[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 unbalanced mass of the rotor of the compressor, the inertial force and inertial moment generated by the high-speed rotation of the rotor during the operation of the compressor will cause the vibration of the compressor. In severe cases, harsh noises will be generated, affecting the user experience. Summary of the Invention

[0038] 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 completely conveyed to those skilled in the art.

[0039] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates 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. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order described or illustrated, unless the order of performance is expressly stated. It should also be understood that additional or alternative steps may be used.

[0040] Although the terms first, second, third, etc. 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 be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly dictates otherwise, terms such as "first", "second", and other numerical terms when used herein do not imply an order or sequence. Thus, a first element, component, region, layer, or section discussed below may be referred to as a second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0041] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature to another element or feature as shown in the figures, such as "inner", "outer", "inside", "outside", "below", "beneath", "above", "over", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as "below" or "beneath" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the example term "below" can include both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatial relative descriptors used herein are to be interpreted accordingly.

[0042] 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 generated by the high-speed rotation of the rotor during the operation of the compressor will cause the vibration of the compressor. In severe cases, harsh noises will be generated, affecting the user experience.

[0043] Therefore, an embodiment of the present application provides a compressor integrated system 10, which integrates a compressor, a liquid storage device, a gas-liquid separator and connecting pipelines into one body to form the compressor integrated system 10. The structure is compact and occupies a small space, which can effectively reduce the vibration received by the compressor body, reduce the vibration noise, and improve the user experience.

[0044] Figure 1 It is a schematic structural diagram of a compressor integrated system according to an embodiment of the present application. Figure 2 is Figure 1 a sectional view of the shown compressor integrated system.

[0045] Referring to Figure 1 and Figure 2 An embodiment of the present application provides a compressor integrated system 10, which includes a housing 1, a compressor body 2 and a first vibration damping component 3.

[0046] The housing 1 has opposite top end 13 and bottom end 14 along its own height direction, and the top end 13 is provided with an exhaust port 11 and a return air port 12 which are distributed at intervals.

[0047] The compressor body 2 is suspended in 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 is provided with an exhaust joint 211 and a return air joint 212 which are distributed at intervals. One end of the exhaust pipe 22 is connected to the exhaust joint 211, and the other end extends out from the exhaust port 11. One end of the return air pipe 23 is connected to the return air joint 212, and the first vibration damping component 3 is connected between the tank body 21 and the housing 1.

[0048] In the related art, a low-pressure tank is generally used to store a refrigerant refrigerant with a certain volume, about 2L to 4L, and a 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 body. The compressor body 2 is placed in the housing 1, and the volume of the housing 1 is about 4L to 5L. Alternatively, 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.

[0049] Furthermore, the compressor body 2 further includes a compression component disposed in the tank body 21. The compression component compresses the gas to do work to generate high-temperature and high-pressure gaseous refrigerant, and leads the high-temperature and high-pressure gaseous refrigerant to the external circulation pipeline through the exhaust pipe 22. Due to the unbalanced mass of the rotor of the compression component, 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 the vibration of the compressor body 2. The compressor body 2 is indirectly in contact with the housing 1 through the first vibration damping component 3, and the vibration generated during operation can be dissipated through the first vibration damping component 3 and will not be directly transmitted to the housing 1, thereby effectively reducing the vibration received by the compressor body 2, reducing the vibration noise, and improving the user experience.

[0050] In addition, the first vibration damping component 3 is connected between the tank body 21 and the housing 1. The low-temperature gas-liquid mixed refrigerant entering the inner cavity of the housing 1 from the suction 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 one side of the bottom end 14 of the housing 1, while the gaseous refrigerant remains on the top end 13 side. The gaseous refrigerant is sucked into the compressor body 2 by the negative pressure of the suction pipe 23 to perform compression work, generating high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant is discharged from the exhaust port 11 through the exhaust pipe 22 to the circulation pipeline outside the housing 1 for subsequent refrigeration or heating cycle.

[0051] Optionally, a second return air pipe 25 may be provided at the return air port 12. One end of the second return air pipe 25 enters the housing 1, and the other end is located outside the return air port 12 and communicates with other circulation pipelines. Since the end of the return air pipe 23 away from the return air joint 212 is isolated from the return air port 12 or the second return air pipe 25, 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 the vibration will not be transmitted 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. Thus, the low-frequency vibration and noise of the compressor body 2 can be greatly reduced, the user's listening experience can be improved, and the user's use experience can be enhanced.

[0052] According to the compressor integration system 10 provided by the embodiment of the present application, by suspending the compressor body 2 in the housing 1 for gas-liquid separation, and at the same time arranging the first vibration damping assembly 3 between the tank body 21 of the compressor body 2 and the housing 1. Since the compressor body 2 and the housing 1 are indirectly in contact through the first vibration damping assembly 3, the vibration generated when the compressor body 2 operates dissipates through the first vibration damping assembly 3. The end of the return air pipe 23 away from the return air joint 212 is isolated from the return air port 12 and will not directly transmit the vibration to the housing 1 through the return air pipe 23. The housing 1 can also shield the vibration noise generated when the compressor body 2 operates. Thus, the vibration received by the compressor body 2 can be effectively reduced, the vibration noise can be lowered, and the user's use experience can be improved.

[0053] In some embodiments, the housing 1 includes a first segment 1a, a second segment 1b arranged in sequence along the direction from the top end 13 to the bottom end 14, and a step portion 1c connecting the first segment 1a and the second segment 1b. The outer diameter of the first segment 1a is larger than the outer diameter of the second segment 1b, and the first vibration damping assembly 3 is connected between the step portion 1c and the tank body 21.

[0054] As Figure 2 shown, the housing 1 is a "thicker at the top and thinner at the bottom" cylindrical body, that is, the outer diameter of the first segment 1a is larger than the outer diameter of the second segment 1b. The first segment 1a and the second segment 1b are connected by the step portion 1c. The step portion 1c can be located in the upper part or the middle part of the housing 1, that is, at a position within the range of 1 / 3 to 2 / 3 of the housing 1 along its own height direction. The step portion 1c is used to fix and support the first vibration damping assembly 3. 1a1c1b1c

[0055] Figure 3 For Figure 1 the exploded structural schematic diagram of the first vibration damping assembly and the compressor body in the shown compressor integration system.

[0056] In some embodiments, the first vibration damping assembly 3 includes a first vibration damping member 31 and a plurality of elastic members 33. The first vibration damping member 31 surrounds the outer periphery of the tank body 21 and is welded to the tank body 21. The plurality of elastic members 33 are arranged at intervals along the circumferential direction of the first vibration damping member 31, and the plurality of elastic members 33 are located between the step portion 1c and the first vibration damping member 31. The first vibration damping member 31 is provided with a notch 3a, and the return air pipe 23 passes through the notch 3a.

[0057] As Figure 3 shown, the first vibration damping member 31 is sleeved on the outer periphery of the tank body 21, and the inner surface of the first vibration damping member 31 is welded to the outer peripheral surface of the tank body 21. The plurality of elastic members 33 are located between the step portion 1c and the first vibration damping member 31. The elastic members 33 can be oil-resistant, refrigerant-resistant, and high-temperature-resistant rubber pads or springs, etc., for reducing the vibration generated by the compressor body 2. Optionally, nuts of a plurality of screws are embedded in the step portion 1c, and the screw rods of the screws sequentially pass through the elastic members 33 and the first vibration damping member 31 and are threadedly connected to the screw rods through nuts. The plurality of elastic members 33 are arranged at intervals along the circumferential direction of the first vibration damping member 31, which can ensure that the compressor body 2 is evenly stressed. The first vibration damping member 31 can be provided with a plurality of notches 3a, and the plurality of notches 3a are arranged at intervals along the circumferential direction of the first vibration damping member 31. The return air pipe 23 passes through one of the notches 3a to suck the gaseous refrigerant into the tank body 21 through negative pressure. At the same time, the liquid refrigerant in the mixed refrigerant entering from the return air port 12 of the housing 1 enters the side of the bottom end 14 through the plurality of notches 3a under the action of its own gravity, achieving the effect of gas-liquid separation.

[0058] In some embodiments, the outer periphery of the tank body 21 is provided with a rib 213 extending along its own axis, and the first vibration damping member 31 is provided with a first groove 311 that cooperates with the rib 213.

[0059] As Figure 3 shown, the tank body 21 can be formed by winding a plate and welded into a cylindrical shape by a weld seam. The weld seam can extend along the axis of the outer periphery of the tank body 21, and the weld seam can be formed into a rib 213. Since the vibration of the compressor body 2 in the tangential direction is relatively large, the outer periphery of the tank body 21 is provided with a rib 213 extending along its own axis, and the first groove 311 of the first vibration damping member 31 cooperates with the rib 213, so that the first vibration damping member 31 can be prevented from sliding along the outer periphery of the tank body 21, increasing the friction force between the first vibration damping assembly 3 and the outer periphery of the tank body 21, and further improving the vibration damping effect of the first vibration damping assembly 3.

[0060] In some embodiments, the housing 1 includes a first sub-housing 15 and a second sub-housing 16 connected to each other along the direction from the top end 13 to the bottom end 14. The first sub-housing 15 includes a first segment 1a, a step portion 1c, and a part of the second segment 1b, and the second sub-housing 16 includes another part of the second segment 1b.

[0061] As Figure 2As shown, for the convenience of manufacturing the housing 1, the first sub-housing 15 includes a first segment 1a and a stepped portion 1c, and the second sub-housing 16 includes a second segment 1b. The first sub-housing 15 and the second sub-housing 16 are connected by welding to ensure the tightness of the housing 1. Since the connection between the first sub-housing 15 and the second sub-housing 16 avoids the stepped portion 1c, on the one hand, it will not affect the vibration damping effect of the first vibration damping assembly 3, and on the other hand, it can also prevent problems such as cracking at the connection between the first sub-housing 15 and the second sub-housing 16 due to vibration.

[0062] Figure 4 The structural schematic diagram of the compressor integrated system according to another embodiment of the present application Figure 5 is Figure 4 the sectional view of the compressor integrated system shown Figure 6 is Figure 4 the exploded structural schematic diagram of the first vibration damping assembly and the compressor body in the compressor integrated system shown.

[0063] In some embodiments, the first vibration damping assembly 3 includes a first vibration damping member 31, a second vibration damping member 32, and a plurality of elastic members 33. The first vibration damping member 31 surrounds the outer periphery of the tank body 21 and is welded to the outer wall of the tank body 21. The second vibration damping member 32 surrounds the inner periphery of the housing 1 and is welded to the inner wall of the housing 1. The plurality of elastic members 33 are arranged at intervals along the circumferential direction of the tank body 21, and the plurality of elastic members 33 are located between the first vibration damping member 31 and the second vibration damping member 32. The first vibration damping member 31 and the second vibration damping member 32 are respectively provided with notches 3a, and one end of the return air pipe 23 far from the return air joint 212 respectively passes through the notch 3a of the first vibration damping member 31 and the notch 3a of the second vibration damping member 32.

[0064] As Figures 4 to 6 shown, the housing 1 is basically a straight cylindrical structure, which may include a cylinder body, a cover plate, and a bottom shell that are separately arranged. The top end 13 may be one end of the top surface of the cover shell covering the cylinder body, and the bottom end 14 may be one end of the bottom surface of the bottom shell covering the cylinder body. The cylinder body and the cover shell may also be an integral structure, and the top end 13 is the top surface end of the cylinder body. The cylinder body and the bottom shell may also be an integral structure, and the bottom end 14 is the bottom surface end of the cylinder body.

[0065] The first vibration damping assembly 3 includes a first vibration damping member 31, a second vibration damping member 32, and a plurality of elastic members 33. The first vibration damping member 31 surrounds the outer periphery of the tank body 21, and the inner surface of the first vibration damping member 31 is welded to the outer wall of the tank body 21. The second vibration damping member 32 surrounds the inner periphery of the housing 1, and the outer surface of the second vibration damping member 32 is welded to the inner wall of the housing 1. 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 vibration damping member 31 and the second vibration damping member 32. The elastic member 33 may be an oil-resistant, refrigerant-resistant, and high-temperature-resistant rubber pad or a spring, etc., for reducing the vibration generated by the compressor body 2.

[0066] The notches 3a of the first vibration damping member 31 and the notches 3a of the second vibration damping member 32 can be multiple respectively. The notches 3a of the first vibration damping member 31 and the notches 3a of the second vibration damping member 32 are used to at least avoid the return air pipe 23 on one hand, so as to prevent the vibration of the return air pipe 23 from being superimposed on the vibration of the compressor body 2 and improve the vibration suppression effect. On the other hand, the liquid refrigerant separated from the mixed refrigerant entering from the return air port 12 of the housing 1 can enter the side of the bottom end 14 through the multiple notches 3a under the action of its own gravity, achieving the effect of gas-liquid separation.

[0067] In some embodiments, a rib 213 extending along its own axis is provided on the outer periphery of the tank body 21. The first vibration damping member 31 is provided with a first groove 311 that cooperates with the rib 213, and the second vibration damping member 32 is provided with a second groove 321 that cooperates with the rib 213.

[0068] As Figure 6 shown, the tank body 21 can be formed by winding a sheet and welded into a cylindrical shape by a weld seam. The weld seam can extend axially along the outer periphery of the tank body 21, and the weld seam can be formed into the rib 213. Since the vibration of the compressor body 2 in the tangential direction is relatively large, a rib 213 extending along its own axis is provided on the outer periphery of the tank body 21, and the first groove 311 of the first vibration damping member 31 and the second groove 321 of the second vibration damping member 32 cooperate with the rib 213 respectively, so as to prevent the first vibration damping assembly 3 from sliding along the outer periphery of the tank body 21, increase the friction force between the first vibration damping assembly 3 and the outer periphery of the tank body 21, and further improve the vibration damping effect of the first vibration damping assembly 3.

[0069] In some embodiments, a connecting member 24 is further provided between the side surface of the compressor body 2 and the notch 3a. The connecting member 24 is connected to one end of the return air pipe 23 far from the return air joint 212.

[0070] As Figure 2 and Figure 6 shown, a connecting member 24 can be provided on the side surface of the tank body 21 of the compressor body 2. One end of the connecting member 24 is connected to the side surface of the tank body 21, and the other end of the connecting member 24 surrounds the outer periphery of one end of the return air pipe 23 far from the return air joint 212, further reducing the vibration of the return air pipe 23 and reducing the noise. 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 can be welded to the side surface of the tank body 21, and one end of the connecting member 24 can also 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.

[0071] 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 pipe segments are bent at a preset angle. One pipe segment is connected to the exhaust joint 211, and the other pipe segment extends out from the exhaust port 11. The exhaust pipe 22 passes through the first vibration damping assembly 3.

[0072] As Figure 6 shown, exemplarily, the exhaust pipe 22 has a plurality of pipe segments sequentially connected. Adjacent pipe segments are bent at a 90° angle, so that the exhaust pipe 22 has high flexibility in structure. The material can be a metal pipe, which can absorb the vibration received by the exhaust pipe 22, reduce the vibration stress, and at the same time can also have a certain structural strength to prevent being scratched during transportation or use and affecting the service life. The material of the exhaust pipe 22 can also be a combination of multiple materials. When the compressor body 2 operates, the tangential vibration is relatively large. Among them, the pipe segment of the exhaust pipe 22 parallel to the axial direction of the compressor body 2 receives relatively large vibration stress, and its material can be set as a metal braided hose, which can greatly reduce the vibration stress; the remaining pipe segments parallel to the bottom end 14 of the housing 1 receive relatively small vibration stress and can be made of copper pipes or stainless steel pipes. Since the cost of the metal braided hose is higher than that of the ordinary metal pipe, in this embodiment, the metal braided hose and the ordinary metal pipe are used in combination, which can not only reduce the vibration stress of the exhaust pipe 22, but also save the manufacturing cost.

[0073] In some embodiments, the compressor body 2 includes a rotor and a stator disposed within the tank body 21. The number of rotors is one or two, and the number of rotors is the same as the number of suction joints 212.

[0074] Generally, a compression chamber and an inlet and an outlet communicating with the compression chamber are provided within the tank body 21 of the compressor body 2. The inlet communicates with the suction joint 212, and the outlet communicates with the exhaust pipe 22. A rotor and a piston (not shown in the figure) are disposed within the compression chamber. The rotor is used to drive the piston to compress the gas to do work, so as to compress the low-temperature and low-pressure gaseous refrigerant inhaled from the inlet into a high-temperature and high-pressure gaseous refrigerant and discharge the high-temperature and high-pressure gaseous refrigerant from the outlet to the exhaust pipe 22. One compression chamber and one rotor can be provided within the tank body 21, and correspondingly, the number of suction joints 212 is one. Two compression chambers and two rotors can also be provided within the tank body 21, with one rotor disposed within each compression chamber. Correspondingly, the number of suction joints 212 is two. For the compressor body 2 with two rotors, the two rotors operate alternately within their respective compression chambers, so as to continuously compress the gaseous refrigerant and improve the energy efficiency of the compressor body 2. The number of rotors and the number of suction joints 212 are specifically determined according to the volume and power of the compressor body 2, which will not be elaborated here.

[0075] In some embodiments, the number of the return air connectors 212 is two, and the two return air connectors 212 are arranged at intervals in the height direction on the side surface of the tank body 21. One return air pipe 23 is connected to both of the two return air connectors 212.

[0076] In one example, as Figure 2 and Figure 5 shown, the return air pipe 23 is arranged in an "F" shape. The two return air connectors 212 are arranged at intervals in the height direction on the side surface of the tank body 21. One return air pipe 23 is connected to both of the two return air connectors 212. In another example, the numbers of the return air connectors 212 and the return air pipes 23 are two respectively. The two return air connectors 212 are arranged at intervals in the height direction on the side surface of the tank body 21. The two return air pipes 23 are arranged in parallel. One return air pipe 23 is connected to one return air connector 212. The low-temperature gaseous refrigerant inhaled from the return air pipe 23 enters the two compression chambers in the compressor body 2 through the two return air connectors 212 at the same time. The two compression chambers of the compressor body 2 alternately and independently suck air from the corresponding return air pipe 23 for compression work, realizing continuous compression operation and improving the energy efficiency of the compressor body 2.

[0077] Figure 7 is a schematic structural diagram of an outdoor unit of an air conditioner according to an embodiment of the present application, Figure 8 is Figure 7 an enlarged structural diagram of area M in

[0078] Referring to Figure 7 and Figure 8 , an embodiment of the present application provides an outdoor unit 100 of an air conditioner, including the compressor integration system 10 of the embodiment of the present application. The outdoor unit 100 of the air conditioner further includes a chassis 20 and an outdoor heat exchanger 40, a fan 50, a four-way valve 8, a circulation loop, etc. arranged on the chassis 20.

[0079] In some embodiments, the outdoor unit 100 of the air conditioner further includes a second vibration damping component 30, and the second vibration damping component 30 is arranged between the chassis 20 and the housing 1 of the compressor integration system 10. The second vibration damping component 30 can reduce the vibration generated by the compressor integration system 10, avoid transmitting the vibration of the compressor body 2 to other components such as the outdoor heat exchanger 40 and the fan 50 through the chassis 20, and improve the service life of the outdoor unit 100 of the air conditioner.

[0080] In some embodiments, the second vibration damping component 30 includes a support member 301 and a flexible pad 302. The support member 301 is connected to the bottom end 14 of the housing 1 or the side wall near the bottom end 14, and the flexible pad 302 is arranged between the chassis 20 and the support member 301.

[0081] Such as Figure 8As shown, the support member 301 of the second shock-absorbing assembly 30 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 302 are located between the chassis 20 and the support member 301. The flexible pads 302 can be rubber pads or springs that are oil-resistant, refrigerant-resistant, and high-temperature-resistant, 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 302 and the support member 301 and are threadedly connected to the screw rods through nuts.

[0082] In addition, the volume of the housing 1 in the compressor integration system 10 can be very large. On the one hand, it can store more refrigerant, and on the other hand, as a web with a large mass, it can improve the anti-deformation stiffness of the system and further reduce the vibration and noise received by the air conditioner outdoor unit 100.

[0083] Figure 9 It is a schematic electrical structure diagram of the heating, ventilation, and air conditioning equipment according to an embodiment of the present application.

[0084] Refer to Figure 9 , an embodiment of the present application provides a heating, ventilation, and air conditioning 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.

[0085] 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.

[0086] The four-way valve 8 includes a first valve port 81, a second valve port 82, a third valve port 83, and a fourth valve port 84. The first valve port 81 is communicated with the exhaust pipe 22 of the compressor body 2, the third valve port 83 is communicated with the second return air pipe 25 of the compressor body 2, the second valve port 82 is communicated with the inlet of the outdoor heat exchanger 40, and the fourth valve port 84 is communicated with the outlet of the indoor heat exchanger 210.

[0087] Thus, the four-way valve 8 has two operating states: when the four-way valve 8 is de-energized, the HVAC equipment 1000 operates normally and enters the refrigeration cycle mode. At this time, the first valve port 81 can communicate with the second valve port 82, and the third valve port 83 communicates with the fourth valve port 84, and the refrigerant flows in the first direction in the circulation loop. After the refrigerant is discharged from the exhaust pipe 22 of the compressor body 2, it flows through the four-way valve 8 to 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 in sequence. 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 the cold air is output to the indoor by heat exchange between the low-temperature refrigerant and the indoor air. Then, the refrigerant flows back to the compressor body 2 through the suction port 12 and the suction pipe 23.

[0088] When the four-way valve 8 is energized, the HVAC equipment 1000 enters the defrosting cycle mode. At this time, the first valve port 81 can communicate with the fourth valve port 84, and the second valve port 82 communicates with the third valve port 83. 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 8 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, and 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, so as to output warm air to the indoor. The outdoor heat exchanger 40 is used as an evaporator. Then, the refrigerant flows back to the compressor body 2 through the suction port 12 and the suction pipe 23.

[0089] According to the HVAC equipment 1000 and the air conditioner outdoor unit 100 provided by the embodiments of the present application, the compressor integration system 10 as described above is adopted, and through the secondary vibration damping measures of the first vibration damping component 3 and the second vibration damping component 30, the vibration and noise received by the air conditioner outdoor unit 100 are effectively reduced, and the user experience is improved.
