Lorsque l'ouverture d'air est une entrée d'air, le réglage d'une position de guidage d'air de la première partie de guidage d'air (20) et/ou de la seconde partie de guidage d'air (30) peut augmenter la quantité d'admission d'air de l'entrée d'air, de telle sorte que l'unité intérieure peut réaliser une réfrigération et un chauffage rapides, et en outre, l'unité intérieure peut également changer la direction de sortie d'air d'un écoulement d'air au moyen du réglage de la position de guidage d'air de la première partie de guidage d'air (20), de telle sorte que la situation dans laquelle de l'air froid est soufflé directement sur des personnes lorsque l'unité intérieure est dans un mode de réfrigération peut être évitée, et de plus, lorsque l'unité intérieure est dans un mode de chauffage, l'effet d'un écoulement chaud s'écoulant verticalement vers le sol peut également être atteint, ce qui permet d'améliorer efficacement l'expérience d'utilisation d'un utilisateur.
