Question
(a) What is the coefficient of performance of an ideal heatpump that extracts heat from $11^{\circ} \mathrm{C}$ air outside and depositsheat inside your hour house at $24^{\circ} \mathrm{C}$ (b) If this heat pumpoperates on 1400 $\mathrm{W}$ of electrical power, what is themaximum heat it can deliver into your house each hour?
Step 1
Step 1: The coefficient of performance (COP) of a heat pump is given by the formula: \[ COP = \frac{Q_H}{W} = \frac{Q_H}{Q_H - Q_C} \] where \(Q_H\) is the heat input, \(Q_C\) is the heat exhaust, and \(W\) is the work done. Show more…
