How a Cooling Tower Works. A cooling tower is a large heat exchanger unit which provides cooling water to remove heat from a coolant (most often water) that has been used to cool machinery, process fluids, or buildings. When the cooling water meets with air, a small portion evaporates, lowering its temperature.

Get PriceStephen Hall, in Branan's Rules of Thumb for Chemical Engineers (Fifth Edition), 2012. Mechanical Draft Cooling Towers. Most packaged cooling towers use fans to force or draw air through the tower. Countercurrent-induced draft towers are the most prevalent in the process industries, capable of cooling water within just over 1 °C (2 °F) of the wet-bulb air temperature.
Get PriceThe thermal capability of a cooling tower used for air condition- ing is often expressed in nominal cooling tower tons. A nominal cooling tower ton is defined as cooling 3 gpm of water from 95°F to 85°F at a 78°F entering air wet-bulb temperature. At these condi- tions, the cooling tower rejects 15,000 Btuih per nominal cooling tower ton.
Get PriceThe cooling tower is a cooling device, which makes the hot water in the tower be cooled mainly by the evaporative cooling of water. In order to make full use of water resources, reduce the load of urban tap water supply network, and reduce the operating cost, cooling water is treated by cooling tower and recycled.
