PF-200/300/400/500排氣扇 衛生間通風器的詳細資料

PF-200/300/400/500排氣扇  衛生(sheng)間通風器防排煙風機風量與送風機風量如何計算消防排煙風機風量與送風機風量計算方法是根據建筑面積來確定的，每個防煙分區都需要獨立計算其排煙量，當排煙風機擔負一個防煙分區的時候可按平方米面積不小于60m／h計算，擔負多個防煙分區則按平方米面積不小于120m／h計算。送風量按排煙量的50%計算。每個防煙分區不應大于500平方。常見的消防防排煙系統中，排煙量一般根據zui大防煙分區面積500*120等于60000立方每小時計算，在設計排煙量的時候要注意漏風量，一般可按zui小漏風量10%計算。例如：當建筑面積為1000平方時，需要設置兩個防煙分區，PF-200/300/400/500排(pai)氣扇  衛生間通風器每個防煙分區的zui大面積(ji)為(wei)(wei)500平方，排煙量(liang)(liang)是500*120／h=60000／h，再(zai)加上(shang)zui小漏風(feng)量(liang)(liang)10%為(wei)(wei)6000／h，總排煙量(liang)(liang)應為(wei)(wei)66000／h，其中送風(feng)量(liang)(liang)為(wei)(wei)排煙量(liang)(liang)的50%應為(wei)(wei)33000／h。
