摘　　要：设计了一种具有强化凝结面的多级迭盘式太阳能蒸馏器。对其在实际天气下的升温特性及产水性能进行测试,得到其内部各级海水运行温度的全天变化曲线以及全天总产水量的变化曲线。对装置顶层腔体全天进光率进行推导,根据实验数据进一步得到海水淡化主机全天工作效率。实验结果与文献[4]中的稳态实验结果进行对比分析,探索了该类装置在实际天气条件的产水特性,对其内部的热质传递规律进行初步研究。结果表明,该装置的日产水量可达约43kg(晴好天气下),性能系数可达1.54,是一种较理想的小型海水淡化装置。A multi-stage stacked tray solar distiller with folded and enhanced condensation faces was designed. Fieht test had been carried out in actual weather in order to obtain its characters of temperature variation and water production. Inner temperature and water production variation curves were given. Input sunlight ratio of top stage distillation chamber was deduced and the efficiency of desalination equipment was calculated. Comparison between field test and steady state test was finished. Actual weather working characters and inner mass-heat transfer principle of this multi-effect distiller was also analyzed. The results showed that the fresh water yield can reach up to 43kg/d and its performance ratio can reach up to 1.54 in fine weather, and this distiller is desired desalination equipment.
