摘要
本文讨论了分析、计算反射板-热水器系统水箱平均水温的方法,并以昆明、拉萨、北京、呼和浩特和乌鲁木齐等有代表性的地区为例,计算了二分日和二至日的日能量增益系数。结果表明,加置反射板可较明显地提高热水器系统的水箱平均水温,且上反射板对热水器的增益效果优于下反射板。
A method of analysing and calculating the average temperature in water tank of solar heater system with reflector is presented. In this paper five typical regions such as Kunming, Lasa, Beijing, Huhehaote, and Wulumuqi are identified to calculate the coefficient of daily energy enhancement of such solar water heating system in the days of two epui-noxes and two solstices. Results show that, the average temperature in water tanks of solar heaters with plane reflectors will increase significantly and the coefficient of daily useful gainforthe system with upper reflector is higher than that with lower reflector.
