### Calculating Cooling Loads

Cooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = kW. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heatequivalent of the energy needed to drive the chiller's compressor. This equivalent ton is defined as the heat .
