ABSTACT:In this paper, a review is made on the effect of refrigerants on the performance of refrigerating machines.The thermodynamic, thermophysical, chemical, economic characteristics of the refrigerants and their effect on the environment especially, on the ozone layer are analysed.Various operating conditions of vapor-compression refrigerating machines (from home refrigerators to large refrigeration stations of chemical enterprises) determine a variety of refrigeration cycles and refrigerants used in them.The goal of this work is to be able to make a choice out of the many refrigerants available, appropriate machines for best application and a guide to designers for new and better machine designs.The most optimal option can be selected on the basis of thermodynamic analysis of the refrigeration cycle.
