Abstract

L'invention concerne un conditionneur d'air qui tout en permettant d'améliorer l'opérabilité lors de l'entretien ou dans une opération de raccordement de tuyaux lors de l'installation, ne nécessite pas de modifications structurelles superflues ni de grandes dépenses. Ce conditionneur d'air (1) est équipé d'une carrosserie (2) verticalement longue. Un échangeur thermique intérieur et un bac de vidange sont disposés dans la moitié supérieure de l'intérieur de ladite carrosserie (2). Un ventilateur intérieur (5) est disposé dans la moitié inférieure, et des tuyaux de frigorigène (17, 18) provenant de l'échangeur thermique intérieur ainsi qu'un conduit de vidange (19) provenant du bac de vidange se prolongent dans cette moitié inférieure le long des surfaces latérales de la carrosserie (2). Le conditionneur d'air (1) est connecté à un tuyau provenant de l'extérieur à proximité d'une grille d'aspiration (3B) agencée des deux côtés droite et gauche d'un panneau d'aspiration situé sur la surface avant de la moitié inférieure de la carrosserie (2). La grille d'aspiration (3B) côté où se prolongent au moins les tuyaux de frigorigène (17, 18) et le conduit de vidange (19), est installée de manière à ce que son extrémité latérale interne puisse tourner côté externe avec son extrémité latérale externe pour point d'appui.
