摘要:
基于蒸汽压缩式制冷系统冷凝热和太阳能作为溶液再生过程热源的利用,构建了一种新型高效的冷凝热分段利用复合型溶液除湿空调系统,并采用ε-NTU模型对系统进行了理论分析.研究了室内显热负荷比、室外空气状态及新风比对系统性能的影响,并与未利用冷凝热的传统溶液除湿空调系统进行对比,得到系统节能的特性,即使在使用电加热辅助溶液再生时,系统性能仍然优于未利用冷凝热的溶液除湿系统,尤其在ta、RH较小时,系统性能提升更大.
Abstract:
In this paper,the condensation heat of vapor compression refrigeration system and solar energy are used as auxiliary heat source in the solution regeneration process.A novel hybrid liquid desiccant air conditioning system is established with efficiently sectional utilization of condensation heat.The ε-NTU model is used to conduct the theoretical analysis of the system.The paper studies the effects of indoor sensible heat load ratio,outdoor air condition as well as fresh air ratio on the performance of the system,and compared the results with the conventional liquid desiccant air conditioning system which does not utilize condensation heat as auxiliary heat source.It is concluded that even if electrical energy is used to assist regenerating solution,the system’s performance is better than that of the conventional system without utilization of condensation heat.The promotion will be more especially when ta and RH are relatively little.
