| 摘 要： | 运用FDS分析诱导排烟系统的布置方式、机械排烟量、诱导风速等敏感参数对排烟效果的影响,与风管式排烟系统进行比较。结果表明,诱导排烟系统在合理布置的条件下比风管式排烟系统更利于维持车库内的能见度;诱导排烟的能见度随机械排烟量的增加而提高;诱导风机风速受机械排烟能力的限制。

| Abstract: | Numerical simulations have been carried out for investigating the feasibility of the use of impulse ventilation system for smoke control in underground car park.By changing parameters such as arrangement,exhaust rate and impulse velocity,the impact of these parameters on the exhaust effect was analyzed.Ductwork system for smoke control has also been simulated to study the difference between the two exhaust systems.The results have shown that the well designed impulse exhaust system is more capable to keep g... |
