晴天模型下太阳能热水器加设平面反射板的能量增益研究

Studies on the Energy Enhancement of a Solar Water-heater Installed Plane Reflectors with Sunshine Model

在晴天模型下平板型太阳能热水器加设平面反射板后的能量增益与用太阳日射表实测到的实验数据比较，加设平面反射板后的能量增益显著，其中夏半年加下反射板效果优于加上反射板，冬半年加上反射板效果优于加下反射板。

The energy enhancement of a flat-plate solar water-heater installed plane reflectors was calculated with sunshine model, and compared with the experimental data measured with a solar actinometer. It was found that the energy enhancement was remarkable, and the efficiency using lower reflector was better than using upper reflector in summer and conversely in winter.
