中文摘要：

利用实际天气的太阳辐射值，根据一套低温四效太阳能海水淡化系统稳态实验数据，通过模拟计算，研究分析与该海水淡化系统匹配的太阳能集热系统参数，给出太阳能集热系统集热器面积和储热水箱容量、海水淡化系统启动和暂停温度等参数的最佳取值范围，计算了该装置的年淡水产量，为太阳能海水淡化装置的设计提供一种有效地方法。

英文摘要：

Based on the steady-state experimental data of a low-temperature multi-effect solar desalination and the hourly solar radiation data, the parameters of solar heating system were analyzed and computed by simulation. The optimal valued scopes of the solar collector areas and the tank volume of the solar heating system and the star-up and break temperature of the desalination system were given. The yearly yield of freshwater was estimated, too. The discussion in the paper is helpful for the solar desalination study.
