FIELD: fire-extinguishing means.
SUBSTANCE: invention relates to method and device for regulated feeding of supply air into constantly inertised room with specified level of inertisation, which is regulated or must be regulated and supported within specified range of regulation, and provides possibility of supporting specified range of air regeneration in constantly inertised room and constant efficient prevention if ignition risk in the room by the most efficient and economical way. For this purpose with volume expenditure (VN2), with which inert gas is supplied into the room atmosphere, value, sufficient for supporting specified inertisation level in the room atmosphere, is connected. In addition, into the room atmosphere fed is exactly the same amount of fresh air, which is directly necessary for removal from said atmosphere of that part of pollutants, which was not removed via corresponding outlet system of outgoing air by supplying inert gas.
EFFECT: method provides possibility of supporting specified level of air regeneration in constantly inertised room and constant efficient prevention of ignition risk in room in the most efficient and economical way.
