A heat pump has a coefficient of performance of 3.85 and operates with a power consumption of 7020 W. How much energy does it deliver into a home during 1 h of continuous operation?

97.3 MJ

Explanation:

The formula for the coefficient of Perfomance is given as

COE = Q/W, where

COE is the coefficient of Perfomance

Q is the heat provided

W serves as the work input.

Dividing both sides of the equation by a factor of time t, we get the coefficient of Perfomance in terms of heating power and input power, so we say

COE = P / P(i),

making heating power, P the subject of formula, we have

P = COE * P(i)

P = 3.85 * 7020 * 1 * 3600

P = 97297200 J

P = 97.3 MJ
