Abstract

An experimental investigation and performance enhancement of modified single slope solar still has been conducted to study the effect variable sizes of external condensing units. The external condensing units are fabricated manually and attached to the two vertical (inclined) sides of the still. Experiments have been conducted for a period five days with five different condenser areas and compared with a conventional ceramic solar still. With the increase in external condenser area, distillate yield is found to increase. By providing 26% additional condensing area over the conventional solar still, the relative increase in daily average thermal efficiency of 58% is observed. The additional cost of adding an external condenser is 10%, whereas the addition of distillate yield is 58%, thus reducing the cost of distillate yield significantly.
