Abstract
A research work on the design, fabrication and evaluation of an active evaporative cooling system was carried out for an optimized storage process and improved modus operandi of the system. The cooler is made of an inner wall and external wall, the inner wall is made up aluminum of 0.6mm thickness and the external wall is made up of galvanized steel of 1mm, the internal and external wall is separated by a lagging material called polyurethane of 25mm, the cooler has 3 trays. The water distribution network of the system contains 2 water tanks of 20liters capacity each, a PVC pipe of 25mm diameter for conveying water, a 0.5 horse power pump for circulating water from the bottom tank to the overhead reservoir and a floater switch for controlling the pump. Water is discharged from the overhead tank through a tap and drains through a pad material called jute bag. as water drips through the pad, a suction fan of 38cm swept depth sets air in motion and blows through the wetted part. As evaporation takes place, there is a cooling effect relatively occurring inside the cooling chamber. The cooler was able to control the temperature to 23.700C relative to the ambient temperature of 29.500C and relative humidity to 95.6%. compared to an ambient Design and Optimization of an Active Evaporative Cooling System relative humidity value of 64.7%. The cooling efficiency of the cooler was evaluated on an average to be 86.01%.
