Abstract

La présente invention appartient au domaine technique des climatiseurs, et vise à résoudre le problème du faible effet de stérilisation des climatiseurs existants. Par conséquent, sont fournis un procédé de commande de stérilisation pour un climatiseur, et un climatiseur. Une unité intérieure du climatiseur comprend une coque, un déflecteur d'air, un ventilateur et une lampe de stérilisation, la lampe de stérilisation étant disposée dans un conduit d'air de la coque. Le procédé de commande de stérilisation consiste à : déterminer si des conditions préétablies sont satisfaites ou non ; si les conditions préétablies sont satisfaites, acquérir respectivement la température actuelle dans une pièce et une température cible établie par un utilisateur ; et en fonction de la température actuelle et de la température cible, amener de manière sélective un climatiseur à exécuter un mode de stérilisation en profondeur, l'étape consistant à "amener un climatiseur à exécuter un mode de stérilisation en profondeur" comprenant spécifiquement : la fermeture d'un déflecteur d'air et/ou la réduction de la vitesse de rotation du ventilateur à une première vitesse de rotation préétablie. Au moyen d'un tel agencement, le climatiseur est amené de façon intermittente à exécuter le mode de stérilisation en profondeur, et le temps de contact entre un flux d'air et la lampe de stérilisation est prolongé, de façon à effectuer une stérilisation en profondeur sur le flux d'air, de telle sorte que l'effet de stérilisation du climatiseur peut être amélioré.
