Abstract
The impact of using TiO2 nano-coated basin and glass cover cooling at different concentrations of 0.1, 0.2, and 0.3% on Traditional Hemispherical Solar Still (THSS) was researched at El Oued City, Algeria. The use of a nano-coated basin and glass cover cooling increases the temperature difference between the nano-coated basin and the glass cover. From the research output, it is found that by adding nano-coated basin at concentrations of 0.1, 0.2, and 0.3% in the HSS, the output distilled water of 4.07, 4.54, and 4.96 kg was obtained. The use of nano-coated basin at concentrations of 0.1, 0.2, and 0.3% with glass cooling in the HSS produced the output distilled water of 4.9, 5.47, and 6.12 kg, respectively. Furthermore, energy and exergy efficiencies are calculated. The daily energy efficiency obtained for the HSS with a nano-coated basin at concentrations of 0.1, 0.2, and 0.3% is found as 33.24, 37.61, and 41%, while the daily exergy efficiency is 2.52, 3.03, and 3.47%, respectively. Similarly, the daily energy efficiency obtained for the HSS with a nano-coated basin at concentrations of 0.1, 0.2, and 0.3% with glass cooling are found to be 40.34, 46 and 51%, while the daily exergy efficiency is 3.32, 4.07, and 4.71%, respectively.
