9.3.Coefficient of performance of a Refrigerator
The coefficient of performance (C.O.P) is the ratio of heat extracted in the refrigerator to the work done on the refrigerant. It is also known as theoretical coefficient of performance.

Q
C.O.P. = ----------- = Heat extracted
W

Q = Amount of heat extracted in the refrigerator (or the amount of refrigerator produced or the capacity of a refrigerator)
W = Amount of work done
