Refrigerant 134 A enters in a condenser of a heat pump at 180 kPa and -4 0C and exits with a quality of 0.8 and the same pressure of 180 kPa. The mass flow rate of the refrigerant is 65 kg/h, and the heat pump compressor consumes 45 kJ/min of power. Determine the coefficient of performance of the heat pump. Type your answer in the first box.
