摘　　要：本文设计出一种新型太阳能液体除湿系统,在系统中设置回热器,将再生后的浓溶液与未加热前的稀溶液进行热交换,采用闪蒸技术来实现除湿剂在60~70℃下的再生,解决了传统除湿系统中外界环境对再生溶液浓度的影响以及除湿过程耗液量大、系统阻力大的弊端,降低了系统的能耗,使整体效率得到提高。对该除湿装置进行了设计计算和选型,包括太阳能集热器与喷头的选型,再生器、回热器、风冷器的设计计算。A new type of solar liquid desiccant system was designed. A regenerator is set in the system and realize heat exchange between regenerated strong solution with dilute solution of heat transfer before, implement the desiccant regeneration under 60 -70℃ using flash technology. The design overcome the shortcomings of a large amount of consumption liquid and high resistance in the traditional dehumidifica- tion system owing to the effects of external environment on regeneration process, reduced the energy con- sumption of the system so that overall efficiency was improved. The design calculation and equipment se- lection for the dehumidification unit are probed, including the model selection of solar collector and noz- zle, the design calculation of the regenerator, regenerator, air cooling device.
