Experiment on fresh air equipment based on indirect water-evaporating cooling

针对室内排风的热回收效率不高的问题,设计了一种基于间接蒸发冷却技术的新回风换气机,采取微雾喷淋方式的水蒸发冷却技术和亲水高分子纤维的芯体,可实现高效热回收。通过建立实验平台,对该新风换气机的换热过程进行了测试分析,结果表明热回收效率高达141%,节能效果显著。

In order to solve the problem of low heat recovery efficiency of indoor exhaust air,a new return air ventilator based on indirect evaporative cooling technology was designed.The water evaporative cooling technology with micro-mist spraying and the core of hydrophilic polymer fiber can realize high efficiency heat recovery.The heat transfer process of the new heat exchanger was tested and analyzed by establishing an experimental platform.Results show that the heat recovery efficiency is up to 141%,and the energy-saving effect is remarkable.
