Question:-
A refrigerator working on a reversed Carnot cycle has a C.O.P. of 4. If it works as a heat pump and consumes 1 kW, the heating effect will be
Option (A)
1 kW
Option (B)
4kW
Option(C)
5kW
Option(D)
6kW
Correct Option:
()
Question Solution:
(COP)Heat pump = (COP)Refrigeration + 1 = 4 + 1
(COP)H = 5
And (COP)H = (R/P)
\ R = 5 x 1 = 5kW
