:Slovak term: [[Slovenský termín]]
# Heat-transfer device, in which warm water is cooled by evaporation in atmospheric air (WHO 2007).
# An evaporative condenser is a heat exchanger in which a refrigerant is cooled by a combination of air movement and water spray. (Australian Capital Territory Government 2005).

==Explanation==
A cooling tower is an evaporative condenser. Evaporative condensers usually incorporate
an air fan for forced air movement, a circulating water pump, a water spray system and a
cooling coil (World Plumbing Council Working Group 2008)

==Example==
An evaporative condenser in the form of a cooling tower requires water to be sprayed over
the cooling coils to aid the cooling performance. Unlike an air cooled condenser which is
dependent on dry bulb temperature. The capacity of the evaporative condenser is
influenced by the ambient wet bulb temperature. An evaporative condenser requires a
supply of good quality water for its operation. Water is continuously sprayed on to and
evaporated from its cooling surfaces. The cooling capacity of a tower depends primarily on
the surface area of the coils and the temperature difference between the refrigerant and
the substance being cooled (Australian Government Commonwealth Scientific Industrial
Research Organisation 1998).

Note: Evaporative condensers have been implicated in Legionnaires disease and should not
be sited near any ventilation intakes. These systems should be maintained under strict risk
managed processes and backed by active regulatory standards and ongoing testing and
surveillance and periodically drained and disinfected.
