湿表面换热器的线性理论和简化计算方法

湿表面传热的数学描述和求解比干表面要复杂得多，但在应用了线性饱和线的简化理论，并引入了温表面温度、湿态放热系数和湿态比热等概念后，得到了与于表面换热器微分方程类似的形式，从而看出完全可以用干表面换热器的计算方法近似计算湿表面换热器的传热性能。

A SIMPLIFIED CALCULATION METHOD ABOUT HEAT EXCHANGER OF WET SURFACE

A simplified calculating method about heat exchanging ability of wet surface heat exchanger is proposed. Using the linear simplified theory of saturation line, the equations of Wet surface heat exchanging are derived. Import the conceptions, such as wet surface temperature,Wet-state heat exchanging code and wet-specific heat, obtain the equations which just like the equations of the dry surface heat exchanger. Therefore, we can use the calculation method of dry surface heat exchanger to calculate the heat exchanging ability of the wet surface appraximately.
