Cooling capacity is the measure of a cooling system's ability to remove heat.[1] The SI units are watts (W). Another common unit is the ton, which describes the amount of water at a given temperature that can be frozen in a given amount of time.[2] [3] 1 ton of refrigeration is the ability of a refrigerator to freeze 2000 lb of water at 0 °C or 32 °F in the period of 24 hours. 1 ton of refrigeration is equivalent to 211 kJ/min or 200 Btu/min.[4]

The basic SI units equation for deriving cooling capacity is of the form:

Where

is the cooling capacity [kW]
is the mass rate [kg/s]
is the specific heat capacity [kJ/kg K]
is the temperature change [K]
