Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a liquid distributor, a compressor and an air conditioning system. Background Art

[0002] The liquid separator is also called a gas-liquid separator. It is installed at the inlet of the compressor for gas-liquid separation. The liquid separator can separate the gas-liquid mixture from the evaporator. The separated gas refrigerant enters the compressor through the suction pipe in the liquid separator cylinder. The separated liquid is stored at the bottom of the liquid separator, thereby preventing the liquid refrigerant from directly entering the compressor and preventing the compressor from having liquid hammer problems. The separated liquid refrigeration oil enters the compressor pump structure through the small hole at the lower end of the liquid separator suction pipe for lubrication.
