Energy efficiency ratio from energy (EER) calculator

EER has units and is not a dimensionless efficiency.

Units

\mathrm{EER} = \frac{\text{Cooling energy}}{\text{Electric energy}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

\mathrm{EER} = \frac{120{,}000}{10{,}000} = 12

Symbol	Meaning	Unit
$\mathrm{COP}_{\text{energy}}$	cooling coefficient of performance using consistent energy units	—
$\text{Electric energy}$	electric input	kWh
$\text{Cooling energy}$	heat removed	kWh

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
