摘要
除湿器是太阳能液体除湿系统的核心设备,其效率直接影响整个系统的性能。建立叉流液体除湿系统,采用氯化锂为除湿溶液,Celdek填料为热质交换介质,实验测试溶液和空气进出口参数对除湿器焓效率和除湿效率的影响规律,并进行线性回归,结果表明:焓效率主要受溶液流量、空气流量、空气温度及空气含湿量的影响,除湿效率主要受溶液流量和空气流量影响;线性回归方程计算结果和实验结果吻合较好。
Dehumidifier is the core component in a liquid desiccant air-conditioning system driven by solar energy, which efficiency directly affects the whole performance. In this study a cross-flow dehumidifier was established in which LiC1 solution and Celdek structured packing were used. Influence of desiccant and air inlet parameters on the dehumidifier performance was experimentally investigated. The results showed that enthalpy efficiency is mainly affected by the solution flow, air flow, air temperature and moisture content; dehumidification efficiency is mainly decided by solution flow and air flow ; the calculated results of linear regression equation agree well with experimental ones.
