[0002] In the related art, the compressor system of an outdoor unit of an air conditioner includes a compressor, a low-pressure tank, a gas-liquid separator, connecting pipelines, etc. The low-pressure tank is generally used to store a certain volume of refrigerant, and the gas-liquid separator is used to separate the gaseous refrigerant and the liquid refrigerant in the gaseous mixed refrigerant. Due to the unbalance of the rotor mass of the compressor, the inertial force and inertial moment caused by the high-speed rotation during the operation of the compressor cause the vibration of the compressor. Under the action of the periodic exciting force, the compressor is prone to fatigue failure, affecting the service life of the compressor. Summary of the Invention

[0037] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.

[0038] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing" and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0039] Although terms such as first, second, and third may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first" and "second" and other numerical terms used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

Therefore, the exemplary term "below" can include the upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0041] In the related art, the compressor system of an air conditioner outdoor unit includes a compressor, a low-pressure tank, a gas-liquid separator, connecting pipelines, etc. The low-pressure tank is generally used to store a certain volume of refrigerant, and the gas-liquid separator is used to separate the gaseous refrigerant and the liquid refrigerant in the gaseous mixed refrigerant. Due to the unbalanced mass of the compressor rotor, the inertial force and inertial moment caused by the high-speed rotation of the compressor during operation cause the vibration of the compressor. Under the action of the periodic excitation force, the compressor is prone to fatigue failure, affecting the service life of the compressor.

[0042] To this end, an embodiment of the present application provides a compressor integration system 10, which can effectively reduce the vibration of the compressor body, reduce the possibility of fatigue failure of the compressor, and improve the service life of the compressor.

[0043] Figure 1 It is a schematic structural diagram of the compressor integration system according to an embodiment of the present application. Figure 2 is Figure 1 a sectional view of the shown compressor integration system in the vertical plane.

[0044] Referring to Figure 1 and Figure 2 An embodiment of the present application provides a compressor integration system 10, including a housing 1, a compressor body 2, and a first vibration damping component 3.

[0045] The housing 1 has opposite top end 13 and bottom end 14 along its own height direction. The top end 13 is provided with spaced exhaust ports 11 and return air ports 12. The housing 1 may include a separately provided upper housing and a lower housing. The top end 13 may be the top end of the upper housing, and the bottom end 14 may be the bottom end of the lower housing.

[0046] The compressor body 2 is suspended in the housing 1, and the axial direction of the compressor body 2 is the same as the height direction of the housing 1. The compressor body 2 includes a tank body 21, an exhaust pipe 22 and a return air pipe 23. The tank body 21 includes a top cover 211, a cylindrical tank 212 and a bottom cover 213 arranged in sequence along its own axial direction. One end of the exhaust pipe 22 is connected to the top cover 211, and the other end of the exhaust pipe 22 extends out from the exhaust port 11. One end of the return air pipe 23 is connected to the cylindrical tank 212, and the other end of the return air pipe 23 is arranged at an interval from the return air port 12. The first vibration damping assembly 3 is connected between the cylindrical tank 212 and the inner wall of the housing 1.

[0047] In the related art, the low-pressure tank is generally used to store a certain volume of refrigerant refrigerant, with a volume of about 2L to 4L, and the gas-liquid separator is used to separate the gaseous refrigerant and the liquid refrigerant in the gaseous mixed refrigerant, with a volume of about 1L. In this embodiment, the housing 1 can integrate the gas-liquid separator and the low-pressure tank into one. The compressor body 2 is placed in the housing 1, and the volume of the housing 1 is about 4L to 5L. Or, the low-pressure tank is omitted, and the housing 1 is only used as the function of the gas-liquid separator, with a volume greater than 1L and less than 5L, or the size of the volume is determined according to the use scenario, as long as the housing 1 can accommodate the compressor body 2. Thus, in the embodiment of the present application, the compressor body 2, the gas-liquid separator, the low-pressure tank and the related pipelines are integrated in the housing 1, or the compressor body 2, the gas-liquid separator and the related pipelines are integrated in the housing 1. The housing 1 can shield most of the noise generated by the compressor body 2 during operation, with a compact structure and small occupied space.

[0048] Further, the compressor body 2 includes a tank body 21, an exhaust pipe 22 and a return air pipe 23. The tank body 21 includes a top cover 211, a cylindrical tank 212 and a bottom cover 213 arranged in sequence along its own axial direction. An exhaust joint 25 is arranged on the top cover 211. One end of the exhaust pipe 22 is connected to the exhaust joint 25, and the other end of the exhaust pipe 22 extends out from the exhaust port 11. A return air joint 26 is arranged at one end of the side wall of the cylindrical tank 212 close to the bottom cover 213. One end of the return air pipe 23 is connected to the return air joint 26, and the other end of the return air pipe 23 is arranged at an interval from the return air port 12. The low-temperature gas-liquid mixed refrigerant entering the inner cavity of the housing 1 from the return air port 12 is separated into gas and liquid under the action of its own gravity. Since the density of the gaseous refrigerant is less than that of the liquid refrigerant, the liquid refrigerant will fall to the bottom end 14 of the housing 1, while the low-temperature gaseous refrigerant remains on one side of the top end 13. The gaseous refrigerant is sucked into the compressor body 2 by the negative pressure of the return air pipe 23. A compression component is arranged in the tank body 21. The gas is compressed by the compression component to do work to generate high-temperature and high-pressure gaseous refrigerant, and then the high-temperature and high-pressure gaseous refrigerant is led out to the external circulation pipeline through the exhaust pipe 22 for subsequent refrigeration or heating cycle.

[0049] A compression component is arranged inside the tank body 21. The compression component includes a cylinder, a piston, a rotor, a stator, etc. Due to the unbalanced mass of the rotor, the inertial force and inertial moment generated by the high-speed rotation of the rotor during the compression of the gas by the compression component will cause vibration of the compressor body 2. In particular, the vibration received by the cylinder tank 212 part is relatively large. And the first vibration damping assembly 3 is connected between the cylinder tank 212 and the inner wall of the housing 1, so that the compressor body 2 is suspended inside the housing 1. The compressor body 2 is indirectly in contact with the housing 1 through the first vibration damping assembly 3, and most of the vibration generated when the compressor body 2 works can be dissipated through the first vibration damping assembly 3, and will not be completely and directly transmitted to the housing 1, thereby effectively reducing the vibration received by the entire compressor integrated system 10.

[0050] Optionally, a second return air pipe 27 can also be arranged at the return air port 12. One end of the second return air pipe 27 enters the housing 1, and the other end is located outside the return air port 12 and is communicated with other circulation pipelines. Since the end of the return air pipe 23 far from the cylinder tank 212 is isolated from the return air port 12 or the second return air pipe 27, the vibration transmitted from the compressor body 2 to the return air pipe 23 gradually dissipates and attenuates through the first vibration damping assembly 3, and will not transmit the vibration to the housing 1 through the return air pipe 23, avoiding the superposition of the vibration of the return air pipe 23 and the vibration of the compressor body 2, reducing the possibility of fatigue failure of the compressor body 2 under the action of periodic exciting force, and improving the service life of the compressor body 2.

[0051] According to the compressor integrated system 10 provided by the embodiment of the present application, by arranging the compressor body 2 inside the housing 1 for gas-liquid separation, a low-pressure tank and / or a gas-liquid separator in the related art can be integrated into one housing 1. The tank body 21 of the compressor body 2 includes a top cover 211, a cylinder tank 212 and a bottom cover 213 arranged in sequence along its own axis. One end of the exhaust pipe 22 is connected to the top cover 211, and the other end of the exhaust pipe 22 extends out from the exhaust port 11 at the top end 13 of the housing 1. One end of the return air pipe 23 is connected to the cylinder tank 212, and the other end of the return air pipe 23 is arranged at an interval from the return air port 12. The vibration received by the cylinder tank 212 part is relatively large. The first vibration damping assembly is connected between the cylinder tank 212 and the inner wall of the housing 1, so that the compressor body 2 is suspended inside the housing 1, and the first vibration damping assembly 3 can quickly dissipate most of the vibration generated when the compressor body 2 works, and will not completely and directly transmit the vibration of the compressor body 2 to the housing 1; the return air pipe 23 is arranged at an interval from the return air port 12, so that the vibration transmitted from the compressor body 2 to the return air pipe 23 can also be dissipated through the first vibration damping assembly 3 and will not be transmitted to the housing 1, thereby effectively reducing the vibration of the compressor integrated system 10, reducing the possibility of fatigue failure of the compressor body 2 under the action of periodic vibration excitation, and improving the service life of the compressor body 2.

[0052] In some embodiments, the first damping assembly 3 is connected between one end of the cylindrical tank 212 facing the top cover 211 and the inner wall of the housing 1, and the return air pipe 23 penetrates through the first damping assembly 3.

[0053] As Figure 2 shown, the housing 1 is basically a straight cylindrical structure, the tank body 2 of the compressor body 2 is a cylindrical structure, the tank body 21 includes a top cover 211, a cylindrical tank 212 and a bottom cover 213 arranged in sequence along its own axis. Exemplarily, the top cover 211, the cylindrical tank 212 and the bottom cover 213 are separately arranged; or, the top cover 211 and the cylindrical tank 212 are integrally formed and separately arranged from the bottom cover 213; or, the bottom cover 213 and the cylindrical tank 212 are integrally formed and separately arranged from the top cover 211. The inertial force and inertial moment generated by the high-speed rotation of the rotor of the compressor body 2 will cause vibration of the compressor body 2, resulting in vibration of the exhaust pipe 22 connected to the top cover 211 and the return air pipe 23 connected to the cylindrical tank 212. The first damping assembly 3 is connected between one end of the cylindrical tank 212 facing the top cover 211 and the inner wall of the housing 1, which can reduce the vibration received by the exhaust pipe 22 and the return air pipe 23, and is beneficial to improving the vibration stress of the exhaust pipe 22 and the return air pipe 23.

[0054] Figure 3 For Figure 2 a structural schematic diagram of a first damping assembly shown.

[0055] In some embodiments, the first damping assembly 3 includes a first damping member 31, a second damping member 32 and a plurality of elastic members 33. The first damping member 31 is connected to the cylindrical tank 212, the second damping member 32 is connected to the housing 1, and the plurality of elastic members 33 are arranged at intervals along the circumferential direction of the cylindrical tank 212, and the plurality of elastic members 33 are located between the first damping member 31 and the second damping member 32.

[0056] As Figure 3 shown, exemplarily, the top cover 211 of the tank body 21 is separately arranged from the cylindrical tank 212, the bottom cover 213 can be integrally formed with the cylindrical tank 212, and the bottom cover 213 can also be separately arranged from the cylindrical tank 212. The inner wall of the cylindrical tank 212 is fitted and welded to the outer wall of the top cover 211. The first damping member 31 and the second damping member 32 are arranged at intervals along the axis of the tank body 21. The first damping member 31 can be arranged on the first end face of the tank body 21 facing the top cover 211 and surround the outer wall of the top cover. At least one of the first end face of the tank body 21 and the outer wall of the top cover can be welded to the inner circumferential surface of the first damping member 31 to prevent the first damping member 31 from axially moving. At the same time, the outer circumferential surface of the second damping member 32 is welded to the inner wall of the housing 1, and the plurality of elastic members 33 are arranged at intervals along the circumferential direction of the tank body 21 and are located between the first damping member 31 and the second damping member 32. The elastic members 33 can be oil-resistant, refrigerant-resistant, high-temperature-resistant rubber pads or springs, etc. The plurality of elastic members 33 can be used to reduce the vibration generated by the compressor body 2.

[0057] In some embodiments, the first damping member 31 is a first annular member having a first notch 310, the second damping member 32 is a second annular member having a second notch 320, the elastic member 33 is disposed between the first annular member and the second annular member, and the return air pipe 23 passes through the first notch 310 and the second notch 320.

[0058] As Figure 3 shown, the first damping member 31 and the second damping member 32 are respectively annular plate members, and the two are arranged at intervals along the axial direction of the tank body 21. A first notch 310 is provided on one side of the first damping member 31, and a second notch 320 is provided on one side of the second damping member 32. The first damping member 31 can be disposed on the first end surface of the tank body 21 facing the top cover 211 and surround the outer wall of the top cover. At least one of the first end surface of the tank body 21 and the outer wall of the top cover can be welded to the inner peripheral surface of the first damping member 31 to prevent the first damping member 31 from moving axially. At the same time, the outer peripheral surface of the second damping member 32 is welded to the inner wall of the housing 1. A plurality of elastic members 33 are arranged at intervals along the circumferential direction of the tank body 21 and are located between the first damping member 31 and the second damping member 32. The elastic members 33 can be oil-resistant, refrigerant-resistant, and high-temperature-resistant rubber pads or springs, etc. The plurality of elastic members 33 can be used to reduce the vibration generated by the compressor body 2.

[0059] On the one hand, the first notch 310 and the second notch 320 can be used to avoid the return air pipe 23. After passing through the first notch 310 and the second notch 320, the return air pipe 23 extends toward the top end 13. On the other hand, the liquid refrigerant separated from the mixed refrigerant entering the housing 1 from the return air port 12 of the housing 1 can flow through the first notch 310 and the second notch 320 to the bottom end 14 side under the action of its own gravity, while the gaseous refrigerant floats in the space above the first damping member 31 for the return air pipe 23 to suck in, achieving the effect of gas-liquid separation.

[0060] Figure 4 For Figure 2 the structural schematic diagram of another first damping assembly shown.

[0061] In some embodiments, the first damping member 31 includes a first annular portion 311 and a plurality of first connecting portions 312 distributed at intervals along the outer periphery of the first annular portion 311. The first annular portion 311 is connected to the cylinder tank 212; the second damping member 32 includes a second annular portion 321 and a plurality of second connecting portions 322 distributed at intervals along the inner periphery of the second annular portion 321. The second annular portion 321 is connected to the housing 1, and the elastic member 33 is disposed between the first connecting portion 312 and the second connecting portion 322; the return air pipe 23 passes through the gap between the first annular portion 311 and the second annular portion 321.

[0062] As Figure 4As shown, the first annular portion 311 and the second annular portion 321 are respectively annular rings, and the two are arranged at intervals along the axial direction of the tank body 21. The first annular portion 311 can be arranged on the first end face of the tank body 21 facing the top cover 211 and surround the outer wall of the top cover. At least one of the first end face of the tank body 21 and the outer wall of the top cover can be welded to the inner circumferential surface of the first annular portion 311 to prevent the first vibration damping member 31 from moving axially. At the same time, the outer circumferential surface of the second annular portion 321 is welded to the inner wall of the housing 1. The first connecting portion 312 and the second connecting portion 322 are respectively trapezoidal plates or triangular plates. The three first connecting portions 312 are distributed at intervals along the outer circumference of the first annular portion 311, and the three second connecting portions 322 are distributed at intervals along the inner circumference of the second annular portion 321. The three elastic members 33 are arranged at intervals along the circumferential direction of the tank body 21 and are located between the first connecting portion 312 and the second connecting portion 322. The elastic member 33 can be an oil-resistant, refrigerant-resistant, high-temperature-resistant rubber pad or a spring, etc. The elastic member 33 can be used to reduce the vibration generated by the compressor body 2.

[0063] Thus, three relatively large gaps are formed between the first annular portion 311 and the second annular portion 321, facilitating the liquid refrigerant separated from the mixed refrigerant to quickly flow to the bottom end 14 of the housing 1 under the action of its own gravity, improving the efficiency of gas-liquid separation. At the same time, the return air pipe 23 can also pass through the gap and extend towards the top end 13.

[0065] Refer to Figure 5 , the compressor integration system 10 provided by the embodiment of the present application is similar in structure to the compressor integration system 10 shown in Figure 1 and Figure 2 . The difference is that the first vibration damping assembly 3 is connected between the middle part of the barrel tank 212 and the inner wall of the housing 1, and the structure of the first vibration damping assembly 3 can be any one of the first vibration damping assemblies 3 shown in Figure 3 and Figure 4 .

[0066] In this embodiment, the middle part of the barrel tank 212 refers to the middle area in the length direction of the barrel tank 212. When the inertial force and inertial moment generated by the high-speed rotation of the rotor of the compressor body 2 cause the vibration of the compressor body 2, the first vibration damping assembly 3 is connected between the middle part of the barrel tank 212 and the inner wall of the housing 1, so that the swing on the side of the top cover 211 of the tank body 21 and the swing on the side of the bottom cover 213 are similar, and thus the overall swing of the compressor integration system 10 is more stable and reliable.

[0067] Figure 6 It is a sectional view of the compressor integration system according to another embodiment of the present application in a vertical plane.

[0068] Referring to Figure 6 , the compressor integration system 10 provided in the embodiment of the present application is similar in structure to the compressor integration system 10 shown in Figure 1 and Figure 2 . The difference is that the first vibration damping component 3 is connected between one end of the barrel 212 facing the bottom cover 213 and the inner wall of the housing 1. The return air pipe 23 may or may not pass through the first vibration damping component 3, depending on the structure of the return air pipe 23.

[0069] The structure of the first vibration damping component 3 can be any one of the first vibration damping components 3 shown in Figure 3 and Figure 4 .

[0070] In this embodiment, the compression component is located in the accommodation space formed by the barrel 212 and the bottom cover 213 of the tank body 21. When the inertial force and inertial moment generated by the high-speed rotation of the rotor of the compressor body 2 cause vibration of the compressor body 2, the bottom cover 213 and the bottom area of the barrel 212 vibrate greatly. The first vibration damping component 3 is connected between one end of the barrel 212 facing the bottom cover 213 and the inner wall of the housing 1, which can reduce the overall swing of the compressor integration system 10 from the root cause.

[0071] In some embodiments, a connecting member 24 is provided on the side surface of the barrel 212, and the connecting member 24 is connected to one end of the return air pipe 23.

[0072] As shown in Figure 2 , Figure 5 , Figure 6 , a connecting member 24 may be provided on the side surface of the barrel 212 of the compressor body 2. One end of the connecting member 24 is connected to the side surface of the barrel 212, and the other end of the connecting member 24 surrounds one end of the return air pipe 23 to further reduce the vibration of the return air pipe 23. The shape of the connecting member 24 is not limited as long as it can fix a section of the return air pipe 23. One end of the connecting member 24 may be welded to the side surface of the tank body 21, or one end of the connecting member 24 may be connected to the side surface of the tank body 21 through fasteners such as screws and pins. The threaded hole or pin hole of the tank body 21 is a blind hole to ensure the airtightness of the tank body 21.

[0073] In some embodiments, a rib 214 extending along its own axis is provided on the outer wall of the barrel 212. The first vibration damping member 31 is provided with a first groove 313 for cooperating with the rib 214, and the second vibration damping member 32 is provided with a second groove 323 for cooperating with the rib 214.

[0074] As shown in Figure 3 , Figure 4 and Figure 5As shown, the cylindrical tank 212 can be formed by winding a sheet material and welded into a cylindrical shape through a weld seam. The weld seam can extend axially along the outer circumference of the tank body 21, and a rib 214 can be formed at the weld seam. Since the vibration of the compressor body 2 in the tangential direction is relatively large, ribs 214 extending along its own axis are provided on the outer circumference of the tank body 21. The first groove 313 of the first shock absorber 31 and the second groove 323 of the second shock absorber 32 are respectively engaged with the rib 214, so as to prevent the first shock absorber assembly 3 from sliding along the outer circumference of the tank body 21, increase the friction force between the first shock absorber assembly 3 and the outer circumference of the tank body 21, and thus improve the shock absorption effect of the first shock absorber assembly 3.

[0075] Figure 7 For Figure 1 the structural schematic diagram of the compressor integrated system shown after hiding part of the housing.

[0076] In some embodiments, an oil sump 15 is provided at the bottom end 14 of the housing 1. The compressor integrated system 10 further includes an oil return capillary 5. One end of the oil return capillary 5 is communicated with the return air pipe 23, and the other end of the oil return capillary 5 extends into the oil sump 15; alternatively, an oil return hole is provided on the side of the return air pipe 23 facing the bottom end 14, and the oil return hole is located within the liquid level of the oil sump 15.

[0077] As Figure 7 shown, exemplarily, the shape of the return air pipe 23 is similar to the letter "F", which includes a main pipe and two branch pipes provided at one end of the main pipe. The two branch pipes are arranged on the same side and are respectively communicated with a return air joint. An oil sump 15 is provided at the bottom end 14 of the housing 1, and the engine oil in the oil sump 15 is used to lubricate components such as the rotor of the cylinder assembly. During the process of the compressor body 2 discharging high-temperature and high-pressure gaseous refrigerant, it inevitably takes away some mist-like engine oil, resulting in a reduction in the engine oil in the compressor body 2. If there is too much engine oil in the refrigerant in the circulation loop, it may cause a decrease in the refrigeration capacity of the system. For this reason, in this embodiment, two oil return capillaries 5 are added. Oil holes are respectively provided on the two branch pipes. One end of the oil return capillary 5 is connected to the oil hole of one branch pipe, and the other end of the oil return capillary 5 extends into the oil sump 15 at the bottom end 14 of the housing 1. In this way, in the gas-liquid mixed refrigerant entering from the return air port 12, the density of the engine oil is greater than that of the liquid refrigerant, and the density of the liquid refrigerant is greater than that of the gaseous refrigerant. Therefore, the refrigerant will separate the engine oil, liquid refrigerant and gaseous refrigerant by stratification under the action of its own gravity, and the engine oil will fall into the oil sump 15 at the bottom layer of the housing 1. The oil return capillary 5 can introduce the engine oil in the oil sump into the compressor body 2 through the return air pipe 23 for oil replenishment, realizing the recycling of the engine oil. The diameter of the oil return capillary 5 is generally 0.5 mm to 1.5 mm. Compared with adding a separate oil return device in the related art, the oil return capillary 5 realizes the oil separation function while reducing the manufacturing cost and improving the integration degree of the system.

[0078] In other examples, one end of the return air pipe 23 far from the cylinder tank 212 bends toward the top end 13 after passing through the oil sump 15, continues to extend toward the top end 13 after passing through the first damping component 3, and an oil return hole is provided on the side of the return air pipe 23 facing the bottom end 14. The oil return hole is located within the liquid level of the oil sump 15. The oil return hole can introduce the engine oil in the oil sump into the compressor body 2 for oil replenishment, realizing the recycling of the engine oil. Since the oil return capillary 5 is omitted, the manufacturing cost can be saved.

[0079] In some embodiments, the exhaust pipe 22 includes a plurality of pipe segments sequentially connected within the space between the outer wall of the tank body 21 and the inner wall of the housing 1. Adjacent two pipe segments bend at a preset angle, one of the pipe segments is connected to the top cover 211, and the other pipe segment extends out from the exhaust port 11. At least part of the pipe segments pass through the first damping component 3.

[0080] As Figure 7 shown, the exhaust pipe 22 has five sequentially connected pipe segments, and adjacent two pipe segments are bent at 90°. Thus, the exhaust pipe 22 has high flexibility in structure, and the vibration received by the exhaust pipe 22 is dissipated through the movement between the pipe segments, reducing the vibration stress and improving the service life.

[0081] Figure 8 is an exploded structural schematic diagram of an outdoor unit of an air conditioner according to an embodiment of the present application.

[0082] Refer to Figure 8 , an embodiment of the present application provides an outdoor unit 100 of an air conditioner, including a chassis 20, a compressor integration system 10 according to an embodiment of the present application, and a second damping component 4. The compressor integration system 10 is disposed on the chassis 20, and the second damping component 4 is disposed between the chassis 20 and the inner wall of the housing 1 of the compressor integration system 10.

[0083] The outdoor unit 100 of the air conditioner further includes an outdoor heat exchanger 40, a blower 50, a four-way valve 6, a circulation loop, etc. disposed on the chassis 20. The second damping component 4 is disposed between the chassis 20 and the inner wall of the housing 1 of the compressor integration system 10, which can further reduce the vibration of the compressor integration system 10, and further reduce the vibration of the outdoor unit 100 of the air conditioner.

[0084] In some embodiments, the second damping component 4 includes a support member 41 and a flexible pad 42. The support member 41 is connected to the bottom end 14 of the housing 1 or the side wall near the bottom end 14, and the flexible pad 42 is disposed between the chassis 20 and the support member 41.

[0085] As Figure 8As shown, the support member 41 of the second shock-absorbing assembly 4 can be in various forms such as an annular plate member, a frame structure, etc. It can be welded to the bottom end 14 of the housing 1 or to the side wall of the housing 1 near the bottom end 14. A plurality of flexible pads 42 are located between the chassis 20 and the support member 41. The flexible pads 42 can be rubber pads or springs that are resistant to oil, refrigerant, and high temperature, and are used to reduce the vibration and noise of the compressor integration system 10. Optionally, nuts of a plurality of screws are embedded in the chassis 20, and the screw rods of the screws sequentially pass through the flexible pads 42 and the support member 41 and are threadedly connected to the screw rods through nuts.

[0086] Figure 9 It is a schematic electrical structure diagram of the heating, ventilation, and air conditioning (HVAC) equipment according to an embodiment of the present application.

[0087] Refer to Figure 9 , an embodiment of the present application provides a HVAC equipment 1000, including an air conditioner indoor unit 200 and the air conditioner outdoor unit 100 of the embodiment of the present application. The air conditioner outdoor unit 100 is connected to the air conditioner indoor unit 200 through a pipeline.

[0088] The air conditioner indoor unit 200 is installed indoors, and the air conditioner outdoor unit 100 is installed outdoors for refrigeration or heating, and transports refrigerant through a pipeline. The refrigerant exchanges heat with the indoor air and the outdoor air respectively. The air conditioner indoor unit 200 is used to deliver cold air or hot air into the room to achieve the effect of cooling or heating.

[0089] As Figure 8 and Figure 9 shown, the four-way valve 6 includes a first valve port 61, a second valve port 62, a third valve port 63, and a fourth valve port 64. The first valve port 61 is communicated with the exhaust pipe 22 of the compressor body 2, the third valve port 63 is communicated with the second return pipe 27 of the compressor body 2, the second valve port 62 is communicated with the inlet of the outdoor heat exchanger 40, and the fourth valve port 64 is communicated with the outlet of the indoor heat exchanger 210.

[0090] Thus, the four-way valve 6 has two working states: when the four-way valve 6 is powered off, the HVAC equipment 1000 operates normally and enters the refrigeration cycle mode. At this time, the first valve port 61 can be communicated with the second valve port 62, and the third valve port 63 is communicated with the fourth valve port 64, and the refrigerant flows in a first direction in the circulation loop. After the refrigerant is discharged from the exhaust pipe 22 of the compressor body 2, it sequentially flows through the outdoor heat exchanger 40 of the air conditioner outdoor unit 100 and the indoor heat exchanger 210 of the air conditioner outdoor unit 100 through the four-way valve 6. At this time, the outdoor heat exchanger 40 is used as a condenser to condense the high-temperature and high-pressure refrigerant discharged from the compressor body 2, and the fan 50 can improve the heat exchange efficiency of the outdoor heat exchanger 40. The indoor heat exchanger 210 is used as an evaporator, and exchanges heat with the indoor air through the low-temperature refrigerant, so as to output cold air into the room. Then the refrigerant flows back to the compressor body 2 through the second return pipe 27 and the return pipe 23.

[0091] When the four-way valve 6 is energized, the heating and ventilation equipment 1000 enters the defrosting cycle mode. At this time, the first valve port 61 can communicate with the fourth valve port 64, and the second valve port 62 communicates with the third valve port 63. The refrigerant flows in the second direction in the circulation loop, and the second direction is opposite to the first direction. After the refrigerant is discharged from the exhaust pipe 22 of the compressor body 2, it flows through the four-way valve 6 to the indoor heat exchanger 210 and the outdoor heat exchanger 40 in sequence. At this time, the indoor heat exchanger 210 is used as a condenser. The high-temperature and high-pressure refrigerant discharged from the exhaust pipe 22 of the compressor body 2 exchanges heat with the indoor heat exchanger 210, thereby outputting warm air to the indoor. The outdoor heat exchanger 40 is used as an evaporator. Then, the refrigerant returns to the compressor body 2 through the second return pipe 27 and the return pipe 23.

[0092] For the air conditioner outdoor unit 100 and the heating and ventilation equipment 1000 provided by the embodiments of the present application, by adopting the compressor integration system 10 of the embodiments of the present application, the first damping component 3 provided between the cylinder 212 of the compressor body 2 and the inner wall of the housing 1 can effectively reduce the vibration of the compressor integration system 10. The second damping component 4 provided between the housing 1 of the compressor integration system 10 and the chassis 20 further reduces the vibration of the compressor integration system 10, reduces the possibility of fatigue failure of the compressor body 2 under the action of periodic vibration excitation, and improves the service life of the compressor body 2.
