摘要(Abstract)：

从理论上分析了溶液除湿过程中传质过程和传热过程之间的耦合关系,建立了相应的数学模型,并对实际的溶液除湿过程进行了数值模拟。结果表明:传质过程对传热过程的影响主要体现在两方面:一是传质通量携带的焓对传热过程的影响,二是水蒸气变成水释放汽化潜热对传热过程的影响,其中汽化潜热的影响较大。而传热过程对传质过程的影响主要体现在温度对传质系数的影响。
Coupling relationship between the mass transfer process and heat transfer processes in liquid desiccant dehumidification process is analyzed theoretically,the physical and mathematical model is developed,and simulates the actual liquid desiccant dehumidification process. The result shows that: the influence of mass transfer process to the heat transfer process is mainly embodied in two aspects: first,the enthalpy carried by the mass flux impact on the heat transfer process,the second is the water vapor turns into water release of latent heat of vaporization influence on the heat transfer process,between them,the latent heat of vaporization is affects obviously. The influence of heat transfer process to the mass transfer process is mainly embodied in temperature.
