Abstract

The invention provides a rotary type compressor and a gas-liquid separator thereof. According to the invention, the gas-liquid separator comprises a liquid separator cylinder body, and an air suction pipe, an air exhaust pipe and a connecting pipe which are respectively and fixedly connected with the liquid separator cylinder body, wherein a first end of the connecting pipe is communicated with acavity of a lower flange which is connected with an air exhaust side of a low-pressure compressive structure of the rotary type compressor and penetrates in the liquid separator cylinder body, and a second end of the connecting pipe penetrates out the liquid separator cylinder body and is communicated with an air suction cavity of a high-pressure compressive structure of the rotary compressor. According to the invention, the rotary type compressor comprises the low-pressure compressive structure, the high-pressure compressive structure and the compressor cylinder body, and the rotary type compressor also comprises the gas-liquid separator, wherein the gas-liquid separator is installed on the outside of the compressor cylinder body. The gas compressed by the low-pressure compressive structure can be exhausted and flows in the high-pressure compressive structure by the connecting pipe, and the gas flowing through the connecting pipe can generate heat exchange with the gas-liquid separator when passing through the connecting pipe and meanwhile the temperature of the gas can be lowered, thus the performance and reliability of the compressor can be improved.

Description

technical field [0001] The invention relates to the field of air conditioning, and more specifically, to a rotary compressor and a gas-liquid separator thereof. Background technique [0002] The energy efficiency ratio of ordinary air-conditioning single-stage compressors drops significantly when heating at low temperatures, so auxiliary electric heating is needed to meet the heating capacity requirements of the system, which will increase power consumption. Most of the existing two-stage compressor refrigerants use CO 2 , and this kind of refrigerant generates a lot of pressure during work, which requires high strength of the compressor. The two-stage compression used for the existing R22 and R410A refrigerants can be divided into two-stage two-stage compression system and one-stage two-stage compressor system. The intercooling effect of the machine is very poor, resulting in a low energy efficiency rating. Contents of the invention [0003] The invention aims to provi...
