| 摘要 |
The invention relates to an inerting method as well as an inerting system (1) for preventing and/or extinguishing fire, wherein a gas separation system (3, 4) is provided to set and/or maintain a predefinable oxygen content, which is reduced compared to normal ambient air, in the spatial atmosphere of an enclosed room (2), said system separating off at least a portion of the oxygen contained in an initial nitrogen/oxygen gas mixture and thereby provide a nitrogenated gas mixture at the outlet (4a) of the gas separation system (3, 4). In order to achieve the setting and maintaining of a predefined inerting level with the lowest possible expenditure of energy, the invention provides for a control device (5) designed to control the gas separation system (3, 4) such that the residual oxygen content of the nitrogenated gas mixture is changed as a function of the oxygen content prevailing at that moment in the spatial atmosphere of the enclosed room (10). |
