| Abstract: | The thermophysical features of refrigerant R404A and R407A are compared respectively,and the feasibility of using R407A in freezing scroll compressor is investiga- ted. The scroll compressors using R404A and R407A were tested and the volumetric effi ciency,isentropic efficiency,discharge temperature and operating current are compared ac cordingly,which will provide reference for the development of the freezing scroll compres sors using R407A. |
