电动汽车库的消防排烟研究
Fire control and smoke exhaust of electric vehicle garages
摘要：
电动汽车的火灾危险性远大于燃油汽车，因此对电动汽车充电基础设施的火灾防范更需要重视。目前国家、行业还未就电动汽车库的消防、排烟制定出设计规范或技术措施，但已有一些电动汽车消防相关方面的研究。本文在前人研究的基础上，提取了相关数据，选取典型模型，通过计算得出了单个防烟分区火灾时的烟气体积流量，推算出了电动汽车库火灾时单个防烟分区所需的最小排烟量，并在此基础上提出了电动汽车库火灾时可实施的排烟设计方法和技术措施。
Abstract：
The fire risk of electric vehicles is much greater than that of fuel vehicles, so the fire prevention of electric vehicle charging infrastructure needs more attention. At present, the country and the industry have not formulated design specifications or technical measures for the fire control and smoke exhaust of electric vehicle garages, but there have been some studies on electric vehicle fire control. Based on previous researches, this paper extracts the relevant data, selects typical models, calculates the volume flow of smoke during a single smoke compartment fire, deduces the minimum smoke exhaust rate required for a single smoke compartment during an electric vehicle garage fire, and proposes a design method and technical measures for the smoke exhaust that can be implemented during an electric vehicle garage fire.
