Cooling Load - Convert between kW/ton to COP or EER

2022-4-1 · Absorption chillers are often rated in fuel consumption per ton cooling. Electric motor driven chillers are rated in kilowatts per ton cooling. kW/ton = 12 / EER. kW/ton = 12 / (COP x 3.412) COP = EER / 3.412. COP = 12 / (kW/ton) / 3.412. EER = 12 / (kW/ton) EER = COP x 3.412. If the efficiency of a chiller is rated to 1 kW/ton, then.
