Abstract

L'objectif de la présente invention est de proposer un dispositif de circulation d'air qui est pourvu d'un passage de collecte de gouttes d'eau et qui peut ainsi collecter des gouttes d'eau. La présente invention comprend : un logement dans lequel un élément d'échange thermique est logé ; un orifice d'admission qui est formé dans le logement afin d'être positionné sur le côté amont de l'élément d'échange thermique ; un orifice d'évacuation qui est formé dans le logement afin d'être positionné sur le côté en aval l'élément d'échange thermique ; et un tuyau d'évacuation qui est raccordé, à une extrémité, à l'orifice d'évacuation et qui s'étend au moins partiellement le long d'un corps humain. De l'air qui est aspiré dans le logement à partir de l'orifice d'admission est évacué à partir de l'orifice d'évacuation vers le tuyau d'évacuation tout en absorbant de la chaleur à partir de l'air par l'intermédiaire de l'action endothermique de l'élément d'échange thermique, et l'air de refroidissement à partir duquel l'humidité contenue dans l'air a été éliminée par l'intermédiaire de l'action endothermique de l'élément d'échange thermique est ainsi fourni au corps humain, et un passage de collecte de gouttes d'eau qui collecte des gouttes d'eau générées en conséquence de la déshumidification est formé en dessous du logement.
