Abstract:
A system for suppressing a fire in an enclosed space, comprising:at least one nitrogen supply device selected from the group consisting of compressed nitrogen gas storage tanks and nitrogen gas generators, adapted to supply a first flow of nitrogen gas; a nitrogen preparation unit adapted to supply a second flow of nitrogen gas, at a lower maximum flow rate and for a longer maximum duration than said first flow of nitrogen gas supplied by said at least one nitrogen supply device; at least one nozzle that is arranged in the enclosed space and that is adapted to emit nitrogen gas from said nozzle into the enclosed space; a pipe arrangement connecting said at least one nitrogen supply device and said nitrogen preparation unit to said at least one nozzle; a flow rate limiting device interposed in said pipe arrangement with said at least one nozzle located on an outlet side of said flow rate limiting device and with said at least one nitrogen supply device and said nitrogen preparation unit located on an inlet side of said flow rate limiting device; and a pressure reservoir interposed in said pipe arrangement and connected to said flow rate limiting device upstream on said inlet side thereof.
