Cooling capacity

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 of refrigeration, which describes the amount of water at freezing temperature that can be frozen in a day (24 hours).^[2] ^[3] 1 ton of refrigeration is equivalent to 211 kJ/min or 200 Btu/min.^[1]

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

{\dot {Q}}={\dot {m}}C_{p}\Delta T

Where

{\dot {Q}}

is the cooling capacity [kW]

{\dot {m}}

is the mass rate [kg/s]

C_{p}

is the specific heat capacity [kJ/kg K]

\Delta T

is the temperature change [K]
