Abstract—The phenomenon of evaporative cooling is a common process in nature, whose applications for cooling air are being used since the ancient years. In fact, it meets this objective with a low energy consumption, being compared to the primary energy consumption of other alternatives for cooling, as it is simply based in the phenomenon of reducing the air temperature by evaporating water on it. This process can be an interesting alternative to conventional systems in these applications where not very low temperatures are needed, like the case of air-conditioning during the summer. In this paper various types of direct and indirect cooling methods are reviewed to understand the various ways to attain cooling by these methods and provide alternative.
