Question: By steadily circulating a refrigerant at low temperature through passages in the walls of the freezer compartment, a refrigerator maintains the freezer compartment at

By steadily circulating a refrigerant at low temperature through passages in the walls of the freezer compartment, a refrigerator maintains the freezer compartment at -5C when the air surrounding the refrigerator is at 22C. The rate of heat transfer from the freezer compartment to the refrigerant is 8000 kJ/h and the power input required to operate the refrigerator is 3200 kJ/h. Determine the coefficient of performance of the refrigerator and compare with the coefficient of performance of a Carnot refrigerator operating between the same two reservoirs. What is the power input required by the Carnot refrigerator? Surroundings at 22C (295 K) www = 8000 kJ/h Freezer compartment at -5C (268 K) cycle 3200 kJ/h System boundary
