Refrigerant 22 is used as the working fluid in an ideal vapor-compression refrigeration cycle. Saturated vapor enters the compresssor at -40°C at a flow rate of 1 kg/s. Saturated liquid exits the condensor at 9 bar.
a) What is the power input to the compressor?
b) What is the refirgeration capacity?
c) What is the coefficient of performance?
d) For the case of irreversible compressor performance to the same exit pressure, will the COP be greater than, less than, or equal to the value in part c) above? (no calculations necessary)
e) For the ideal vapor-compression refrigeration cycle, in which of the four process steps does the working fluid undergo a positive entropy change? (no calculations are needed)
