Abstract

L'invention concerne un système d'aération multifonction d'une maison. Un ventilateur (18) est configuré pour distribuer un courant d'air par l'intermédiaire d'une fente (15) disposée autour d'une circonférence d'un cadre de fenêtre (11a), l'ouverture de la fente étant tournée vers le cadre de fenêtre. Suivant que la fenêtre soit fermée ou ouverte, le système d'aération multifonction peut évacuer de la poussière et des gouttelettes d'eau, etc. d'une vitre (12), et si le ventilateur délivre de l'air plus chaud, la rosée, la glace et la neige peuvent être retirés de la vitre (12). Lorsque la fenêtre est ouverte, le courant d'air délivré par le ventilateur (18) par le biais de la fente (15) va fonctionner comme un ventilateur sans pale.
