Abstract

L'invention concerne un procédé de commande d'auto-nettoyage pour un climatiseur, comprenant les étapes suivantes : permettre à un dispositif de soufflage de souffler de l'air vers un échangeur de chaleur de l'unité intérieure ; mesurer la concentration de poussière soufflée par le dispositif de soufflage ; et déterminer, en fonction de la concentration de poussière, s'il faut ou non exécuter un mode d'auto-nettoyage. Par comparaison avec la détection directe de la poussière sur l'échangeur de chaleur, la concentration de poussière sur l'échangeur de chaleur peut être mesurée plus précisément par soufflage d'air vers l'échangeur de chaleur, ce qui permet de déterminer avec précision le moment où le climatiseur passe en mode d'auto-nettoyage et d'améliorer l'expérience de l'utilisateur.
