INERTING METHOD FOR PREVENTING AND/OR EXTINGUISHING FIRE AS WELL AS INERTING SYSTEM TO REALIZE THE METHOD

摘要

The invention relates to an inerting method as well as an inerting system (1)forpreventing and/or extinguishing fire, wherein a gas separation system (3, 4)is providedto set and/or maintain a predefinable oxygen content, which is reducedcompared tonormal ambient air, in the spatial atmosphere of an enclosed room (2), saidsystemseparating off at least a portion of the oxygen contained in an initialnitrogen/oxygengas mixture and thereby provide a nitrogenated gas mixture at the outlet (4a)of the gasseparation system (3, 4). In order to achieve the setting and maintaining of apredefinedinerting level with the lowest possible expenditure of energy, the inventionprovides fora control device (5) designed to control the gas separation system (3, 4) suchthat theresidual oxygen content of the nitrogenated gas mixture is changed as afunction of theoxygen content prevailing at that moment in the spatial atmosphere of theenclosedroom (10).
