Question:-
The working temperature in evaporators and condenser coils of a refrigerator are –23°C and 27°C respectively. The COP of the refrigerator is 0.8 of the maximum COP. For a power input of 1 kW, the refrigeration effect produced will be
Option (A)
4 kW
Option (B)
5 kW
Option(C)
8 kW
Option(D)
2.5 kW
Correct Option:
(A)
Question Solution:
Maximum COP = {250 / (300-250)} = 5
Actual COP = 0.8 x 5 = 4
\ Refrigeration effect = 4 x 1 = 4 kW
