太阳能热水器加设平面反射板的实验研究

Study on the Experiment of Flat-Plate Solar Water Heater Added Plane-Reflector

用实验方法对平板型大阳能热水器加设上反射板、下反射板、双反射板系统与不加设反射扳系统进行了性能上的比较，得出了各种气候条件下（晴天、多云、阴天）的月平均有用能量增益值，并对加设反射板系统作了初步的经济效益分析。

The efficiency of flat-plate solar water heater added upper reflector, lowerreflector and double reflector was compared with the system without reflector byexperimentat. Month average utilizable energy enhancement in varied climates (sunshine,cloudy, overcast sky ) were geted. The economy benefit of adding reflectors system wasanalysed..
