Aggrandizement in the Performance of Double slope Solar Still with the Incorporation of Peltier Effect in Addition To Water Depths

Abstract

Because of continuous increment in the world population and pollution, the scarcity of water has been increasing constantly. Many researchers are doing research in the field of desalination to convert the impure or soar water into drinkable water. Even though many methodologies were followed, desalination using solar still is the oldest and less cost concept with higher lifetime. So research in this field is still undergoing by enhancing the distillate production by incorporating advanced technologies, by controlling the factors affecting the distillate production and introducing various designs. In this work, the double slope solar still had been used and the performance was found at 1 cm and 0.5 cm water depth. In addition to that, the introduction of Peltier module in the back side of the absorber plate had been fixed to generate the electricity during the day time due to the temperature difference in the Peltier module to charge the battery. The stored current is again used to activate the Peltier to increase the heat generation during the evening time. The performance was increased in both 1 cm water depth and 0.5 water depth by 13% and 9.1% respectively during the heating period in the evening hours.
