      摘要:

      電動汽車的火災危險性遠大于燃油汽車,因此對電動汽車充電基礎設施的火災防范更需要重視。目前國家、行業還未就電動汽車庫的消防、排煙制定出設計規范或技術措施,但已有一些電動汽車消防相關方面的研究。本文在前人研究的基礎上,提取了相關數據,選取典型模型,通過計算得出了單個防煙分區火災時的煙氣體積流量,推算出了電動汽車庫火災時單個防煙分區所需的最小排煙量,并在此基礎上提出了電動汽車庫火災時可實施的排煙設計方法和技術措施。

      關鍵詞:電動汽車火災;充電基礎設施;起火狀態;熱釋放速率;排煙量;地下車庫;消防排煙

      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.
