Three types of cooling pad made of a cellulose, aspen fiber, and coconut coir were comparatively studied. This study is performed in summer and based on weather conditions of Bhopal, India; maximum dry bulb temperature of air 41.2 ̊C and 26.1 ̊C wet bulb temperature. The relative humidity of 31.1 % is carried out from online psychrometric calculator. The primary air velocity considered varies between 0.5 m/s to 3.0 m/s and the performance of the cooling pads are analyzed based on the saturation efficiency, leaving air temperature, specific humidity, relative humidity, cooling capacity and water consumption. Graphs are plotted for variation in Saturation efficiency and cooling capacity for different materials of pad with air mass flow...
