Ain (01) - Devis ventilation double flux - ventilation double flux prix - ventilation double flux piece par piece - vmc double flux renovation

La ventilation mécanique de type « double flux » est conçue pour renouveler l’air dans le bâtiment et en même temps récupérer les calories contenues dans cet air. L'air intérieur est aspiré par la ventilation double flux dans les pièces humides (cuisines, salles de bains) et passe dans un échangeur à plaques où il transmet ses calories à l'air entrant venant de l'extérieur avant d'être rejeté. L'air entrant réchauffé par l'air extrait est envoyé grâce à la vmc double flux vers les pièces sèches. Le rendement peut atteindre 96%.
