Abstract

The present invention discloses a refrigerant compressor and a method for reducing oil content in exhaust gas through the refrigerant compressor. The refrigerant compressor comprises a housing, a motor assembly, a pump assembly and a rotation shaft, wherein the motor assembly, the pump assembly and the rotation shaft are arranged in the housing , the clearance space between the motor assembly and the pump assembly and between the rotation shaft and the housing comprises a first space for storing a refrigerant discharged by the pump assembly and a second space for storing a refrigeration oil, and the ratio V1 / V of the volume V1 of the first space to the volume of the clearance space is more than or equal to 60%. According to the present invention, the refrigerant compressor adopts the structure to increase the flowing time of the refrigerant in the housing and increase probability of collision and combination of the refrigeration oil contained in the refrigerant discharged by the refrigerant compressor so as to reduce the oil content in the exhaust gas, and the measure for reducing the oil content in the exhaust gas basically does not change the internal structure of the refrigerant compressor, such that the refrigerant compressor cost basically can not be increased.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a refrigeration compressor and a method for reducing the oil content rate of the exhaust gas. Background technique [0002] With the development of refrigeration technology, people have higher and higher requirements for energy saving and noise of air conditioners and heat pump water heaters, and one of the most important influencing factors is the performance and noise of compressors. [0003] The compressors in the prior art generally have a pump body assembly, a motor assembly and a rotating shaft connecting the motor assembly and the pump body assembly, and the three are fixed inside a fully enclosed casing. A large number of tests have proved that the oil content of the compressor exhaust has a great influence on the performance of the air conditioner, so how to take measures to reduce the oil content of the compressor exhaust has become one of the compressor resear...
