Abstract :In this study, energy and exergy analysis of a cascade refrigeration system was carried out. It is assumed that the refrigeration load is 1 kW. The temperature in condenser has been used between 50 ËšC to 60 ËšC, and the temperature in evaporator was changed between -30 ËšC to -40 ËšC. Refrigerant couples used in the cascade refrigeration system are R134a-R404A, R134a-R407C, R404A-R410A, R404A-R507, and R407C-R410A. These refrigerant couples are new generation refrigerant couples that are non-destructive to environment and to the ozone layer. The COP values and irreversibility values of the cascade refrigeration system were determined. In all cases, the refrigerant couple R134a-R407C has the highest COP and lowest irreversibility.
Keywords : Cascade refrigeration, Thermodynamic analysis, COP, exergy
