Abstract

L'invention concerne une unité intérieure de climatiseur mural (1) comprenant : un boîtier de machine (10) présentant un orifice d'entrée d'air (11) et un orifice de sortie d'air rectangulaire allongé (12) destiné à distribuer un flux d'air dans une pièce, deux déflecteurs indépendants (131, 132) étant disposés au niveau de l'orifice de sortie d'air (12), chaque déflecteur (131, 132) étant agencé pour pivoter autour d'un arbre rotatif de celui-ci parallèlement à une direction d'extension de l'orifice de sortie d'air (12) d'une manière commandée, et les arbres rotatifs des deux déflecteurs (131, 132) étant colinéaires ou parallèles les uns aux autres; et au moins un ventilateur à flux transversal (20) et un évaporateur (30) disposés dans le boîtier de machine, l'évaporateur (30) recouvrant l'au moins un ventilateur à flux transversal (20) et comprenant, de l'arrière vers l'avant, une première section d'échange de chaleur (31), une deuxième section d'échange de chaleur (32) et une troisième section d'échange de chaleur (33) raccordées de manière séquentielle les unes aux autres. La troisième section d'échange de chaleur (33) est une section d'échange de chaleur en forme de V inclinée, à partir de deux extrémités latérales du boîtier de machine (10), en direction du milieu du boîtier de machine dans une direction extérieure à l'opposé de l'au moins un ventilateur à flux transversal (20) progressivement, ou une section d'échange de chaleur incurvée faisant saillie progressivement dans la direction extérieure et s'étendant de manière incurvée, de manière à réaliser une distribution d'écoulement d'air à deux régions multimodale; pour augmenter la zone d'échange de chaleur efficace de l'évaporateur (30), l'efficacité d'échange de chaleur et le volume d'air d'appoint; et pour réduire le bruit de fonctionnement.
