Abstract

L'invention porte sur un procédé et un appareil régulant le flux d'air dans la partie intérieure aux locaux d'un conditionneur d'air pendant une phase de chauffage de manière à uniformiser la distribution des températures dans le local sans donner l'impression de courants d'air. L'appareil comporte une soufflante (3) dont l'axe est dans le sens de la profondeur du boîtier soufflant l'air aspiré sur le côté frontal à l'extérieur dans le sens radial par rapport à l'axe, et un échangeur de chaleur (5) placé dans le boîtier sur le côté frontal de la soufflante (3). Le boîtier est muni d'une sortie d'air soufflant l'air de la soufflante (3) en haut, en bas, à droite, et à gauche. Pendant le chauffage, une commande de volet (10a) envoie des signaux au moteur pas à pas (41) de commande du volet supérieur et au moteur pas à pas (44) de commande du volet gauche, ce qui réduit le degré d'ouverture des volets du haut, de droite et de gauche et accroît celui du volet du bas qui devient plus important que les autres.
