Liquid separator and compressor

Abstract

The invention relates to a liquid separator and a compressor. The liquid separator comprises a cylinder body and an elastic pipe, wherein an expansion and contraction cavity is formed in the elastic pipe, and the expansion and contraction cavity communicates with the inner cavity of the cylinder body, so that when pressure in the cylinder body changes, the elastic pipe deforms elastically along with the pressure in the cylinder body, and the volume of the expansion and contraction cavity is adjusted. According to the liquid separator, the gas specific volume of the compressor is automaticallyadjusted through the elastic pipe, the flow of a refrigerant delivered by the compressor is kept stable, the pressure ratio of the compressor is guaranteed to be constant, and the volume efficiency ofthe compressor is maintained to be stable.

Description

technical field [0001] The invention belongs to the refrigeration field, in particular to a liquid separator and a compressor. Background technique [0002] In the low-pressure cavity rotary compressor, the refrigerant is directly discharged from the compressor through the pipeline after being compressed by the compressor pump body, and enters the condenser in the refrigeration or heating system. However, the following 2 often exist during the system test and compressor operation question: [0003] 1. The situation where the suction and exhaust pressure is unstable and the energy efficiency of the compressor is reduced: when the pressure difference in the liquid separator is large, the pressure drop on the suction side of the compressor will increase during the operation, so that the gas specific volume returned to the compressor Increase, resulting in a decrease in the refrigerant flow rate delivered by the compressor, resulting in a reduction in cooling capacity and effic...

Problems solved by technology

[0003] 1. The situation where the suction and exhaust pressure is unstable and the energy efficiency of the compressor is reduced: when the pressure difference in the liquid separator is large, the pressure drop on the suction side of the compressor will increase during the operation, so that the gas specific volume returned to the compressor increase, resulting in a decrease in the refrigerant flow rate delivered by the compressor, resulting in a reduction in cooling capacity and efficiency; excessive selection of the liquid separator will increase the cost of the compressor

[0004] 2. The design of the liquid separator bracket also leads to more obvious vibration of the liquid separator body and the whole machine, resulting in an increase in the overall vibration of the compressor, which is inconsistent with the original intention of reducing vibration in the design of the compressor
