If the coefficient of performance of the refrigerator is 4.67, then what is the value of the coefficient of performance of the heat pump operating under the same conditions?

If the coefficient of performance of the refrigerator is 4.67, then what is the value of the coefficient of performance of the heat pump operating under the same conditions? Correct Answer 5.67

As we know, the equation between the coefficient of performance of the Refrigerator and heat pump: (C.O.P.)R = (C.O.P.)P – 1 Hence, C.O.P. of heat pump = C.O.P. of Refrigerator + 1 = 4.67 + 1 = 5.67.

Two refrigerators M and N operate in series. The refrigerator M absorbs energy at the rate of 1 kW from a body at temperature 400 K and rejects energy as heat to a body at a temperature T. The refrigerator N absorbs the same quantity of energy which is rejected by the refrigerator N from the body at temperature T, and rejects energy as heat to a body at temperature 800 K. If both the refrigerators have the same C.O.P., what is the value temperature T?
A heat pump is used to meet the heating requirements of a house and maintain it at 20°C.
