Experimental and theoretical investigations of traditional solar still productivity in cold climatic

Abstract

Abstract Solar distillation is an important technology to get potable water from saltwater using clean and free solar energy. In the current study, an experimental and theoretical investigation of a single-slope traditional solar still was carried out, and the freshwater productivity and thermal efficiency were evaluated for four typical days (19/06, 17/07, 22/08, and 15/09) of 2019 by implementing temperature parameters in different points of the solar still, and the weather parameters such as solar radiation, and ambient air temperature. The study showed an acceptable agreement between the experimental and theoretical results with an average of 6.6% measured deviation of the experimental data. It was noticed that the highest values of productivity were recorded on July 17, 2019.
