Abstract
The solar energy has been renowned as sustainable energy source Desalination, utilizing solar energy, could be used as part of to the water crisis solution. Potable water can be delivered in solar desalination process using solar distiller. The distiller is one of the simple promising advancements to sanitize water in view of its minimal cost, skill requirements and energy demand.In the present study, a new design of solar distiller with transparent top-cover which made up of glass and a transparent basin made up of poly carbonate. The distiller is designed to be used on the roof of agricultural greenhouses. The fully transparent design allows the sunlight to pass for the necessary photosynthesis process which is required for the growth of the plants. In addition, this distiller uses the extra solar radiation (more than plants needs) to desalinate the water and use this desalinated water for the irrigation of the agricultural crops. The experiment is carried out at The City of Scientific Research and Technological Applications, Borg El Arab (30°52’ North, 29°34’ East), Alexandria, Egypt. Some of important parameters are evaluated during field experiments such as water, glass cover, basin temperatures and distillate output. The experiments are conducted to study the wind speed effect, and effect of atmospheric temperature on the productivity of the solar distiller. On the other hand, a new method is proposed according to which the performance of the fully transparent solar distiller can be assessed. The proposed method consists of two main coupled modules namely: lumped module and CFD module. Lumped module uses transient mass and energy balance equations for glass, water and basin components. The lumped module succeeded in predicting the temperatures of glass, basin as well as water while it failed to predict the productivity of transparent distiller. Therefore, the proposed coupled lumped-CFD model is used to improve the performance estimation of the distiller. The lumped module, the coupled lumped-CFD model, and experimental measurements were compared to validate the accuracy of the numerical models. A parametric study was done to examine the effect of wind speed, basin thickness, and different critical climate conditions, over 33 years of meteorological data, on the solar distiller performance. The numerical study showed a considerable effect of the wind speed on the transparent solar distiller performance. In addition, the maximum productivity occurred in the hottest month which is August, while the minimum.productivity happened in the coldest month which is January according to Borg El Arab, Alexandria, Egypt climate where the present work was done.
