe 30 and the second pipe 40 are used to connect the valve body and the external structure of the valve island assembly 20, or to connect the valve island body 21 and the external structure of the valve island assembly 20, according to some embodiments of this utility model, such as Figures 1-2As shown, the valve island assembly 20 also includes a connecting pipe 23, which is adapted to connect the communication port 20b of the first valve body 22 with the flow channel. The connecting pipe 23 does not protrude from the top pipe section 31 in the height direction. That is, the connecting pipe 23 is used to connect the first valve body 22 and the valve island body 21, and the connecting pipe 23 and the communication port 20b are arranged in a one-to-one correspondence. By designing the connecting pipe 23 not to protrude from the top pipe section 31 in the height direction, at least one pipe in the pipeline of the valve island assembly 20 itself does not protrude from the top pipe section 31 in the height direction, so that the placement space of the connecting pipe 23 and the top pipe section 31 overlaps in the height direction, reducing the space occupied by the connecting pipe 23 on the second side 202, improving the integration of the compressor assembly 1, and reducing the space occupied by the compressor assembly 1.

[0063] Furthermore, the dimension of the connecting pipe 23 in the height direction is 'a', and it satisfies: a ≤ 420 mm. Here, the first valve body 22 and the valve island body 21 are connected by the connecting pipe 23. Both ends of the connecting pipe 23 are connected to the first valve body 22 and the valve island body 21, respectively. One end of the connecting pipe 23 can be inserted into the corresponding interface of the first valve body 22, and the other end of the connecting pipe 23 can be inserted into the corresponding interface of the valve island body 21. The distance between the interface end face of the connecting pipe 23 and the first valve body 22 and the interface end face of the connecting pipe 23 and the valve island body 21 is L (not shown in the figure).

[0064] The dimension 'a' of the connecting pipe 23 in the height direction refers to the situation where the axis of the connecting pipe 23 is simultaneously perpendicular to both the interface end face between the connecting pipe 23 and the first valve body 22 and the interface end face between the connecting pipe 23 and the valve island body 21. Figure 3 As shown, the extension direction of the connecting pipe 23 is consistent with the height direction. The distance L between the two interface end faces is the dimension a of the connecting pipe 23 in the height direction. If the angle between the axis of the connecting pipe 23 and any of the interface end faces is not equal to 90°, the extension direction of the connecting pipe 23 intersects with the height direction. In this case, the distance L 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 a of the connecting pipe 23 in the height direction.

[0065] To ensure that 'a' is no greater than 420mm, and to avoid the connecting pipe 23 and the first valve body 22 occupying too much space in the height direction, the connecting pipe 23 and the first valve body 22 can be limited to a height range that does not protrude beyond the top pipe section 31 in the height direction. This allows the connecting pipe 23 and the first valve body 22 to overlap with the top pipe section 31 in the height direction, reducing the space occupied by the connecting pipe 23 and the first valve body 22 on the second side 202, improving the integration of the compressor assembly 1, and reducing the space occupied by the compressor assembly 1.

[0066] According to some embodiments of this utility model, such as Figure 1 As shown, the top pipe section 31 and the valve island body 21 are spaced apart in the height direction to define an arrangement space between the top pipe section 31 and the valve island body 21; the valve body includes a second valve body 24, which is located on the second side 202 and disposed in the arrangement space.

[0067] The valve body includes a second valve body 24, which is located on the second side 202 and disposed in the arrangement space. The arrangement space defined between the top pipe section 31 and the valve island body 21 overlaps with the placement space of the top pipe section 31 in the height direction. By placing the second valve body 24 in the arrangement space, the placement space of the second valve body 24 overlaps with the placement space of the top pipe section 31 in the height direction. There is no need to reserve additional placement space for the second valve body 24 in the height direction, which can reduce the space required for the second valve body 24 in the height direction, improve the integration of the compressor assembly 1, and reduce the space occupied by the compressor assembly 1.

[0068] Furthermore, the maximum distance between the second valve body 24 and the valve island body 21 in the height direction is less than the maximum distance between the top pipe section 31 and the valve island body 21 in the height direction. At this time, the second valve body 24 does not protrude from the top pipe section 31 in the height direction, which can reduce the space required for the second valve body 24 in the height direction and improve the integration of the compressor assembly 1, thereby reducing the space occupied by the compressor assembly 1.

[0069] Furthermore, in such Figures 1-2 In the illustrated embodiment, the second valve body 24 is an expansion valve adapted to control the opening of the flow channel. The distance between the top surface of the expansion valve and the valve island body 21 in the height direction is b, satisfying: b≤540mm. As mentioned above, the valve body may also include an expansion valve, which is generally an electronic expansion valve. It precisely controls the flow rate of the heat exchange medium entering other structures of the compressor assembly 1 by controlling the opening of the corresponding flow channel, thereby achieving high efficiency, energy saving, and precise temperature control.

[0070] Here, the distance b between the top surface of the expansion valve and the valve island body 21 in the height direction refers to the distance between the interface end face of the corresponding interface of the valve island body 21 and the top surface of the expansion valve in the height direction after the expansion valve is connected to the corresponding interface of the valve island body 21. This distance b is not greater than 540mm to avoid the expansion valve occupying too much space in the height direction. The expansion valve can be limited to a height range that does not protrude from the top pipe section 31, so that the placement space of the expansion valve and the top pipe section 31 overlaps in the height direction, reducing the space occupied by the expansion valve on the second side 202, improving the integration of the compressor assembly 1, and reducing the space occupied by the compressor assembly 1.

[0071] According to some embodiments of this utility model, such as Figure 4As shown, the compressor assembly 1 also includes a connecting pipe 28, which is adapted to connect the second valve body 24 and the valve island body 21. The dimension of the connecting pipe 28 in the height direction is e, and satisfies: e≤450mm.

[0072] Here, the expansion valve and the valve island body 21 are connected by a connecting pipe 28. Both ends of the connecting pipe 28 are connected to the expansion valve and the valve island body 21, respectively. One end of the connecting pipe 28 can be inserted into the corresponding port of the expansion valve, and the other end of the connecting pipe 28 can be inserted into the corresponding port of the valve island body 21. The distance between the interface end face of the connecting pipe 28 and the expansion valve, and between the interface end face of the connecting pipe 28 and the valve island body 21, is L0 (not shown in the figure).

[0073] The dimension 'e' of the connecting pipe 28 in the height direction refers to the condition where the axis of the connecting pipe 28 is perpendicular to both the interface end face of the connecting pipe 28 and the interface end face of the connecting pipe 28 and the valve island body 21. Figure 4 As shown, the extension direction of the connecting pipe 28 is consistent with the height direction. The distance between the two interface end faces in the height direction is e, which satisfies that e is not greater than 450mm. This further avoids the expansion valve occupying too much space in the height direction. The expansion valve can be limited to the height range of the top pipe section 31 without protruding. This allows the expansion valve and the top pipe section 31 to overlap in the height direction, reducing the space occupied by the expansion valve on the second side 202, improving the integration of the compressor assembly 1, and reducing the space occupied by the compressor assembly 1.

[0074] It is worth mentioning that when connecting the aforementioned connecting pipe 28 and connecting pipe 23 to the valve island body interface and the valve body interface, they are usually inserted into the corresponding interfaces of the valve island body 21 and the valve body, and then welded to complete the connection. Since the connecting pipe 28, connecting pipe 23, valve island body interface and valve body interface can be made of the same or different materials, such as the connecting pipe 28 or connecting pipe 23 being made of stainless steel and the first valve body interface being made of copper, a copper sleeve will be used at the copper interface in the welding process, and the copper sleeve will be welded to the stainless steel. In this case, the copper sleeve is part of the size of the connecting pipe or connecting pipe, and the same applies in other cases.

[0075] 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 connecting pipe 28 and the expansion valve and the interface end face of the connecting pipe 28 and the valve island body 21 is the dimension e of the connecting pipe 28 in the height direction. The dimension e of the connecting pipe 28 in the height direction can be measured with the above two interface end faces as a reference.

[0076] The distance in the height direction between the interface end face of the connecting pipe 23 and the first valve body 22 and the interface end face of the connecting pipe 23 and the valve island body 21 is the dimension a of the connecting pipe 23 in the height direction. The dimension a of the connecting pipe 23 in the height direction can be measured with the above two interface end faces as a reference.

[0077] According to some embodiments of this utility model, the compressor body 10 also has a return air port; such as Figures 1-2 As shown, the compressor assembly 1 also includes a gas-liquid separator 50, which is located on the same side of the valve island assembly 20 in the height direction as the compressor body 10 and has a separation inlet and a separation outlet. The separation inlet is connected to the second interface through the second pipeline 40, and the separation outlet is connected to the return gas port. In the height direction, the projection of the valve island assembly 20 overlaps with the projection of the gas-liquid separator 50 and / or the projection of the compressor body 10.

[0078] Specifically, the gas-liquid separator 50 is generally installed on the return gas path of the compressor body 10. The gas-liquid separator 50 has a separation inlet and a separation outlet. The separation inlet is connected to a second interface of the valve island assembly 20 via a second pipeline 40, and the separation outlet is connected to the return gas port. This separates the gaseous heat exchange medium flowing from the valve island assembly 21 to the return gas port of the compressor body 10 from the liquid heat exchange medium. Generally, the gas-liquid separator 50 reduces the flow rate and uses gravity to separate and temporarily store any liquid heat exchange medium that may be mixed in with the gaseous heat exchange medium. The gaseous heat exchange medium separated by the gas-liquid separator 50 is transported to the compressor body 10 through the return gas port. The liquid heat exchange medium in the gas-liquid separator 50 is slowly vaporized and then transported to the compressor body 10 through the return gas port. The gas-liquid separator 50 ensures that only pure gaseous heat exchange medium enters the compressor body 10, preventing liquid slugging and ensuring its safety.

[0079] More specifically, the gas-liquid separator 50 and the compressor body 10 are located on the same side of the valve island assembly 20 in the height direction, so that the placement space of the gas-liquid separator 50 and the compressor body 10 overlaps in the height direction, thereby reducing the space occupied by the compressor assembly 1 in the height direction.

[0080] Furthermore, in the height direction, the projection of the valve island assembly 20 partially overlaps with the projection of the gas-liquid separator 50 and / or the projection of the compressor body 10. See reference... Figures 1-2The projection of valve island assembly 20 in the height direction is also the projection of valve island assembly 20 on the horizontal plane. Similarly, the projections of gas-liquid separator 50 and compressor body 10 in the height direction are also the projections on the horizontal plane. The projection of valve island assembly 20 on the horizontal plane overlaps with the projection of at least one of gas-liquid separator 50 and compressor body 10 on the horizontal plane, making the arrangement of compressor assembly 1 more compact in the horizontal direction, thereby reducing the space occupied by compressor assembly 1 in the horizontal direction.

[0081] Of course, the projection of the valve island body 21 in the height direction can also overlap with the projection of other structures in the height direction of the compressor assembly 1, which can also achieve the effect of compact arrangement of the compressor assembly 1 in the horizontal direction and reduce the space occupied by the compressor assembly 1 in the horizontal direction.

[0082] In some embodiments of this utility model, the compressor assembly 1 includes at least a compressor body 10, a valve island assembly 20, a gas-liquid separator 50, and multiple pipelines connecting the valve island assembly 20 to other structures. The compressor body 10 has an exhaust port and a return port, and the valve island assembly 20 includes a valve island body 21, connecting pipelines 23, and multiple valve bodies. A flow channel is formed inside the valve island body 21. With the valve island body 21 as the boundary, the compressor body 10 and the gas-liquid separator 50 are located on the first side 201 of the valve island body 21 in the height direction. Among the multiple pipelines connecting the valve island assembly 20 to other structures, there is a first pipeline 30. Among the multiple valve bodies, there is a reversing valve. The reversing valve is provided with a first interface 20a. The first pipeline 30 is connected to the exhaust port and the first interface 20a. The reversing valve is also provided with a connecting port 20b. The connecting pipeline 23 connects the connecting port 20b of the reversing valve to the flow channel. The first pipeline 30 has a top pipe section 31. The top pipe section 31 is located on the second side 202 of the valve island body 21 in the height direction. The connecting pipeline 23 and the reversing valve are also provided on the second side 202 of the valve island body 21 in the height direction, and do not protrude from the top pipe section 31 in the height direction. The top pipe section 31 and the valve island body 21 are spaced apart in the height direction to define an arrangement space between them. An expansion valve among the plurality of valve bodies is located on the second side 202 of the valve island body 21 in the height direction and within this arrangement space. At least a portion of the second pipe 40 extends toward the first side 201 of the valve island body 21, so that the second pipe 40 overlaps with the placement space of the compressor body 10 in the height direction, reducing the space occupied by the second pipe 40 on the second side 202. Alternatively, at least a portion of the second pipe 40 extends toward the second side 202 and is located between the top pipe section 31 and the valve island body 21, so that the second pipe 40 overlaps with the placement space of the top pipe section 31 in the height direction, reducing the space occupied by the second pipe 40 on the second side 202.

[0083] In the compressor assembly 1 designed in this utility model, by designing the relative positions of the compressor body 10, valve island assembly 20, gas-liquid separator 50, and multiple pipelines connecting the valve island assembly 20 to other structures, the overall space occupied by the compressor assembly 1 in the vertical and horizontal directions can be reduced as much as possible, the integration of the compressor assembly 1 can be improved, the pipeline layout of the compressor assembly 1 can be optimized, and interference with the layout of external structures can be avoided. This facilitates the production, installation, and maintenance of the compressor assembly 1 and is conducive to the miniaturization and weight reduction of products equipped with the compressor assembly 1.

[0084] exist Figures 1-2 In the illustrated embodiment, the valve island assembly 20 houses the electronic expansion valve, plate heat exchanger, four-way valve, solenoid valve 27, valve plate 210, oil separator 60, high-pressure valve 25, and low-pressure valve 26 on the valve island body 21. The valve island body 21, electronic expansion valve, plate heat exchanger, four-way valve, solenoid valve 27, valve plate 210, oil separator 60, gas-liquid separator 50, high-pressure valve 25, low-pressure valve 26, and compressor body 10 are directly connected or indirectly connected via pipelines. Multiple components of the compressor assembly 1 are connected together through the valve island body 21. The valve island assembly 20 is fixed to the gas-liquid separator 50. A valve island support 80 is located below the valve island assembly 20. The valve island support 80 is fixed to the gas-liquid separator 50 by welding, or by screws or rivets. The valve plate 210 is fixed to the valve island body 21. Positioning holes and screw holes are provided on both sides of the valve plate 210. The valve plate 210 is fixed to the valve island body 21 by screws. The valve plate 210 also has fixing screw holes to connect the valve island assembly 20 to the bracket, while the bracket does not contact the valve plate 210. Fixing screw holes are also provided on both sides of the bracket to connect to the structural components on both sides of the compressor body 10, thereby supporting the valve island assembly 20 within the housing of the air conditioner 1000.

[0085] Here, the electronic expansion valve, plate heat exchanger, four-way valve, solenoid valve 27, oil separator 60, gas-liquid separator 50, high-pressure valve 25, and low-pressure valve 26 are integrated together through the valve island body 21. The welding between the integrated components can be completed in pre-assembly and leak-tested, saving assembly welding time and reducing the probability of leakage at the assembly weld points. Furthermore, the various components of the compressor assembly 1 are also connected through the valve island body 21, which can reduce the overall pipeline length of the compressor assembly 1 and reduce pipe resistance and pressure loss. At the same time, each component is fixed on the valve island body 21, and then the valve island body 21 is fixed on the gas-liquid separator 50. The above operations can realize the pre-assembly of the compressor assembly 1. After the compressor assembly 1 is pre-assembled, it is fixed together on the base plate 2 of the air conditioner 1000 housing, which can save assembly time and installation personnel manpower. One end of the valve island body 21 is fixed to the gas-liquid separator 50, and the other end is connected to the structural components on both sides via a bracket. This prevents vibrations from the compressor body 10 and pipelines from being transmitted to the valve island body 21, causing it to vibrate and shake. The valve plate 210 is directly connected to the valve island body 21, without connecting to any other structural components. This prevents vibrations from the valve plate 210 from being transmitted to other structural components, reducing vibration and noise. Furthermore, the valve plate 210 does not need to be connected to other parts, improving overall assembly efficiency. The connections between the various components of the compressor assembly 1 and the pipelines can be pre-assembled and welded, followed by leak testing. This reduces the number of weld points in the final assembly, decreasing the leakage rate and improving overall assembly efficiency. Since the various components of the compressor assembly 1 are fixed to the valve island body 21, the support provided by the valve island body 21 during transportation and use enhances the overall structural reliability.

[0086] The air conditioner 1000 according to this utility model is briefly described below.

[0087] like Figure 5 As shown, the air conditioner 1000 according to the present invention includes the compressor assembly 1 described in any of the above embodiments. Since the air conditioner 1000 according to the present invention is provided with the compressor assembly 1 of the above embodiments, the air conditioner 1000 is more compact and lightweight, and is easier to maintain.

[0088] In some embodiments, the air conditioner 1000 has a housing with an installation space inside. The compressor assembly 1 and structural components of the air conditioner 1000, such as the fan and electrical control box, are jointly disposed in the installation space. The top of the housing is a top plate and the bottom is a bottom plate 2. The compressor assembly 1 is fixedly disposed on the bottom plate 2 of the housing. By increasing the integration of the compressor assembly 1, it is easier to arrange other structural components of the air conditioner 1000. It is also suitable for miniaturizing and lightening the air conditioner 1000. By designing the structure of the valve island assembly 20, multiple components of the compressor body 10 are connected together through the valve island assembly 20 to form a complete flow path suitable for the flow of heat exchange medium. The valve island assembly 20 is fixed inside the housing, which facilitates the installation and maintenance of the valve island assembly 20.

[0089] Furthermore, among the multiple pipes that connect the valve island assembly 20 to other structures, the top pipe section 31 of the first pipe 30 protrudes beyond the other pipes in the height direction to reserve space at the top of the valve island assembly 20, which facilitates the installation and arrangement of other structures of the air conditioner 1000.

[0090] In some embodiments, the maximum distance in the height direction between the top pipe section 31 and the bottom plate 2 is c, and the maximum distance in the height direction between the bottom plate 2 and the top plate is d, satisfying: c ≤ 0.9d. Here, the maximum distance in the height direction between the top pipe section 31 and the bottom plate 2 refers to the maximum distance between the upper surface of the bottom plate 2 and the end face of the top pipe section 31 away from the bottom plate 2; the maximum distance in the height direction between the bottom plate 2 and the top plate refers to the maximum distance between the upper surface of the bottom plate 2 and the lower surface of the top plate. Further, the distance dc between the top pipe section 31 and the top plate is ≥ 6cm, and can be 6cm, 8cm, 10cm, 12cm, 15cm, 20cm, etc., to reserve space at the top of the valve island assembly 20, facilitating the installation and arrangement of other structures of the air conditioner 1000.

[0091] In some embodiments, the top pipe segment 31 is bent to define a clearance space 31a at the top to allow for the installation of other structures within the reserved space at the top of the valve island assembly 20, while also preventing collisions with other structures within the reserved space under vibration. Furthermore, the bent portion of the top pipe segment 31 has a certain degree of elasticity to cushion other structures within the reserved space.

[0092] In some embodiments, the compressor assembly 1 is further provided with a refrigerant heat dissipation pipe 90, which protrudes from the first pipe 30 in the height direction.

[0093] In summary, the compressor assembly 1 designed according to this utility model integrates a compressor body 10, a valve island assembly 20, and pipelines connected to the valve island assembly 20. The pipelines connected to the valve island assembly 20 include at least a first pipeline 30 and a second pipeline 40. The second pipeline 40 is designed not to protrude from the top pipe section 31 in the height direction, so that the second pipeline 40 overlaps with the placement space of other structures of the compressor assembly 1 in the height direction. This eliminates the need to reserve additional placement space for the second pipeline 40 in the height direction, reduces the space required for the second pipeline 40 in the height direction, improves the integration of the compressor assembly 1, reduces the space occupied by the compressor assembly 1, and avoids the second pipeline 40 interfering with the arrangement of other structures of the compressor assembly 1 or structures outside the compressor assembly 1. By limiting the placement positions of the first pipeline 30 and the second pipeline 40, the pipeline layout of the compressor assembly 1 can be optimized, which facilitates the production, installation, and maintenance of the compressor assembly 1 and is conducive to the miniaturization and weight reduction of products equipped with this compressor assembly 1.
