Abstract

The invention belongs to the field of compressor accessories, and discloses a liquid storage tank applied to a compressor. The liquid storage tank comprises a shell provided with an air inlet pipe andan air outlet pipe, and the air outlet pipe comprises an extending-in section which extends into the shell. The liquid storage tank further comprises a separator for separating out a liquid refrigerant, and a sleeve, wherein the separator is arranged between the air inlet pipe and the extending-in section, the sleeve sleeves the extending-in section, the end, away from the separator, of the sleeve is sealed, and the end, close to the separator, of the sleeve is used for receiving the liquid refrigerant which is obtained after separation by the separator. A first liquid storage space is formedbetween the sleeve and the extending-in section, and an oil return hole is formed in the pipe wall of the extending-in section and communicates with the first liquid storage space. According to the liquid storage tank applied to the compressor, flowing power of a liquid refrigerant and lubricating oil mixture can be guaranteed under the high-temperature condition with few refrigerants and the low-temperature condition with many refrigerants, the oil return amount is stable, and the requirement of a wide-environment-temperature operation heat pump system is met.

Description

technical field [0001] The invention relates to the technical field of compressor accessories, in particular to a liquid storage tank applied to a compressor. Background technique [0002] Under low temperature conditions, conventional air conditioning systems are prone to the phenomenon of compressor suction with liquid due to insufficient evaporation heat transfer, and even liquid shock in severe cases. Usually, a liquid storage tank is added at the suction end of the compressor to separate the gas-liquid refrigerant. The gas refrigerant enters the compressor from the liquid storage tank through the outlet pipe, and the liquid refrigerant and lubricating oil accumulate at the bottom of the liquid storage tank. A liquid return hole is provided on the side wall of the air outlet pipe of the liquid storage tank, and a small amount of mixture of liquid refrigerant and lubricating oil can enter the air outlet pipe through the liquid return hole, and then enter the compressor. ...
