The refrigerant enters the evaporator at -30 °C with a quality of 34% and leaves the compressor at 40 °C. If the compressor consumes 450 Watts of power, establish an engineering model for this problem and determine the mass flow rate of the refrigerant as well as the coefficient of performance of the refrigerator.
