Réalisation et expérimentation d'un capteur solaire à eau couplé à un échangeur de chaleur à tubes et à ailettes

Abstract

In this work we are interested in the realization and the experimentation of a hot air production installation intended for the heating of the buildings by solar energy by means of a solar water sensor integrated in a heat exchanger. with tubes and fins. To highlight the effect of operating parameters, such as incident solar irradiance, the mass flow rate of circulating water in the sensor, and the fan power of the tube and fin exchanger on thermal performance. many experiments were carried out under different climatic conditions, which enabled us to follow, as a function of time, the evolution of the outlet temperatures, the quantity of heat produced, the thermal efficiency and the performance coefficient of the installation. Key words: solar water collector, heat exchanger, building heating, solar energy, performance.
