An experimental study into the operation of a solar chimney used for the improvement of natural ventilation in buildings / Mohammed Bouhedja 

Public ISBD Titre : An experimental study into the operation of a solar chimney used for the improvement of natural ventilation in buildings Type de document : texte imprimé Auteurs : Mohammed Bouhedja, Auteur ; I. C. Ward, Directeur de thèse Editeur : Sheffield : University of Sheffield Année de publication : 1987 Importance : 145 f. Présentation : ill. Format : 30 cm. Note générale : Mémoire de Master : Génie Civil : Sheffield, University of Sheffield : 1987 Annexe f. 146 - 166 . Bibliogr. [8] f Langues : Anglais (eng) Mots-clés : Buildings Ventilation Solar  chimney Cooling  technique Index. décimale : Ms00587 Résumé : In hot countries building densities are usually high, so as to minimize the heat gain from solar radiation. As a result the air motion through and around buildings is reduced. Thus the prime role which natural ventilation can play in cooling buildings is affected. In order to promote natural ventilation and hence induce passive cooling of the buildings the use of a solar chimney has been introduced. The present study is aimed at improving the performance of a solar chimney by increasing the airflow rate using valves to control both the chimney temperature and the flow rate. The author suggests that this method could be applied to buildings in the Southern part of Algeria. First, an analysis of the main meteorological components of the Algerian climate, which enables builders and designers to define the heating and cooling energy resuirements of buildings, is carried out. The results of this analysis are then used to define the boundaries of the different passive coolung strategies recommended for each region. A review of the work done on the use of the different passive cooling techniques related to buildings is then carried out, emphasizing the role which natural ventilation plays in restoring comfortable conditions. The experiments conducted and the adopted techniques are then presented, and the experimental programme implemented to establish the optimum design of a low cost solar air heater, and the effect of alternatively closing and opening of the solar chimney on the airflow rate. Finally, an operating cycle in which the airflow rate is increased above the mean value when the panel is running free is suggested.
