Abstract

L'invention porte sur un climatiseur, qui comporte une aube d'altération de direction de vent verticale (12) qui altère verticalement l'orientation d'air soufflé vers l'extérieur à partir d'une ouverture de soufflage vers l'extérieur (10) ; l'aube d'altération de direction de vent verticale (12) comporte une aube inférieure (18) et une aube supérieure (20) qui sont disposées de façon à pouvoir tourner au voisinage de l'ouverture de soufflage vers l'extérieur (10) ; l'aube supérieure (20) est configurée de manière à être apte à se déplacer de manière à se rapprocher ou à reculer vis-à-vis de l'aube inférieure (18), et est configurée de manière à ajuster l'espace entre l'aube inférieure (18) et l'aube supérieure (20) et l'espace entre l'aube supérieure (20) et un stabilisateur (32) formant une ouverture de soufflage vers l'extérieur (10) tournée vers l'aube supérieure (20) ; et pendant le chauffage, la quantité de vent dans l'opération de climatisation est commandée de manière à être accrue au fur et à mesure que l'espace entre l'aube supérieure (20) et l'aube inférieure (18) positionnées en parallèle se rétrécit.
