| Abstract | ||||
| Trails were carried out under controllable conditions using solar rays simulator to investigate parameters which affect the performance of four different solar still configurations that used for sea water desalination. Two single slope still angles of 20° and 30° (SSSA 20° and 30°) were compared with other two double slope still angles of 20° and 30° (DSSSA 20° and 30°) configurations. Each still had the same steel basins with the same dimensions of 0.80 m long, 0.50 m wide, 0.10 m high and 2 mm thick. Parameters affects the still productivity and performance of different configurations in terms of glazing area, distance between water surface and the glazing cover and the effect of using three different absorbing materials were considered. Matt black fiberglass, matt black paint covered with 6 mm glass cover thickness and matt black paint only were investigated as absorbing material types. The still performance includes the following determinations: efficiency (η) and the coefficient of performance (C.O.P). The distilled water and its salinity were determined for each solar still configuration. | ||||
