前室独立加压送风系统设计的探讨

Discussion on Pressurizing Air Individual Supply System in Antechamber

从技术应用角度,根据现行有关防火规范,探讨前室单独加压送风系统设计时的有关问题。根据常开型风口与常闭型风口系统的特点,指出压差法和风速法计算风量时应注意的问题,并分析加压送风口的适宜设计风速,提出个人观点,与同行共同探讨。

From the view of applied technical issues and present fire protection and prevention rules, several questions about pressurizing air individual supply system in antechamber were discussed in detail. According to the characteristic of opens air inlet and close air inlet systems, the difference between the calculations of air volume on the pressure difference and air velocity was pointed out, and a suitable design air velocity for pressurizing air was put forward.
