湿空气焓值计算及其对HAT循环分析的影响

Calculation of the Humid Air' Enthapy and Its Influence to the HAT Cycle

以湿空气焓值为研究对象,按理想混合气体模型和实际混合气体模型分别对含湿量恒定条件下空气的焓值进行计算比较。结果表明:在接近饱和的状态下,实际混合气体效应不可忽略,在HAT循环饱和过程参数范围内两者的最大偏差接近7%。因此,HAT循环饱和器分析应按实际混合气体模型计算湿空气的焓值。

The enthalpy of humid air is studied and is calculated by the ideal mixture model and real mixture model respectively, then the calculation results are compared. It shows that the maximum deviation between the two calculation models is near to 7%, the influence of the real gas can not be neglected. So the enthalpy must be calculated by the real mixture model when analyzing the humidifier of HAT cycle. Figs 5 and refs 5.
