摘　　要：太阳能真空管加热饮用水的研究不仅可以检验真空管的性能而且拓展了真空管的应用空间。本文使用TMC-2Z便捷式太阳能集热管热性能测试系统,对比了非聚光、平面反射聚光以及复合CPC槽式聚光全玻璃真空管加热水的情况。实验结果表明:复合式CPC槽式聚光太阳能真空管对水加热效果最好,其加热水平均时间为90.25min,一天可以对水烧开4次,获得开水1815ml,相当于市面出售550ml矿泉水三瓶。若使用标准真空管加热饮用水,可以获得热量537.9MJ同时获得热水量6534ml,相当于市面出售550ml矿泉水11瓶。本实验的完成不仅检测了真空管集热器加热水的效果,而且为太阳能饮水机的开放和研究提供重要的理论依据。The research of solar vacuum tube heating drinking water can not only test the performance of vacuum tube but also enlarge the application space of vacuum tube.In this paper,by using the thermal performance test system of TMC-2Z,compares to non-condensing,plane-reflecting concentrating,and composite CPC trough type all-glass vacuum tube heating water.The experimental results show that in a cycle,the best heating effect is a hybrid CPC-type concentrating solar vacuum tube.The average time for the heating drinking water is 90.25 minutes.The water can be heated 4 times a day and 1815 ml of boiling water can be obtained one day,equivalent to three bottles of 550ml mineral water on the market.If a standard vacuum tube is used to heat water,the calorific value 537.9 MJ and the total amount of hot water obtained,equivalent to 11 bottles of 550 ml of mineral water on the market.The completion of this experiment not only tested the effect of the vacuum tube collector heating water,but also provides important theoretical data for the development of solar water dispensers.
