Multi-stage vapor compression refrigeration cycles are used in low temperature applications, as well as in refrigeration applications where temperature difference is high. In recent years, as environmental factors have gained more importance, the use of alternative refrigerants has been investigated. Although the way to research and achieve energy savings in refrigeration cycles seems to be minimizing compressor work, it is more attractive to work on optimizing the Coefficient of Performance (COP) as it gives the minimum power required for unit cooling. In this study, the performances of different refrigerants when used in an ideal two-stage vapor compression refrigeration cycle are analyzed parametrically and compared. Separate COP values of the system were calculated for each refrigerant by changing the evaporation and condensation temperatures. In addition, the compressor work and the changes of the cooling loads of the system are also presented. The highest COP value in the system was obtained at 5 °C evaporation temperature in case of using the refrigerant R600 with 6.593, while the lowest value was obtained as 3.311 when R227ea was used at 50 °C condensation temperature.
