Fang Wang, Xian Ping Zhang, Feng Kun Wang, Xiao Wei Fan, Zhiwei Lian

Abstract

This paper deals with a thermodynamic analysis of a vapor compression refrigeration system with the new refrigerant R125/R600a blends, parameters and factors affecting the performance are investigated, and also a comparison with that of R22 is presented. Encouraging results are obtained, at a certain concentration of R125 in mixtures, the R125/R600a refrigerant blends perform better than R22 but with loss of volumetric cooling capacity in air conditioning applications. Which may provide useful information for alternative refrigerants.
