Chapter 16, Problem 28P

(a)

To determine

The maximum coefficient of performance of a heat pump that collects thermal energy from the outside air at $\text{5 °C}$

and delivers it to house at $40\text{ °C}$.

(b)

To determine

The amount of heat delivered by the heat pump to the house by using $1000\text{ J}$

of net work, assuming the heat pump is operating at maximum coefficient of performance.

(c)

To determine

The amount of heat delivered by the heat pump to the house by using $1000\text{ J}$

of net work, assuming that the coefficient of performance of the heat pump is $2.0$.
