Abstract

L'invention concerne un appareil de conditionnement d'air comprenant un orifice d'entrée d'air (8) cylindrique destiné à transporter l'air de la pièce, un ventilateur centrifuge (10) destiné à déplacer radialement l'air aspiré par l'orifice d'entrée d'air (8), et un échangeur de chaleur (9) faisant face à un orifice (10b) situé sur le ventilateur centrifuge (10), tous ces éléments étant disposés dans un caisson (2). Une enveloppe (5) du ventilateur centrifuge (10) possède une section guide (5c) située radialement à l'extérieur et de manière contiguë à un support de lame annulaire (5b) pour se projeter vers un côté d'aspiration dans une direction axiale, la section de guidage (5c) réduisant effectivement les bruits de soufflage.
