Abstract

La présente invention concerne un climatiseur conçu de sorte que la fuite d'eau condensée provoquée par le contact entre une canalisation située sur un côté de l'échangeur de chaleur et des conduites d'entrée/sortie de réfrigérant puisse être empêchée. Un climatiseur comprend : un échangeur de chaleur (5) disposé à l'intérieur d'un logement ; et une plaque latérale (18) montée sur une partie de surface latérale de l'échangeur de chaleur. La plaque latérale est dotée d'un élément de division (30) permettant de séparer la partie de surface latérale de l'échangeur de chaleur des conduites d'entrée/sortie de réfrigérant (13) montées sur l'échangeur de chaleur. Le contact des conduites d'entrée/sortie de réfrigérant avec la canalisation (comprenant une conduite courbée, etc.) sur la surface latérale de l'échangeur de chaleur est évité par la présence de l'élément de division, et il est par conséquent empêché que l'eau condensée générée sur la canalisation sur la partie latérale de l'échangeur de chaleur ne s'écoule le long des conduites d'entrée/sortie de réfrigérant et ne soit évacuée vers l'extérieur du climatiseur.
