摘要：
CO2 is a safe natrual refrigerant which had been and will be widely used in air condi-tioning and heat pump systems. The thernodynamic analysis of the CO2 transcritical cycleis presented in this paper. The result shows that the CO2 cycles offers heat recovery benefitas a heat pump system. It is possible that the COP value of CO2 cycle can compete withthose of R22 or R134a if two stage compression system or an expander system are used.
