Interpretation:

The heat that can be extracted from a house in a day needs to be determined if the coefficient of performance of the air conditioner is 2.20 and it consumed 1.70×103 W of electrical power.

Concept Introduction:

The Coefficient of Performance ( ηr ) of a reversible Carnot refrigerator is defined as the ratio of the heat withdrawn from the cold reservoir to the work supplied to the device.

  ηr=qcoldw.................(1)

Here,

  ηr: Coefficient of Performance of reversible Carnot refrigerator.

qcold: Heat withdrawn from the cold reservoir.

w: Work is done by the reversible Carnot refrigerator.
