Problem: How would you increase the coefficient of performance of an ideal refrigerator?a) Increase the mechanical work input.b) Decrease the outside temperature.c) Decrease the inside temperature.d) Increase the outside temperature.

FREE Expert Solution

Coefficient of Performance, COP:

COP = QCW=QCQH-QC=TCTH-TC

QC is the heat removed from inside and W is the work done. The two must be equal for the coefficient of performance to be 1. 

QH is the heat supplied by the hot reservoir/outside. TC is the temperature of the cold body and TH is the temperature of the hot body.
