通风机及其系统在不同海拔高度的性能变化及运用分析

Performance and application analysis of fan and its system in different altitude

一种通风机在设计和制造后,一般只在特定的海拔下进行性能的测定,而实际上其可能会在不同海拔运行。文章分析了通风机处在不同海拔高度时性能的变化,建立了不同海拔高度性能计算模型,并综合分析了通风机及系统在不同海拔时的运用情况。案例分析验证了所提出的模型和方法的可行性和有效性。

We will measure fan＇s performance in customizing altitude after it was design and manufactured, but the fan will run in different altitude actually.This paper analyzed the change of performance, builded the calculate model, and analyzed the application in different altitude.A case shows that the model is practical.
