Freon 22 is used as a refrigerant in a vapor-compression refrigeration cycle in the frozen food section of your local supermarket. If the condenser operates at 320 K (saturated liquid leaves the condenser) and the boiler operates at 260 K (saturated vapor leaves the boiler), calculate:

A) The coefficient of performance, if the compressor has an 80% efficiency rating.
B) The quality of the vapor/liquid mixture that leaves the expansion valve.
C) The Carnot Cycle COP assuming that both reservoir temperatures are the same as the temperatures of the boiler and the condenser.
D) Since no real process can ever match the assumptions of the Carnot engine, why is the Carnot engine useful?
