What is Coefficient of Performance of Refrigerator?

The efficiency of a refrigerator or heat pump is given by a parameter called the coefficient of performance (COP).
The equation is:
COP=Q/W
where
Q is the useful heat supplied or removed by the considered system.
W is the work required by the considered system.
