Question: 8 - 3 A vapor - compression refrigeration cycle uses R - 1 3 4 a . Liquid at 1 2 0 0 kPa exits

8-3 A vapor-compression refrigeration cycle uses R-134a. Liquid at 1200 kPa exits the condenser at 40C.
The evaporator operates at a pressure of 240 kPa . The compressor isentropic efficiency is 75%. Determine
the cycle coefficient of performance (COP) if the refrigerant leaves the evaporator as superheated vapor at
0,5,10,15, and 20C above the saturation temperature.
