Abstract

Two unit of single basin solar stills were fabricated with the inner dimension of 1m x 0.5m (effective area 0.5 m2), the glass cover was tilted at 10° with respect to the horizontal and twelve copper-constantan thermocouples were installed in the still to measure the temperatures of the glass cover, chamber, water and ambient-air in the side wall, back wall etc. An hourly amount of extracted distilled water with various temperatures and the insolation were monitored for a period of three months. The performance of the still was evaluated by implementing the following effective parameters: (a) internal reflector fixed on the inner wall surface of the solar still (b) without reflector and (c) Internal and External heat transfer. It was observed that (i) the productivity of the solar still was increasing 21 % when using reflector on the inner wall surfaces (ii) the still productivity increases with increasing ambient temperature and decreases in wind velocity, and also the still productivity increases with increasing the temperature difference between glass and water. (iii) The maximum amount of heat loss was observed in the solar still by the combination of convection and radiation heat transfer from glass to ambient.

Keywords: reflector, internal heat transfer, productivity, efficiency, distillation
