A condenser of refrigeration system rejects heat at the rate of 120 kW, while its compressor consumes a power of 30 kW. The coefficient of performance of the system will be

A. $$\frac{1}{4}$$

B. $$\frac{1}{3}$$

C. 3

D. 4

Answer: Option D

Solution (By Examveda Team)

The coefficient of performance or C.O.P. (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work required.
$${\text{C}}{\text{.O}}{\text{.P}}{\text{.}} = \frac{{120\,{\text{kw}}}}{{30\,{\text{kw}}}} = 4\,{\text{kw}}$$

(COP)R = (120 -30)/30 =3
So option C will be the right answer.
