3. A refrigerator uses refrigerant -134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for compression process. The refrigerant enters the evaporator at 120 kPa wit a quality of 34 % and leaves the compressor at 70 °C. If the compressor consumes 450 W of power, determine: a) The mass flow rate of the refrigerant, b) The condenser pressure, c) COP of the refrigerator, Expansion valve 120 kPa x = 0.34 2H Condenser Evaporator Warm environment Cold 70°C in Compressor environment
