摘　　要：分析了合用前室机械防烟系统存在的问题。针对设有机械防烟系统的合用前室,通过改变加压送风量及送风口位置研究合用前室开门工况条件下的防烟情况,分析影响合用前室防烟效果的原因。结果表明,加压送风量越大,送风口位置越靠上,防烟效果越好。为机械防烟系统的设计提供理论参考。Problems of common antechamber mechanical smoke extraction system were analyzed. By changing the pressurized air supply and air outlet location, the smoke control effect of common antechamber open condition was studied, and the rea- sons influencing common antechamber mechanical smoke ex- traction system were analyzed. Results showed that the bigger the pressurized air supply volume, the higher the air outlet lo- cation, the better the smoke controlling effect. The research can provide reference for mechanical smoke extraction system design.
