Abstract

On décrit un élément de blocage d'air permettant d'obtenir un appareil de conditionnement d'air haute performance dans lequel la quantité d'air soufflé n'est pas réduite par le courant d'air soufflé circulant dans la direction longitudinale d'une pale (la direction horizontale par rapport à l'écoulement d'air), sur au moins une extrémité de la pale qui, dans la direction haut/bas, contrôle le flux d'air soufflé depuis l'orifice de soufflage. L'élément de blocage d'air empêche l'air circulant le long d'un dispositif de guidage arrière de s'écouler dans la direction longitudinale de la pale. Par ce moyen, l'élément de blocage d'air empêche l'air circulant le long du dispositif de guidage arrière de se disperser vers les côtés, même si ledit air s'écoule vers la partie aval non couverte par les parois latérales ménagées sur le corps principal de l'appareil de conditionnement d'air, ce qui empêche la réduction de la quantité d'air et permet d'améliorer la performance de soufflage d'air.
