摘　　要：针对淡水资源短缺的问题,设计制作了一种利用太阳能或者其他余热驱动的管式海水淡化装置.通过对装置的每小时产水量及装置内各测点温度进行测试,对装置的性能进行了定功率和定温度供热的实验研究.定功率实验结果表明,实验装置的性能系数最高能达到1.5左右;装置的产水量达到了20.078 kg/(m2.d),相比传统装置有很大的提高.定温加热的实验结果表明,运行温度的增加可以提高装置的产水量.在相同实验条件下,多级装置相比单级装置能获得更高的产水量.Aiming at the problem about the lack of freshwater, a new tubular solar desalination unit is developed and its performance is tested in this research. Under the conditions of constant power and temperature, tests were implemented to measure the quantity of water yield per hour and the temperature at measuring points. Experimental results shown that, compared with traditional desalination device, the performance was greatly improved. The maximum performance ratio of the unit could reach to 1.5, and the maximum water production reach to 20. 078 kg/（m^2· d） . The higher of the operating temperature, the more yield of freshwater. Moreover, in the same experimental conditions, two-stage device could get higher water yield than that from one-stage device.
