[0006] To solve the above problems, the present disclosure provides a pipeline structure of a compressor, which includes:

[0007] An exhaust pipe, the exhaust pipe is connected to the exhaust port of the compressor, and the exhaust pipe includes a first pipe section and a second pipe section.

[0024] As Figure 1-2 shown, the present disclosure provides a pipeline structure of a compressor, which includes:

[0025] An exhaust pipe 1, the exhaust pipe is connected to an exhaust port 41 of the compressor 4, and the exhaust pipe includes a first pipe segment A and a second pipe segment B. One end of the first pipe segment A is connected to the exhaust port 41, and the other end is connected to the second pipe segment B. The second pipe segment B is a U-shaped pipe, the first pipe segment A is a straight pipe, and the center axis of the bottom segment of the U-shaped pipe (here, the bottom segment refers to Figure 2 the rightmost bent pipe segment of the U-shaped pipe in the lower left figure) has an included angle α with the projection of the center axis of the first pipe segment A on a horizontal plane (here, the horizontal plane refers to Figure 1 the front direction of the observer in the top view of). The value range of α is [100° - 150°]. By improving the exhaust pipe between the exhaust port of the compressor and the condenser, the present disclosure sets between the first straight pipe segment connected to the exhaust port of the compressor and the U-shaped pipe segment connected to the first straight pipe segment as follows: the center axis of the bottom segment of the U-shaped pipe has an included angle α with the projection of the center axis of the first pipe segment on the horizontal plane, and the value range of α is [100° - 150°], which can effectively reduce the strain of the pipeline, thereby reducing the stress value of the pipeline, effectively preventing the pipeline from breaking due to excessive stress value, and effectively improving the operation reliability and safety of the compressor and the air-conditioning system.

[0026] In order to reduce the vibration influence of the compressor on the suction pipe and the exhaust pipe, the upper exhaust pipe of the present disclosure connects the compressor and the shell-and-tube condenser respectively. The exhaust pipe connected to the exhaust port of the compressor adopts a U-shaped bend with an opening upward, and an obtuse angle is maintained between the U-bend and the straight pipeline to increase the flexibility of the pipeline.

[0027] In some embodiments, α is 120°. When the present disclosure further sets the included angle α between the projection of the center axis of the bottom segment of the U-shaped pipe on the horizontal plane and the projection of the center axis of the first pipe segment on the horizontal plane to be α = 120°, the strain value can be reduced to the maximum, further reducing the stress value of the pipeline, effectively preventing the pipeline from breaking due to excessive stress value, and effectively improving the operation reliability and safety of the compressor and the air-conditioning system.

[0028] The specific implementation of the exhaust pipe is as follows:

[0029] The exhaust pipe is connected to the compressor and the shell-and-tube condenser respectively. The exhaust pipe is divided into three sections as Figure 2 shown:

[0030] Section A is a straight section connected to the compressor. Section B is a U-shaped shock-absorbing bend. Section B and Section A need to form a certain angle to reduce pipeline strain. The angle α needs to satisfy 100° ≤ α ≤ 150°. The C end is connected to the shell-and-tube condenser.

[0031] Verified by test data, from the test data of the unit's exhaust pipe under nominal high-voltage refrigeration and maximum-load refrigeration high voltage, when starting up, when α is 90°, the stress on the pipeline is relatively large. Under the condition of maximum refrigeration high voltage, after three start-up tests, the strain value of the exhaust pipe exceeds 700μ, exceeding the specified 650μ at start-up. Under the condition of nominal high-voltage refrigeration, the strain value of the exhaust pipeline also exceeds 700u. When α is 120°, the measured data meets the test regulations, significantly reducing the stress on the pipeline. Therefore, the reliability of the pipeline can be effectively increased. The test conditions of nominal high-voltage refrigeration and maximum refrigeration high voltage are shown in Table 1 below:

[0032] Table 1

[0033]

[0034] Note: a The water flow rate determined under the nominal refrigeration test conditions is adopted.

[0035] In some embodiments, the connection between the first pipe section A and the U-shaped pipe is a bent connection, and the bending angle is 80° - 120°; and / or, the first pipe section A and the U-shaped pipe are connected through a bent pipe section D. This is the preferred connection method between the first straight pipe section and the U-shaped pipe in the present disclosure. That is, connecting in a bent manner can further effectively reduce the stress and strain of the pipeline, reduce vibration, and the effect of reducing stress and strain is better when the bending angle is 80° - 120°; connecting the first straight pipe section and the U-shaped pipe through the bent pipe section D can play a role of buffering connection, further reducing the stress and strain values.

[0036] In some embodiments, the bending angle is 90°. Setting the bending angle to 90° can minimize vibration and reduce stress and strain values to the greatest extent.

[0037] In some embodiments, the exhaust pipe 1 further includes a third pipe section C. One end of the third pipe section C is connected to the second pipe section B, so that the second pipe section B is connected between the first pipe section A and the third pipe section C. The present disclosure also enables the compressor exhaust to be discharged to the condenser for heat release by setting the third pipe section, which can connect it to the U-shaped pipe and the other end to the condenser.

[0038] In some embodiments, the third pipe section C is an "L"-shaped pipe section. This is the preferred structural form of the third pipe section in the present disclosure. By setting it as an "L"-shaped pipe section, it can further form a bending effect, further play a role in buffering gas, and the vibration reduction effect is better.

[0039] In some embodiments, the connection between the third pipe section C and the U-shaped pipe is a bent connection, and the bending angle is 80°-120°. This is the preferred connection method between the third pipe section and the U-shaped pipe of the present disclosure. That is, connecting in a bent manner can further effectively reduce the stress and strain of the pipeline, reduce vibration, and the effect of reducing stress and strain is better when the bending angle is 80°-120°.

[0040] In some embodiments, the pipeline structure further includes a compressor suction pipe 2. One end of the compressor suction pipe 2 is connected to the suction port 42 of the compressor 4, and the other end is connected to the gas-liquid separator 5. The structure of the compressor suction pipe can play a role in introducing the gas separated by the gas-liquid separator into the compressor suction port for suction and compression.

[0041] In some embodiments, the compressor suction pipe 2 includes at least two U-shaped bent pipe sections;

[0042] At least two of the U-shaped bent pipe sections are connected in sequence. By setting the compressor suction pipe as at least two U-shaped bent pipe sections, it can further buffer the gas, reduce the pipeline vibration, and increase the flexibility of the pipeline.

[0043] Both ends of the compressor suction pipe are respectively connected to the gas-liquid separator and the compressor, and are connected by two consecutive U-shaped bend structures, increasing the pipeline flexibility and reducing the vibration hazard.

[0044] In some embodiments, the pipeline structure further includes a gas-liquid separator suction pipe 3. One end of the gas-liquid separator suction pipe 3 is connected to the evaporator, and the other end is connected to the gas-liquid separator 5. The structure of the gas-liquid separator suction pipe can play a role in introducing the gas separated by the evaporator into the gas-liquid separator to complete gas-liquid separation.

[0045] The present disclosure also provides an air conditioner, which includes the pipeline structure of the compressor described in any one of the preceding items, and further includes a condenser 6. The other end of the exhaust pipe 1 is connected to the condenser 6. The present disclosure improves the exhaust pipe between the compressor exhaust port and the condenser. The angle α is set between the central axis projection of the bottom section of the U-shaped pipe on the horizontal plane and the central axis projection of the first pipe section on the horizontal plane, and the value range of α is [100°-150°], which can effectively reduce the strain of the pipeline. When α = 120°, the strain value is reduced the most, thereby reducing the stress value of the pipeline, effectively preventing the pipeline from breaking due to excessive stress value, and effectively improving the operation reliability and safety of the compressor and the air conditioning system.

[0046] The above are only the preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure. The above is only the preferred implementation manner of the present disclosure. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present disclosure, several improvements and variations can still be made, and these improvements and variations should also be regarded as the protection scope of the present disclosure.
