Thermo-Energy Transfer Optimization of a Solar Distiller with Energy Storage Under Bou-Ismail Climatic Conditions

Seawater desalination techniques are sustainable, but their use is limited in rich countries. However, in recent years, the capacity of desalination stations has greatly increased and production costs by m3 experienced a sharp decline. Seawater and brackish water desalination using solar energy witnesses a growing interest in some developing countries. Solar distillation is a technically feasible, simple, profitable, and operational method for the production of freshwater. This thermal process is a key to future water problems in the water poorest regions, namely arid and isolated sites in southern Algeria as it permits to desalinate brackish water and treated wastewater reuse concentrated salt. The aim of this study is to evaluate the effect of temperature and the internal components of solar still on its operation. An experimental examination of a solar distiller performance is realized and designed by a team of research of UDES. The daily instantaneous and global yield will be examined to show the temperatures’ influence on the different distiller elements as well as on the quantity of distillate produced. Also, a comparison of different geometries with energy storage has been undertaken in order to study the influence of geometry on the production of distilled water.
