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

[0045] The following is for reference. Figures 1-6 This invention describes an air conditioner according to an embodiment of the present invention.

[0046] Reference Figure 1 , Figure 2 and Figure 5 According to an embodiment of the present invention, the air conditioner 100 includes: a housing 1, an integrated valve island 2, a support member, a low-pressure valve 5, and a high-pressure valve 6. The integrated valve island 2 is provided with a refrigerant flow channel; the support member is disposed on the housing 1 and is fixedly supported by the integrated valve island 2 through a connecting pipe 22; the low-pressure valve 5 and the high-pressure valve 6 are respectively connected to the refrigerant flow channel.

[0047] In this context, air conditioner 100 refers to an air conditioner, which 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 velocity of the air in a room (or enclosed space, area) by generating cold 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 of an air conditioner.

[0048] 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, in which various structures required for the operation of the air conditioner 100 can be installed. The casing 1 can protect the various structures and also provide installation points for the various structures inside the air conditioner 100, ensuring installation reliability. A partition 12 can be provided inside the air conditioner 100. The partition 12 can be connected to the casing 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.

[0049] The compressor assembly can be installed inside the casing 1. The compressor assembly includes a compressor 101 and multiple refrigerant piping components. The multiple refrigerant piping components can be equipped with a four-way valve 7, an electronic expansion valve 8, a plate heat exchanger 102, a gas-liquid separator 4, an oil separator 103, a solenoid valve, a high-pressure valve 6, and a low-pressure valve 5. The multiple refrigerant piping components can be connected to the compressor 101 to form a refrigerant circuit to ensure the reliable operation of the air conditioner 100.

[0050] Furthermore, the air conditioner 100 is also provided with an integrated valve island 2, which defines a refrigerant flow path. At least two of the plurality of refrigerant piping components and compressor 101 (e.g., high-pressure valve 6 and low-pressure valve 5) can be connected to the refrigerant flow path of the integrated valve island 2, and the plurality of refrigerant piping components can be connected to compressor 101 through the integrated valve island 2 to form a refrigerant circuit. In some preferred embodiments, all of the plurality of refrigerant piping components and compressor 101 are connected to the integrated valve island 2.

[0051] By setting up an integrated valve island, the length of refrigerant piping can be shortened, reducing the space occupied by multiple refrigerant piping lines. This improves integration, resulting in lighter weight and lower installation costs. At the same time, it reduces the number of connection points for multiple refrigerant piping lines, thereby reducing the risk of refrigerant and other media leakage and improving the reliability of the air conditioner 100.

[0052] In this embodiment of the utility model, the air conditioner 100 includes a support member, which is disposed on the housing 1 and the support member is fixedly supporting the integrated valve island 2 through the connecting pipe 22.

[0053] Among them, the support member refers to the structural member on or inside the housing 1 that serves to install and support other components located inside the housing 1. For example, the support member can be a side plate of the housing 1, which includes a top plate, a chassis, a front side plate, a rear side plate, a left side plate, and a right side plate. The support member can also be a partition plate 12, a heat exchanger side plate, a terminal block, an electrical control box mounting plate, a fan mounting bracket, or other brackets fixedly installed inside the housing. The support member can also be a functional component such as a gas-liquid separator 4, an oil separator 103, or a plate heat exchanger 102 fixedly installed inside the housing 1, as long as it can be used to support the integrated valve island 2. This application does not impose any restrictions on this.

[0054] Reference Figure 2 , Figure 3 and Figure 5 In this embodiment of the present invention, the integrated valve island 2 is connected to the support member via a connecting pipe 22. For example, the integrated valve island 2 and the connecting pipe 22 can be connected by welding, bolting, snap-fitting, and / or riveting, and the connecting pipe 22 and the support member can also be connected by welding, bolting, snap-fitting, and / or riveting.

[0055] According to the embodiment of this utility model, the air conditioner 100 can integrate the refrigerant circuit inside the air conditioner 100 through the integrated valve island 2, thereby improving weight reduction and reducing installation costs. 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. The integrated valve island 2 is fixedly connected to the support through the connecting pipe 22, which can improve the reliability of the fixed connection of the integrated valve island 2. When vibration is transmitted to the integrated valve island 2, it can also reduce the problem of shaking caused by vibration of the integrated valve island 2, ensuring the connection reliability and sealing performance between the integrated valve island 2 and the compressor and multiple refrigerant pipeline components, and improving the installation reliability of the integrated valve island 2.

[0056] In some embodiments, the support member includes at least one functional component selected from the following: gas-liquid separator 4, oil separator 103, and plate heat exchanger 102. In this embodiment, the support member fixes and supports the integrated valve island 2 via a connecting pipe 22, and is connected to the refrigerant flow channel via the connecting pipe 22.

[0057] In this embodiment of the utility model, the connecting pipe 22 can not only be used to fix and support the integrated valve island 2 to the support member, but also to connect the support member with the refrigerant flow channel in the integrated valve island 2, which simplifies the internal structure of the air conditioner, is conducive to the lightweighting of the air conditioner 0, and reduces the cost of the air conditioner.

[0058] In some specific embodiments, the support includes a gas-liquid separator 4, which can be connected to the bottom of the housing 1 by means of connectors or welding. The gas-liquid separator 4 is fixedly supported by the integrated valve island 2 through the connecting pipe 22 and is connected to the refrigerant flow channel through the connecting pipe 22.

[0059] In this embodiment of the utility model, the integrated valve island 2 is supported by the gas-liquid separator 4, which effectively improves the stability of the integrated valve island 2, reduces the problem of shaking caused by vibration of the integrated valve island 2, ensures the reliability of the connection and sealing performance between the integrated valve island 2 and the compressor and multiple refrigerant pipeline components, and improves the installation reliability of the integrated valve island 2.

[0060] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments, the gas-liquid separator 4 includes an inlet end 41 and an outlet end 42. The inlet end 41 is connected to the integrated valve island 2 through a first pipe 411, which is formed as a connecting pipe 22.

[0061] In this embodiment of the utility model, the first pipe 411 can not only be used to connect the air inlet 41 to the integrated valve island 2, but also to fix the integrated valve island 2 to the gas-liquid separator 4. There is no need to set up a separate structural component specifically for connecting the integrated valve island 2 and the gas-liquid separator 4, which simplifies the internal structure of the air conditioner 100, is conducive to the lightweighting of the air conditioner 100, and reduces the cost of the air conditioner 100.

[0062] In some other embodiments, the gas-liquid separator 4 includes an inlet end 41 and an outlet end 42. The outlet end 42 is connected to the integrated valve island 2 through a second pipe 421, which is formed as a connecting pipe 22.

[0063] In this embodiment of the utility model, the second pipe 421 can not only be used to connect the exhaust end 42 to the integrated valve island 2, but also to fix the integrated valve island 2 to the gas-liquid separator 4. There is no need to set up additional structural components specifically for connecting the integrated valve island 2 and the gas-liquid separator 4, which simplifies the internal structure of the air conditioner 100, is conducive to the lightweighting of the air conditioner 100, and reduces the cost of the air conditioner 100.

[0064] In some other embodiments, the gas-liquid separator 4 includes an inlet end 41 and an outlet end 42. The inlet end 41 is connected to the integrated valve island 2 via a first pipe 411, which is formed as a connecting pipe 22. The outlet end 42 is connected to the integrated valve island 2 via a second pipe 421, which is also formed as a connecting pipe 22.

[0065] In other words, in this embodiment of the present invention, the integrated valve island 2 is fixedly connected to the gas-liquid separator 4 through the first pipe 411 and the second pipe 421, which further improves the stability of the connection between the integrated valve island 2 and the gas-liquid separator 4.

[0066] In some embodiments, the connecting pipe 22 is integrally connected to the gas-liquid separator 4 and supports the integrated valve island 2. In other embodiments, the connecting pipe 22 may also be integrally connected to the integrated valve island 2 and supported by the gas-liquid separator 4. As long as the integrated valve island 2 can be fixedly connected to the gas-liquid separator 4 through the connecting pipe 22, this utility model is not limited in this respect.

[0067] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the gas-liquid separator 4 extends in a vertical direction, and in a projection plane perpendicular to the vertical direction, the integrated valve island 2 overlaps at least partially with the gas-liquid separator 4, the integrated valve island 2 including a first region located in the overlapping portion.

[0068] The above technical solution can improve the utilization rate of the internal space of the casing 1, thereby reducing the space occupied by the air conditioner 100 and improving the lightweight of the air conditioner 100.

[0069] In some further embodiments, the connecting pipe 22 is located in the first region in the orthographic projection plane perpendicular to the vertical direction.

[0070] For example, the top wall of the gas-liquid separator 4 is provided with an inlet end 41 and an outlet end 42. The inlet end 41 is connected to the integrated valve island 2 through a first pipe 411, which forms a connecting pipe 22. The outlet end 42 is connected to the integrated valve island 2 through a second pipe 421, which also forms a connecting pipe 22. The connecting pipe 22 is integrally connected to the gas-liquid separator 4 and supports the integrated valve island 2. The connecting pipe 22 is located in the first region.

[0071] The above technical solution further improves the utilization rate of the internal space of the casing 1, thereby reducing the space occupied by the air conditioner 100 and improving the lightweight of the air conditioner 100.

[0072] It should be understood that in other embodiments, the connecting pipe 22 may also be used for fixing the integrated valve island 2 and the gas-liquid separator 4 through other structural components, and the present invention does not limit this.

[0073] In some embodiments, the connecting pipe 22 is made of stainless steel. This improves the structural strength and service life of the connecting pipe 22.

[0074] In some embodiments, at least a portion of the integrated valve island 2 is made of stainless steel. This ensures the structural strength of the integrated valve island 2, thereby improving the reliability of its use. It should be understood that in other embodiments, the integrated valve island 2 may also be made of other materials such as carbon steel or aluminum alloy, and this application does not impose any limitations on this.

[0075] In some embodiments, the integrated valve island 2 is also connected to a low-pressure valve 5 and / or a high-pressure valve 6. The low-pressure valve 5 and / or the high-pressure valve 6 are fixedly mounted on the housing 1 via a valve plate 3, thereby allowing the integrated valve island 2 to be fixedly installed inside the housing 1 via the low-pressure valve 5 and / or the high-pressure valve 6. In this embodiment of the present invention, the integrated valve island 2 is not only installed and fixed by a support member, but also by the low-pressure valve 5 and / or the high-pressure valve 6, effectively improving the stability of the integrated valve island 2 installation.

[0076] Reference Figure 3 , Figure 4 and Figure 5 In some specific embodiments, the low-pressure valve 5 is fixedly installed on the valve plate 3, and the low-pressure valve 5 is connected to the refrigerant flow channel through the third pipe 51, which supports the integrated valve island 2; the high-pressure valve 6 is fixedly installed on the valve plate 3, and the high-pressure valve 6 is connected to the refrigerant flow channel through the fourth pipe 61, which supports the integrated valve island 2.

[0077] In this embodiment of the invention, both the low-pressure valve 5 and the high-pressure valve 6 are fixedly mounted on the valve plate 3. The third pipe 51 not only connects the low-pressure valve 5 to the refrigerant flow channel but also supports the integrated valve island 2, improving its stability. The fourth pipe 61 not only connects the low-pressure valve 5 to the refrigerant flow channel but also supports the integrated valve island 2, further enhancing its stability. Furthermore, there is no need for additional structural components specifically designed to connect the integrated valve island 2, the low-pressure valve 5, and the high-pressure valve 6, simplifying the internal structure of the air conditioner 100, promoting its lightweight design, and reducing its cost.

[0078] It should be understood that in other embodiments, the integrated valve island 2 may also be fixedly connected to the low-pressure valve 5 and / or the high-pressure valve 6 through other structural components, or it may be fixedly connected to the valve plate 3 through other structural components to indirectly connect to the low-pressure valve 5 and / or the high-pressure valve 6. This utility model does not limit this.

[0079] In some further embodiments, the low-pressure valve 5 and the high-pressure valve 6 are located on the side of the valve plate 3 opposite to the integrated valve island 2, and the third pipe 51 and the fourth pipe 61 pass through the valve plate 3. The low-pressure valve 5 and the high-pressure valve 6 can be connected to the valve plate 3 by means of connectors or welding, etc. The connectors can be bolts, etc., resulting in a simple structure, convenient installation, and low installation cost.

[0080] In this embodiment of the present invention, the low-pressure valve 5 and the high-pressure valve 6 are located on the side of the valve plate 3 away from the integrated valve island 2, which can reduce the distance between the valve plate 3 and the integrated valve island 2, which is beneficial to improve the utilization rate of the internal space of the housing 1, thereby reducing the space occupied by the air conditioner 100 and improving the lightweight of the air conditioner 100.

[0081] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the housing 1 includes an outer shell 11 and a middle partition 12. The middle partition 12 is fixedly disposed inside the outer shell 11 and divides the internal space of the outer shell 11 into a first cavity 13 and a second cavity 14. The first cavity 13 is used to house at least the compressor 101, the integrated valve island 2, the gas-liquid separator 4, the low-pressure valve 5, the high-pressure valve 6, and the valve plate 3. The second cavity is used to house at least the fan. At least a portion of the valve plate 3 extends along a first direction, and both ends of the valve plate 3 are fixedly connected to the middle partition 12 and the outer shell 11, respectively. The first direction is perpendicular to the vertical direction.

[0082] In other words, the first chamber 13 is the compressor chamber, and the second chamber 14 is the fan chamber. If the compressor 101 and the fan are in the same chamber, the noise from the compressor 101 and the fan will overlap and resonate, resulting in a louder volume when propagated outwards. The high temperature of the compressor 101 may heat the cold air drawn in by the fan, while the airflow from the fan may also interfere with the heat exchange rhythm around the compressor 101. The compressor 101 requires a stable high-temperature environment and low vibration interference, while the fan requires efficient airflow and low noise propagation. The separate chamber design allows both to operate in their respective optimal environments, ultimately achieving a comprehensive improvement in noise reduction, efficiency, and durability.

[0083] High-pressure valve 6 and low-pressure valve 5 are key nodes in the refrigerant circulation of air conditioner 100. High-pressure valve 6 connects the discharge end of compressor 101 to the condenser, and low-pressure valve 5 connects the evaporator to the suction end of compressor 101. Both valves must withstand the high pressure of the refrigerant and the high-frequency vibration of compressor 101 during operation. The design of connecting the valve plate 3 to the partition plate 12 and the outer casing 11 at both ends can improve the overall rigidity through double-support fixation.

[0084] In some embodiments, in the second direction, the valve plate 3 is located on the side of the integrated valve island 2 away from the gas-liquid separator 4, and the first direction, the second direction and the vertical direction are perpendicular to each other.

[0085] The above technical solution makes full use of the space inside the first cavity 13, thereby reducing the space occupied by the air conditioner 100 and improving the lightweight of the air conditioner 100.

[0086] Reference Figure 4 , Figure 5 and Figure 6 In some specific embodiments, the valve plate 3 includes: a main body 31, a first fixing part 32 and a second fixing part 33. The main body 31 extends along a first direction, and the high-pressure valve 6 and / or the low-pressure valve 5 are fixed to the main body 31. In the first direction, the two ends of the main body 31 are respectively provided with a first fixing part 32 and a second fixing part 33. The first fixing part 32 intersects with the main body 31, and the second fixing part 33 intersects with the main body 31. The first fixing part 32 is fixed to the middle partition 12, and the second fixing part 33 is fixed to the outer shell 11.

[0087] The first fixing part 32 intersects with the main body part 31, meaning that the first fixing part 32 extends at an angle relative to the main body part 31. This allows the first fixing part 32 to avoid other components inside the housing 1 and facilitates the connection between the first fixing part 32 and the partition plate 12, thereby improving the assembly efficiency of the air conditioner 100. The second fixing part 33 intersects with the main body part 31, meaning that the second fixing part 33 is arranged at an angle relative to the main body part 31. This facilitates the connection between the second fixing part 33 and the outer casing 11, further improving the assembly efficiency of the air conditioner 100.

[0088] In some specific embodiments, the second fixing part 33 is fitted to the outer shell 11 to facilitate the connection between the second fixing part 33 and the outer shell 11.

[0089] It should be noted that the second fixing part 33 can be connected to the outer shell 11 by means of connectors or welding. The connectors can be bolts, etc., which are simple in structure, convenient to install, and have low installation cost.

[0090] In some specific embodiments, the front end of the partition plate 12 is provided with a flange 121, and a portion of the first fixing part 32 is stacked and fixedly connected with the flange 121 to facilitate the connection between the first fixing part 32 and the partition plate 12.

[0091] It should be noted that the first fixing part 32 can be connected to the middle partition plate 12 by means of connectors or welding. The connectors can be bolts, etc., which are simple in structure, convenient to install, and have low installation cost.

[0092] In some embodiments, the main body 31 is provided with a reinforcing rib 34 extending to at least one of the first fixing part 32 and the second fixing part 33, which effectively improves the structural strength of the valve plate 3, ensures the stability of the installation of the high pressure valve 6 and / or the low pressure valve 5, and thus ensures the stability of the installation of the integrated valve island 2.

[0093] In some specific embodiments, the main body 31 is provided with a plurality of reinforcing ribs 34, which are spaced apart in the vertical direction, and some of the reinforcing ribs 34 extend to the first fixing part 32 along the first direction. It should be understood that the reinforcing ribs 34 can also be arranged in other ways, and the present invention does not limit this.

[0094] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments, the integrated valve island 2 includes a first raft plate 21, the first raft plate 21 defining a first surface a, and a plurality of valve body connectors 211 provided on the first surface a, the valve body connectors 211 being used to connect valve bodies.

[0095] Multiple valve body connectors 211 are provided on the first surface a of the first raft plate 21. The multiple valve body connectors 211 are used to connect valve bodies (such as four-way valve 7, low-pressure valve 5, high-pressure valve 6, and one-way solenoid valve 9, etc.). The multiple valve bodies can be arranged compactly to reduce the length of the connecting pipeline, which can reduce pipe resistance and pressure loss, thereby reducing heat loss, and can also reduce costs, improve space occupation, and reduce layout difficulty.

[0096] It is understood that in some embodiments, the integrated valve island 2 may include at least one support plate and a plurality of valve body connectors 211 disposed on the support plate. The support plate may have through holes, and the valve body connectors 211 may be constructed as flow channel block structures, i.e., the valve body connectors 211 may be constructed as a prism or cylinder structure, and a refrigerant flow channel may be formed inside it. Openings may be formed on the end face or side face, and these openings may be formed as inlet or outlet ends. The through holes are connected to the inlet or outlet ends. Furthermore, one valve body connector 211 may be configured to have one or more inlet ends or one or more outlet ends, so that each flow channel block structure has both an inlet end and an outlet end. This allows the inlet end of the valve body connector 211 to communicate with the corresponding component, and the outlet end to communicate with the corresponding valve body. Alternatively, adjacent valve body connectors 211 can be connected and connected to different components or different valve bodies respectively, to correspondingly define the series path segment (multiple components, valve bodies, etc. are connected in sequence), parallel path segment (with two or more branches, each branch is equipped with at least one component or valve body), or mixed path segment (including both series path segments and mixed path segments) in the refrigerant circuit, and define the "valve island" structure, such as: the inlet end is connected to the gas-liquid separator 4, oil separator 103 or compressor 101, and the outlet end is connected to the four-way valve 7, electronic expansion valve 8, etc., to form a complete refrigerant circuit, which can reduce the length of the connecting pipes, thereby reducing costs and improving space occupation. At the same time, it can reduce the flow resistance and pressure loss of the refrigerant circuit, reduce heat loss, and improve the efficiency of the refrigerant circuit.

[0097] In other embodiments, the integrated valve island 2 may include multiple support plates, and one or more cavities may be formed between adjacent support plates. The cavities may define refrigerant flow channels, and openings may be provided on the support plates to communicate with the cavities, thereby enabling communication between adjacent refrigerant flow channels. Furthermore, the openings on the two outermost support plates may be directly formed as valve body connectors 211, or protruding tubes may be further provided on the openings, with the protruding tubes forming valve body connectors 211.

[0098] Any one of the multiple support plates can be formed as the first raft plate 21.

[0099] Of course, it is understandable that the integrated valve island 2 may include two or more stacked support plates, with valve body connectors 211 provided between adjacent support plates, and multiple valve body structures may define multiple refrigerant channels, with any one of the multiple support plates forming a first raft plate 21; or the "valve island" structure may include two or more stacked support plates, with the interlayer cavities of adjacent support plates forming refrigerant channels, located on the two support plates on both sides of the thickness, or with valve body connectors 211 opened on the periphery of the thickness.

[0100] It should be noted that the integrated valve island 2 of this utility model can be constructed as a "single-layer valve island structure", including one or two support plates, one of which forms the first raft plate 21, or it can be constructed as a "multi-layer valve island structure", including three or more support plates, one of which forms the first raft plate 21.

[0101] In this way, by setting multiple valve body connectors on the first surface a of the first raft plate 21, the integrated valve island 2 can realize the connection between various valve bodies and different components (such as compressor 101, gas-liquid separator 4, oil separator 103, etc.) to form a complete refrigerant circuit. This can reduce the total length of the connecting pipes and the number of welding points, which can not only reduce the probability of refrigerant circuit leakage and improve the safety and reliability of air conditioner 100, but also reduce flow resistance and pressure loss, reduce heat loss of refrigerant circuit, and improve the efficiency of air conditioner 100.

[0102] In some embodiments, the valve body connector 211 includes at least one expansion valve connector, a four-way valve connector, a high-pressure valve connector 2112, and a low-pressure valve connector 2111. The expansion valve connector, the four-way valve connector, the low-pressure valve connector 2111, and the high-pressure valve connector 2112 are respectively used to connect the electronic expansion valve 8, the four-way valve 7, the high-pressure valve 6, and the low-pressure valve 5.

[0103] It should be noted that when the air conditioner 100 has an enthalpy-increasing branch, at least two electronic expansion valves 8 need to be installed in the refrigerant circuit, and the corresponding valve body connector 211 includes at least two expansion valve connectors. When the air conditioner 100 does not have an enthalpy-increasing branch, at least one electronic expansion valve 8 needs to be installed in the refrigerant circuit, and the corresponding valve body structure should include at least one expansion valve connector.

[0104] In some embodiments, the first raft plate 21 further defines a second surface b opposite to the first surface a, and a plate heat exchanger portion 212 is provided on the second surface b. The plate heat exchanger portion 212 is used to connect the plate heat exchanger 102, and the plate heat exchanger portion 212 is located on the second surface b and spaced apart from the gas-liquid separator 4.

[0105] The plate-mounted connector 212 is located on the second surface b. An opening is provided on the second surface b of the first raft plate 21, and a protruding tube is provided on the opening. The protruding tube forms the plate-mounted connector 212.

[0106] In this way, on the one hand, the plate heat exchanger joint 212 is located on the second surface b, which allows the plate heat exchanger joint 212 and the valve body joint 211 to be located on both sides of the first raft plate 21. Multiple valve bodies and plate heat exchangers 102 can be stacked in the height direction to further improve the space occupation of the integrated valve island 2 and improve compactness. It can also avoid the plate heat exchanger 102 from being inverted, thereby improving the heat exchange uniformity and heat exchange effect of the plate heat exchanger 102. On the other hand, the plate heat exchanger joint 212 can be separated from the gas-liquid separator 4, which can also reduce the probability of interference during the assembly of the plate heat exchanger 102 and the assembly of the integrated valve island 2 and the gas-liquid separator 4, and reduce the assembly difficulty.

[0107] Meanwhile, the electronic expansion valve 8, plate heat exchanger 102, four-way valve 7, one-way solenoid valve 9, oil separator 103, gas-liquid separator 4, high-pressure valve 6, low-pressure valve 5, etc. can be integrated and assembled first. After integration, the welding areas between each component can be pre-assembled and leak-tested, saving the overall assembly time, improving assembly efficiency, reducing production costs, and resulting in fewer overall weld points, a lower probability of leakage, and higher safety and reliability of the refrigerant circuit.

[0108] In some embodiments, the compressor 101 and the gas-liquid separator 4 are both located below the integrated valve island 2, the top of the gas-liquid separator 4 is connected to the integrated valve island 2, and the top of the compressor 101 is spaced apart from the integrated valve island 2 to jointly define a partition space.

[0109] Specifically, the integrated valve island 2 is installed on top of the gas-liquid separator 4, and the length of the compressor 101 is set to be less than the length of the gas-liquid separator 4, so that the compressor 101 and the gas-liquid separator 4 can both be set below the integrated valve island 2, and the vertical projection of the integrated valve island 2 overlaps at least partially with the vertical projection of the compressor 101, which can improve the utilization rate of the space inside the compressor 101 cavity, thereby reducing the space occupied by the air conditioner 100 and improving the lightweight of the air conditioner 100.
