| 遮蔽系数 Shading Coefficient |
The ratio of solar energy that enters through a window compared to the energy entering a clear,
double strength sheet of glass; includes both energy transmitted through the window and energy
absorbed in the window.
指进入一窗户太阳热量与进入一透明无色双强度玻璃的之比。这里的热量包括穿过窗户的和窗户吸收的。
SC体现了玻璃体系的隔断阳光的能力或效率;
或:相同条件下,太阳辐射能量透过某玻璃组件的量与透过3毫米透明玻璃的量之比就是该组件的遮阳系数,用SC表示。
遮阳系数越小,阻挡阳光直接辐射的性能越好。 |
