Abstract

Cette invention se rapporte à un climatiseur qui est capable de commander la direction de soufflage de l'air climatisé pendant son fonctionnement, ainsi qu'à un procédé de commande correspondant. Ce climatiseur (1) comprend une section de commande (60), laquelle est connectée à un compresseur (21), à une vanne de commutation à quatre voies (22), à un décompresseur (25), à une mémoire ROM (41), à une mémoire RAM (42), à un moteur de ventilateur (13), à un moteur de volet (146), à un capteur de température (43) et à un capteur de rayons infrarouges (44). La section de commande (60) commande le compresseur (21), la vanne de commutation à quatre voies (22), le décompresseur (25), le moteur de ventilateur (13) et le moteur de volet (146). Lorsqu'une instruction visant à effectuer un fonctionnement sous forte puissance est introduite depuis un contrôleur distant (40), la section de commande (60) augmente temporairement la vitesse de rotation d'un ventilateur à flux transversal (12) et la fréquence de fonctionnement du compresseur (21), afin d'accroître la capacité de climatisation, et elle commande la direction d'un volet horizontal (144), en considérant la position des personnes dans la pièce.
