T = T2 = Low temperature (TL) T4 = T3 = High temperature (Th) s1 = s4 = Entropy during expansion process s2 = s3 = Entropy during compression process

Consider, for example, a Carnot refrigeration cycle that is used to maintain a space temperature of 40°F and rejects heat at a temperature of 90°F. To calculate the Carnot COP, the temperatures would first be converted to degrees Rankine by adding 460° to each. COP would then be calculated as follows:
