Abstract

La présente invention concerne une unité de régulation de l'humidité de forme compacte et d'épaisseur limitée qui est installée avec sa surface arrière faisant face à une paroi. Un boîtier (50) est installé avec sa surface arrière (50b) faisant face à une surface de paroi (WS) le long de la direction verticale. Le boîtier (50) est doté d'une surface avant (50a) opposée à la surface arrière (50b). Un rotor d'adsorption (32) tourne autour d'un premier axe de rotation (32d) qui est incliné par rapport à la surface arrière (50b). Un ventilateur d'adsorption guide l'air pré-adsorption vers le rotor d'adsorption (32), et évacue l'air post-adsorption à partir duquel l'humidité a été éliminée par le rotor d'adsorption (32) en faisant passer l'air à travers le rotor d'adsorption (32) dans une direction le long du premier axe de rotation (32d). Un ventilateur de régénération (35) guide l'air pré-régénération vers le rotor d'adsorption (32), et évacue l'air post-régénération auquel l'humidité a été ajoutée à partir du rotor d'adsorption (32) en faisant passer l'air à travers le rotor d'adsorption (32) dans une direction le long du premier axe de rotation (32d).
