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