摘　　要：在晴天天气条件下,对一款夹套换热水箱全玻璃真空管太阳能热水系统进行实验,并与普通全玻璃真空管太阳能热水系统进行对比.分析实验数据得,夹套热水系统与普通热水系统相比,日有用得热量较低,平均热损因数高.由温度曲线可知,夹套热水系统水箱内水温分层比普通热水系统更为明显.In this paper,a kind of all-glass vacuum tube solar water heating system with jacketed heat exchange water tank is tested under sunny weather,and compared with a kind of ordinary all-glass vacuum tube solar water heating system.From the experimental data,the all-glass vacuum tube solar water heating system with jacketed heat exchange water tank has lower daily useful heat gain and higher average storage tank heat loss coefficient than the ordinary all-glass vacuum tube solar water heating system.From the operating curve,the water temperature stratification is obvious in these two water tanks,especially in the lower level of water tank,and the jacket heat exchange water tank is more obvious.
