Cooling towers originated in the 19th century through the development of condensers for use with the steam engine.[5] Condensers use relatively cool water, via various means, to condense the steam coming out of the cylinders or turbines. This reduces the back pressure, which in turn reduces the steam consumption, and thus the fuel consumption,...

A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature.[1] Cooling towers may either use the evaporation of water to remove heat and cool the working fluid to near the wet-bulb air temperature or, in the case […]

Crossflow is a design in which the airflow is directed perpendicular to the water flow (see diagram at left). Airflow enters one or more vertical faces of the cooling tower to meet the fill material. Water flows (perpendicular to the air) through the fill by gravity. The air continues through the fill and thus past […]

On 16 August 1916,[22] Frederik van Iterson took out the UK patent (108,863) for Improved Construction of Cooling Towers of Reinforced Concrete.[23] The patent was filed on 9 August 1917, and published on 11 April 1918. In 1918, DSM built the first hyperboloid natural-draft cooling tower at the Staatsmijn Emma, to his design. Hyperboloid (sometimes...

In a wetcooling tower (or open circuit cooling tower), the warm water can be cooled toa temperature lower than the ambient air dry-bulb temperature, if the air isrelatively dry (see dew point and psychrometrics). As ambient air is drawn pasta flow of water, a small portion of the water evaporates, and the energyrequired to evaporate […]
