Abstract
A new type solar still (85×70×25cm3) has been constructed, which is called as the “tilted-tray, wick type solar still with a condenser room”. A new material “SOLAR-α” has been utilized as the wick, which was manufactured by UNITIKA LTD. Performance tests have been made under a solar simulator in the laboratory. It was found that (1) the distillation productivity linearly increases in proportion to the irradiation intensity I, (2) there is an optimum saline-water flow rate which results in the maximum productivity, and (3) its value (about 30ml/min per 1m2 evaporating area) is almost independent of I. The additional condenser room, however, has a little effect on the procuctivity, especially in the small I. Discussions have been made on the improvement of the still.
