Heat Pump Efficiency Formula
The following formula is used to calculate the Heat Pump Efficiency.
Ehp = HR / W *100
- Where Ehp is the Heat Pump Efficiency (%)
- HR is the total heat removed by the heat pump (J)
- W is the total work needed to remove the heat (J)
How to Calculate Heat Pump Efficiency?
The following two example problems outline how to calculate the Heat Pump Efficiency.
Example Problem #1:
- First, determine the total heat removed by the heat pump (J). In this example, the total heat removed by the heat pump (J) is given as 594.
- Next, determine the total work needed to remove the heat (J). For this problem, the total work needed to remove the heat (J) is given as 1000.
- Finally, calculate the Heat Pump Efficiency using the equation above:
Ehp = HR / W *100
Inserting the values from above and solving the equation:
Ehp = 594 / 1000 *100 = 59.4 (%)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
total heat removed by the heat pump (J) = 500
total work needed to remove the heat (J) = 600
Entering these values yields:
Ehp = 500 / 600 *100 = 83.33 (%)
