示例—蒸汽加湿空气
需要多少蒸汽才能使空气转变30.oF与100%空气湿度70oF与40%湿度?
- 空气30.oF而且100%湿度-蒸汽含量1.67磅/小时(100 cfm /小时空气流)
- 空气70oF而且40%湿度-蒸汽含量2.76磅/小时(100 cfm /小时空气流)
的区别(2.76 - 1.67) =1.09磅/小时需要的蒸汽量是多少100 cfm /小时空气流。
注意!
这张表忽略了所需的显热热冷空气到最终状态。在上面的例子中需要加热的热量100 cfm干燥空气来自30.oF来70oF必须添加。热量可以用加热板或类似的方式作为干热补充,或在一般情况下通过添加更多的蒸汽更方便。
