WebTheir efficiency is measured by a coefficient of performance (COP). Heat pumps are measured by the efficiency with which they give off heat to the hot reservoir, COP heating; refrigerators and air conditioners by the efficiency with which they take up heat from the cold space, COP cooling: WebA refrigerator or a heat pump that operates on the reversed Carnot cycle is called a Carnot refrigerator or a Carnot heat pump. The coefficient of performance (COP) of reversible or irreversible refrigerator or heat pump is given by. COP R = 1/ ( (Q H /Q L )-1) COP HP = 1/ (1- (Q L /Q H )) where. Q H = the amount of heat rejected to the. taxering 210 https://htctrust.com
