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60m3／h計算，擔負多個防煙分區則按平方米面積不小于120m3／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，排煙量一般根據大防煙分區面積500*120等于60000立方每小時計算，在通風管道設計排煙量的時候要注意漏風量，一般可按小漏風量10%計算。例如：當建筑面積為1000平方時，通風管道批發需要設置兩個防煙(yan)分區(qu)，每個防煙(yan)分區(qu)的大面(mian)積(ji)為(wei)500平方，排(pai)煙(yan)量(liang)是500*1203／h=600003／h，再加上小漏風量(liang)10%為(wei)60003／h，總排(pai)煙(yan)量(liang)應為(wei)660003／h，其中送風量(liang)為(wei)排(pai)煙(yan)量(liang)的50%應為(wei)330003／h。
