Serway & Jewett β Heat Engines, Entropy, and the Second Law of Thermodynamics: Problem 10
An ideal refrigerator or ideal heat pump is equivalent to a Carnot engine running in reverse. That is, energy \(|Q_c|\) is taken in from a cold reservoir and energy \(|Q_h|\) is rejected to a hot reservoir. (a) Show that the work that must be supplied to run the refrigerator or heat pump is \[W = \frac{T_h - T_c}{T_c} |Q_c|\] (b) Show that the coefficient of performance (COP) of the ideal refrigerator is \[\text{COP} = \frac{T_c}{T_h - T_c}\]
π Solution Approach
Find: (a) Show that the work that must be supplied to run the refriger; (b) Show that the coefficient of performance
