Abstract

Given the increasing consumption of drinking water and agricultural production in the future, as well as the shortage of fossil fuels, it is necessary to use a solar energy source to desalinate salt water. Is. The aim of this study was to investigate the extraction of optimal water production conditions in solar distillation systems in 2019 in four solar distillation systems, in two directions north-south and south-north in the distillation irrigation greenhouse of the Faculty of Water Engineering and Environment of Shahid Chamran University of Ahvaz. The experiments were performed in one month under the conditions (without insulation and closed mirrors; with insulated and closed mirrors; with insulated and open mirrors; without insulated and open mirrors, each in one week). In Abshahr reservoirs, salinity was determined by NACL salt and embedded in reservoirs; The water depth in the reservoirs was fixed and two centimeters. Climatic data were measured to assess the conditions. The results showed that the openness of the mirrors in the tanks with south-north cover slope caused an increase in water production by up to 20% and in the tanks with north-south cover slope caused a decrease in production by up to 38%. Ionolite insulation in tanks reduced production by up to 30%; In all conditions, the south-north direction reservoirs had a lower production rate than the north-south direction reservoirs. Therefore, the closure of the mirrors and the north-south direction were the optimal conditions for water production.
