Abstract

L'invention concerne des échangeurs thermiques d'air frais qui fonctionnent pour apporter une ventilation, un chauffage et une purification de l'air. Le dispositif le fait que le bâtiment soit occupé ou vide. L'air extérieur est aspiré vers l'intérieur, filtré, puis passé à travers l'échangeur thermique où l'air de la pièce est passé près de lui et sa chaleur est extraite et transférée à l'air frais entrant. L'air de la pièce est par la suite évacué à l'extérieur. L'air extérieur frais préchauffé continue vers un serpentin d'eau chaude où il est en outre chauffé, puis passé sur une cellule UV en vue de la purification. L'air chauffé purifié est introduit dans la pièce. Dans la phase inoccupée du bâtiment, l'air de la pièce est recyclé dans la pièce sans faire entrer l'air frais.
