Abstract

Dans la présente invention, de l'air intérieur est de préférence purifié, avant qu'un mode de commande d'enthalpie soit vérifié, en actionnant une unité de filtre de ventilateur en fonction de la concentration de poussière de l'air intérieur, et ainsi la poussière intérieure est efficacement éliminée. En conséquence, la présente invention présente un avantage en ce qu'un environnement optimal pour la production d'une plante utilisée pour la fabrication d'un produit pharmaceutique peut être maintenu. De plus, dans le cas où il est déterminé que l'air intérieur n'est pas suffisamment purifié lorsque la concentration de poussière est re-détectée après que l'unité de filtre de ventilateur a fonctionné pendant un temps prédéterminé, de l'air extérieur est introduit pour une ventilation, et la proportion de l'air extérieur introduit est régulée de manière variée en fonction de la différence de température entre l'air intérieur et l'air extérieur, de telle sorte que l'environnement intérieur peut être commandé de manière optimale tandis que l'air intérieur est purifié. En outre, étant donné que l'introduction de l'air extérieur est commandée sur la base d'une différence d'enthalpie entre l'air intérieur et l'air extérieur après que l'air intérieur soit suffisamment purifié au moyen de l'unité de filtre de ventilateur, l'air extérieur peut être introduit de manière appropriée, et la consommation d'énergie peut être réduite par l'intermédiaire d'un processus de refroidissement d'air à l'aide de l'air extérieur.
