A Review on Investigation of Evaporative cooling

Air-conditioning plays an essential role in ensuring occupants thermal comfort. In order to achieve these comfort Evaporative cooling provide the better solution to conventional vapour compression system. These paper aims to review experimental and theoretical work carried on indirect evaporating cooling along with direct evaporating cooling and combined one. The theoretical direct evaporative cooling work, defines the optimum shape of the cooler as well as the influence of various parameters i.e. primary flow velocity, pad thickness, and flow rate of water on cooling performance. Whereas different constructive parameter of indirect evaporative cooling are also covers in the review. The results of the theoretical data are well agreed with experimental one. Two stage evaporative cooling can be successfully employed to hot and dry climatic area.
