Abstract

La présente invention concerne un système de purification d'air et un dispositif de traitement de fumée qui sont capables, même dans un bâtiment ordinaire, de désodoriser et de purifier l'air intérieur sans dégrader les environnements de vie et de travail. Un système de purification d'air (1) destiné à purifier l'air dans un bâtiment (S) possède un organe d'aspiration destiné à aspirer l'air dans le bâtiment (S) et un organe de purification destiné à purifier l'air aspiré par l'organe d'aspiration. Cet organe d'aspiration possède une partie aspiration (10) située dans le bâtiment (S), à un endroit où il est nécessaire d'aspirer l'air, un passage d'air (2) dont une extrémité est connectée à la partie aspiration (10) et l'autre extrémité est connectée à l'organe de purification et, une partie transfert d'air (6) située dans le passage d'air (2) qui transfère l'air dans le passage d'air (2). La partie transfert d'air (6) est située à l'extérieur de l'espace dans lequel est située la partie aspiration (10).
