Investigation of the combined effect of mirror and insulation on the amount of water produced in the greenhouse by distillation irrigation

Abstract

The aim of this study is to investigate the combined effect of insulation parameters, mirrors as well as the amount of water added to tanks on the amount of water production in solar distillation systems. For this purpose, the present study in 2020 in four solar distillation systems, in two directions north - south and south - north, which is installed on the roof of the greenhouse distillation irrigation; It was performed in the Faculty of Water and Environmental Engineering of Shahid Chamran University of Ahvaz. The experiments were evaluated in two weeks under the conditions (presence of insulation and closed mirrors; presence of insulation and openness of mirrors; each case in one week). The water depth in the tanks was constant and two centimeters. The results showed that in the presence of ionolite insulation, the openness of the mirrors in the tanks with north-south cover slope caused a decrease in production by up to 10% and in tanks with south-north cover slope caused an increase in production by up to 26%. The openness of the mirrors in tanks with a slope of the north-south cover reduces the rate of evaporation and thus reduces the amount of water added by up to 8%; And in reservoirs with south-north cover slope caused a decrease of up to 2%. The optimal conditions for the experiments were if the mirrors were closed in the north-south direction and the mirrors were open in the south-north direction.
