地下车库诱导通风辅助排烟系统研究

Study on smoke control system assistant by impulse ventilation in underground garage

总结了传统的管道式排烟模式的局限性以及诱导通风辅助排烟系统的优点。介绍地下车库诱导通风辅助排烟技术的发展,以及国外射流通风排烟系统标准。指出诱导通风辅助排烟技术难点,确定烟气控制参数设定以及车库结构是影响诱导通风辅助排烟的重要问题。总结国内外诱导通风辅助排烟的研究现状。提出加强现场试验和数值模拟从而建立相应的理论体系是未来研究的重点。

The limit of traditional ductwork smoke control system and the advantage of smoke control system assistant by impulse ventilation have been summarized. The development of under- ground garage impulse ventilation system and the standard of jet ventilation and smoke extraction system in other countries were introduced. The technique difficulties in smoke control system assistant by impulse ventilation were pointed out. The key is- sues of this smoke control system are how to determine the smoke control parameters and understand the influence of under- ground garage structure on smoke propagation. Summarized the foreign and native standard related with the impulse ventilation smoke control technology. It was suggested that an important future issue was to establish a theoretical system by strengthe- ning on site test and numerical simulation technology.
