Cooling towers are used to reject heat from chillers and industrial cooling systems. Proper cooling tower sizing ensures efficient heat rejection and system performance.
Heat Rejection (BTU/hr) = 500 × GPM × ΔT
Cooling Tower Capacity (TR) = BTU/hr ÷ 12,000
Water Flow = 500 GPM
Temperature Difference = 10°F
Cooling Tower Load ≈ 20.8 TR
This calculator helps HVAC engineers estimate cooling tower capacity required for chiller plants.
Cooling tower capacity represents the amount of heat that the cooling tower can reject from the circulating water system.
ΔT represents the temperature difference between hot water entering and cold water leaving the cooling tower.
Correct sizing ensures efficient heat rejection, energy savings and proper chiller plant performance.
Cooling towers are widely used in power plants, HVAC chiller plants, chemical industries and manufacturing facilities.
