摘要

溶液除湿空调系统在去除潜热负荷上的优越性使得该技术成为制冷空调领域的研究热点

针对系统中除湿/再生器部件进行研究

设计并制作一种新型Z型填料(比表面积160 m2·m-3)

与相同体积形状的蒙特波纹填料(比表面积450 m2·m-3)进行再生性能对比实验。实验结果表明:Z型填料的再生量约为规整填料的40%左右

再生效率约为规整填料的50%左右

再生热效率约为规整填料的70%

且可将Z型结构间距缩小以增大比表面积

各性能指标均有较大提升空间

提高再生性能

可望达到替代规整填料的性能要求。

Abstract

Liquid desiccant air conditioning systems have become popular because of the advantage in removal of latent heat load. Regeneration performance is experimentally studied on a liquid regenerator filled with novel Z-type packing (specific surface area 160 m2·m-3) and corrugated structured packing (specific surface area 450 m2·m-3).The results show that

under the same operating condition in winter

the regeneration rate

the regeneration efficiency and the regeneration thermal efficiency of Z-type packing are about 40%

50% and 70% of the corrugated structured packing respectively. In addition

all the regeneration performance indicators have large space to improve through reducing the space between Z-type units. The Z-type packing in liquid desiccant regenerator is promising compared with the corrugated structured packing.
