Portable Solar Water Purifier with Heating and Cooling Effect

Mechanical engineering

Water is the most important element for all living organisms on the earth. Without water nothing can survive. As a matter of fact there is only 1% drinking water available on earth. Specially for human being pure water for drinking purpose is very essential as contaminated water cause number of diseases. In this project we have fabricated a device which can not only pure the water but produces the required effect of cooling and heating as per season requirement. Our project is basically to purify water for drinking purpose which is based on ultrafiltration method along with cooling and heating based on Thermoelectric Peltier effect using the Solar panel. We have used Activated carbon filtration and Ultrafiltration (UF) method to purify water which is the most useful technique for water purification. We are using solar panels for charging the battery and used the RC circuit for controlling Peltier module and the pump. As we know that solar energy is a renewable source of energy and It does not affect the environment. In current scenario one of the major issues is power consumption. Refrigerators and air conditioning units using Freon, Ammonia for cooling purpose leads to harmful gas emission, global warming and other environmental hazards. These problems can be overcome by using Peltier modules. A cooling system based on Peltier Effect uses very less power and is portable. It uses a very thin Peltier module through which the required heat transfer can be achieved. These modules are compact in size, light in weight, highly reliable and without working fluid or moving parts, unlike conventional systems.
