1. Inerting method in which an oxygen content which is predefinable and reduced in comparison to normal ambient air is set and maintained in the spatial atmosphere of an enclosed room, wherein the method comprises the following procedural steps:
i) providing an initial gas mixture of oxygen, nitrogen and further elements as applicable; ii) compressing the initial gas mixture provided in a compressor system; iii) feeding the compressed initial gas mixture to a gas separation system and separating at least a portion of the oxygen contained in the compressed initial gas mixture so as to provide a nitrogen-enriched gas mixture at the outlet of the gas separation system; and iv) introducing at least part of the nitrogen-enriched gas mixture provided at the outlet of the gas separation system into the spatial atmosphere of the enclosed room so as to set and/or maintain an oxygen content in the spatial atmosphere of the enclosed room which is predefinable and reduced in comparison to normal ambient air, wherein when an amount of nitrogen-enriched gas mixture provided per unit of time at the outlet of the gas separation system needs to be increased, the degree of compression realized in method step ii) is increased, particularly to a value dependent on the amount of nitrogen-enriched gas mixture to be provided per unit of time, wherein to supply the initial gas mixture in method step i), a portion of the ambient air within the enclosed room is extracted from the room in regulated manner and fresh air is fed in regulated manner to the extracted portion of the room air, wherein an amount of fresh air to be added to the ambient air extracted from the room is selected such that the amount of ambient air extracted from the room per unit of time is identical to the amount of the nitrogen-enriched gas mixture introduced into the spatial atmosphere of the room in method step iv). |
