Lorsque le climatiseur fonctionne de façon stable, la température ambiante entre l'échangeur de chaleur et le ventilateur du climatiseur est obtenue, et lorsque le rapport de la température ambiante à la température prédéfinie se situe dans la plage de rapport prédéfinie, le temps de démarrage de l'opération d'auto-nettoyage du climatiseur est déterminé en fonction de la relation d'amplitude entre l'humidité ambiante sur la surface de l'échangeur de chaleur et l'humidité ambiante prédéfinie, de telle sorte qu'une synchronisation appropriée pour démarrer l'auto-nettoyage du climatiseur peut être mieux déterminée. La présente demande concerne également un appareil de commande utilisé pour l'auto-nettoyage d'un climatiseur, et le climatiseur.
