【Abstract】 In this paper, the thermodynamic property equations for R22 and its alternatives are established by use of the new cubic of state equation. On this basis, the performance simulation analysis of the thermodynamic cycle of these refrigerants in marine unit air conditioning system with high temperature is made. The comprehensive analysis and comparison of the alternative refrigerants concerning environmental protection, economics and security are also made.更多还原
