Abstract: The liquid desiccant air handing device, which can be utilized without the restriction of climatic and geographical regions, is one of the most likely air-conditioning technologies to be promoted in large-scale application.In this paper, the single-stage LiCl solution desiccant process of countercurrent packing is studied through experiments.For the desiccant process, influence of the temperature (30-36℃) and relative humidity (50%-70%) of the inlet air on the dehumidification process is investigated.It is resulted that dehumidifying performance is enhanced with the increase of the temperature or relative humidity of the inlet air.In addition, for the solution regeneration process, the effect of inlet temperature of the regeneration air and solution on the regeneration process is studied.It is shown that, the rise of either temperature can increase the regeneration ability, but the effect from the temperature of the regeneration solution is stronger.However, the outlet temperature of the regenerated solution is also increased accordingly, which can lead to a larger amount of cooling load.

摘要： 溶液除湿空气调节装置具有不受气候和地域限制的特点，是最可能被大规模推广的空气调节技术之一。本文进行了逆流填料式单级LiCl溶液除湿过程实验研究，针对除湿过程，研究了进口空气的温度（30～36℃）和相对湿度（50%～70%）对除湿性能的影响。结果表明，除湿性能会随着进口空气温度或相对湿度的升高而增强。此外，针对溶液再生过程，本文考察了再生风进口温度和再生溶液进口温度对再生性能的影响，结果表明，两个温度值的升高均会增大再生能力，且后者的作用更强，但是再生溶液出口温度也会随之上升，从而导致了系统冷源负荷的增大。
