Génie ClimatiqueTags : stockage thermique énergie solaire eau saumâtre distillation solaire ailettes écart de température thermal storage solar energy brackish water Solar distillation fins temperature difference تخزين حراري طاقة شمسية مياه مالحة تقطير شمسي زعانف فارق درجة الحرارة Index. décimale : 626 Génie Climatique Résumé : To improve the efficiency of simple solar still greenhouse, several experimental work has been made, specifically, active solar still which is a simple solar still coupled with a solar collector where the brine distillation is preheated. To increase the amount of distilled water we studied an active solar still modified with a sensible heat storage tank. Our prototype consists of a simple solar still consisting of a metallic cover which acts as the condenser. A type 'tube' heat exchanger is installed inside the still to heat the brine, a good insulation has been planned at the level of the posterior part of the solar still . As the performance of it is strongly influenced by the temperature difference between brine and coverage of the solar still , with cooling fins are placed on the outside of the cover. Our study we are seeing a significant improvement in the daily production. Our present work is aimed to enrich existing data by mathematical modeling of our prototype based on appropriate heat balances and the use of heat and mass coefficients, with some simplifying assumptions. The purpose of numerical simulation is the optimization of the parameters that affect the production of distilled water, giving an order of magnitude of what thermal storage can make to the proper functioning of a simple solar still

An action to reduce the impact of this sector on the economy and the environment must be undertaken. The use of solar energy is a serious candidate for an effective and sustainable solution. The objective of our work is to carry out a study on the use of solar energy in buildings. The study of different active and passive solar systems and processes that can be integrated has demonstrated the possibility of a large number of solutions. A solar house of the solar village built in Boussaâda is chosen to conduct calculations in three different climates of Algeria. The simulation results of the passive systems show that if the use of passive devices such as solar walls and glazed surfaces can achieve significant energy savings (although considered insufficient), improving the thermal performance of the structure and glazed surfaces according to the passivhauss standard could lead to a greater decrease in heating and cooling needs. A house with low energy consumption is obtained for the cities of Algiers and Constantine. The performance of active systems is also studied. A comparison between different solar collectors to meet domestic hot water needs shows that CPC collectors are the most efficient. Nevertheless, if the electrical production of the hybrid PV/T water collectors is taken into consideration, they present a suitable and elegant solution for a possible integration. These collectors can be chosen to ensure the operation of the absorption and adsorption refrigeration systems and to cover all the energy needs of the solar house. The results obtained further show that the adsorption systems are more efficient than the absorption systems for low power applications. Furthermore the coupling of PV / T collectors with a solar still led to a consequent increase in the production of distilled water.
