Effect of Design Parameters on Fresh Water Produced from Triangular Basin and Conventional Basin Solar Still

Abstract

This paper reported the experimental testing of a triangular and conventional basin solar still (TBSS and CBSS). Solar basin and absorber are made of glass and a polyethylene cover, respectively, with an area of 0.25 m2. Square and triangular absorber with the same area of 0.25 m2 with square and triangular glass cover for condensation was fixed. Experimentations were conducted during the month of December 2018, and different natural criteria such as intensity, wind speed, and surrounding ambient temperatures were considered. Also, the modified model was compared to the CBSS on its performance and efficiency characteristics. The experimental results also revealed that the temperature of the water inside the TBSS was higher as compared with that of the CBSS. The daily yield obtained from CBSS and TBSS was found to be 2.7 and 3.2 kg/m2, respectively. Also, the daily efficiency of the TBSS was improved by 11.36% than the CBSS.
