【摘要】 详述了一种新型的斜坡太阳能增湿-除湿海水淡化系统的结构和运行原理,并搭建了实验装置模拟该系统性能。通过改变加热板加热功率,研究系统参量对斜坡式增湿-除湿海水淡化系统的影响。实验研究结果表明:斜坡式增湿-除湿海水淡化系统能够稳定产水。在一定工况下,产水量比不采用冷凝器除湿的烟囱海水淡化系统能提高52.1%。随着加热功率增加,日淡水产量增加,但是热损和烟囱出口湿空气损失也会增加,导致日淡水产量增速降低。当加热功率为500 W时,系统日淡水产量为11.9 kg·m^-2·d^-1,系统效率为15.9%,盖板表面热损为50.9 W·m^-2。更多还原

【Abstract】 A new solar chimney humidification and dehumidification system for sea water desalination is proposed and described in this study.An experimental setup is built to analyze the performance of the new system.The influences of the parameters to the system are analyzed through changing the heat flux of the heating plate.Experimental study results show that the system can generate fresh water steadily.Under certain conditions,the fresh water generate rate is 52.1% larger than the system without the condenser.With the rise of the heating flux,the water production rate increases,meanwhile,the heat loss and moist air loss at the chimney outlet both increase,which decreases the growth tendency of fresh water production.When the heating power is 500 W,the water production rate is 11.9 kg-m^-2·d^-1,system efficiency is 15.9%,and the surface heat loss from cover is 50.9 W·m^-2.更多还原
