In a home heat pump, heat is absorbed from the earth by a fluid circulating in buried pipes and delivered to the home interior. Suppose that the heat pump is 40% as efficient as a Carnot refrigerator. If the ground surrounding the pipes is at 5`C and the interior temperature of the house is kept to 20`, how many kilowatt-hours of heat would be supplied to the home interior for ever kilowatt-hour of electrical energy needed to operate the refrigerator?(adsbygoogle = window.adsbygoogle || []).push({});

omega = .4

[itex]\ Q_C=20 C [/itex]

[itex]\ Q_H=5 C [/itex]

[itex]\omega = Q_C/W [/itex]

Well we can solve for the work but were looking for kilowatt-hours,

E=Power X time.

Can someone lead me in the right direction and provide the general equation suited for this problem?

Thanks
