EXPERIMENTAL STUDY ON AIR COOLING SYSTEM BY USING CONVERGENT NOZZLES

Abstract

Air conditioners (AC) are costly and most of the Indians use evaporative cooling system i.e Desert cooler for cooling on regular basis. However the use of evaporative cooling system is not favorable in all conditions . Because for comfort we have to consider temperature as well as humidity. The climate of India consists of wide range of weather conditions across a vast geographical scale and varied topography , making generalizations difficult. More over India has a wide range of coastal area. The costal area get hotter in summer and it has humidity too . We can’t use evaporative cooling system in these conditions , as it increases humidity which makes the surrounding uncomfortable. Hence, our project aim is to develop an alternative for evaporative cooling and also , to build something which is cost effective and comparatively efficient. In our project rather than using water to reduce temperature which increase humidity, we use nozzles which help in reducing temperature without using water as evaporative cooling system and without using gases as in AC.
