Question:

In comparing the performance of a real cycle with that of a Carnot cycle, one has in principle a choice of temperatures to use for the Carnot calculation. Consider a vapor-compression refrigeration cycle in which the average fluid temperatures in the condenser and evaporator are TH and TC, respectively. Corresponding to TH and TC, the heat transfer occurs with respect to surroundings at temperature TσH and TσC . Which provides the more conservative estimate of ωCarnot: a calculation based on TH and TC, or one based on TσH and TσC ?
