摘　　要：针对广州亚运城采用的双水箱太阳能集热系统进行了运行监测,与传统单水箱太阳能集热系统比较,分析得出两种系统集热效率差异的原因;同时,利用实测数据优化双水箱太阳能集热系统的运行工况发现,通过提高集热水箱放水量与降低集热水箱定温放水控制温度可以进一步提升系统集热性能。Operating condition of the he double-water tank solar heat collecting system operating condition in Guangzhou Asian Games Town was monitored. Compared with the traditional single-water tank solar heat collecting system, the heat collecting efficiency difference between these two systems has been found by analysis. Meanwhile, throught the optimization of the double-water tank soler heat collecting system operation by measured data, it was found that the system heat collecting efficiency could be improved further through increasing the water flowage and decreasing the triguring constant temperature for waterdrainage of the heat collecting water tank.
