A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature.
Coolness is an aesthetic of attitude, behavior, comportment, appearance and style which is generally admired. Because of the varied and changing connotations of cool, as well as its subjective nature, the word has no single meaning.
The word coolie, meaning a labourer, has a variety of other implications and is sometimes regarded as offensive or a pejorative, depending upon the historical and geographical context. It is similar, in many respects, to the Spanish term peón, although both terms are used in some countries, with slightly differing implications.
