Open Recirculated Cooling Water Systems

摘要

Open recirculated cooling water systems remove the heat picked up in a plant by evaporative cooling. This may be done by a spray pond, for example, combining air-conditioning needs with aesthetic consideration in industrial parks. The most common type of evaporative cooling, however, is effected in cooling towers of one type or another. Cooling towers may operate on natural draft, as in the case of wind-cooled towers for small home air-conditioning systems or the large concrete hyperbolic towers used in power-generating stations. In process plants, the towers are more often aided by fans, either forced or induced-draft operations, to improve the cooling capacity.
