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.

[0036] 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 them to be performed in the particular order described or illustrated, unless the order of performance is explicitly stated. It should also be understood that additional or alternative steps may be used.
[0037] 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 indicates otherwise, terms such as "first", "second", and other numerical terms do not imply an order or sequence when used herein. 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.
[0038] For ease of description, spatial relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure relative to another element or feature.

Thus, the exemplary term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are accordingly interpreted.
[0039] In the related art, in order to reduce the volume of the air conditioner outdoor unit, the compressor and the connecting pipelines are integrated in a housing, and the housing is used as a gas-liquid separator, which can shield part of the noise generated by the compressor body during operation. However, the exhaust noise of the compressor body is still relatively large, affecting the user experience.
[0040] For this reason, an embodiment of the present application provides a compressor integration system 10, which can effectively reduce the exhaust noise generated when the compressor body operates and improve the user experience.
[0041] Figure 1 It is a schematic structural diagram of a compressor integration system according to an embodiment of the present application. Figure 2 is Figure 1 a partial sectional view of the compressor integration system shown.
[0042] Referring to Figure 1 and Figure 2 An embodiment of the present application provides a compressor integration system 10, which includes a housing 1, a compressor body 2, and an exhaust pipe 3.
[0043] The housing 1 has opposite top end 13 and bottom end 14 along its own height direction. The top end 13 is provided with an exhaust port 11, and a muffler chamber 15 communicating with the exhaust port 11 is further provided outside the top end 13. An outlet pipe 16 is provided at one end of the muffler chamber 15 away from the exhaust port 11.
[0044] The compressor body 2 is disposed in the housing 1. The compressor body 2 includes a tank body 21 and an exhaust joint 22 communicating with the tank body 21. A compression component is further disposed in the tank body 21 for compressing the low-temperature and low-pressure gaseous refrigerant entering the tank body 21 into a high-temperature and high-pressure gaseous refrigerant.
[0045] One end of the exhaust pipe 3 is connected to the exhaust joint 22, and the other end extends from the exhaust port 11 to the muffler chamber 15.
[0046] In the related art, a low-pressure tank is generally used to store a refrigerant refrigerant with a certain volume, and the volume is about 2L to 4L. The gas-liquid separator is used to separate the gaseous refrigerant and the liquid refrigerant in the gaseous mixed refrigerant, and the volume is 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, and the volume is 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, and has a compact structure and small occupied space.
[0047] Further, the housing 1 has opposite top end 13 and bottom end 14 along its own height direction. The top end 13 is provided with an exhaust port 11, and a muffler chamber 15 communicating with the exhaust port 11 is further provided outside the top end 13. The muffler chamber 15 can be directly welded to the top end 13 of the housing 1. The compressor body 2 compresses gas to do work during operation, generating a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant generates a large exhaust noise when flowing through the exhaust pipe 3, and the high-temperature and high-pressure gaseous refrigerant enters the muffler chamber 15 through the exhaust pipe 3. Then the high-temperature and high-pressure gaseous refrigerant is discharged from the sound outlet pipe 16 provided on the muffler chamber 15 to other circulation pipelines and enters the subsequent refrigeration or heating cycle.
[0048] In this embodiment, the muffler chamber 15 changes the propagation path and energy distribution of sound waves through acoustic intervention, thereby achieving noise reduction. For example, the muffler chamber 15 can reflect, absorb and interfere with sound waves through structural design (such as sudden cross-section, multi-chamber) and material selection (such as sound-absorbing fiber, micro-perforated plate), thereby systematically reducing the noise level of compressor exhaust. In practical applications, it can be comprehensively optimized according to the noise spectrum, air flow velocity and environmental conditions.
[0049] According to the compressor integration system 10 provided by the embodiment of the present application, by providing a muffler chamber 15 communicating with the exhaust port 11 outside the top end 13 of the housing 1, and a sound outlet pipe 16 is further provided at the end of the muffler chamber 15 away from the exhaust port 11, the muffler chamber 15 can be used as an exhaust passage and can also muffler the exhaust noise generated by the exhaust pipe 3, effectively reducing the exhaust noise generated by the compressor body 2 during operation and improving the user experience.
[0050] In some embodiments, the muffler chamber 15 is a columnar body with a hollow interior, and the ratio of the diameter of the muffler chamber 15 to the diameter of the exhaust pipe 3 is 3 to 10.
[0051] In this embodiment, the cross-sectional area of the muffler chamber 15 is different from that of the exhaust pipe 3. After the gaseous refrigerant enters the muffler chamber 15 from the exhaust pipe 3, due to the sudden change in the cross-sectional area, the acoustic impedance mismatch of the exhaust occurs. According to the acoustic boundary conditions, most of the acoustic wave energy is reflected back to the original path, and only a small amount is transmitted into the muffler chamber 15, thereby greatly attenuating the exhaust noise. Since the essence of noise reduction by the sudden change in cross-section is to change the acoustic impedance through the geometric structure and suppress noise using the acoustic wave reflection and energy dissipation mechanisms, in addition to the diameter of the muffler chamber 15 requiring a sufficient expansion ratio, the muffler chamber 15 also needs to match an appropriate length. In actual design, optimization can be carried out through acoustic simulation or experimental verification (such as 1 / 3 octave sound pressure level test). Considering the installation space, the outer diameter of the muffler chamber 15 is smaller than the outer diameter of the housing 1. Optionally, the ratio of the diameter of the muffler chamber 15 to the diameter of the exhaust pipe 3 is 3 to 10, which can not only meet the noise reduction effect but also meet the installation requirements. Exemplarily, the inner diameter of the muffler chamber 15 is 100 mm, and the inner diameter of the exhaust pipe 3 is 15 mm.
[0052] In some embodiments, the inner wall of the muffler chamber 15 is provided with an acoustic absorption layer. The acoustic absorption layer can be any one of fiber acoustic materials, foam acoustic materials, and micro-perforated plates, which is determined according to the frequency band of the noise, thereby further reducing the exhaust noise. Among them, fiber acoustic materials include glass wool, rock wool, polyester fiber, etc., and foam acoustic materials include polyurethane foam, aluminum silicate wool, etc. The micro-perforated plate is to open tiny holes on a metal plate, the hole diameter ≤ 1 mm, and the thickness of the metal plate is 0.1 mm - 1 mm.
[0053] Figure 3 For Figure 1 the top view of the internal structure of the compressor integrated system shown.
[0054] In some embodiments, the positive projection of the sound outlet pipe 16 on the end face of the top end 13 does not overlap with the exhaust port 11.
[0055] As Figure 3 shown, the sound outlet pipe 16 serves as the outlet of the muffler chamber 15 and is also the exhaust pipe. The positive projection of the sound outlet pipe 16 on the end face of the top end 13 does not overlap with the exhaust port 11, which can make the gaseous refrigerant entering the muffler chamber 15 through the exhaust pipe 3 at the exhaust port 11 rotate by a certain angle for noise reduction and then be discharged from the sound outlet pipe 16, thereby improving the noise reduction effect of the muffler chamber 15.
[0056] Figure 4 is a schematic structural diagram of an exhaust pipe of a compressor integrated system according to another embodiment of the present applicationFigure 5 Structural schematic diagram of another exhaust pipe of the compressor integration system according to another embodiment of the present application.
[0057] In some embodiments, the exhaust joint 22 is arranged at the top of the tank body 21 facing the top end 13, and the exhaust pipe 3 is a straight pipe or a bent pipe.
[0058] In one example, as Figure 4 shown, the exhaust joint 22 is arranged at the top of the tank body 21 facing the top end 13, and the exhaust pipe 3 is a straight pipe. One end of it is connected to the exhaust joint 22, and the other end directly enters the silencing chamber 15 through the exhaust port 11, with a simple structure. In another example, as Figure 5 shown, the exhaust pipe 3 is a bent pipe. Compared with the straight pipe, the bent pipe can reduce the rigidity of the exhaust pipe 3, slow down the vibration impact on the exhaust pipe 3, and further reduce the system noise.
[0059] In some embodiments, the exhaust joint 22 is arranged at the top of the tank body 21 facing the top end 13, and the exhaust pipe 3 includes a plurality of pipe segments sequentially connected in the space between the outer wall of the tank body 21 and the inner wall of the housing 1. Adjacent two pipe segments are bent at a preset angle, one of the pipe segments is connected to the exhaust joint 22, and the other pipe segment extends out of the exhaust port 11 and enters the silencing chamber 15.
[0060] As Figure 5 shown, the exhaust pipe 3 is a bent pipe. Exemplarily, the exhaust pipe 3 has a first pipe segment 31, a second pipe segment 32, a third pipe segment 33, a fourth pipe segment 34, and a fifth pipe segment 35 connected in sequence. Adjacent two pipe segments are bent at 90°. The first pipe segment 31 extends a first length towards the outer wall of the tank body 21 after being led out from the exhaust joint 22. The second pipe segment 32 is bent 90° from the first pipe segment 31 and extends a second length towards the bottom end 14. The third pipe segment 33 is bent 90° from the second pipe segment 32 and extends a third length along the direction parallel to the bottom end 14. The fourth pipe segment 34 is bent 90° from the third pipe segment 33 and extends a fourth length towards the top end 13, and then is bent towards the direction of the exhaust joint 22 and extended a fifth length. The fifth pipe segment 35 is bent 90° from the fourth pipe segment 34 and finally extends out of the exhaust port 11. Thus, the exhaust pipe 3 has high flexibility in structure after multiple bends, and the vibration received by the first exhaust pipe 3 is dissipated through the movement between each pipe segment, reducing the vibration stress and improving the service life.
[0061] In some embodiments, the exhaust pipe 3 includes any one of a copper pipe, a rubber hose, and a stainless steel braided net pipe, or a combination of at least two of them. In one example, the entire exhaust pipe 3 is any one of a copper pipe, a rubber hose, and a stainless steel braided net pipe. When the exhaust pipe 3 is a rubber hose, since it is built into the housing 1, there is no need to consider the problem of refrigerant leakage. In another example, both ends of the exhaust pipe 3 are copper pipes for easy welding connection, and the rest of the exhaust pipe 3 is a stainless steel braided net pipe, which improves the flexibility of the exhaust pipe 3 and further reduces the vibration and noise during the exhaust process.
[0062] In some embodiments, the compressor integrated system 10 further includes a first return air pipe 4 and a second return air pipe 5. A return air port 12 is further provided at the top end 13 of the housing 1. The compressor body 2 further includes a return air joint 23 communicated with the tank body 21. One end of the first return air pipe 4 is connected to the return air joint 23, and the other end of the first return air pipe 4 extends towards the top end 13. One end of the second return air pipe 5 extends out from the return air port 12, and the other end of the second return air pipe 5 is located inside the housing 1 and is spaced from the end of the first return air pipe 4 away from the return air joint 23.
[0063] As Figure 2 shown, the low-temperature gas-liquid mixed refrigerant entering the housing 1 from the second return air pipe 23 of 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 gaseous refrigerant floats on one side of the top end 13 of the housing 1. The gaseous refrigerant is sucked into the compressor body 2 under the negative pressure of the first return air pipe 4 for compression work, generating high-temperature and high-pressure gaseous refrigerant. Since the first return air pipe 4 and the second return air pipe 5 are separately arranged and isolated from each other, the vibration transmitted from the compressor body 2 to the first return air pipe 4 gradually dissipates and attenuates in the housing 1 and will not be transmitted to the second return air pipe 5 connected to the housing 1, thereby greatly reducing the low-frequency vibration and noise and improving the user's listening experience.
[0064] In some embodiments, in the circumferential direction of the housing 1, the end of the second return air pipe 5 located inside the housing 1 is staggeredly arranged from the end of the first return air pipe 4 away from the return air joint 23.
[0065] As Figure 3As shown, both the housing 1 and the compressor body 2 are cylinders. The compressor body 2 can stand upright within the housing 1, or it can lie horizontally within the housing 1. In this embodiment, the case where the compressor body 2 stands upright within the housing 1 is taken as an example for description. The low-temperature gas-liquid mixed refrigerant entering the housing 1 from the second return air pipe 5 contains liquid refrigerant. One end of the first return air pipe 4 away from the return air joint 23 is the return air end. The end of the second return air pipe 5 located within the housing 1 is offset from and not directly opposite to the return air end of the first return air pipe 4, which can prevent the liquid refrigerant from entering the first return air pipe 4 from the return air end under the action of its own gravity, reducing the possibility of liquid hammer problems occurring in the compressor body 2.
[0066] Exemplarily, a first connection line is formed between the end of the second return air pipe 5 located within the housing 1 and the central axis of the housing 1, and a second connection line is formed between the return air end of the first return air pipe 4 and the central axis of the housing 1. The first connection line and the second connection line are set at a preset angle θ. The larger the preset angle θ, the larger the offset angle between the end of the second return air pipe 5 located within the housing 1 and the return air end of the first return air pipe 4. When the preset angle θ = 180°, the possibility of liquid hammer problems occurring in the compressor body 2 is the smallest.
[0067] In some embodiments, the return air joint 23 is provided on the side of the tank body 21 near the bottom end 14, and the port of the end of the first return air pipe 4 away from the return air joint 23 is lower than the top of the tank body 21 facing the top end 13 or flush with the top of the tank body 21.
[0068] In one example, as Figure 2 shown, the compressor body 2 stands upright within the housing 1. A return air joint 23 is provided on the side of the tank body 21 of the compressor body 2 near the bottom end 14 of the housing 1. The end of the first return air pipe 4 away from the return air joint 23 can directly extend a preset length towards the top end 13 side. In another example, as Figure 4 shown, the end of the first return air pipe 4 away from the return air joint 23 can first bend towards the bottom end 14 side of the housing 1, bend again after bypassing the bottom end 14, and extend a preset length towards the top end 13 side of the housing 1. The end of the first return air pipe 4 away from the return air joint 211 is the return air end. The return air end extends towards the top end 13 of the housing 1. The return air end is higher than the top of the tank body 21 facing the top end 13 or flush with the top end of the tank body 21, which can ensure that the return air end is located in the gaseous refrigerant separated from the gas-liquid mixed refrigerant, facilitating the suction of the gaseous refrigerant into the compressor body 2 through the negative pressure of the compressor body 2.
[0069] In some embodiments, a connector 24 is further provided on the side of the tank body 21, and the connector 24 is connected to the end of the first return air pipe 4 away from the return air joint 23.
[0070] On the side of the tank body 21 of the compressor body 2, a connecting piece 24 can be provided. One end of the connecting piece 24 is connected to the side of the tank body 21, and the other end of the connecting piece 24 surrounds the outer periphery of one end of the first return air pipe 4 away from the return air joint 23, further reducing the vibration of the first return air pipe 4 and reducing noise. The shape of the connecting piece 24 is not limited as long as it can fix a section of the first return air pipe 4. One end of the connecting piece 24 can be welded to the side of the tank body 21, and one end of the connecting piece 24 can also be connected to the side 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, a connector joint 17 is further provided at the top end 13 of the housing 1. A terminal block is provided at the top of the compressor body 2, and the terminal block is electrically connected to the connector joint 17 through an adapter wire. As Figure 1 shown, the compressor body 2 is disposed in the housing 1. Components such as the rotor in the compressor body 2 are driven to rotate by a motor. The power supply and control signals of the motor are realized through an electronic control unit outside the housing 1. One end of the connector joint 17 is electrically connected to the electronic control unit through a wire, and the other end of the connector joint 17 is electrically connected to the terminal block through an adapter wire. The terminal block is electrically connected to the motor. The material of the adapter wire needs to meet the characteristics of being oil-resistant, refrigerant-resistant, and high-temperature-resistant.

The second vibration damping assembly 30 is disposed between the chassis 20 and the housing 1 of the compressor integration system 10, which can further reduce the vibration and noise of the compressor integration system 10, and thus reduce the vibration and noise of the outdoor unit 100 of the air conditioner.

The air conditioner indoor unit 200 is used to deliver cold air or hot air indoors to achieve the effect of cooling or heating up.
[0076] As Figure 6 and Figure 7 shown, 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 3 of the compressor body 2, the third valve port 83 is communicated with the second return pipe 5 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.
[0077] Thus, the four-way valve 8 has two working states: when the four-way valve 8 is powered off, the heating and ventilation equipment 1000 operates normally and enters the refrigeration cycle mode. At this time, the first valve port 81 can be conducted with the second valve port 82, and the third valve port 83 is conducted 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 3 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 to exchange heat between the low-temperature refrigerant and the indoor air, so as to output cold air indoors. Then the refrigerant returns to the compressor body 2 through the second return pipe 5 and the first return pipe 4.
[0078] When the four-way valve 8 is powered on, the heating and ventilation equipment 1000 enters the defrosting cycle mode. At this time, the first valve port 81 can be conducted with the fourth valve port 84, and the second valve port 82 is conducted 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 3 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 3 of the compressor body 2 exchanges heat with the indoor heat exchanger 210, so as to output hot air indoors. The outdoor heat exchanger 40 is used as an evaporator. Then the refrigerant returns to the compressor body 2 through the second return pipe 5 and the first return pipe 4.
[0079] According to the HVAC equipment 1000 and the outdoor unit 100 of the air conditioner provided by the embodiments of the present application, by adopting the compressor integration system 10 of the embodiments of the present application, a silencing chamber 15 communicated with the exhaust port 11 is arranged outside the top end 13 of the housing 1, and a sound outlet pipe 16 is further arranged at one end of the silencing chamber 15 far away from the exhaust port 11, so that the silencing chamber 15 can be used as an exhaust passage and can also silence the exhaust noise generated by the exhaust pipe 3, effectively reducing the exhaust noise generated when the compressor body 2 works, further reducing the exhaust noise of the outdoor unit 100 of the air conditioner, and improving the user experience.
