三种太阳能液体除湿空调系统除湿器的比较

太阳能液体除湿空调的除温器是系统的重要组成部分。文章通过对三种典型结构的除湿器的传热传质性能、被处理空气与除湿溶液的质量流量比率（MR）和蓄能能力（SC）等方面的比较，得出绝热型除湿器具有比表面积大，被处理的空气流量大等优点，但加湿器内沿程压降较大；水冷型除湿器蓄能能力强，但结构复杂；而交叉流型板式除湿器由于能充分利用回风，是一种可供选择的节能型除湿器。

Comparison of three kinds of dehumidifier for solar air conditioning with liquid desiccants

The dehumidifier for solar air conditioning with liquid desiccants is an important part in the system. By comparison of heat and mass transfer, the mass ratio of air to desiccant solution and storage capacity of three typical dehumidifiers, it is concluded that the adiabatic dehumidifier has the advantages of large heat transfer area per volume and large air volume, however, the disadvantages of a high pressure drop through the adiabatic dehumidifier is acknowledged; the water cooled dehumidifier can achieve efficient energy storage, but its structure is complex and the cross-flow type plate dehumidifier is a economical dehumidifier for the full use of the return air.
