Serway & Jewett — Heat Engines, Entropy, and the Second Law of Thermodynamics: Problem 34
Suppose an ideal (Carnot) heat pump could be constructed for use as an air conditioner. (a) Obtain an expression for the coefficient of performance (COP) for such an air conditioner in terms of \(T_h\) and \(T_c\). (b) Would such an air conditioner operate on a smaller energy input if the difference in the operating temperatures were greater or smaller? (c) Compute the COP for such an air conditioner if the indoor temperature is \(20.0^\circ\text{C}\) and the outdoor temperature is \(40.0^\circ\text{C}\).
