"Cooling efficiency" means an expression of energy or energy performance in items A to C.
Kilowatts per ton (kW/ton) is the total electrical input (kW) divided by the net cooling capacity (in tons).
Coefficient of performance is the net cooling capacity divided by the energy input rate, when both are expressed in the same unit of measure.
"Once-through cooling system" means a once-through system that has been issued a permit by the Department of Natural Resources to use in excess of 5,000,000 gallons of water annually from a groundwater source.
