摘要
依据二元组分混合气体的性质，推导建立了由空气温度、压力和相对湿度表达的湿空气热物理性质的计算方程．为便于工程计算，将这些方程整理成了干空气的热物理性质乘以相应的修正系数．在供暖通风、空调制冷和干燥等技术领域中，使用这些热物理计算方程进行以湿空气为工质的有关传热传质和流动计算，不但精度高，而且使用方便。
Derives equations on the basis of properties of dual gas mixture e for calcuating the den- sity, specific heat capacity at constant pressure, viscosity and thermal conductivity of moist air expressed in terms of air temperature, pressure and relative humidity. For the convenience of engineering calcula- tion, these properties are arranged with the dry air thermophysical properties multiplied by appropriate correction factors, which ensures a satisfactory computational accuracy.
