Question
A residential heat pump uses the ground as an energy source. At a particular operating condition, the heat pump delivers energy at a rate of 13.37 kW to the heated interior while simultaneously removing energy from the ground at a rate of 10.05 kW. Determine (a) the electrical power required to operate the heat pump and (b) the coefficient of performance. A residential heat pump uses the ground as an energy source.

Determine (a) the electrical power required to operate the heat pump and (b) the coefficient of performance.Explanation / Answer
a)the electrical power is
P = P1 - P2
where P1 = 13.37 kW and P2 = 10.05 kW
b)the coefficient of performance is
K = (P2/P1 - P2)
