Abstract

Un objet de l'invention permettant d'atteindre ce but est un système de ventilation d'un local comprenant : - un circuit principal apte à véhiculer un flux principal de gaz, comprenant un moyen pour générer une différence de pression entre un premier point dudit circuit principal à une première pression et un second point dudit circuit principal à une seconde pression, la seconde pression étant supérieure à la première pression ; - un circuit dérivé apte à véhiculer un flux dérivé de gaz, et comprenant : • un détecteur ; • un moyen de refroidissement du flux dérivé de gaz disposé de manière à refroidir ledit gaz en amont du détecteur ; ledit circuit dérivé étant disposé en dérivation du circuit principal, et étant relié au premier point et au second point, de manière ce que le flux dérivé de gaz circule depuis ledit second point vers ledit premier point.
