The coefficient of performance (C.O.P.) of a refrigerator working as a heat pump is given by
A
(C.O.P.)<sub>P</sub> = (C.O.P.)<sub>R</sub> + 2
B
(C.O.P.)<sub>P</sub> = (C.O.P.)<sub>R</sub> + 1
C
(C.O.P.)<sub>P</sub> = (C.O.P.)<sub>R</sub> - 1
D
(C.O.P.)<sub>P</sub> = (C.O.P.)<sub>R</sub>
Correct Answer: (C.O.P.)<sub>P</sub> = (C.O.P.)<sub>R</sub> + 1
The coefficient of performance (C.O.P.) of a refrigerator working as a heat pump is given by (C.O.P.)P = (C.O.P.)R + 1
