About the Book

Le terme "chauffage solaire de l'air" fait référence à une technologie dans laquelle l'énergie rayonnante émise par le soleil est captée dans un absorbeur et utilisée pour le chauffage des locaux. Il va sans dire qu'il s'agit d'une méthode renouvelable et non polluante de chauffage des locaux, qui peut s'avérer très rentable lorsqu'elle est utilisée dans des bâtiments commerciaux ou des industries. Les aérothermes solaires conventionnels ont une faible efficacité thermique en raison du faible coefficient de transfert de chaleur entre la plaque de l'absorbeur et l'air, ce qui entraîne une température plus élevée de l'absorbeur et donc des pertes thermiques plus importantes. Des tentatives ont été faites pour augmenter le transfert de chaleur vers l'air circulant dans le conduit du chauffe-air solaire en utilisant des absorbeurs à ailettes, des absorbeurs à lit compact, des absorbeurs ondulés, un flux d'air à deux passages, des plaques de verre superposées, des absorbeurs à nervures artificielles, etc. En conclusion, l'étude expérimentale menée pour recueillir des données complètes sur les conduits de chauffage solaire à nervures artificielles a révélé que le fait de rugosifier la face inférieure de la plaque absorbante du conduit de chauffage solaire à l'aide d'une nervure circulaire transversale permet d'améliorer les performances thermiques.
