焓湿表的研究及应用
Research and application of psychrometric table
摘要：
将湿空气参数之间的关系式转化为Visual Basic程序代码定义的Excel自定义函数，并在Excel中调用，以简洁的形式计算饱和水蒸气分压力、含湿量、比焓、露点温度、湿球温度，得到焓湿表。使用焓湿表可大幅减小焓湿图法空气处理计算过程中的人工操作误差。

Abstract：
The relationships between the parameters of moist air is transformed to self-defining Excel functions defined by Visual Basic code. Then the saturated water vapour pressure, humidity ratio, specific enthalpy, dew-point temperature, wet-bulb temperature of moist air can be calculated in an Excel table with concise way, and a psychrometric table is obtained. Manual errors in calculating air treatment process using psychrometric chart can be greatly decreased by means of this table.
