不同建筑遮阳方式遮阳效果的实验研究

为对外中内三种遮阳方式的不同遮阳效果进行研究，搭建测量遮阳设施遮阳效果的实验台，分别对三种遮阳方式的太阳得热系数（SHGC）进行试验研究。通过对实验时间段内的太阳入射角和垂直面太阳辐射强度的理论计算，得出三种遮阳方式遮阳效果可比的时间段。结果证明不同遮阳方式相同百叶片放置角度的太阳得热系数，外遮阳最小，中间遮阳居中，内遮阳最大。同种遮阳方式不同百叶片放置角度的太阳得热系数随百叶片与水平面的夹角增大而变小。

EXPERIMENTAL STUDY ON SHADING EFFECT OF THREE DIFFERENT SHADING MODES

The test facility which is used to measure the shading effect of the shading device was set up for the study on the shading effect of three different shading modes.The solar heat gain coefficient （SHGC ）of the three shading modes was tested.The comparable time area was got by calculation of the solar incident angle and the vertical solar radiation.The result of the solar heat gain coefficient （SHGC）of the three shading modes in the same angle was got.The solar heat gain coefficient （SHGC）of the outside shading mode was little; The solar heat gain coefficient（SHGC）of the middle shading mode was mean; The solar heat gain coeffieient（SHGC） of the inside shading mode was great.The solar heat gain coefficient （SHGC）of the different angle in the same shading mode turned less when the angle turned greater.
