摘要:
伴随着各种消防规范的修订、清洁能源的推广以及新能源汽车的逐渐普及，汽车库内停放汽车的种类越来越多，消防水灭火系统的设计遇到不少新的挑战。以南方某城市的Ⅰ类地下汽车库设计为例，介绍了该项目泡沫-水喷淋系统的几个重要设计参数（泡沫液的选择、喷头类型、动作温度、系统流量）的取值方法；分析新形势下地下车库泡沫-水喷淋系统实际运用中需要注意的现实问题（灭火剂保质期短、系统流量经水力计算后较大），对同一个防火分区，规范规定值与水力计算值差距较大，建议实际项目中加入“电算”环节；比较了不同种类汽车对应的灭火方式，建议谨慎选择泡沫-水喷淋灭火系统。
Abstract:
With the revision of various fire codes, promotion of clean energy and gradual popularity of new energy vehicles, more and more kinds of cars parked in the garage, and the design of fire sprinkler system has encountered many new challenges. The selection of several important design parameters (foam concentrate selection, sprinkler type, operating temperature and system flow rate) of a foam?water sprinkler system of a level Ⅰ underground garage in a southern city was analyzed. The practical problems (such as short shelf life of the fire extinguishing agent and large system flow rate after hydraulic calculation) that should be paid attention to in the practical application of the foam?water sprinkler system of the underground garage under the new situation were analyzed. For the same fire compartment, there is a big gap between the specified value in the code and the hydraulic calculation value, so it is suggested to add “electronic calculation” link in the actual project. After comparing the fire extinguishing methods of different types of vehicles, it is suggested to choose the foam?water sprinkler fire extinguishing system carefully.
