Review on Evaporative Cooling Systems

A review of evaporative cooling systems for air conditioning is presented. The concept, applications, and the factors affecting it were reported. The evaporative cooling systems are grouped into three broad categories, namely, the direct evaporative cooling system, the indirect evaporative cooling system and the combined evaporative cooling system. Also, studies aimed at determining the cooling pad selection and modelling of heat and mass transfer, overall energy balance, direct and indirect cooling was reviewed. Generally, evaporative cooling can be specially applied in dry and hot climates and it’s a simple and least energy consumptive way of achieving air conditioning.
