定义溶液冷却与加热过程的能量匹配系数, 分析得到该系数受除湿与再生侧溶液流量比的影响较大, 而受太阳能加热器出水温度和冷却水流量的影响小.增加除湿与再生侧的溶液流量比, 降低太阳能加热器出水温度, 增大冷却水流量, 同时调控3个参数可使系统的能量供需平衡.通过中国南方典型湿热气候条件实例分析, 得出整个系统的能量达到匹配时的参数, 系统的性能得到有效提高, 为系统的实际运行提供指导.“,”In this research, the index of energy matching is defined to evaluate the energy matching of the solar energy driven membrare-based liquid desicant system. It is greatly affected by the solution flow ratio of dehumidification to regeneration, but less affected by the outlet temperature of solar collector and the cooling water flow rate. The capacity matching can be achieved by increasing the solution flow ratio of dehumidification to regeneration, decreasing the outlet temperature of solar collector and increasing the cooling water flow rate. The optimal parameters are obtained as the supply and demand of energy is well matched both in the dehumidification and regeneration processes under the typical weather conditions in hot and humid Southern China. They are helpful for the system performance improvement.
