Measured chiller kW/ton calculator

Express the reference's chiller kW/ton performance measure as measured input divided by cooling output.

Units

\mathrm{kW/ton} = \frac{P_{\text{input}}}{Q_{\text{cooling}}}

Calculator

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

Given

\mathrm{kW/ton} = \frac{168}{280} = 0.6

Symbol	Meaning	Unit
$\mathrm{kW/ton}$	electric input per cooling output	kW/ton
$P_{\text{input}}$	measured electrical input	kW
$Q_{\text{cooling}}$	measured cooling output	ton

Symbol	Meaning	Unit
$\mathrm{EIR}$	electric input per cooling output	kW/kW cooling
$P_{\text{input}}$	measured electrical input	kW
$Q_{\text{cooling}}$	measured cooling output	kW cooling

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