Design & development of a prototype of the layman’s air-cooler

This paper deals with the design & development of a prototype of the layman’s air-cooler. In summer seasons, we require cold water and cooled air because of scorching temperature. Modern appliances fulfilling these requirements need high power and are costly. So, we propose modified simple air cooler, which is portable and is low maintenance machine. Air cooler is one of the major consumers of electrical energy in many parts of the world today. Air cooler causes energy shortage for example in China. The demand can be expected to increase because of changing working times increased comfort expectations and global warming. Air conditioners are pretty expensive themselves and adding to them their power bills makes it out of reach for most common man. So opting for an air cooler is probably one solution which not only is cheaper as an appliance, but also uses lower power than conventional air conditioners. The work presented here is the mini-project work of the second semester engineering students of electronics & communication engineering department of Dayananda Sagar College of Engg., Bangalore, Karnataka
