A process and a device for atomization of a liquid extinguishing medium, in which the liquid extinguishing medium and a liquid inert gas are mixed in a mixing unit to form a liquid extinguishing medium mixture. The mixture is conveyed through a conduit to a distributing device such as extinguishing nozzles. As the mixture exits the distributing device the mixture is atomized, forming an aerosol spray for extinguishing a fire within an extinguishing area defined by the aerosol spray. A detector arranged in the extinguishing area for detection of parameters relating to extinguishing of the fire is connected to an evaluation device which in turn is connected to a control valve. The control valve regulates the quantity of liquid inert gas supplied to the mixing unit.
L'invention concerne un procédé et un dispositif qui permettent d'obtenir une meilleure atomisation de l'agent d'extinction (eau) et une plus grande portée de jet des gouttes. Pour cela, on ajoute de préférence un gaz inerte liquide sous une pression élevée dans les conduites à l'aide d'un dispositif mélangeur.
