A vapor compression refrigeration cycle uses R-22 and follows the theoretical single-stage cycle. The condensing temperature is 48 oC, and the evaporating temperature is –18 oC. The power input to the cycle is 2.5 kW, and the mass flow rate of refrigerant is 0.05 kg/s. Determine (a) the heat rejected from the condenser, (b) the coefficient of performance, (c) the enthalpy at the compressor exit, and (d) the refrigerating efficiency.
