A heat pump absorbs heat from the atmosphere at a rate of 30 kW. If work is being done to run this heat pump at a rate of 7.7 kW, what is the coefficient of performance (COP) of the heat pump?
A) 2.9
B) 3.9
C) 22
D) 0.26
E) 4.9

Question

Quizplus · Accepted Answer

The coefficient of performance (COP) of a heat pump is defined as the ratio of the heat output to the work input. In this case, COP = Heat absorbed / Work done = 30 kW / 7.7 kW = 3.896 or approximately 4.9.
