Rotation compressor

Abstract

The invention discloses a rotation compressor. The rotation compressor comprises a shell, a compression mechanism, a motor assembly and an oil separation assembly. The shell is provided with an exhaust port. The compression mechanism is arranged in the shell and provided with a compression cavity. The motor assembly is arranged in the shell and comprises a rotor and a stator. The motor assembly is located between the compression mechanism and the exhaust port, and an exhaust channel is defined jointly by the motor assembly and the compression mechanism. One end of the exhaust channel is communicated with the compression cavity, and the other end of the exhaust channel is communicated with the exhaust port. The oil separation assembly is arranged in the exhaust channel and provided with a fluid collision face suitable for being impacted by fluid in the exhaust channel. According to the rotation compressor, the possibility that refrigerating machine oil in the rotation compressor enters a heat exchanger can be reduced, the heat exchange capability of the heat exchanger is guaranteed, and the heat exchange efficiency is improved. Meanwhile, the phenomenon that abrasion is increased due to the fact that the interior of the rotation compressor is lack of refrigerating machine oil can be prevented, and therefore the performance of the compressor is guaranteed, and reliability of working of the compressor is improved.

Description

technical field [0001] The invention relates to the field of air conditioner rotary compressors, in particular to a rotary compressor. Background technique [0002] During the working process of the air-conditioning rotary compressor, the refrigeration oil can play the role of cooling, sealing and lubricating inside the compressor. During the cycle operation of the refrigeration system, the refrigerating machine oil will usually be discharged from the compressor along with the circulating refrigerant of the compressor, and flow to the condenser or even the evaporator. The refrigerating machine oil will remain on the inner wall of the tube of the system heat exchanger, forming a thick oil film. However, due to the small thermal conductivity of the oil film, the heat exchange performance of the refrigerant side in the tube and the air side outside the tube of the heat exchanger is reduced, which affects the cooling or heating capacity of the air conditioner. At the same time,...

Problems solved by technology

However, due to the small thermal conductivity of the oil film, the heat exchange performance of the refrigerant side in the tube and the air side outside the tube of the heat exchanger is reduced, which affects the cooling or heating capacity of the air conditioner.

At the same time, the internal parts of the compressor will also increase wear due to lack of refrigeration oil lubrication, which will affect the performance of the compressor and even cause reliability problems in the compressor
