9.6. 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 T and Tc, respectively. Corresponding to Tμ and
To the heat transfer occurs with respect to surroundings at temperature To and Toc
Which provides the more conservative estimate of @Carnot: a calculation based on TH
and To or one based on To and Toc?
