2. (5 points) Consider an actual vapor-compression refrigeration cycle. R-134a enters the compressor a superheated vapor at 0.20 MPa and -5°C at a rate of 0.05 kg/s, and it leaves at 1.2 MPa and 70°C. The refrigerant is cooled in the condenser to 44°C and 1.15 MPa, and it is throttled to 0.21 MPa.Determine: a. The rate of heat addition to the evaporator, in kVW. b. The power input to the compressor, in kW. c. The isentropic efficiency of the compressor.
