| Abstract: | Based on the analysis of the conventional vapor compressing refrigeration system, introduces the principle of ejector type decompression, and its application into re frigeration （heat pump） system. Puts forward the new compression/injection refrigeration circulation system. Makes thermodynamics analysis on the new improved refrigeration system. Combined with the characteristics of refrigerant R134a, concludes that the superi or performance of the new refrigeration system, improves the energy utilization efficiency of the refrigeration system which has certain directive significance to refrigeration and air conditioning system of energy research. |
