[0043] An air conditioner according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0044] like Figures 1-8 As shown, the air conditioner according to an embodiment of the present invention includes a housing 1, a support member 3, a compressor 2, and a valve island assembly 5.

[0045] Specifically, compressor 2 is installed inside housing 1, support 3 is connected to housing 1, valve island assembly 5 is installed and supported on support 3, and valve island assembly 5 is connected to compressor 2 through multiple refrigerant pipeline components 4 to form a refrigerant circuit.

[0046] An air conditioner, also known as an air conditioning unit, consists of an indoor unit and an outdoor unit. It is a machine used to regulate air temperature changes in a space (usually enclosed). The function of an air conditioner is to adjust parameters such as temperature, humidity, cleanliness, and airflow within a room (or enclosed space / area) by producing cool or warm air to meet the requirements of human comfort or technological processes. In this embodiment, "air conditioner" may refer to the outdoor unit.

[0047] Specifically, the air conditioner is equipped with a casing 1, which is located on the outside of the air conditioner and thus provides support for it. An installation space is formed inside the casing 1, where various structures required for the operation of the air conditioner can be installed. The casing 1 can protect these structures and also provide installation points for the internal structures of the air conditioner, ensuring installation reliability. A partition can be installed inside the air conditioner, which can be connected to the casing 1 by means of connectors or welding. The connectors can be bolts, etc. The structure is simple, easy to install, and has low installation cost.

[0048] The compressor 2 can be installed inside the casing 1. Multiple refrigerant piping components 4 can be equipped with a four-way valve 43, an electronic expansion valve 44, a plate heat exchanger 41, an oil-gas separator 42, a solenoid valve 45, a high-pressure valve 46, and a low-pressure valve 47. The refrigerant piping components 4 can be connected to the compressor 2 to form a refrigerant circuit to ensure the reliability of the air conditioner operation.

[0049] Furthermore, such as Figures 1-2 and Figure 8 As shown, the air conditioner is also equipped with a valve island assembly 5, which includes a valve island body 51 and a valve island bracket 52. The valve island bracket 52 is connected to the support member 3. The valve island bracket 52 can be connected to the support member 3 by means of connectors or welding, and the valve island body 51 is connected to the valve island bracket 52, so that the valve island body 51 can be installed and supported on the support member 3 through the valve island bracket 52. The installation is convenient, and the valve island body 51 is only connected to the support member 3, which can isolate the vibration generated by the operation of other structures, thereby reducing the noise generated during the operation of the air conditioner and improving the user experience.

[0050] The support component 3 can be connected to the housing 1 by means of connectors or welding. The compressor 2 is spaced apart from the support component 3 and can also be connected to the housing 1 by connectors or welding. This allows the valve island assembly 5 to be fixedly installed in the housing 1 by the support component 3 alone. The valve island body 51 is supported on the end of the valve island bracket 52 away from the support component and spaced apart from the support component 3. The valve island body 51 and the compressor 2 are connected by multiple refrigerant pipeline components 4 to form a refrigerant circuit. This allows the valve island assembly 5 to be spaced apart from the compressor 2 and other structures to isolate the vibration generated by the compressor 2 and other structures during operation, thereby reducing the noise generated during air conditioner operation and improving the user experience.

[0051] Furthermore, such as Figure 8 As shown, if the support member 3 has a refrigerant pipeline or functions to act on the refrigerant, the support member 3 has a support member pipeline 32 connected to the pipeline interface on the valve island body 51. The support member pipeline 32 is connected to the pipeline and refrigerant pipeline component 4 of the valve island body 51.

[0052] The valve island bracket 52 is located above the support member 3, and the valve island body 51 is supported above the valve island bracket 52 and spaced apart from the support member 3; or the valve island bracket 52 is located on the side of the support member 3, and the valve island body 51 is connected to the valve island bracket 52 and spaced apart from the support member 3. The installation position of the valve island assembly 5 can be selected according to the layout of the internal space of the air conditioner to meet different usage requirements.

[0053] In addition, multiple refrigerant piping components 4 are connected to the valve island body 51, 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 conditioning.

[0054] In actual installation, the valve island support 52 can be made of carbon steel, stainless steel, aluminum alloy, etc., which can ensure the structural strength of the valve island support 52 and improve the installation reliability of the valve island body 51.

[0055] In this embodiment, apart from the valve island body 51, the support member 3, and the pipeline connecting the support member 3 and the valve island body 51, the valve island bracket 52 is used to connect and fix the valve island body 51 and the support member 3.

[0056] The valve island body 51 can be composed of multiple solenoid valves 45, which can share the same air intake source, but each has an independent output. Each solenoid valve 45 can open upon receiving an electronic control signal and send a pneumatic signal to drive other components. The valve island body 51 can control multiple valves and their signal processing, thereby achieving automatic fluid regulation and diversion. By controlling the opening and closing of the valves, the valve island body 51 can regulate fluid flow and pressure, thus improving the automation level of the air conditioning system.

[0057] In some embodiments, such as Figure 1 and Figure 6 As shown, multiple refrigerant piping components 4 include a plate heat exchanger 41, which is connected to the valve island body 51.

[0058] Specifically, multiple refrigerant piping components 4 are equipped with plate heat exchangers 41. The plate heat exchanger 41 is a high-efficiency heat exchanger made of stacked metal plates with a certain corrugated shape. Thin rectangular channels are formed between the various plates, through which heat exchange occurs. Figures 1-2 As shown, the plate heat exchanger 41 can be connected to the valve island body 51, so that the plate heat exchanger 41 can also be installed only on the valve island body 51, thereby isolating vibration.

[0059] According to the embodiment of the present invention, the air conditioner connects the valve island body 51 and the compressor 2 through multiple refrigerant pipeline components 4 to form a refrigerant circuit. The valve island bracket 52 is connected to the support member 3. The valve island body 51 is connected to the valve island bracket 52 and spaced apart from the support member 3. In this way, the sound radiation path generated by the vibration of the compressor 2 can be blocked through the valve island assembly 5, thereby reducing the noise generated during the operation of the air conditioner, improving the user experience, increasing integration, reducing space occupation, reducing production costs, improving lightweighting, reducing leakage risk, and improving reliability.

[0060] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the valve island support 52 is provided with a first sub-plate 521 and a second sub-plate 523. The first sub-plate 521 is connected to the support member 3, and the second sub-plate 523 is connected to the first sub-plate 521. The second sub-plate 523 is located above the first sub-plate 521 and spaced apart from the support member 3. The valve island body 51 is supported on the second sub-plate 523.

[0061] Thus, the support member 3 can support the valve island bracket 52 to improve the installation reliability of the valve island body 51, and the second sub-plate 523 can support the valve island body 51 to improve the installation reliability of the valve island body 51. It can also improve the utilization of space, thereby improving integration and weight reduction, and can reduce the setting of refrigerant pipelines to reduce installation costs.

[0062] Meanwhile, the valve island body 51 can be spaced apart from the support member 3, thereby blocking the vibration generated by the operation of other structures, reducing the noise generated during the operation of the air conditioner, and improving the user experience.

[0063] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the valve island bracket 52 also includes a connecting plate 522, which is used to connect the first sub-plate 521 and the second sub-plate 523.

[0064] Specifically, the valve island body 51 can be connected to the support member 3 via the valve island bracket 52, and as follows: Figures 2-3 As shown, the valve island support 52 is provided with a first sub-plate 521, a connecting plate 522 and a second sub-plate 523. The second sub-plate 523 is located above the first sub-plate 521 and spaced apart from the support member 3. The connecting plate 522 is used to connect the first sub-plate 521 and the second sub-plate 523, that is, the connecting plate 522 is bent and connected between the first sub-plate 521 and the second sub-plate 523.

[0065] In some embodiments, such as Figure 3 and Figures 5-6 As shown, the first sub-plate 521, the connecting plate 522, and the second sub-plate 523 together define the installation area 53. The first sub-plate 521, the connecting plate 522, and the second sub-plate 523 are provided with a first limiting flange 524 on the side near the installation area 53 to prevent other components inside the air conditioner from contacting the edge of the valve island bracket 52 and to prevent scratching other components.

[0066] In some embodiments, such as Figure 3 and Figures 5-6 As shown, the first sub-plate 521, the connecting plate 522, and the second sub-plate 523 together define the installation area 53. The first sub-plate 521, the connecting plate 522, and the second sub-plate 523 are provided with a first limiting flange 524 on the side near the installation area 53 to prevent other components inside the air conditioner from contacting the edge of the valve island bracket 52 and to prevent scratching other components.

[0067] In some embodiments of this utility model, the first sub-plate 521 and the second sub-plate 523 both extend horizontally, and the connecting plate 522 extends vertically, and as shown... Figure 3 The first sub-plate 521 and the second sub-plate 523 are located on the same side of the connecting plate 522 in the horizontal direction. The valve island bracket 52 occupies less space in the horizontal direction, and the valve island assembly 5 is smaller in size, reducing the installation space requirement of the valve island assembly 5 inside the air conditioner.

[0068] In some embodiments, such as Figure 3 and Figure 5 As shown, the support member 3 also includes at least one first positioning part 31, and the valve island bracket 52 is provided with a positioning groove 525, in which the first positioning part 31 passes through the positioning groove 525.

[0069] Specifically, the support member 3 may be provided with at least one first positioning part 31, that is, the support member 3 may be provided with one, two, or three first positioning parts 31. The first positioning part 31 may be a positioning post, etc., and the first positioning part 31 may also be an inlet post or an outlet post of the support member 3, thereby improving the integration of the structure, reducing the need for other structural components, and lowering the installation cost. In actual installation, the valve island bracket 52 can be installed on the support member 3 first, such as... Figure 3 As shown, the valve island bracket 52 is provided with a positioning groove 525, which allows the positioning groove 525 of the valve island bracket 52 to be positioned and engaged with the first positioning part 31. After the valve island bracket 52 is installed, the valve island body 51 is then installed on the valve island bracket 52 to ensure installation accuracy.

[0070] In some embodiments, such as Figure 3 and Figure 5As shown, the first positioning part 31 passes through the positioning groove 525 and is positioned and engaged with the valve island body 51. By positioning and engaging both the valve island bracket 52 and the valve island body 51 with the first positioning part 31, a first positioning engagement part can be provided on the valve island body 51, and the first positioning part 31 can be positioned and engaged with both the positioning groove 525 and the first positioning engagement part, so that the valve island bracket 52 and the valve island body 51 can be installed together on the support member 3, and the installation method is flexible.

[0071] In this embodiment, the end face of the first positioning part 31 facing away from the support member 3 abuts against the valve island body 51, thereby achieving the positioning and cooperation between the first positioning part 31 and the valve island body 51.

[0072] In some embodiments, the support member 3 can be an oil-gas separator or a gas-liquid separator. The first positioning part 31 is provided on the upper end of the support member 3. The first positioning part 31 is connected to the valve island body 51 through multiple refrigerant pipeline components 4 to form a refrigerant circuit, so that the oil-gas separator or gas-liquid separator is connected to the compressor 2 through the refrigerant pipeline components 4 to realize the flow of refrigerant.

[0073] In some embodiments, such as Figure 7 As shown, the valve island assembly 5 also includes a connecting structure 8, which is used to connect the support 3 to the valve island bracket 52.

[0074] The connecting structure 8 can be set as bolts, etc., which is simple in structure and low in installation cost. The connecting structure 8 is used to connect the support member 3 to the valve island bracket 52. In actual installation, the valve island bracket 52 can be connected to the support member 3 first through the connecting structure 8, such as... Figure 3 As shown, the valve island bracket 52 is provided with a connection hole 526, and the connection structure 8 can be inserted into the connection hole 526 to connect the valve island bracket 52 with the support member 3.

[0075] In some embodiments, the connecting structure 8 is sequentially connected to the valve island bracket 52 and the valve island body 51. The connecting structure 8 sequentially connects the valve island bracket 52 and the valve island body 51 to the support member 3, providing a flexible installation method and making both the valve island bracket 52 and the valve island body 51 detachable from the support member 3, thereby improving the convenience of later maintenance and saving maintenance time.

[0076] In addition, the valve island bracket 52 can be connected to the support member 3 by welding or other means, and the valve island body 51 is connected to the valve island bracket 52 through the connecting structure 8, so that the valve island body 51 is detachable relative to the valve island bracket 52, which can also improve the convenience of later maintenance and save maintenance time.

[0077] In actual installation, the valve island bracket 52 can be installed on the support 3 first, and the refrigerant piping component 4 and the valve island body 51 can be pre-installed. Then, the pre-installed refrigerant piping component 4 and the valve island body 51 can be installed together on the valve island bracket 52, which can improve installation efficiency, save installation time, and reduce production costs. Leak detection can be performed after pre-installation, which can save final assembly welding time, reduce the number of weld points during final assembly, reduce the probability of leakage during final assembly, and improve installation reliability.

[0078] In some embodiments, there are multiple first positioning parts 31 and two connecting structures 8, which are symmetrically distributed on both sides of the first positioning part 31.

[0079] Specifically, the support member 3 may be provided with a first positioning part 31, and there may be multiple first positioning parts 31. The valve island bracket 52 can be positioned and cooperated with the first positioning part 31 through the positioning groove 525 to ensure installation accuracy. The connecting structure 8 is provided as two, and the two connecting structures 8 can be symmetrically distributed on both sides of the first positioning part 31. When the valve island bracket 52 is installed on the support member 3, the two connecting structures 8 are subjected to the same force, which can avoid problems such as deformation and connection failure caused by excessive force on one of the connecting structures 8, so as to ensure connection reliability.

[0080] In some embodiments, the valve island bracket 52 and the support member 3 are connected by welding, or the valve island bracket 52 and the support member 3 are detachably connected. The valve island bracket 52 can be installed on the support member 3 by welding, which is convenient for installation. Alternatively, the valve island bracket 52 can be detachably installed on the support member 3 by means of connectors, such as bolts or rivets, which has low installation cost and facilitates later maintenance, saving maintenance time. Furthermore, the valve island bracket 52 and the support member 3 can be made of the same material or different materials, which is flexible in terms of installation method.

[0081] In other embodiments, the support member 3 is provided with at least one second positioning part, which is spaced apart from the first positioning part 31. The second positioning part is positioned and engaged with the valve island bracket 52, or the second positioning part is positioned and engaged with the valve island bracket 52 and the valve island body 51 in sequence.

[0082] Specifically, the support member 3 is also provided with a second positioning part. The second positioning part can be at least one, that is, one, two or three, etc. The second positioning part can be a positioning protrusion or a positioning groove, etc. The valve island bracket 52 is also provided with a second positioning mating part. The second positioning mating part can also be a positioning protrusion or a positioning groove, etc. The second positioning part and the second positioning mating part are provided in a one-to-one correspondence, so that when the valve island bracket 52 is installed on the support member 3, the second positioning part can be positioned and mated with the second positioning mating part to improve the installation accuracy.

[0083] In addition, a second positioning and mating part can be provided on the valve island body 51, so that the second positioning part can be positioned and mated with the valve island bracket 52 and the valve island body 51 in sequence, so as to ensure the accuracy when the valve island bracket 52 and the valve island body 51 are installed together on the support member 3. The second positioning part is spaced apart from the first positioning part 31, so that if one of the two positioning parts is damaged, the other can still be positioned, ensuring the reliability of positioning.

[0084] In some embodiments, the valve island body 51 and the valve island support 52 are connected by welding, or the valve island body 51 and the valve island support 52 are detachably connected. The valve island body 51 can be installed on the valve island support 52 by welding, which is convenient for installation. Alternatively, the valve island body 51 can be detachably installed on the valve island support 52 by means of connectors, such as bolts or rivets, which has low installation cost and facilitates later maintenance, saving maintenance time. Furthermore, the valve island body 51 and the valve island support 52 can be made of the same or different materials, which is flexible in terms of installation method.

[0085] In some embodiments, the compressor 2 and the support member 3 are arranged side by side in the compressor cavity and are both mounted and supported on the bottom wall of the housing 1.

[0086] Specifically, the compressor cavity is equipped with a compressor 2 and a support component 3, which are spaced apart and arranged side by side within the compressor cavity. This avoids interference between the compressor 2 and the support component 3, ensuring the reliability of their use. Both the compressor 2 and the support component 3 are mounted and supported on the bottom wall of the casing 1. The compressor 2 can be detachably mounted on the bottom wall of the casing 1 via connectors, etc., facilitating maintenance and replacement of the compressor 2. Similarly, the support component 3 can also be detachably mounted on the bottom wall of the casing 1 via connectors, etc., facilitating maintenance and replacement of the support component 3, thereby saving time and costs associated with later maintenance of the air conditioner.

[0087] In some embodiments, such as Figure 1 and Figure 2 As shown, the compressor 2 and the support 3 are both located below the valve island assembly 5. The top of the support 3 is connected to the valve island assembly 5, and the top of the compressor 2 is spaced apart from the valve island assembly 5 to jointly define the partition space 7.

[0088] Specifically, the valve island assembly 5 is installed on top of the support member 3, and the length of the compressor 2 is set to be less than the length of the support member 3, so that the compressor 2 and the support member 3 can both be set below the valve island assembly 5, and the top of the compressor 2 is spaced apart from the valve island assembly 5, that is, there is a height difference between the top of the compressor 2 and the top of the support member 3, which in turn defines the partition space 7, so that the valve island assembly 5 can be located in the partition space 7, and the vertical projection of the valve island assembly 5 overlaps at least partially with the vertical projection of the compressor 2, which can improve the utilization rate of the space inside the compressor cavity, thereby reducing the space occupied by the air conditioner and improving the lightweight of the air conditioner.

[0089] In some embodiments, the air conditioner further includes a tank mounting bracket 6, wherein the support member 3 is detachably connected to the bottom wall of the housing 1 via the tank mounting bracket 6.

[0090] Specifically, such as Figures 1-2 and Figures 4-6 As shown, the air conditioner is also equipped with a tank mounting bracket 6, which is installed at the bottom of the support member 3. The support member 3 can be detachably connected to the bottom wall of the housing 1 through the tank mounting bracket 6. That is, the support member 3 can be connected to the tank mounting bracket 6 through connectors, and the tank mounting bracket 6 can also be connected to the bottom wall of the housing 1 through connectors. This makes the support member 3 detachable from the bottom wall of the housing 1, which facilitates the later maintenance of the support member 3. Furthermore, the connection between the support member 3 and the bottom wall of the housing 1 through the tank mounting bracket 6 reduces the contact area between the support member 3 and the housing 1, thereby reducing the transmission of vibration through the support member 3 to the housing 1, reducing the noise generated during the operation of the air conditioner, and improving the user experience.

[0091] In some embodiments, such as Figure 4 As shown, the tank 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 support member 3 is supported on the mounting top plate 61, and the mounting bottom plate 63 is supported on the bottom wall of the casing 1.

[0092] Specifically, the support member 3 can be detachably connected to the bottom wall of the casing 1 via the tank mounting bracket 6, and as... Figure 4 As shown, the tank mounting bracket 6 is provided with 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 both arranged in the horizontal direction and are spaced apart in the vertical direction. The intermediate plate 62 extends in the vertical direction and its upper and lower ends are connected to the mounting top plate 61 and the mounting bottom plate 63 respectively. The bottom of the support member 3 is detachably connected to and supported by the mounting top plate 61, and the mounting bottom plate 63 is detachably connected to and supported by the bottom wall of the casing 1.

[0093] 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 support 3 can be increased, as can the contact area between the mounting bottom plate 63 and the bottom wall of the casing 1, ensuring the reliability of the support. Furthermore, by extending the intermediate plate 62 vertically, the connection area between the intermediate plate 62 and the mounting top plate 61 and the mounting bottom plate 63 can be reduced, thereby reducing the transmission of vibration, reducing the noise generated during the operation of the air conditioner, and improving the user's comfort.

[0094] In addition, a tank mounting bracket 6 is provided at the bottom of the support member 3, so that there is a height difference between the top of the support member 3 and the top of the compressor 2. This allows the valve island assembly 5 to be staggered from the top of the compressor 2, avoiding interference between the structures and ensuring the operational reliability of each structure. Both the mounting top plate 61 and the mounting bottom plate 63 are provided with a second limiting flange 64. The second limiting flange 64 of the mounting top plate 61 can limit the support member 3 to ensure installation reliability, and the second limiting flange 64 of the mounting bottom plate 63 can improve the structural strength of the mounting bottom plate 63 to ensure the reliability of supporting the support member 3.

[0095] In some embodiments, such as Figure 8 As shown, the refrigerant piping component 4 also includes an oil-gas separator 42, a four-way valve 43, an electronic expansion valve 44, a solenoid valve 45, a high-pressure valve 46, and a low-pressure valve 47. The oil-gas separator 42, the four-way valve 43, the electronic expansion valve 44, the solenoid valve 45, the high-pressure valve 46, and the low-pressure valve 47 are all connected to the valve island assembly 5.

[0096] Specifically, the refrigerant piping component 4 is located inside the compressor cavity and is connected to the valve island assembly 5, such as... Figure 5 As shown, the refrigerant piping component 4 also includes an oil-gas separator 42, a four-way valve 43, an electronic expansion valve 44, a solenoid valve 45, a high-pressure valve 46, and a low-pressure valve 47. The oil-gas separator 42 can separate the refrigerant oil discharged from the compressor 2 and return it to the compressor 2 through the return oil pipeline to ensure the reliability of the compressor 2. The oil-gas separator 42 can be connected to the compressor 2 and the four-way valve 43 respectively.

[0097] Furthermore, the four-way valve 43 can be used to switch between cooling and heating modes and change the refrigerant flow direction. In cooling mode, the four-way valve 43 can be connected to the plate heat exchanger 41. At this time, the plate heat exchanger 41 can act as a condenser, where high-temperature and high-pressure gas releases heat and condenses into a high-pressure liquid. In heating mode, the four-way valve 43 can be connected to the indoor unit of the air conditioner. At this time, the plate heat exchanger 41 acts as an evaporator, where low-temperature and low-pressure liquid absorbs heat and vaporizes. The plate heat exchanger 41 is also connected to the electronic expansion valve 44, which can throttle and reduce pressure, regulate the refrigerant flow, and ensure the reliable operation of the air conditioning equipment.

[0098] Furthermore, the high-pressure valve 46 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 41 or the electronic expansion valve 44. The low-pressure valve 47 connects to the low-pressure pipeline between the outdoor unit and the indoor unit of the air conditioner, and is usually connected to the four-way valve 43 or the support component 3. The support component 3 can store excess refrigerant to prevent liquid refrigerant from entering the compressor 2 and ensure the reliable operation of the compressor 2. In addition, the solenoid valve 45 can be set as a single-way solenoid valve 45. The single-way solenoid valve 45 can control the flow of refrigerant, such as cutting off part of the circuit during defrosting. The single-way solenoid valve 45 can be connected in series in the high-pressure pipeline or the bypass pipeline to increase the application scenarios of the air conditioning equipment.

[0099] In some embodiments, a compressor chamber and a fan chamber are formed separately within the housing 1, a fan assembly is installed in the fan chamber, and a compressor 2 is installed in the compressor chamber.

[0100] Specifically, a partition can be installed inside the air conditioner. The partition can be connected to the casing 1 by means of connectors or welding. The connectors can be bolts, etc. The structure is simple, easy to install, and has low installation cost. An installation space is formed inside the casing 1, and the partition can divide the installation space into a fan cavity and a compressor cavity. A fan assembly can be installed in the fan cavity. The fan assembly is equipped with a drive motor, fan blades, and a heat exchanger. The drive motor can drive the fan blades to rotate, and when the fan blades rotate, they can dissipate heat and cool the heat exchanger to ensure the stability of the heat exchanger operation. The compressor 2 can be installed in the compressor cavity.

[0101] In this way, the fan cavity and the compressor cavity can be separated by a partition, so that when the drive motor, fan blades and compressor 2 are running, the partition can block the vibration between the fan cavity and the compressor cavity, so as to avoid interference between the structure inside the fan cavity and the structure inside the compressor cavity, and ensure the reliability of the air conditioner operation.

[0102] In some embodiments, the support member 3 is a gas-liquid separator, a liquid storage tank, a flash tank, or a phase separation tank. Different support members 3 can be selected and installed according to the operating requirements of the air conditioner to meet different design needs.

[0103] In some embodiments, at least a portion of the valve island assembly 5 is made of stainless steel, for example, at least a portion of the valve island support 52 is made of stainless steel, or at least a portion of the valve island body 51 is made of stainless steel, or at least a portion of both the valve island body 51 and the valve island support 52 are made of stainless steel.

[0104] At least a portion of the valve island support 52 is made of stainless steel, which ensures the structural strength of the valve island support 52 and improves the installation reliability of the valve island body 51. At least a portion of the valve island body 51 is made of stainless steel, which, while ensuring the structural strength of the valve island body 51, also increases the corrosion resistance of the valve island body 51, preventing the refrigerant from corroding the valve island body 51 when it flows through it.
