摘　　要：再生器是溶液除湿系统中的关键部件之一,提高再生器综合性能是解决极端热湿气候区高湿问题的有效手段。将指标相关法(CRITIC,Criteria Importance Through Intercriteria Correlation)和优劣解距离法(TOPSIS,Technique for Order Preference by Similarity to Ideal Solution)联合,建立CRITIC-TOPSIS模型,用于再生器运行入口参数(空气质量流量、溶液质量流量、温度)的选择评价。以永暑岛礁地区为例,通过再生器处理模型得到基础数据以及4个指标的评价体系,采用CRITIC法求得权重后使用TOPSIS法对220种运行入口参数的组合方案进行评价得到最优解。结果表明,空气质量流量为0.1 kg/s、溶液质量流量为0.3 kg/s、溶液温度为56℃时得分0.885,为永暑地区再生器综合性能最优解;再生量指标的权重为0.4,可作为永暑地区再生器综合性能的代表性指标。High humidity is one of the typical climatic characteristics in extreme hot and humid climate regions.Generally,extreme hot and humid climate regions are mostly found in low latitude island and reef areas.Influenced by geographical and meteorological factors,buildings in these regions often have high indoor humidity levels and a high risk of condensation,requiring high moisture resistance performance for the building envelope.However,with the use of appropriate dehumidification systems,effective control can be achieved to improve the indoor humidity environment of buildings.Compared to other dehumidification methods such as condensation dehumidification and rotary dehumidification,solution dehumidification systems have a higher utilization rate of low-temperature waste heat,easier control of air operating parameters,and lower requirements for the quality of high-temperature cold sources.Additionally,in extreme hot and humid climate zones,natural energy sources such as solar energy and wind energy are abundant.Therefore,solution dehumidification systems have great development potential in extreme hot and humid climate regions.Regenerator is one of the key components in the solution dehumidification system,and its performance improvement is important for solving the problem of high humidity in extreme hot and humid climate zones.The CRITIC-TOPSIS model is jointly established by the Criteria Importance Through Intercriteria Correlation(CRITIC) and the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) for evaluating the selection of inlet parameters for regenerator operation,including air mass flow rate,solution mass flow rate,and solution temperature.Taking the Yongshu island as an example,by building a regenerator processing model and collecting basic data,we constructed an evaluation system that includes four indicators.These indicators are regeneration volume,wet efficiency,temperature efficiency and enthalpy efficiency.The TOPSIS method is utilized to evaluate the combination of 220 operatio
