Abstract

L'invention concerne un dispositif de lutte contre les incendies de forêt à atmosphère sans oxygène et à basse température. Ce dispositif utilise un équipement de refroidissement sans chaleur à transition de phase simple et condense l'air sans oxygène, sur les lieux de l'incendie, tout en tirant profit de l'énergie produite par la différence de température entre le fluide à basse température artificiel et la fumée haute température qui se dégage dans le but de produire une force mécanique. Ce dispositif produit aussi une force aéromotrice et entraîne une circulation thermique à transition de phase sans oxygène de l'air dans les lieux de l'incendie de forêt. Ce dispositif dégage en grande quantité de l'air sans oxygène à basse température et à haute pression qui forme un écran anti-feu et est caractérisé par son faible coût de fabrication, sa sécurité et fiabilité dans la lutte contre les incendies, sa capacité à éteindre des feux de forêt d'une grande envergure ce qui le rend très efficace dans la prévention des retombées économiques et de la pollution environnementale occasionnés par les incendies de forêt.
