Abstract

La présente invention concerne une unité d'intérieur pour climatiseur, qui est capable de détecter des informations dans chaque zone de soufflage d'un espace à climatiser avec une augmentation minimale du coût. L'unité d'intérieur pour climatiseur comporte des parties de capteur (2) conectées à celle-ci, chaque partie de capteur (2) étant équipée d'un capteur de présence (3) et d'un capteur (4) de détection de température au sol qui sont fixés à une partie mobile (22) rotative. Le capteur de présence (3) détecte la présence ou l'absence d'une personne dans la direction de détection du capteur de présence (3). Le capteur (4) de détection de température au sol détecte la température de la surface du sol dans la direction de détection du capteur (4) de détection de température au sol. Le nombre de capteurs de présence (3) est identique à celui des capteurs (4) de détection de température au sol, ce nombre étant inférieur au nombre d'orifices de soufflage vers l'espace à climatiser.
