| 摘 要： | 随着城市地下车库的不断修建,地下车库的火灾安全显得尤为重要.目前越来越多的地下车库采用诱导通风系统来控制火灾烟气,为了研究自动喷水作用下诱导通风系统的烟气控制效果,采用火灾模拟软件FDS对地下车库发生火灾时的温度场和开启的喷头个数进行了研究.模拟结果表明采用诱导通风系统,可以使着火车辆上游的烟气大大减少,有利于消防队员从上游进入灭火.同时在诱导通风作用下,喷头启动的个数也大大减少,从而使自动喷水系统能够保持正常工作. |

| Abstract: | As more and more underground car parks are built in the city,it is important to design an good fire protection system.Nowadays,many car parks use the impulse ventilation system to control smoke when fire takes place.In order to study the smoke control of impulses ventilation during car park fires when sprinkler system is installed.The software FDS is used to simulate the smoke temperature and activated sprinkler number during the fire.It is found that with the impulse ventilation,there would be much less smoke upstream the fire,which is favorable for firefighters to put out the fire.Besides there would be much less sprinklers activated with impulse ventilation system,which will help the sprinkler system to works properly. |
