摘　　要：随着我国新能源汽车保有量逐年上升,动力电池汽车起火事件也随之增多,原有自动喷水灭火系统对此灭火效果不佳。选取高压细水雾作为动力电池汽车灭火剂进行研究,对高压细水雾自身特性及灭火特点进行概述,并详细探讨了如何在室内外充电停车库中设计高压细水雾系统。由于现行规范的限制,将开式系统与局部应用系统相结合,控制干式管网的长度在300 m内,则整个地下车库可仅设置一套泵组;在局部应用系统中,通过加大喷雾强度至3.04 L/(min·m^(2))以保证灭火效果;为提升系统应急响应速度,采用新型红外温度传感器、车辆自带电池组温控系统联动启动高压细水雾系统。该系统灭火效果较好,可以为类似项目提供参考。With the annual increase in the number of new energy vehicles in China,fire incidents involving power battery vehicles continues to rise.The existing automatic sprinkler system demonstrates inadequate firefighting effectiveness.In view of this,high‑pressure water mist was selected as the fire extinguishing medium for power battery vehicles.This paper summarized the characteristics and fire extinguishing capability of high‑pressure water mist,and provided an in‑depth discussion on the design for implementing high‑pressure water mist systems in both indoor and outdoor electric vehicle charging parking garages.Given the constraints imposed by the current code,the open system was integrated with the localized application system,and the length of the dry pipe network was restricted to within 300 m.Consequently,only a single set of pumps was installed throughout the entire underground garage.In the localized application system,the efficacy of fire extinguishing was ensured by augmenting the spray intensity to 3.04 L/(min·m^(2)).To enhance the system’s emergency response speed,the new infrared temperature sensors and the vehicle battery pack’s temperature control system were employed to activate the high‑pressure water mist fire extinguishing system.The system has a good fire extinguishing effect,and can provide reference for similar projects.
