What is the formula for the coefficient of performance (COP) of a heat pump?.
- A.COP = Qh / W
- B.COP = W / Qh
- C.COP = Qc / W
- D.COP = W / Qc
Model answer
What a good answer should say
- COP = Qh / W
Explanation
Why this works
The coefficient of performance (COP) for a heat pump is defined as the ratio of the heat delivered to the work input. This relationship helps in understanding the efficiency of heat pumps in transferring heat.
