摘要
针对《高规》中，对于前室或合用前室加压送风口开启控制方式没有明确规定这一问题，采用压差法和流速法计算典型前宣的加压送风量，证明规范给定的风量宜用于设置常开型风口的加压送风系统。
For ＂Code for fire protection design of tall building＂, the way to control pressurization air outlet in antechamber that issue has not clearly defined. The methods of positive pressure and critical air velocity are used to compute the air flow of typical antechamber, to prove to the air flow set by the code should be used to set up pressurization air outlet（NC） system.
