[0041] The following is for reference. Figures 1-8 The air conditioner described according to the present invention can block the sound radiation path generated by vibration, 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.

[0042] like Figures 1-8 As shown, an air conditioner according to one embodiment of the present invention includes: a housing 1, a compressor assembly, and a valve island assembly 5.

[0043] The compressor assembly is installed inside the housing 1. The compressor assembly includes a compressor 2, a gas-liquid separator 3, and multiple refrigerant piping components 4. The gas-liquid separator 3 is connected to the housing 1. The valve island assembly 5 is installed and supported on the gas-liquid separator 3. The multiple refrigerant piping components 4 are connected to the valve island assembly 5 and communicate with the compressor 2 and the gas-liquid separator 3 to form a refrigerant circuit.

[0044] 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.

[0045] 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.

[0046] The casing 1 can be equipped with a compressor assembly, which includes a compressor 2, a gas-liquid separator 3, and multiple refrigerant piping components 4. The multiple refrigerant piping components 4 can be equipped with a four-way valve 43, an electronic expansion valve 44, a plate heat exchanger 41, a gas-liquid separator 3, an oil separator, 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 and the gas-liquid separator 3 to form a refrigerant circuit to ensure the reliability of the air conditioner operation.

[0047] Furthermore, the air conditioner is also equipped with a valve island assembly 5. The valve island assembly 5 can be installed and supported on the gas-liquid separator 3 by means of connectors or welding. The gas-liquid separator 3 can be connected to the casing 1 by means of connectors or welding. The compressor 2 is distributed separately from the gas-liquid separator 3 and can also be connected to the casing 1 by means of connectors or welding. Thus, the valve island assembly 5 can be fixedly installed in the casing 1 only through the gas-liquid separator 3. Multiple refrigerant pipeline components 4 can be connected to the valve island assembly 5, and multiple refrigerant pipeline components 4 can be connected to the compressor 2 and the gas-liquid separator 3 to form a refrigerant circuit. This allows the valve island assembly 5 to be distributed separately 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 the operation of the air conditioner and improving the user experience.

[0048] In addition, multiple refrigerant piping components 4 are connected to the valve island assembly 5, which shortens the length of the refrigerant piping and reduces the space occupied by multiple refrigerant piping, thereby improving integration and weight reduction, and reducing installation costs. At the same time, it can reduce the number of connection points of multiple refrigerant piping, thereby reducing the risk of leakage of refrigerant and other media and improving the reliability of air conditioning.

[0049] According to the embodiment of the present invention, the air conditioner connects multiple refrigerant pipeline components 4 to the compressor 2 and the gas-liquid separator 3 through the valve island assembly 5 to form a refrigerant circuit. In this way, the sound radiation path generated by the vibration of the compressor 2 can be blocked by 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.

[0050] In some embodiments, the valve island assembly 5 includes a valve island body 51 and a valve island support 52. The valve island support 52 is mounted and supported on the gas-liquid separator 3, the valve island body 51 is supported above the valve island support 52, and a plurality of refrigerant piping components 4 are connected to the valve island body 51.

[0051] Specifically, such as Figures 1-2 and Figure 8 As shown, the valve island assembly 5 is mounted and supported on the gas-liquid separator 3. The valve island assembly 5 is provided with a valve island body 51 and a valve island bracket 52. The valve island bracket 52 can be installed on the gas-liquid separator 3 by welding or connecting parts, and the valve island body 51 can be installed and supported on the top of the valve island bracket 52. This allows the valve island body 51 to be mounted and supported on the gas-liquid separator 3 through the valve island bracket 52, which is convenient for installation. It also ensures that the valve island body 51 is only connected to the gas-liquid separator 3, thereby isolating the vibration generated by the operation of other structures, reducing the noise generated during the operation of the air conditioner, and improving the user experience.

[0052] Furthermore, multiple refrigerant piping components 4 are connected to the valve island body 51, which can shorten the length of the refrigerant piping, improve integration, reduce the space occupied by multiple refrigerant piping, improve lightweighting, and reduce production costs. In actual installation, the valve island bracket 52 can be made of carbon steel, stainless steel, aluminum alloy, etc., which can ensure the structural strength of the valve island bracket 52 and improve the installation reliability of the valve island body 51.

[0053] 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.

[0054] In some embodiments, at least a portion of the valve island support 52 is spaced apart from the valve island body 51 and together defines an installation area 53. A plurality of refrigerant piping components 4 include a plate heat exchanger 41, which is connected to the valve island body 51 and located within the installation area 53.

[0055] 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.

[0056] Furthermore, the valve island body 51 is mounted on the gas-liquid separator 3 via the valve island support 52, and at least a portion of the valve island support 52 is spaced apart from the valve island body 51, that is, the valve island body 51 is only partially connected to the valve island support 52 to connect to the gas-liquid separator 3, and another portion of the valve island body 51 can be spaced apart from the valve island support 52, so that the other portion of the valve island body 51 and the valve island support 52 can jointly define the installation area 53, and the plate heat exchanger 41 can be disposed within the installation area 53.

[0057] Thus, the valve island bracket 52 can support both the valve island body 51 and the plate heat exchanger 41, ensuring the reliability of their installation. It also allows the valve island body 51 and the plate heat exchanger 41 to be connected to the gas-liquid separator 3 only through the valve island bracket 52, thus isolating vibration, ensuring the reliability of air conditioning operation, and improving the user experience. Furthermore, directly connecting the plate heat exchanger 41 to the valve island body 51 reduces the need for refrigerant piping, lowering installation costs, and increasing integration for weight reduction.

[0058] In some embodiments, the valve island support 52 includes a first sub-plate 521, a connecting plate 522 and a second sub-plate 523. The connecting plate 522 is bent and connected between the first sub-plate 521 and the second sub-plate 523. The first sub-plate 521 is connected to the gas-liquid separator 3. The connecting plate 522 and the second sub-plate 523 together with the valve island body 51 define the installation area 53.

[0059] Specifically, the valve island body 51 can be connected to the gas-liquid separator 3 via the valve island support 52, and as shown in the figure. Figures 2-3As shown, the valve island support 52 is provided with a first sub-plate 521, a connecting plate 522, and a second sub-plate 523. The first sub-plate 521 and the second sub-plate 523 are spaced apart, and one end of the connecting plate 522 is bent and connected to the first sub-plate 521, while the other end of the connecting plate 522 is bent and connected to the second sub-plate 523. That is, the connecting plate 522 is bent and connected between the first sub-plate 521 and the second sub-plate 523. The connecting plate 522 is connected to the side of the first sub-plate 521 and the second sub-plate 523 that is close to each other. The end of the first sub-plate 521 away from the connecting plate 522 can extend to connect with the gas-liquid separator 3, and the end of the second sub-plate 523 away from the connecting plate 522 can extend in a direction away from the gas-liquid separator 3, so that the connecting plate 522, the second sub-plate 523, and the valve island body 51 can jointly define the installation area 53.

[0060] Thus, the gas-liquid separator 3 can support the valve island bracket 52 to improve the installation reliability of the valve island body 51. The connecting plate 522, the second sub-plate 523 and the valve island body 51 define an installation area 53, within which the plate heat exchanger 41 can be installed. The second sub-plate 523 can support the plate heat exchanger 41, thereby improving the installation reliability of the plate heat exchanger 41, increasing space utilization, improving integration and weight reduction, and reducing the installation cost by minimizing the refrigerant piping.

[0061] In some embodiments, the connecting plate 522 extends vertically, and the first sub-plate 521 and the second sub-plate 523 both extend horizontally and are connected to the upper and lower ends of the connecting plate 522. The first sub-plate 521 and the second sub-plate 523 are located on different sides of the connecting plate 522, wherein the first sub-plate 521 is supported on the top surface of the gas-liquid separator 3, and the plate heat exchanger 41 is supported above the second sub-plate 523.

[0062] Specifically, the connecting plate 522 is bent and connected between the first sub-plate 521 and the second sub-plate 523, and as shown in the figure. Figure 3 and Figures 5-6 As shown, the first sub-plate 521 is configured to extend horizontally, the second sub-plate 523 is also configured to extend horizontally, and the connecting plate 522 is configured to extend vertically, so that the first sub-plate 521 and the second sub-plate 523 can be vertically connected to the upper and lower ends of the connecting plate 522 respectively. The first sub-plate 521 is connected to the top surface of the gas-liquid separator 3, and the top surface of the gas-liquid separator 3 is also configured to extend horizontally, so that the first sub-plate 521 can be closely connected to the top surface of the gas-liquid separator 3, thereby improving the support reliability of the gas-liquid separator 3 on the first sub-plate 521, so as to ensure the installation reliability of the valve island body 51.

[0063] Furthermore, the gas-liquid separator 3 can be configured as a columnar structure, that is, the side wall of the gas-liquid separator 3 can be set perpendicular to the top surface, so that when the first sub-plate 521 is connected to the top surface of the gas-liquid separator 3, the side wall of the gas-liquid separator 3 can support the connecting plate 522, thereby dispersing the force on the valve island support 52 and improving the reliability of the valve island support 52.

[0064] In addition, the second sub-plate 523 also extends horizontally, and the first sub-plate 521 and the second sub-plate 523 are located on different sides of the connecting plate 522, that is, the second sub-plate 523 extends away from the gas-liquid separator 3, so that the second sub-plate 523, the connecting plate 522 and the valve island body 51 can define an installation area 53, and the bottom of the plate heat exchanger 41 can contact the second sub-plate 523 to ensure the reliability of the support for the plate heat exchanger 41, and reduce the force on the bottom of the valve island body 51, thus ensuring the installation reliability of the valve island body 51.

[0065] In some embodiments, the second subplate 523 has a first limiting flange 524 on the side edge away from the connecting plate 522. The first limiting flange 524 is bent upward and distributed opposite to the connecting plate 522. The first limiting flange 524 is used to limit the engagement with the plate heat exchanger 41.

[0066] Specifically, one side of the second sub-plate 523 is connected to the connecting plate 522, and the other side extends away from the connecting plate 522, and as shown... Figure 3 The second sub-plate 523 has a first limiting flange 524 formed on the side away from the connecting plate 522. The first limiting flange 524 extends upward on the side of the second sub-plate 523 away from the connecting plate 522. The first limiting flange 524 and the connecting plate 522 are relatively distributed, so that a limiting space can be defined between the first limiting flange 524 and the connecting plate 522. The limiting space is connected to the installation area 53. The plate heat exchanger 41 can extend from the installation area 53 into the limiting space, so that the first limiting flange 524 and the connecting plate 522 can limit the plate heat exchanger 41, thereby improving the installation accuracy. It can also limit the plate heat exchanger 41 in the horizontal direction, thereby improving the reliability of the connection between the plate heat exchanger 41 and the valve island body 51.

[0067] In some embodiments, the gas-liquid separator 3 is provided with at least one first positioning part 31, which is positioned and cooperates with the valve island support 52, or the first positioning part 31 is positioned and cooperates with the valve island support 52 and the valve island body 51 in sequence.

[0068] Specifically, the gas-liquid separator 3 may be provided with at least one first positioning part 31, that is, the gas-liquid separator 3 may be provided with one, two or three first positioning parts 31, the first positioning part 31 may be a positioning column, etc., and the first positioning part 31 may also be the inlet column or outlet column of the gas-liquid separator 3, etc., thereby improving the integration of the structure, reducing the setting of other structures, and reducing the setting cost.

[0069] Furthermore, the first positioning part 31 can be configured to position and cooperate with the valve island bracket 52, or the first positioning part 31 can also be configured to position and cooperate with the valve island bracket 52 and the valve island body 51 in sequence. That is, in actual installation, the valve island bracket 52 can be installed on the gas-liquid separator 3 first, such as... Figure 2 and Figure 5 As shown, the valve island bracket 52 is provided with a first positioning mating part 525. The first positioning mating part 525 can be configured as a positioning hole, etc., so that the first positioning mating part 525 of the valve island bracket 52 can be positioned and mated with the first positioning part 31. After the valve island bracket 52 is installed, the valve island body 51 is then installed on the valve island bracket 52 to ensure installation accuracy.

[0070] In addition, the valve island bracket 52 and the valve island body 51 can be positioned and engaged with the first positioning part 31. That is, the first positioning part 525 can be provided on both the valve island bracket 52 and the valve island body 51, and the first positioning part 31 can be positioned and engaged with the two first positioning parts 525 respectively, so that the valve island bracket 52 and the valve island body 51 can be installed together on the gas-liquid separator 3, and the installation method is flexible.

[0071] In some other embodiments, the air conditioner also includes a connection structure 8 for connecting the gas-liquid separator 3 to the valve island support 52, or the connection structure 8 is connected in sequence to the valve island support 52 and the valve island body 51.

[0072] Specifically, the air conditioner also includes a connecting structure 8, which can be made of bolts, etc. The structure is simple and has low installation cost. The connecting structure 8 is used to connect the gas-liquid separator 3 to the valve island bracket 52, or to connect the connecting structure 8 sequentially to the valve island bracket 52 and the valve island body 51. That is, during actual installation, the valve island bracket 52 can be connected to the gas-liquid separator 3 first through the connecting structure 8. Figure 3 As shown, the valve island bracket 52 is provided with a connection hole 527. The connection structure 8 can be inserted into the connection hole 527 to connect the valve island bracket 52 to the gas-liquid separator 3. Then, the valve island body 51 is connected to the valve island bracket 52. Alternatively, the valve island bracket 52 and the valve island body 51 can be connected to the gas-liquid separator 3 in sequence through the connection structure 8. The installation method is flexible, and both the valve island bracket 52 and the valve island body 51 are detachable from the gas-liquid separator 3 to improve the convenience of later maintenance and save maintenance time.

[0073] In addition, the valve island support 52 can be connected to the gas-liquid separator 3 by welding or other means, and the valve island body 51 is connected to the valve island support 52 through the connecting structure 8, so that the valve island body 51 is detachable relative to the valve island support 52, which can also improve the convenience of later maintenance and save maintenance time.

[0074] In actual installation, the valve island bracket 52 can be installed on the gas-liquid separator 3 first, and the refrigerant piping components 4 and the valve island body 51 can be pre-installed. Then, the pre-installed refrigerant piping components 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.

[0075] In some embodiments, the first positioning part 31 is one, and the connecting structure 8 is two, with the two connecting structures 8 symmetrically distributed on both sides of the first positioning part 31.

[0076] Specifically, the gas-liquid separator 3 may be provided with a first positioning part 31, and the first positioning part 31 may be set as one. The valve island bracket 52 may be positioned and engaged with the first positioning part 31 through the first positioning mating part 525 to ensure installation accuracy. The connecting structure 8 may be set as two, and the two connecting structures 8 may be symmetrically distributed on both sides of the first positioning part 31. This ensures that when the valve island bracket 52 is installed in the gas-liquid separator 3, the two connecting structures 8 are subjected to the same force, which can avoid problems such as deformation or connection failure caused by excessive force on one of the connecting structures 8, so as to ensure connection reliability.

[0077] In other embodiments, the gas-liquid separator 3 is provided with at least one second positioning part, which is spaced apart from the first positioning part 31. The second positioning part is positioned and engaged with the valve island support 52, or the second positioning part is positioned and engaged with the valve island support 52 and the valve island body 51 in sequence.

[0078] Specifically, the gas-liquid separator 3 is also provided with a second positioning part. The second positioning part can be at least one, that is, one, two or three, etc. The second positioning part can be a positioning protrusion or a positioning groove, etc. The valve island bracket 52 is also provided with a second positioning mating part 526. The second positioning mating part 526 can also be a positioning protrusion or a positioning groove, etc. The second positioning part and the second positioning mating part 526 are provided in a one-to-one correspondence, so that when the valve island bracket 52 is installed on the gas-liquid separator 3, the second positioning part can be positioned and mated with the second positioning mating part 526 to improve the installation accuracy.

[0079] In addition, a second positioning and mating part 526 can be provided on the valve island body 51, so that the second positioning part can be positioned and mated with the valve island bracket 52 and the valve island body 51 in sequence, so as to ensure the accuracy when the valve island bracket 52 and the valve island body 51 are installed together in the gas-liquid separator 3. The second positioning part is spaced apart from the first positioning part 31, so that if one of the two positioning parts is damaged, the other can still be positioned, thus ensuring the reliability of positioning.

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

[0081] In other embodiments, the valve island body 51 and the valve island support 52 are connected by welding, or the valve island body 51 and the valve island support 52 are detachably connected. The valve island body 51 can be installed on the valve island support 52 by welding, which is convenient for installation. Alternatively, the valve island body 51 can be detachably installed on the valve island support 52 by means of connectors, such as bolts or rivets, which has low installation cost and facilitates later maintenance, saving maintenance time. Furthermore, the valve island body 51 and the valve island support 52 can be made of the same or different materials, which is flexible in terms of installation method.

[0082] In some embodiments, the compressor 2 and the gas-liquid separator 3 are arranged side by side in the compressor cavity and are both mounted and supported on the bottom wall of the housing 1.

[0083] Specifically, the compressor cavity is equipped with a compressor 2 and a gas-liquid separator 3, which are spaced apart and arranged side by side within the compressor cavity. This avoids interference between the compressor 2 and the gas-liquid separator 3, ensuring the reliability of their operation. Both the compressor 2 and the gas-liquid separator 3 are mounted and supported on the bottom wall of the casing 1. The compressor 2 can be detachably mounted on the bottom wall of the casing 1 via connectors, facilitating maintenance and replacement of the compressor 2. Similarly, the gas-liquid separator 3 can also be detachably mounted on the bottom wall of the casing 1 via connectors, facilitating maintenance and replacement of the gas-liquid separator 3. This saves on air conditioner maintenance time and costs in the later stages.

[0084] In some embodiments, the compressor 2 and the gas-liquid separator 3 are both located below the valve island assembly 5, the top of the gas-liquid separator 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.

[0085] Specifically, the valve island assembly 5 is installed on top of the gas-liquid separator 3, and the length of the compressor 2 is set to be less than the length of the gas-liquid separator 3, so that the compressor 2 and the gas-liquid separator 3 can both be set below the valve island assembly 5, and the top of the compressor 2 is spaced apart from the valve island assembly 5, that is, there is a height difference between the top of the compressor 2 and the top of the gas-liquid separator 3, which in turn defines the partition space 7, so that the valve island assembly 5 can be located in the partition space 7, and the vertical projection of the valve island assembly 5 overlaps at least partially with the vertical projection of the compressor 2, which can improve the utilization rate of the space inside the compressor cavity, thereby reducing the space occupied by the air conditioner and improving the lightweight of the air conditioner.

[0086] In some embodiments, the air conditioner further includes: a gas separator mounting bracket 6, wherein the gas-liquid separator 3 is detachably connected to the bottom wall of the housing 1 via the gas separator mounting bracket 6.

[0087] Specifically, such as Figures 1-2 and Figures 4-6 As shown, the air conditioner is also equipped with a gas separator mounting bracket 6, which is installed at the bottom of the gas-liquid separator 3. The gas-liquid separator 3 can be detachably connected to the bottom wall of the casing 1 through the gas separator mounting bracket 6. That is, the gas-liquid separator 3 can be connected to the gas separator mounting bracket 6 through connectors, and the gas separator mounting bracket 6 can also be connected to the bottom wall of the casing 1 through connectors. This makes the gas-liquid separator 3 detachable from the bottom wall of the casing 1, which facilitates the later maintenance of the gas-liquid separator 3. Furthermore, the connection between the gas-liquid separator 3 and the bottom wall of the casing 1 through the gas separator mounting bracket 6 reduces the contact area between the gas-liquid separator 3 and the casing 1, thereby reducing the vibration transmitted from the gas-liquid separator 3 to the casing 1, reducing the noise generated during the operation of the air conditioner, and improving the user experience.

[0088] In some embodiments, the gas separator mounting bracket 6 includes a top mounting plate 61, a middle plate 62, and a bottom mounting plate 63. The top mounting plate 61 and the bottom mounting plate 63 are spaced apart and opposite to each other and connected to the two ends of the middle plate 62. The bottom of the gas-liquid separator 3 is supported on the top mounting plate 61, and the bottom mounting plate 63 is supported on the bottom wall of the housing 1.

[0089] Specifically, the gas-liquid separator 3 can be detachably connected to the bottom wall of the housing 1 via the gas separation mounting bracket 6, and as... Figure 4 As shown, the gas separator mounting bracket 6 is provided with a mounting top plate 61, a middle 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 middle 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 gas-liquid separator 3 is detachably connected and supported by the mounting top plate 61, and the mounting bottom plate 63 is detachably connected and supported by the bottom wall of the housing 1.

[0090] 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 gas-liquid separator 3 can be increased, as can the contact area between the mounting bottom plate 63 and the bottom wall of the casing 1, ensuring reliable support. Furthermore, by extending the intermediate plate 62 vertically, the connection area between the intermediate plate 62 and the mounting top plate 61 and the mounting bottom plate 63 can be reduced, thereby reducing the transmission of vibration, reducing the noise generated during air conditioner operation, and improving user comfort.

[0091] In addition, a gas-liquid separator mounting bracket 6 is provided at the bottom of the gas-liquid separator 3, so that there is a height difference between the top of the gas-liquid separator 3 and the top of the compressor 2. This allows the valve island assembly 5 to be staggered from the top of the compressor 2, avoiding interference between the structures and ensuring the operational reliability of each structure. Both the mounting top plate 61 and the mounting bottom plate 63 are provided with a second limiting flange 64. The second limiting flange 64 of the mounting top plate 61 can limit the gas-liquid separator 3 to ensure installation reliability, and the second limiting flange 64 of the mounting bottom plate 63 can improve the structural strength of the mounting bottom plate 63 to ensure the reliability of the support for the gas-liquid separator 3.

[0092] In some embodiments, the refrigerant piping component 4 further 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, all of which are connected to the valve island assembly 5.

[0093] Specifically, the refrigerant piping component 4 is located inside the compressor cavity and is connected to the valve island assembly 5, 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 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.

[0094] 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.

[0095] 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 gas-liquid separator 3. The gas-liquid separator 3 can store excess refrigerant to prevent liquid refrigerant from entering the compressor 2, ensuring the reliable operation of the compressor 2. In addition, the solenoid valve 45 can be set as a single-way solenoid valve. The single-way solenoid valve can control the flow of refrigerant, such as cutting off part of the circuit during defrosting. The single-way solenoid valve can be connected in series in the high-pressure pipeline or the bypass pipeline to increase the application scenarios of the air conditioning equipment.

[0096] 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 assembly is installed in the compressor chamber.

[0097] 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 assembly can be installed in the compressor cavity.

[0098] 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.
