water using less than 0.50 kW per ton of cooling capac- ity. A refrigeration system must also reject chiller compressor by 1% to 2 % in most situations;.
The cooling effect produced is quantified as tons of refrigeration. 1 ton of refrigeration = 3024 kCal/hr heat rejected. The specific power consumption kW/TR is
(b) for refrigeration systems by allowing one ton of refrigeration to equal 3.5 kW (0.35 kW » Kilowatt qui équivaut à 1 000 joules par seconde. ("kW").
