Extracting Water from Air Using E-Waste of Refrigerator in Combination with Thermo Electric Material

Abstract

Water is the pulse of any human society. Without clean water human society cannot survive in this world. To fetch one bucket of water people walk many kilometres in Africa. But the available water is contaminated causing dieses and death in children. India generates large amount of e waste including refrigerator. In this paper an attempt was made to extract water from air by using e waste. the air is first filtered and passed in to the compressor. The compressor compresses the air and passes in to the condenser where the temperature of air decreased suddenly. This action results in the formation of ice in the system. The ice melts and gets converted in to water. To increase the conversion ratio peltier effect is incorporated. The water that is extracted is purified by UV rays and tested for drinking purpose. The results prove that the water can be used for utilized for drinking. The system was designed in such, that 10 litres of water can be extracted in 24 hours at a room temperature of 30 degree Celsius with cost of production at 0.15USD.
