Current situation and development trend of screw refrigeration compressor in China

Screw compressor entered domestic market 30 years ago, and substituted other style compressors gradually and is becoming the superior selection in refrigeration and air-conditioning system of medium and high capacity with its market share increasing year by year. The technology improvement of the screw refrigeration compressor industry in China is elaborated from the aspects such as tion technology and capacity control and so on. rotor profile line, rotor processing, injec. The application of screw compressor into heat pump and freeze and cold storage is also briefly introduced. However, there are still some deficiencies requiring more efforts to be overcome in manufacture and control system for domestic screw compressor. The development trend of screw compressor is cautiously predicted. The study is hoped to provide some actual guidance for independent research and innovation.
