[0031] In the embodiment, the compressor assembly forms multiple bends through the first exhaust pipe section 210, the second exhaust pipe section 250 and the third exhaust pipe section 280, the bends can effectively improve the modal stress of the pipeline, the bend structure formed by the back-shaped or U-shaped structure of the pipeline can effectively reduce the overall stiffness of the pipeline, forms a spring-like elastic structure, and thus has a buffering and weakening effect on the impact force.

[0032] For the rotor compressor, there mainly exist horizontal torsional shear caused by rotor rotation and tensile or compression caused by vertical vibration; according to the mechanical characteristics, the farther the straight connection pipeline is from the rotation center, the greater the deformation is, thus for the pipeline design, the spatial span of the pipeline can effectively reduce the horizontal torsional shear. In the embodiment, the pipeline design is utilized to form the U-shaped span section of the exhaust pipeline which spans the top of the compressor body 100, so that the distance between the exhaust pipeline and the rotation center can be shortened by the U-shaped span section, and the shear stress caused by the compressor rotation can be effectively reduced.

[0033] In one embodiment, the second exhaust pipe section 250 further comprises a second U-shaped section, the opening of the second U-shaped section faces the top of the compressor body 100, the first end of the second U-shaped section is connected with the first exhaust pipe section 210, and the second end is connected with the U-shaped span section.

[0034] In the embodiment, the second U-shaped section of the second exhaust pipe section 250 can change the extension direction of the exhaust pipeline 200, so that the pipeline extending downward along the U-shaped span section extends toward the top of the compressor body 100 under the bending action of the second U-shaped section of the second exhaust pipe section 250, thereby facilitating the connection with the first exhaust pipe section 210, realizing multiple bending of the pipeline, improving the flexibility of the exhaust pipeline 200, and improving the absorption of the vibration energy of the compressor by the exhaust pipeline 200.

[0035] In one embodiment, the first exhaust pipe section 210 comprises a first U-shaped section, the opening of the first U-shaped section faces the bottom of the compressor body 100, the first end of the first U-shaped section is connected with the exhaust port, and the second end is connected with the first end of the second U-shaped section.

[0036] In the embodiment, the first exhaust pipe section 210 comprises a first U-shaped section, since the first exhaust pipe section 210 is connected with the exhaust port of the compressor body 100, the exhaust port of the compressor body 100 faces upward, the first U-shaped section can change the direction of the pipeline on the basis of realizing the connection with the exhaust port, so that the first exhaust pipe section 210 is more easily connected with the second exhaust pipe section 250, and a pipe section extending along the axial direction of the compressor body 100 can be formed, so that the exhaust pipeline has sufficient length to meet the design requirements.

[0037] In one embodiment, the U-shaped span section comprises an inclined section which gradually inclines toward the top of the compressor body 100 along the direction close to the bottom of the U-shaped span section.

[0038] In the embodiment, the inclined section is located between the vertical section and the bottom of the U-shaped spanning section, so that the vertical section is connected to the bottom of the U-shaped spanning section through the inclined section, the span of the bottom of the U-shaped spanning section is reduced, the flow of the refrigerant from the vertical section to the bottom of the U-shaped spanning section is smoother, the flow resistance is reduced, the impact generated during the flow of the refrigerant from the vertical section to the bottom of the U-shaped spanning section is reduced, the flow pressure loss of the refrigerant is reduced, and the flow kinetic energy of the refrigerant is ensured.

[0039] In addition, the inclined section is used to realize the flow conversion of the vertical section to the bottom of the U-shaped spanning section, the number of bends of the exhaust pipeline 200 is increased, and the pipeline operation stress is reduced.

[0040] In one embodiment, the third exhaust pipe section 280 further comprises a third U-shaped section, the opening of the third U-shaped section faces the top of the compressor body 100, and the first end of the third U-shaped section is connected to the second end of the U-shaped spanning section.

[0041] In the embodiment, by arranging the third U-shaped section, on the one hand, the flow direction of the refrigerant in the exhaust pipeline 200 can be changed again, and the design requirements of the exhaust pipeline 200 are met, and on the other hand, the number of bends can be further increased, the flexibility of the exhaust pipeline 200 is improved, and the absorption of the vibration energy of the compressor by the exhaust pipeline 200 is improved.

[0042] In one embodiment, the first exhaust pipe section 210 is located in the first plane, the second U-shaped section of the second exhaust pipe section 250 is located in the second plane, the U-shaped spanning section of the second exhaust pipe section 250 is located in the third plane, and the third exhaust pipe section 280 is located in the fourth plane, the included angle between the first plane and the second plane is a, a≥60°, the included angle between the second plane and the third plane is b, a+b≥180°, and the included angle between the third plane and the fourth plane is c≥90°.

[0043] In the embodiment, the first exhaust pipe section 210 is located in the first plane, which means that the center axis of the entire first exhaust pipe section 210 is located in the first plane, the second U-shaped section of the second exhaust pipe section 250 is located in the second plane, the U-shaped spanning section of the second exhaust pipe section 250 is located in the third plane, which means that the center axis of the second U-shaped section of the second exhaust pipe section 250 is located in the second plane, and the center axis of the U-shaped spanning section is located in the third plane, and the third exhaust pipe section 280 is located in the fourth plane, which means that the center axis of the third exhaust pipe section 280 is located in the fourth plane.

[0044] The first exhaust pipe section 210, the second U-shaped section, the U-shaped crossing section, and the third exhaust pipe section 280 are located in different planes. The bending direction of different pipe sections can be adjusted by changing the planes they are in, so that the structural design of each pipe section of the exhaust pipe 200 is more in line with the structural design of the compressor body 100. At the same time, it can also form a good deflection design between each pipe section of the exhaust pipe 200, which meets the design requirements of the exhaust pipe 200.

[0045] In one embodiment, the first plane and the second plane are perpendicular to each other, the third plane is perpendicular to the second plane and parallel to the first plane, the fourth plane is perpendicular to the third plane and parallel to the second plane, and the fourth plane and the second plane are located on different sides of the third plane, which can make the pipeline layout of the exhaust pipe 200 more reasonable.

[0046] In one embodiment, the compressor assembly further includes a pipe fastener, a high-pressure switch 240, and a high-pressure sensor 270, which are connected to the exhaust pipe 200. The pipe fastener is installed on the exhaust pipe 200 and secures the high-pressure switch 240 and the high-pressure sensor 270.

[0047] In this embodiment, pipe fixing blocks 230 and 260 are installed on the exhaust pipe 200.

The high-pressure switch 240 is mounted on pipe fixing block 230, which constrains and fixes the high-pressure switch 240, preventing root breakage due to vibration and improving its safety. The high-pressure sensor 270 has a heavy head and a long extension, making it prone to swaying and excessive shear stress, potentially leading to breakage. Mounting the high-pressure sensor 270 on pipe fixing block 260 constrains it, reducing its distance from the cantilever and effectively minimizing its sway, thus providing effective protection.

[0048] By setting up a high-pressure switch 240 and a high-pressure sensor 270, the internal pressure of the exhaust pipe 200 can be monitored in real time, providing dual protection for the safe operation of the system.

[0049] In one embodiment, a temperature-sensing sleeve 220 is also provided on the exhaust pipe 200. The temperature-sensing sleeve 220 is located in the horizontal section of the first exhaust pipe section 210 and can detect the exhaust temperature of the compressor, thereby monitoring the operating status of the compressor.

[0050] In one embodiment, the first exhaust pipe section 210, the second exhaust pipe section 250 and the third exhaust pipe section 280 are in a segmented structure, and the three sections are connected in sequence to form the exhaust pipe 200, wherein the pipe diameter of the first exhaust pipe section 210 is smaller than that of the second exhaust pipe section 250, so that the first exhaust pipe section 210 can be inserted into the second exhaust pipe section 250 to achieve connection between the first exhaust pipe section 210 and the second exhaust pipe section 250, the pipe diameter of the second exhaust pipe section 250 is the same as that of the third exhaust pipe section 280, and the second exhaust pipe section 250 and the third exhaust pipe section 280 can be fixedly connected through a connecting sleeve.

[0051] In one embodiment, the compressor assembly further comprises a gas-liquid separator 600 and a suction pipe 500, the gas-liquid separator 600 is connected to the compressor body 100, and the bottom of the U-shaped span section spans over the gap between the compressor body 100 and the gas-liquid separator 600, which can reduce the influence of the position of the exhaust pipe 200 caused by the compressor body 100, and further reduce the shear stress caused by the rotation of the compressor.

[0052] In one embodiment, the suction pipe 500 is connected to the top of the gas-liquid separator 600 and forms a back-shaped bending structure.

[0053] In the present embodiment, the back-shaped bending structure refers to the overall trend of the suction pipe 500 in a back-shaped structure, mainly for the bending trajectory of the bending structure, and does not limit different bending positions of the back-shaped bending structure to be located in the same plane.

[0054] In the present embodiment, by designing the suction pipe 500 as a back-shaped bending structure, the special form of the back-shaped bending structure can be used to achieve a damping effect, and the vibration effect of the suction pipe 500 during operation can be reduced.

[0056] In the present embodiment, by bending the suction pipe 500 multiple times, the flexibility of the suction pipe 500 can be improved by multiple bending of the suction pipe 500, the absorption capacity of the suction pipe 500 to pipe vibration can be improved, the influence of pipe vibration can be reduced, and the suction pipe 500 passes below the gas-liquid separator 600, so that the pipe arrangement of the suction pipe 500 can pass through a position with less influence, effectively reducing the shear force caused by the rotation of the compressor.

[0057] In one embodiment, the suction pipeline 500 further comprises a second suction pipeline section 530, which is connected to the fifth U-shaped section and is bent relative to the fifth U-shaped section in a first direction in a cross section perpendicular to the central axis of the compressor, wherein the first direction is a direction away from the connection position of the compressor body 100 and the gas-liquid separator 600. Since the first direction is in the cross section perpendicular to the central axis of the compressor, the bending direction of the second suction pipeline section 530 relative to the fifth U-shaped section is also limited by the first direction, that is, the second suction pipeline section 530 is bent in the direction away from the middle region of the compressor body 100 and the gas-liquid separator 600 in the cross section, so that the second suction pipeline section 530 can be away from the connection position of the compressor body 100 and the gas-liquid separator 600, reducing the influence of the vibration of the compressor body 100 on the second suction pipeline section 530, and reducing the operating stress of the second suction pipeline section 530.

[0058] In the embodiment, the suction pipeline 500 comprises the first suction pipeline section 510 and the second suction pipeline section 530, and both the first suction pipeline section 510 and the second suction pipeline section 530 comprise a bent pipeline section, so that the number of bends of the suction pipeline 500 can be increased, the flexibility of the suction pipeline 500 is further improved, and the vibration absorption capacity of the suction pipeline 500 is improved.

[0060] Through the above structural design, the pipeline layout of the suction pipeline 500 can be further optimized, the vibration reduction performance of the suction pipeline 500 is improved, and the shear force caused by the rotation of the compressor is reduced.

[0061] In one embodiment, the first suction pipeline section 510 of the suction pipeline 500 is provided with a low-pressure switch 520 and a pipe fixing block 601, the pipe fixing block 601 is installed on the first suction pipeline section 510 and fixes the low-pressure switch 520.

[0062] In one embodiment, the first suction pipeline section 510 is made of a copper pipe.

[0063] For reference Figure 5 and Figure 6As shown, by the above pipeline space layout, the compressor assembly of the embodiment of the present application is simulated as a whole, 6-order modes of the pipeline are obtained in the operating range of 30-120 Hz, the operating stress of the pipeline is effectively improved and is far less than the standard 100 Mpa; at the same time, the transportation stress of the pipeline is simulated to be the maximum of 33.27 Mpa, which is less than the standard.

[0064] For better understanding Figure 4 As shown, according to the embodiment of the present application, the air conditioner comprises the compressor assembly as described above.

[0065] In the embodiment, the air conditioner comprises a compressor body 100, an exhaust pipeline 200, a condenser 300, an evaporator 400 and a suction pipeline 500. The compressor body 100 flows the high-temperature and high-pressure gas into the condenser 300 through the exhaust pipeline 200 by high-speed rotation of the rotor; similarly, the compressor body 100 sucks the low-temperature and low-pressure gas discharged from the evaporator 400 into the gas-liquid separator 600 through the suction pipeline 500. Since the refrigerant needs to go through a cycle process of high-temperature and high-pressure gas, condenser, throttling device and evaporator, rotation of the rotor and flow of the high-pressure gas, vibration of the exhaust pipeline connected therewith is caused, so the pipeline layout of the cavity of the compressor body connected therewith is focused on. In order to ensure that the pipeline will not be cracked or broken due to excessive stress during transportation, and ensure long-term reliable operation of the air conditioner without leakage or rupture due to fatigue of the pipeline, the above compressor assembly is designed in the embodiment of the present application, the pipeline structure is optimized, appropriate deflection of the pipeline is achieved, the layout of the exhaust pipeline 200 through multiple bends and across the compressor body 100 significantly reduces the transportation and operating stress, and the layout of the suction pipeline 500 through the back-shaped bend structure and through the lower part of the gas-liquid separator 600 makes the transportation and operating stress be below the fatigue and rupture strength. The condenser 300 is located in the outdoor cavity and is located at the left side of the compressor body 100; the evaporator 400 is located in the indoor cavity and the connecting pipeline crosses the partition plate to connect the two devices.
