Abstract

L'objectif de la présente invention est d'obtenir un climatiseur qui présente une liberté améliorée lorsqu'une unité intérieure est installée sur une structure de fondation et qui présente une polyvalence supérieure. Le climatiseur selon l'invention est pourvu d'un cadre de support et d'au moins une unité intérieure. Le cadre de support est fixé à au moins une surface d'une structure de fondation ayant une pluralité de surfaces. L'unité intérieure comprend une soufflante d'air et un échangeur de chaleur qui échange de la chaleur entre un fluide frigorigène et l'air, et l'unité intérieure est supportée de manière amovible par le cadre de support.
