Abstract

Selon un procédé de régulation de la climatisation d'un local dans un bâtiment, une phase d'échange introduisant un volume d'air frais dans au moins un local et évacuant un volume d'air vicié sensiblement de même importance est activée au moyen d'un système de ventilation pouvant être régulé. Le procédé selon l'invention utilise pendant une phase d'échange un débit volumique d'air frais pouvant être prédéfini ainsi qu'un débit volumique d'air vicié équilibrant ce dernier pour un transfert synchrone, si bien qu'une répartition du débit volumique est mise en œuvre par diffusion dans le local. Une unité de mesure d'air est prévue à cet effet et permet de détecter au moins le volume d'air respectivement à l'avant et à l'arrière des locaux, et un équilibre respectif de l'air frais et de l'air vicié permet de régler par diffusion la répartition exempte de différence de pression du débit volumique par rapport à l'environnement concerné du local.
