Question
A refrigerator uses refrigerant-134a as the working
fluid and operates on the ideal vapor-compression refrigeration
cycle except for the compression process. The refrigerant
enters the evaporator at 120 kPa with a quality of 34 percent
and leaves the compressor at 70C. If the compressor consumes
450 W of power, determine (a) the mass flow rate of the
refrigerant, (b) the condenser pressure, and (c) the COP of the
refrigerator.
