同时，设计了热回收段，热回收效率高，所以这又是一种相当节能的设备。
Meanwhile, the designed heat recovery section, heat recovery efficiency is high, so this is a rather energy-saving equipment.
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.
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).
用热回收装置引进新风后基本没有改变空调器的输入功率，相同环境条件下的制冷量增加，EER值增大，焓差热回收效率最高可达到34.12%。
The input power isn't changed much when the heat recovery device is running, on the contrary the EER value becomes bigger and the enthalpy difference heat recovery efficiency reaches 34.12%.
