T/JFPA 0015-2024 Acoustic low-pressure fine water mist fire-extinguishing system technical specification

Scope

Scope: 1.1 This standard applies to dual-fluid fine water mist fire suppression systems with a nozzle working pressure of 0.35MPa to 1.2MPa, and nitrogen and water as fire suppression media. 1.2 This standard applies to the design, construction, acceptance, and maintenance management of acoustic low-pressure fine water mist fire suppression systems installed in construction projects. 1.3 This standard applies to the design, construction, acceptance, and maintenance management of acoustic low-pressure fine water mist fire suppression systems installed in mobile equipment, vehicles, ships, and aircraft cargo compartments. 1.4 This standard applies to the design, construction, acceptance, and maintenance management of acoustic low-pressure fine water mist fire suppression systems installed in electrochemical modules. 1.5 Acoustic low-pressure fine water mist fire suppression systems are suitable for extinguishing fires in relatively enclosed spaces involving combustible solid surfaces, combustible liquids, and live electrical equipment, as well as for providing inerting and cooling/dust suppression in protected areas. Main technical content: Acoustic low-pressure fine water mist fire suppression systems are dual-fluid low-pressure fine water mist fire suppression, fire control, and fire prevention systems using water and nitrogen as fire suppression media. The fundamental difference between acoustic low-pressure fine water mist fire suppression systems and other fine water mist systems lies in the different mechanisms of generating fine water mist. Nitrogen generates certain acoustic waves at the nozzle, and when water passes through the nozzle, it is rapidly atomized and sprayed into the protected area. Upon encountering flames, the water instantly vaporizes, creating a high-efficiency oxygen-depleted environment. Through the cooling and suffocating effects of water vapor and nitrogen, the fire can be rapidly suppressed and extinguished. Under the mi
