QUESTION 9 Refrigerant-134a enters the evaporator coils placed at the back of the freezer section of a household refrigerator at 100 kPa with a quality of 20 percent and leaves at 100 kPa and -26°C. If the compressor consumes 600 W of power and the COP of the refrigerator is 1.2, determine: (a) the mass flow rate of the refrigerant and (b) the rate of heat rejected to the kitchen air.
