The invention relates to an inerting method as well as an inerting system () to set and/or maintain a reduced oxygen content in an enclosed room (), wherein a gas separation system () is provided which separates off at least a portion of the oxygen from an initial gas mixture provided in a mixing chamber () and by so doing, provides a nitrogen-enriched gas mixture. In order to optimize the operation of the inerting system (), the invention provides for a portion of the air to be withdrawn from the enclosed room () and admixed with fresh air in the mixing chamber ().

Inerting method for preventing and/or extinguishing fire as well as inerting system to realize the method

Described herein are an inerting method as well as an inerting system () for preventing and/or extinguishing fire, wherein a gas separation system () 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 (), 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 () of the gas separation system (). In order to achieve the setting and maintaining of a predefined inerting level with the lowest possible expenditure of energy, the description herein provides for a control device () designed to control the gas separation system () 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 ().
