Question
A reversible heat pump is required to maintain a temperature of $0^\circ\text{C}$ in a refrigerator while rejecting heat to the surroundings at 300 K. If the heat removed rate from the refrigerator is 25 kW, determine the COP of the machine and work input required. Proceed to determine the overall COP of the system if the power required to run the machine is developed by a reversible engine which operates between higher and lower temperature limits of 650 K and 300 K respectively.
