Improvement of thermo-aeraulic comfort with integrated solar wall system under Saharan climate

Abstract

The aim of this paper is devoted to an example of a concrete application in the bioclimatic architecture: integration of a simple solar air collector in building facades under Saharan climate. The originality of this work is to lift a serious problem that is often encountered in the summer when the indoor air cooling mode through natural ventilation becomes ineffective. We showed that the specific architectural integration of solar air collectors can bring a positive support to the thermo-aeraulic comfort by controlling the mass flow rate of the air entering to the heated building zone in cold season. The major inconvenience of this technique is often encountered in summer. To ensure the reliability of this technique that is sometimes regrettable, it is first necessary to control automatically the opening and closing the air ventilation valve.
