摘要

在太阳能溶液再生系统实验平台上

以LiCl水溶液作为再生盐溶液

对太阳能溶液再生过程进行了实验研究

获得了系统重要运行参数对太阳能溶液再生性能的影响。结果显示:空气和溶液质量流量的增加对系统性能的影响相对较大

再生量分别增加了7倍和51.46%。较高的溶液进口温度能够提高再生量及太阳能溶液再生系统能量利用率

但是溶液温度过高会降低系统能量利用率以及增加系统输入的能量大小

溶液浓度的增加不利于再生量的提高

并会降低太阳能集热器集热效率和系统能量利用率

太阳辐射值的增加可以提高集热器集热效率

但会降低系统能量利用率。为后续如何在溶液再生过程中充分利用太阳能以及优化太阳能溶液再生性能提供了实验依据。

Abstract

To investigate the performance of solar liquid desiccant regeneration

experiments in the system of the solar liquid desiccant regeneration using LiCl solution as the liquid desiccant were performed. The effects of the important operating parameters on the performance of the system were analyzed experimentally. The results showed that

the air and solution mass flow rate had a big positive impact on the performance of the system. The regenerated rate and the energy utilization rate of the system were increased with the liquid desiccant regeneration temperature

but the heat collecting efficiency was decreased with the liquid desiccant regeneration temperature. The regenerated rate

the heat collecting efficiency and the energy utilization rate of the system would be reduced if the solution concentration increased. And the heat collecting efficiency increased when the solar radiation increased

the system energy utilization rate reduced on the other hand. In addition

the experimental results provided reliable data for the further analysis about how to make use of solar energy efficiently on solution regeneration process.
