Experimental Analysis of a Solar still with Reflectors and Sensible Heat Storage Mediums

Abstract:

Basin type solar stills with top and bottom reflectors are presented and analysed experimentally for three days (23.03.14, 24.03.14, 25.03.14) at Anna University, Thoothukudi campus (8⁰ 48¹ N and 78⁰ 07¹ E), Tamil Nadu, India. Experiments were done simultaneously on four stills with different depths of water. The readings were taken from still with reflectors, still with reflectors and gravel, still with reflectors and pebbles and compared with the conventional still. The reflectors were inclined backwards at an angle of 45⁰. The results indicated that the productivity of the still with reflectors, still with reflectors and gravel and still with reflectors and pebbles was 29.92 %, 38.68 % and 41.60 % more than the conventional still. Also, it was found that the productivity of the still was highest with the minimum depth of water.
