The paper gives results of a theoretical evaluation of the performance and efficiency of 11 non-chlorofluorocarbon (CFC) refrigerants. An analytical method using a limited set of property data is used as a tool. The performance of these refrigerants is determined for a variety of vapor-compression cycles which are thermodynamic analogies to existing systems. Through separation of the basic vapor-compression cycle into elemental cycles representing only throttling losses or only compression superheating losses, important information is drawn about the design implications of subcooling or superheating the refrigerant. It is shown through this analysis that alternative, as well as standard, refrigerants fall into two general performance classes. These classes result in important performance and efficiency information which can be used to develop a vapor-compression system design tailored to the refrigerant class.
