Abstract

La présente invention concerne un purificateur d'air de type ventilation. Un purificateur d'air de type ventilation selon un mode de réalisation donné à titre d'exemple de la présente invention comprend : un logement ayant un espace interne et ayant un orifice d'aspiration d'air intérieur, un orifice d'évacuation d'air intérieur, un orifice d'aspiration d'air extérieur et un orifice d'évacuation d'air extérieur, qui permettent la communication avec l'espace interne ; une première soufflante d'air disposée dans l'espace interne de telle sorte que l'air extérieur s'écoule dans l'espace interne et l'air extérieur ayant circulé dans l'espace interne peut être évacué dans une pièce ; une seconde soufflante disposée dans l'espace interne de telle sorte que l'air intérieur s'écoule dans l'espace interne et l'air intérieur ayant circulé dans l'espace interne peut être évacué vers l'extérieur ; un échangeur de chaleur pour permettre un échange de chaleur entre l'air extérieur ayant circulé dans l'espace interne à travers la première soufflante et l'air intérieur ayant circulé dans l'espace interne à travers la seconde soufflante ; et un élément de filtre permettant de filtrer l'air extérieur s'écoulant dans l'espace interne à travers l'orifice d'aspiration d'air extérieur.
