Abstract

La présente invention se rapporte à un procédé de commande de système de ventilation à récupération de chaleur possédant une fonction de refroidissement par air extérieur. Conformément à la fonction de refroidissement par air extérieur, un mode d'échange thermique et un mode de refroidissement extérieur sont exécutés de manière sélective. En mode d'échange thermique, l'air introduit dans une pièce et l'air refoulé vers l'extérieur s'échangent la chaleur via une section d'échange thermique puis l'air introduit est alimenté à la pièce. En mode de refroidissement par air extérieur, l'air extérieur contourne la section d'échange thermique via un chemin de refroidissement par air extérieur au cas où l'échange thermique ne serait pas nécessaire, afin que l'air soit directement introduit dans la pièce. Conformément à la présente invention, le procédé de commande de système de ventilation à récupération de chaleur possédant une fonction de refroidissement par air extérieur et un dispositif de ventilation a les effets suivants. Premièrement, il est possible d'économiser de l'énergie en ne faisant fonctionner de manière sélective le système de ventilation que lorsque de la pollution d'air ambiant est générée en fonction des informations sur le niveau de pollution d'air ambiant, ou lorsque l'introduction extérieure directe est favorable en termes d'énergie et d'environnement. Deuxièmement, le mode d'échange thermique ou le mode de refroidissement par air extérieur peut être automatiquement exécuté en déterminant un mode favorable en termes d'économie d'énergie en fonction de la disponibilité du refroidissement par air extérieur. Troisièmement, il est possible d'économiser de l'énergie et de maintenir un environnement plaisant en évitant le refroidissement par air extérieur inutile en réduisant une plage définie pour le refroidissement par air extérieur si le niveau de la pollution d'air ambiant est au-dessous des normes de qualité de l'environnement.
