Abstract

L'invention concerne un procédé de commande, par ordinateur, d'un climatiseur installé dans une pièce, dans lequel : les informations de position d'un utilisateur dans la pièce ainsi que la profondeur de sommeil, qui représentent les informations de sommeil de l'utilisateur, sont acquises, et si la profondeur de sommeil se trouve dans un premier stade, la direction d'écoulement d'air du climatiseur est commandée de sorte que le vent délivré par le climatiseur évite l'utilisateur sur la base des informations de position (S146) ; et si la profondeur de sommeil se trouve dans un second stade, qui est plus profond que le premier stade, la direction d'écoulement d'air du climatiseur est commandée de sorte que le vent délivré par le climatiseur frappe l'utilisateur sur la base des informations de position (S145).
