Fabrication of A Prototype for Condensation of Water on Metal Surface Using Peltier Modules

Abstract

Collection of water is an utmost and important necessity for our survival because 70% of our body is composed of it. The available water on earth can be estimated as 73% but only 10% of which is consumable. The available drinking water sources are from ground and fresh water bodies and rainwater harvesting as well. Here arises a need for better solution for water collection and its purification. Many distillation units are accompanied for filtration of water by evaporation, reverse osmosis and chemical compounds. In all this we always forget to mention another source of water that is the air. Appreciably, the air has a distinct property, i.e. there is some percent of water present in the air. During winter season, fog on car's windshield is because of condensation of water molecules present in the air. Despite being a hard task to extract water from humid air as it is required to cool it below its dew point temperature and it needs high amount of energy input thus it is a necessary to find new sources of energy. Thus there arises a need for research of moderate systems those would work on renewable energy sources like solar energy. Traditional VCRS cycles have harmed the nature since 1970s and despite their modifications there lies a risk for human life. Hence there is a need for other cooling systems like thermoelectric cooling and heating. Thus we had made use of one of the thermoelectric module i.e. peltier module. Currently we fabricated a prototype that is in a development stage for condensation of water.
