Evaporative cooling is an environmentally friendly and energy efficient cooling method that only uses water as the working fluid to cool air through the simple evaporation of water. It is a technology that could substantially reduce the airconditioning cooling energy requirement in buildings and provide other important environmental benefits. Howev...


... For this reason, they propose a combination of the two configurations. Hui and Cheung [96] found that this combination led to the attainment of cool air better than using one type of evaporative cooler only. The cooling system parameters, such as the pad area, the fan power, the flowrates, the distribution system, and the pump capacity, should be rigorously calculated and selected in order to guarantee the sufficient humidification of the pad, and to avoid pad clogging. ...
