外侧镀铝膜风琴帘的遮阳性能研究
Study on shading performance of external aluminized film organ curtains
摘要：
有效的内遮阳可适当降低建筑夏季冷负荷，改善室内环境。提出了一种新型内遮阳设施——外侧镀铝膜风琴帘，并测试比较了传统卷帘、传统风琴帘、外侧镀铝膜风琴帘3种内遮阳设施的遮阳隔热性能。以实测值校核理论值的方式分析得出3种窗帘的遮阳系数。结果表明，外侧镀铝膜风琴帘的遮阳系数仅为0.15，相比于传统窗帘，其遮阳和隔热性能更佳。
Abstract：
The effective internal shading can reduce the building cooling load and improve the indoor environment. Presents a novel concept of internal shading facility—external aluminized film organ curtain. Tests and compares the shading performances of traditional rolling shutter, traditional organ curtain and the novel organ curtain. By means of checking the theoretical value with the measured value, obtains the shading coefficients of the three curtains. The results show that the shading coefficient of the external aluminized film organ curtain is 0.15, which is the smallest and has best shading performance compared with the traditional curtains.
