Problems solved by technology

However, those skilled in the art are not aware of the key problem of reducing energy efficiency due to heat transfer due to the pump body itself, so that there is always a gap between the refrigerant gas and the pump body in the prior art. Large temperature difference, heat exchange between the refrigerant gas and the pump body, and the heat transfer rate is fast, resulting in the loss of energy efficiency, reducing the compression energy efficiency, thereby reducing the overall performance ratio of the compressor
[0005] In order to solve the above problems and improve the overall efficiency ratio of the compressor, the applicant once proposed: replace the upper bearing, the lower bearing and the cylinder assembly in the pump body with the upper bearing of the material with low thermal conductivity, and the lower bearing of the material with low thermal conductivity , the piston of low thermal conductivity material and the cylinder of low thermal conductivity material, or replace some components with low thermal conductivity material as a whole. Due to the high cost of low thermal conductivity material, the cost of the compressor is high

Description

technical field [0001] The present application relates to the technical field of compressors, in particular to a rotary compressor. Background technique [0002] Compressor is a fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. Low-temperature and low-pressure refrigerant gas is sucked through the intake pipe, and the pump body is driven by the drive assembly to compress the sucked refrigerant gas. Finally, the high-temperature and high-pressure refrigerant gas is discharged to the outlet pipe to provide power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression→condensation→expansion→evaporation. [0003] In the specific working process of the compressor, the refrigerant gas enters the pump body through the intake pipe, and the refrigerant gas is compressed by the pump body to form compressed refrigerant gas. At this time, the temperature of the compressed refrigerant gas drops and ...
