A refrigerator maintains a freezer compartment at 250 K while rejecting heat to the surroundings, which are at 300 K. 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.
