Closed-loop cooling system

Also known as a wet closed-cycle cooling system, a system that circulates water between a steam condenser and a cooling tower to cool steam condensate at a thermoelectric power plant; the circulating water interacts with a counterflow (or crossflow) of ambient air at the cooling tower and is cooled through the principle of evaporation where a small fraction of the water is evaporated. The evaporated amount is continually replaced to maintain the total volume of water in the system. See also Blowdown
