摘要
为改进溶液除湿系统的性能,提出了一种应用太阳能光伏再生的方法.通过离子交换膜分离溶液中的溶质与水分,从而再生除湿溶液,利用太阳能光伏发电提供再生过程所需的能量.对光伏驱动的溶液除湿空调系统的再生原理与系统流程进行了介绍,建立了除湿再生部分的模型,对各部分进行了质量能量平衡的分析,并将新方法与传统光热再生方法的性能进行了分析比较.结果显示:新方法减小了高环境湿度的不良影响,提高了稳定性;新方法减少了系统对环境的污染;与有热回收的传统方法相比,新方法的性能与之相当,与无热回收的传统方法相比,新方法系统性能高出20%以上,在太阳辐射不足的情况下,新方法的再生性能可达到传统热再生方法的2倍以上.
To improve the performance of the liquid dehumidification air-conditioning system,a so-lar photovoltaic regeneration method is proposed.By ion-exchange membrane,solute is separated from water in solution and liquid desiccant is regenerated.The electric energy for separation comes from the solar photovoltaic power.The principle of the liquid dehumidification air-conditioning sys-tem driven by photovoltaic power and the flow chart of the new system are introduced.The models of the dehumidification and regeneration process are developed.The mass and energy balance are ana-lyzed.The performance of the new system is compared with that of the traditional thermal heat driven system.The results show that the new method can reduce the unfavorable influence from the high air humidity and improve the reliability.It also reduces the pollution of the environment.The perform-ance of the new system is as good as the traditional system with the thermal recovery method and more than 20%higher than the traditional system without the thermal recovery method.When lack of solar irradiation,the new system can achieve a performance as high as twice that of the traditional system.
