Abstract

L'invention concerne un système et un procédé de purification d'air intérieur. Le système de purification d'air intérieur (1000) comprend au moins deux canaux d'écoulement d'air (1100) faisant communiquer l'intérieur (2) d'une pièce avec l'extérieur (1) de la pièce, et des dispositifs de champ électrique, les au moins deux canaux d'écoulement d'air (1100) étant respectivement disposés sur au moins deux cloisons (1200) qui séparent l'intérieur de la pièce de l'extérieur de la pièce, et chaque canal d'écoulement d'air (1100) étant équipé à l'intérieur du dispositif de champ électrique pour la purification de l'air ; et l'air de l'extérieur (1) de la pièce pénètre dans l'intérieur (2) de la pièce à partir d'au moins un canal d'écoulement d'air (1100) sur au moins une cloison (1200), et l'air de l'intérieur (2) de la pièce étant évacué vers l'extérieur (1) de la pièce à partir d'au moins un canal d'écoulement d'air (1100) sur l'autre cloison (1200). S'il y a du vent à l'extérieur (1) de la pièce, l'air à l'extérieur (1) de la pièce est soumis, sans nécessiter d'autre énergie et uniquement en fonction de la convection de l'air, à une purification via les canaux d'écoulement de l'air (1100) et pénètre ensuite à l'intérieur (2) de la pièce, et l'air à l'intérieur (2) de la pièce est évacué vers l'extérieur (1) de la pièce via les canaux d'écoulement de l'air, également sans nécessiter d'autre énergie.
