中文摘要：

设计了一种具有多效回热可用于太阳能液体除湿空调系统的溶液再生器，用碘钨灯作为模拟太阳光源对系统进行了稳态实验，得到出口浓度与光辐射强度、溶液流量、强迫对流风速和入口溶液浓度的关系曲线，给出了系统性能系数与太阳光强度的关系，并对装置的传热传质关系作了简化计算，对影响系统性能的其他因素也进行了分析，实验结果表明，由于系统采用了多效回热措施，系统的回热率相对太阳辐射能来说达到32％。由实验结果估计，在晴好天气条件下，该系统每天每平方米集热器可处理LiBr溶液量（47％～52％）约86kg。

英文摘要：

A multi-effect regeneration solution regenerator which can be used in solar desiccant air-conditioning system was constructed. The steady state experiments were carried out with the iodine-tungsten lamp as the light source. The curves about the density variation of the outlet solution versus the light radiation intensity, the flow rate of solution, the speed of the forced-flow wind and the density of the inlet solution, respectively were obtained and the heat and mass transfer were calculated. The other factors affect the system performance were also discussed. The results of the test showed that the regeneration rate versus the solar radiation is about 32% because of the application of multi-effective re- generation. It can be estimated that the system can deal with the LiBr solution （the density： 47% - 52%） 86kg each day per square meter of collector under the sunny day.
