Embodiment Construction

[0040] Aiming at the problem that the gas-liquid separator in the prior art cannot adjust and control the oil return volume and liquid return volume, the present invention provides a gas-liquid separator capable of adjusting the oil return volume.

[0041] like figure 1 As shown, the gas-liquid separator of the present invention includes a casing 2 , an air outlet pipe 6 and an oil return assembly 7 .

[0042] Wherein, the oil return assembly 7 includes an oil return valve 5 , the inlet end of the oil return valve 5 communicates with the inside of the housing 2 , and the outlet end of the oil return valve 5 communicates with the air outlet pipe 6 .

[0043] Because the gas-liquid separator of the present invention is provided with an oil return assembly, one end of the oil return valve in the oil return assembly communicates with the inside of the housing 2, and the other end communicates with the air outlet pipe 6. Therefore, when there is a high-speed flow in the air outlet ...

Abstract

The invention discloses a gas-liquid separator. The gas-liquid separator comprises a casing, an air outlet pipe and an oil return assembly. The oil return assembly comprises an oil return valve. The inlet end of the oil return valve communicates with the interior of the casing. The outlet end of the oil return valve communicates with the air outlet pipe. By the adoption of the gas-liquid separator, oil liquid at the bottom of the gas-liquid separator can be pumped into the air outlet pipe and then returns back to a compressor, and the amount of returned oil can be controlled by controlling the action of the oil return valve in the oil return assembly, so that the amount of the returned oil can be adjusted. On the one hand, effective oil return can be achieved in a system, and on the other hand, compressor liquid impact caused by excessive liquid refrigerant absorption in the oil return process can be avoided, so that the reliability of the system can be improved. The invention further discloses the air conditioner system and a control method of the air conditioner system.

Description

technical field [0001] The invention relates to a gas-liquid separator. The present invention also relates to an air-conditioning system with the gas-liquid separator and a control method for the air-conditioning system. Background technique [0002] The gas-liquid separator is an important part in a refrigeration system (such as an air-conditioning system). On the one hand, its function is to separate a small amount of incompletely evaporated refrigerant returned from the evaporator of the system, so as to ensure that the compressor does not suck in liquid refrigerant and cause liquid Shock phenomenon, so as to avoid the damage of the compressor due to liquid shock; on the other hand, the function is to make a small amount of lubricating oil at the bottom of the gas-liquid separator return to the compressor, so as to avoid the lack of oil in the compressor and cause wear. [0003] In order to realize the return of lubricating oil, most of the gas-liquid separators in the p...
