Abstract: As a typical own machinery, the compressor impeller efficiency and appropriate stator structure design has been paid close attention by the field. The focus on the fundamental goal is the flow losses, to reduce the energy consumption. The plethora of related research in recent years also can prove. The article simply analyses the propane refrigeration technology and process, and discusses in detail the propane refrigeration compressor of air chamber structure improvement design, numerical simulation, hope this can bring certain inspiration for professionals.

Key words: The propane refrigeration compressor, Air chamber, Structure improvement design
