Abstract

La présente invention concerne un dispositif de climatisation (100) permettant la réduction des dimensions du produit. À cet effet, une première sortie (7) souffle, dans une direction latérale, de l'air ayant traversé un radiateur (10), et une seconde sortie (8) souffle, dans une direction latérale différente de l'orientation de l'air soufflé à partir de la première sortie (7), de l'air ayant traversé un évaporateur (12). Un utilisateur peut obtenir de l'air froid ou chaud juste au moyen de la modification de l'orientation du dispositif de climatisation (100). Cette configuration, permettant de souffler de l'air froid et de l'air chaud dans des directions latérales différentes, simplifie un circuit de ventilation, contribuant ainsi à la réduction des dimensions du produit.
