Design and development of a low cost air cooler

Air Cooler is one of the appliances that keeping the atmosphere cold. The basic concept of water cooling is to find a medium that can handle and transport heat more efficiently than air. Water has a very good ability to retain heat, in the mean time stay in a liquid form. This project is to design and develop a low cost air cooler which can be used in houses and office

Secondary researches have been carried out to collect data regarding the present design of air cooler. Various types of air cooler available in the market have been identified. Ethnographic study and questionnaire survey has been done for understanding the user product interface. The issues related to current air cooler have been found out. QFD and PDS are prepared based on the data collected.

Concepts are generated according to the PDS prepared. Concepts of a air cooler with additional of a separate fan to spread the water in to the air for cooling. Air cooler with a separate fan is selected as the final concept through weighted ranking method. Colours are chosen according to its applications to make it aesthetically good. A working model of the final concept is made using wood.
