| Abstract | ||
| Study aims to overcome low productivity of solar still by using cellulose cooling pad and water sprinklers to increase water evaporation. Three identical solar stills were used under climatic conditions of Egypt at Ismailia city. Solar stills were designed, installed, and tested at the Agricultural Engineering Department, Faculty of Agriculture, Suez Canal University, Ismailia Governorate, Egypt. The solar still basin made of galvanized iron sheet, with a net upper surface area of 1.04 m2. A clear glass cover of 3 mm thick was placed and inclined by a tilt angle of 31○. It was painted with matt black paint to absorb the maximum possible amount of solar radiation incident on it. The first conventional solar still was used as a control unit (S1). The second still was functioned with the cooling cellulose pad (S2). The third still was operated with the water sprinklers to spray saline water (S3). For the duration of the experimental tests, the hourly average volumetric thermal efficiency was 31.5, 40.1 and 44.2 % for the S1, S2 and S3, respectively. | ||
