| Summary: | The efficient condensing and cooling device, which follows mass and heat transfer process was an evaporative air cooler. A desert air cooler works on this phenomenon. It was mostly suitable for less humid and hot climatic conditions. In such climate, human comfort plays a major role. The Relative Humidity was also less (<60%) which was deviated from human comfort. The desert air cooler serves this purpose and increase the RH percentage in the atmosphere. The oxygen levels go down as the temperature increases, but this purpose cannot be served by evaporative air cooler and no inventions have been made so far to serve this purpose. this paper brings out a concept of improving the heat transfer rate, Efficiency and oxygen transfer by modifying its wet pads with a fin structured pads (wood & cotton) and by replacing the ordinary water with Nano bubbled water (<200 nm) which was generated from distilled water by mechanical stirring. The comparative study was made with the presence and absence of fin structured pads, and with the presence and absence of nanobubled water. |
