A new design of a single slop double- basin solar still (SSDBS)‎

الملخص EN

A new type of a single slope double- basin solar still have been designed and manufactured ; in order to compare its productivity with that of a single basin solar still, an experimental investigation was carried out on two single slope solar stills with different basin under actual field conditions ; where the first still is conventional solar still with horizontal basin of 0.25m2 while the basin of the second still (the new design) has two partitions ; horizontal basin of 0.1m2 and vertical basin of 0.15m2.

From the experimental results, it has been observed that there is significant enhancement in daily output due to the basin deviation on a clear day.

The main advantages of the vertical partition of the basin are that the latent heat of vapor condensing over the inner surface of the still is utilized in heating the water in the vertical partition of the basin which leads to store the hot water for the continuity of vapor at night also the vertical partition of the basin helps to concentrate the sun ray on it by any type of external reflector to increase the productivity.
