Le procédé de commande du climatiseur comprend les étapes suivantes consistant à : lors de la réception d'une instruction de commande d'un mode sans vent, obtenir des vitesses de rotation cibles de la roue de vent avant (12a) et de la roue de vent arrière (12b) dans le ventilateur contrarotatif (12) ; et commander la roue de vent avant (12a) et la roue de vent arrière (12b) pour qu'elles fonctionnent selon les vitesses de rotation cibles, de telle sorte que la différence de vitesse de rotation entre les vitesses de rotation cibles de la roue de vent avant (12a) et de la roue de vent arrière (12b) est supérieure ou égale à une différence prédéfinie. Le procédé de commande décrit peut assurer une alimentation en air rationnelle du climatiseur. La présente invention concerne en outre un climatiseur et un support de stockage lisible par ordinateur.
