通过一系列实验，研究了热湿交换材料特性、通道长度和运行工况等因素对全热交换器热回收效率的影响。

Through a series of experiments, studies the influence of material properties, passage dimensions and operating conditions on the cross-flow heat recovery ventilator (CFHRV).

但是如今国内生产的全热交换器，大部分都是叉流形式的，热回收效率难以得到提高。

But now the domestic heat exchange ventilators, most of which are forms of cross-flow, and their heat recovery effectiveness can hardly be improved.
