  • the infrared sensor module is installed on the indoor unit of the air conditioner, or a separate infrared sensor device for communicating with the air conditioner, for detecting thermal imaging of the human body and other objects in the room, and the processor executes the program stored in the memory of the air conditioner. According to the thermal image of the human body detected by the infrared sensor module, the temperature value of the surface of the human body is acquired, and the other control of the processor executing the program is the same as the first embodiment of the air conditioner control method of the present invention, and details are not described herein again.

Abstract

L'invention concerne un procédé de commande d'un climatiseur, le procédé consistant : à acquérir des paramètres de hauteur, de poids, d'âge et de sexe d'un utilisateur ; à acquérir une température de rayonnement et une température ambiante dans une pièce ; à déterminer un taux métabolique de l'utilisateur en fonction des paramètres de hauteur, de poids, d'âge et de sexe de l'utilisateur ; à déterminer un paramètre de confort pour l'utilisateur en fonction de la température de rayonnement et de la température ambiante dans la pièce et du taux métabolique de l'utilisateur ; et à commander, en fonction du paramètre de confort, le fonctionnement d'un climatiseur pour l'utilisateur en état de sommeil. L'invention concerne également un dispositif de commande d'un climatiseur, et un climatiseur associé. La présente invention résout le problème des climatiseurs existants, lesquels, lors de la réalisation des manœuvres de commande pour des utilisateurs en état de sommeil, ne prennent pas en considération les taux métaboliques ou acquièrent des paramètres imprécis de taux métaboliques et, par conséquent, les manœuvres de commande effectuées par ces climatiseurs pour les utilisateurs en état de sommeil ne peuvent pas satisfaire les exigences de confort.
