  • the saturated water vapor amount may be treated as a constant.
  • the saturated water vapor amounts m10, m20, and m30 are treated as saturated water vapor amounts at a predetermined temperature, that is, constants.

Abstract

L'invention concerne un dispositif de commande de ventilation (1) permettant d'augmenter la durée de ventilation et de supprimer la quantité de polluants atmosphérique entrants, ledit dispositif de commande de ventilation étant équipé d'une unité d'acquisition d'informations de température (11), d'une unité d'acquisition d'informations de qualité d'air (12), d'une unité de commande (13), d'une première unité de calcul (14), d'une seconde unité de calcul (15) et d'un comparateur (16). L'unité d'acquisition d'informations de température (11) acquiert des informations concernant la température intérieure et la température extérieure, et l'unité d'acquisition d'informations de qualité d'air (12) acquiert des informations concernant la concentration de polluants atmosphériques. La première unité de calcul (14) calcule la quantité d'admission d'air (une première quantité d'admission) par unité de temps, et la seconde unité de calcul (15) calcule la quantité d'admission de polluants atmosphériques (une seconde quantité d'admission) par unité de temps. L'unité de comparaison (16) compare la seconde quantité d'admission à une valeur seuil. Lorsque la seconde quantité d'admission est inférieure à la valeur seuil, l'unité de commande (13) maintient l'état de ventilation d'un élément de ventilation (2), et lorsque la seconde quantité d'admission est égale ou supérieure à la valeur seuil, l'unité de commande place l'élément de ventilation (2) dans un état d'arrêt de ventilation.
