Abstract

La présente invention concerne une unité intérieure utilisée dans un conditionneur d'air grâce à laquelle l'installation est facilitée du fait qu'un élément assurant le passage d'air vers un orifice de sortie est construit dans un corps d'une enceinte. Dans cette invention, une enceinte définit un corps de l'unité intérieure de telle sorte qu'un orifice de sortie et une partie de guidage de l'orifice de sortie soient réalisés dans un corps de l'enceinte pour guider l'air présent dans l'enceinte afin de le rejeter à l'extérieur par l'orifice de sortie.
