Abstract
Conventional domestic water coolers found in schools, offices and other public places work on the vapour compression refrigeration system are highly energy-intensive and expensive due to the presence of compressor. An evaporative cooling process is an alternative way to cool the drinking water without the use of external energy in hot and dry weather conditions. This paper illustrates the novel energy-efficient design of water-cooler for a hot and dry climate. The proposed system has lower energy consumptions as compared with the compressor based conventional water cooler. Average drinking water inlet and outlet temperature for the developed system were recorded as 30.50C and 23.060C respectively. The average rate of evaporation of water on jute humidifier was found as 3.116 kg/hr with average heat rejection from the drinking water as 339.73 W. The humidifying efficiency of jute humidifier was estimated as 76.8%. The drinking water at temperature 23.060C was found good for drinking purpose. The coefficient of performance (COP) of the developed system was found as 8.26 with a refrigeration capacity of 0.0968 TR.
