摘　　要：建立太阳能驱动的中空纤维膜液体除湿系统的[火用]分析模型,对系统各部件进行[火用]分析,分析空气、冷水进口参数和溶液流量对系统性能的影响。结果显示:1)影响系统[火用]效率较大的因素是空气进口含湿量、空气流量、冷水温度和冷水流量;2)整个系统中太阳能集热器部件的[火用]损最大,可见提高太阳能集热器的性能是提高系统[火用]效率的关键。Solar powered hollow fiber membrane liquid dehumidification system is an efficient,energy-saving,renewable and non-contact dehumidification system,which can effectively solve carry-over problem of traditional liquid dehumidification. In the present work,an exergy analysis model of solar powered hollow fiber membrane liquid dehumidification system is developed. The exergy of the component is analyzed. Effect of inlet paraments of air and cold-water,and solution flow rate on the system performance is investigated.The results show that the major factors affecting exergy efficiency of system are inlet air humidity,flow rate of inlet air,temperature of cold-water,and flow rate of cold-water. In the whole system,the biggest part of exergy destruction happens in solar collector. Improving the solar collector performance is the key way to improve the system exergy efficiency.
