　　针对全热交换器传湿效果不明显的特点，提出了以带孔纸为支撑层，涂敷亲水膜的方式提高交换膜的热效率。基于所采用的交换膜，实验测量了多孔纸膜的热质交换性能；同时，建立了有限元数值仿真模型，研究了不同孔径、孔间距对全热交换器换热效果的影响。结果表明：对于全热交换器而言，采用敷膜多孔纸的方式，可以有效提高全热交换器的换热效率，实验结果与数值模拟结果相符。在带孔纸能够起到支撑层作用的前提下，孔密度越大越好，结合实际加工工艺特点，多孔纸膜中孔的直径应该控制在1 mm左右。为全热交换膜段优化设计提供了热设计参考数据。

A new type of total heat exchange membrane was proposed for improving heat exchange efficiency. The membrane was based on porous paper as supporting layer coating with hydrophilic film. The thermal and mass transfer efficiency were measured with the membrane proposed. And also, a finite element model was established with different hole diameter and hole spacing. The finite element simulation results agree well with the experiment results, which show that heat exchange efficiency of the membrane proposed in the present work was a massive improvement. The optimum value of the hole diameter should around 1 mm. On the premise that porous paper works well as supporting layer, the bigger of the hole density (the area percent of holes in the paper), the better of the heat exchange efficiency.
