Description

Technical Field

[0002] At present, in large-scale commercial or industrial fields, there are many places that choose centrifuges for refrigeration. When the centrifugal unit is operating under refrigeration conditions, the internal temperature of some centrifugal units or related components on the compressor is much lower than the external temperature. This will cause condensation on the outer surface of some external components, especially on the shell at the compressor suction port, which is basically close to the evaporation temperature. At this time, condensation will appear on the outer surface of the shell and related components nearby. The parts in this area will be covered with condensation water. Generally speaking, condensation will not affect the reliability of the compressor.

[0003] However, for electrical components, when condensation is severe, it may have a certain impact on the performance of the electric actuator, and in severe cases, it may even cause the electric actuator to fail, resulting in the inability to open and close the guide vanes at the compressor inlet. For centrifugal compressors, the installation position of the electric actuator used on the centrifuge is generally close to the air intake, where the temperature is very low, and there will be condensation on the electric actuator, especially when the unit is operating under low-temperature refrigeration or even ice storage conditions with lower evaporation temperatures, the condensation phenomenon will be more serious. When the electric actuator works for a long time in an environment with a large amount of condensation water, there is a risk of failure due to the long-term contact of the electrical components with water, which affects the reliability of the centrifuge operation.

[0004] Therefore, how to provide a compressor and an air conditioner having the same that can prevent condensation from occurring on the electric actuator and ensure the reliability of the centrifuge operation has become an urgent problem that technicians in this field need to solve.

[0030] See also Figure 1-2 As shown, the present application also discloses some embodiments, the compressor further comprises a balance pipe 4; the first end of the balance pipe 4 is connected to the oil tank 1, and the second end is connected to the compressor suction port.

[0031] Furthermore, the compressor also includes a gas-liquid separator, and the inlet of the gas-liquid separator is connected to the oil tank 1.

[0032] Further, the first exhaust port of the gas-liquid separator is connected to the inlet end of the anti-condensation channel 2;

[0033] And / or, the second exhaust port of the gas-liquid separator is connected to the first end of the balance pipe 4, which can prevent liquid lubricating oil from entering the balance pipe 4 or the anti-condensation channel 2, and then entering the compressor suction port, affecting the compressor performance.

[0034] Furthermore, the inlet end of the anti-condensation channel 2 is communicated with the balance pipe 4 .

[0035] Furthermore, the compressor further comprises a drainage pipe 5 , and the anti-condensation passage 2 is connected to the first exhaust port of the gas-liquid separator through the drainage pipe 5 .

[0036] Furthermore, at least one drainage pipe 5 is provided, and the inlet end of each drainage pipe 5 is connected to the first exhaust port of the gas-liquid separator; the outlet end of each drainage pipe 5 is connected to the anti-condensation channel 2. When there are multiple drainage pipes 5, heat is introduced in multiple ways to the vicinity of the electric actuator installed inside the shell, so as to more evenly and effectively increase the temperature of this area, ensure that the surface of the electric actuator has a certain temperature, avoid condensation, and thereby improve the reliability of the operation of the centrifugal compressor.

[0037] Furthermore, the anti-condensation element 3 is installed in the suction cavity of the compressor, and the anti-condensation channel 2 is arranged in the suction cavity of the compressor.

[0038] Furthermore, the anti-condensation channel 2 is arranged outside the anti-condensation element 3 and extends circumferentially around the outer periphery of the anti-condensation element 3, which can more effectively and comprehensively increase the temperature around the electric actuator and prevent condensation from occurring on the electric actuator.

[0039] Furthermore, a first curved section is provided on the anti-condensation channel 2, and the inlet end of the anti-condensation channel 2 is provided on the first curved section;

[0040] And / or, a second curved section is provided on the anti-condensation channel 2, and the outlet end of the anti-condensation channel 2 is provided on the second curved section.

[0041] Furthermore, the distance between the central axis of the first curved section and the center of the element to be protected from condensation 3 is a, where a is a constant;

[0042] And / or, the distance between the central axis of the second curved section and the center of the anti-condensation element 3 is b, where b is a constant. This allows the high-temperature refrigerant to circulate in the anti-condensation channel 2 for a longer time, and the anti-condensation channel 2 to stay longer at the inlet and outlet, which is more conducive to increasing the temperature around the electric actuator.

[0043] Furthermore, the outlet end of the anti-condensation channel 2 is connected to the compressor suction chamber, and the refrigerant can be recycled into the compressor. When the centrifuge is operated under refrigeration conditions, the temperature at the suction port of the centrifugal compressor is close to the temperature of the low-temperature refrigerant in the evaporator. The low-temperature refrigerant is sucked into the compressor housing by the compressor from the suction port, and is compressed by the centrifugal impeller in the centrifugal compressor. The compressor housing of the centrifuge is mainly used to install shaft system parts such as bearings, and the compressor motor is used to drive the centrifugal compressor impeller to rotate and do work. When the centrifuge is running, the oil tank 1 will contain a small amount of refrigerant. The high-temperature gas-liquid mixture after the refrigerant and the lubricating oil are mixed will evaporate through the gas-liquid separator. The gas-liquid separator will separate the gaseous refrigerant and the liquid lubricating oil. The liquid lubricating oil returns to the oil tank 1, and the gaseous refrigerant is transmitted to the housing through the balance pipe 4 and the drainage pipe 5, and enters the suction port of the compressor for compression. In this application, the heat in the oil tank balance pipe 4 is introduced into the anti-condensation channel 2 in the compressor housing through the drainage pipe 5. When the heat flows in the anti-condensation channel 2, the temperature near the electric actuator 3 installed on the electric actuator bracket is increased to prevent condensation on the surface of the electric actuator 3. After the heat flows through the heating flow channel inside the housing, it enters the air intake of the compressor, thereby preventing the condensation problem of the centrifuge electric actuator and ensuring the reliability of the centrifuge operation.
