Abstract

L'invention porte sur un climatiseur du type encastrable au plafond dans lequel une entrée d'air (15) et une sortie d'air (16) s'ouvrant pendant une opération de refroidissement ou de chauffage sont ménagées dans un panneau décoratif (14), à la base du climatiseur (1) faisant face à un espace intérieur. Un volet mobile horizontal (18) guide l'air conditionné, dans la direction d'alimentation, depuis la sortie d'air (16), à approximativement 45° au plus relativement à la surface inférieure d'un panneau de plafonnage (70), en modifiant verticalement la direction d'alimentation en air. Un élément d'espacement (72) est placé entre le panneau décoratif (14) et le panneau de plafonnage (70) pour séparer la partie de bord supérieur de la sortie d'air (16), 45 mm au moins vers le bas, du panneau de plafonnage (70). Une surface extérieure inclinée (14a) prolonge la partie de bord supérieur de la sortie d'air (16) dans le panneau décoratif (14) en direction du côté périphérique extérieur de la gaine (10), selon une assiette longitudinale υ d'au moins 10°, de manière à approcher la surface inférieure du panneau de plafonnage (70). La partie de bord supérieur de la sortie d'air (16) est séparée de la position limite, sur une distance d'au moins 75 mm, entre le climatiseur (1) et le panneau de plafonnage (70).
