Cooling tower heat rejection calculation
WebA cooling tower ton is defined as the heat rejection in cooling 3 GPM of water entering at 95°F and leaving the cooling tower at 85°F, with an entering wet bulb temperature of 78°F, which amounts to 15,000 BTUH. The figure below shows the relationship between water and air as they pass through a cooling tower. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONSevap = 1 TONScond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW The equivalent ton on the cooling tower side actually rejects about … See more The process of cooling is called refrigeration.
