Asymmetrical Solar Still with Various Basin Materials

Abstract

A solar still is efficient and attractive application of renewable energy (solar) in the distillate production. In this work, the solar still with different basin materials viz; plastic, glass, and galvanized iron (GI) with basin area of 1m x1m and slope of 13○ were fabricated and tested in Anna University, Chennai. The basin materials are taken according to the low cost that is easily available in the local areas. The bottom and side losses of the still are considerably reduced, due to the low cost insulation material (thermcol) beneath the basin liner. The stills are experimentally investigated on a clear day (03/04/2014). Comparison of the various basin materials under the same weather conditions is done. A model economic analysis calculation for the asymmetrical single-basin and single-slope solar still is verified.

Asymmetrical Solar still Coupled with the Mini Solar Pond: Performance Evaluation on Clear, Partially Cloudy and Cloudy Days

“…An experimental investigation was carried out on single-slope solar still without the mini solar pond, with minimum saline water depth of 1.5 cm in basin on clear day (05/06/2014). The bottom and side losses of the still are considerably reduced, due to the porous material beneath the basin liner [14]. The maximum productivity occurred between the hours of 11.30 A.M and 02:30 P.M shown in the Fig.…”
