Abstract

L'invention concerne un procédé de commande pour un climatiseur comprenant les étapes suivantes : une unité intérieure reçoit un signal d'arrêt ; fermer une sortie d'air avant (11) et, en même temps, ouvrir une sortie d'air latérale (13) ou maintenir l'état d'ouverture de la sortie d'air latérale (13) ; et après l'attente pendant un temps prédéfini, fermer la sortie d'air latérale (13). Une fois qu'un utilisateur ferme le climatiseur, la sortie d'air avant (11) de l'unité intérieure faisant face à l'utilisateur est immédiatement fermée, de façon à éviter des opérations erronées dues au fait que l'utilisateur peut penser à tort que l'arrêt est réussi et effectue ensuite l'opération d'arrêt. Étant donné que la sortie d'air latérale (13) ne fait pas face directement à l'utilisateur, l'utilisateur ne peut pas observer l'ouverture et la fermeture de la sortie d'air latérale (13), de telle sorte que des opérations erronées de l'utilisateur peuvent être réduites. De plus, la sortie d'air latérale (13) de l'unité intérieure est ouverte, ce qui aide à évacuer la chaleur résiduelle ou le refroidissement résiduel dans l'unité intérieure. L'invention concerne également un climatiseur.
