Application of ambient-temperature, atmospheric-pressure perfluorohexanone jet extinguishing device in electrochemical energy storage equipment
Perfluorohexanone (perfluoro-2-methyl-3-pentanone) fire extinguishing agent, at room temperature for the colorless, odorless transparent liquid, boiling point of about 49 ℃, latent heat of evaporation of water 1/25, very easy to vaporize. It has high extinguishing efficiency (comparable with Halon-1301), inactive on ozone (ODP=0), greenhouse effect index (GWP) is only 1, NOAEL is 10%, good insulation properties and so on. Perfluorohexanone fire extinguishing agent has been used in Europe and the United States and other developed countries for more than 20 years of history, and is included in the standard of the National Fire Protection Association (NFPA2001 version) as a clean gas fire extinguishing agent. Due to the superior performance of perfluorohexanone fire extinguishing agent, such as easy transportation, good compatibility, cleanliness and environmental protection, high extinguishing efficiency, low toxicity, etc., it is considered to be the most promising fire extinguishing agent to replace halogenated alkanes such as sevofluoropropane and trifluoromethane and other transitional halon extinguishing agents.
