摘　　要：对高层民用建筑防排烟的加压部位进行了优选,确定前室或合用前室为最佳加压部位。对机械加压送风防烟设施与自然排烟防烟设施进行了甄选,认为应淘汰自然排烟防烟设施,采用机械加压送风防烟设施。建议由最佳加压部位(即前室或合用前室)和机械加压送风防烟设施组成只向前室或合用前室加压的机械加压送风防烟系统。Determines that the antechamber or common antechamber should be taken as the best pressurization part in high rise building smoke control and extraction through optimization. Compares the mechanical pressurization smoke prevention facility and the natural smoke extraction and prevention facility, and considers that the former is better. With the best pressurization part--antechamber or common antechamber, and the mechanical pressurization smoke prevention facility, forms a mechanical pressurization smoke prevention system which only pressurizes the antechamber or common antechamber.
