Consider a real compressor has an isentropic efficiency of 0.82. This refrigeration cycle has a condenser which over cools a liquid to a temperature of 46.3°C and an evaporator temperature of −8.6°C. The mixture changes to a liquid at a temperature of 48.8°C. Determine the coefficient of performance of this refrigerator for the working fluids of R-12,R-134a,and R-410a
