In a refrigeration system the refrigerant R134a leaves the compressor and enters the
condenser at 70°C; also leaves the expansion valve and enters the evaporator
at 20°C and 23% quality; the evaporator is used to cool 0.065 Kg/sec of
liquid water entering the evaporator at 50°C and leaving it at 40°C. (60 points)
Calculate:
a) The heat flux transferred by the water to the R134a in the evaporator.
b) The power of the compressor.
c) The heat flux in the condenser.
