空调系统风机选型图的应用

Application of fan selection chart for air-conditioning system

目前空调系统设计人员无法高效地利用风机样本和风机选型软件对风机进行选型。本文以风机在某小型空调箱中的应用为例,提出新的空调风机选型方法。该方法运用计算机绘图软件分析风机性能,绘制风机的能力极限范围,并与设计需求作对比。该方法可以考虑风机在空调系统中的系统效应,操作简单,结果准确。

At present,ai--conditioning system designers cannot effectively select fans using fan catalogue and fan selection software.Taking the application of common fan in a small AHU for example,a new selection method of air-conditioning fan is presented.This method uses graphing software to analyze the fan performance,to map the operating limits of fan and compare with the design demand.This method can take the system effect of the fan in the ai--conditioning system into consideration,its operation is simple and the resutt is accurate.
