摘要： PROBLEM TO BE SOLVED: To provide a fire extinguishing/preventing device and a fire extinguishing/preventing method for preventing quick spread of burning in a compartment fire and efficiently preventing the fire in a short period of time.
SOLUTION: An air compressor 1 takes in air in the atmosphere and compresses the air. The compressed air in the air compressor 1 is fed to a nitrogen separating membrane unit 3 by opening an open/close valve 2. The fed compressed air is separated by the nitrogen separation membrane unit 3 to oxygen-enriched air and NEA (nitrogen-enriched air), and the separated NEA is fed to an NEA nitrogen concentration control device 4. The flow rate of NEA is adjusted by an electromagnetic flow adjusting valve 4a inside the NEA nitrogen concentration control device 4. At the same time, the oxygen concentration in air forced out of the compartment is measured by an outside oxygen sensor 6 and a compartment oxygen concentration measuring device 7, and the measured oxygen concentration is inputted in a flow control box 4b. The flow control box 4b controls the electromagnetic flow adjusting valve 4a based on the inputted value.

摘要翻译：要解决的问题：提供灭火/防火装置以及用于防止火灾中燃烧迅速蔓延并在短时间内有效防止火灾的灭火/防火方法。解决方案：空气压缩机1吸入大气中的空气并压缩空气。空气压缩机1中的压缩空气通过打开/关闭阀2而被供给到氮分离膜单元3.供给的压缩空气被氮分离膜单元3分离成富氧空气和NEA（富氮空气），将分离的NEA供给到NEA氮浓度控制装置4. NEA的流量由NEA氮浓度控制装置4内的电磁流量调节阀4a调节。同时，通过外部氧传感器6和室氧浓度测定装置7测量被迫离开隔间的空气，将测定的氧浓度输入流量控制箱4b。流量控制箱4b根据输入值控制电磁流量调节阀4a。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To inexpensively provide a method and a device for controlling or extinguishing a fire in an uninhabited space with a double-structured roof and walls where there is little possibility of entry of a person.
SOLUTION: The exhaust gas of a fire pump engine 4 with a water tub is used as the fire controlling gas, and the uninhabited space 2, a target region for controlling the fire, is filled with the exhaust gas. The fire is controlled by reducing the oxygen concentration in the uninhabited space 2 to the value or lower at which a flammable object is hard to burn. The fire can be inexpensively controlled by the method and device utilizing the exhaust gas of the fire engine in this way.
