In this paper, cycle performance characteristics of a cascade refrigeration system with internal heatexchanger for cascade heat exchanger using alternative freon refrigerants is presented to offer the basicdesign data for the operating parameters of the system. This system considered in this study is consistedof a high temperature cycle using Freon refrigerant R23, R508B and low temperature cycle using Freonrefrigerants R22, R507A. The operating parameters of this system include subcooling and superheatingdegree, evaporating temperature, compressor efficiency, and so on. The main results were summarized asfollows : The COP of cascade refrigeration system using R23/R507A is the highest results in this study. The COP of cascade refrigeration system with internal heat exchanger only in high temperature cycle isthe highest value among three cycle, such as only low temperature cycle, only high temperature cycleand all the cycle.
