摘要:
通过上海地区典型年逐时气象参数和实测的各向异性太阳辐射数据对比分析了不同的遮阳控制策略, 分析表明同时控制温度和太阳辐射的策略遮阳时数远小于只控制太阳辐射的策略,控制太阳总辐射的策略北向基本不需要遮阳,控制太阳直射辐射的策略随着直射辐射控制阀值的减小,遮阳时数逐渐增加.在此基础上研究了季节性因素、玻璃材质、不同倾角和朝向对遮阳时数的影响,结果表明:不同遮阳策略的各向遮阳时数分布规律呈偏西向分布、偏东向分布和对称型分布;直射辐射阀值较低的控制策略(策略11)节能率较高,对于建筑立面遮阳应优先考虑采用.随着玻璃的太阳得热系数(SHGC)的减小,控制太阳直射辐射的策略(策略9~11)遮阳时数相应地减少;遮阳时数随着倾角的增大而减小,正南向最大,正东和正西向较为相似,正北向最小.
Abstract:
Different shading control patterns are comparatively analysed by hourly meteorological parameters of Shanghai typical meteorological year and measured anisotropic solar radiation. The analysis shows that the shading hours of controlling temperature and solar radiation patterns are shorter than only control solar radiation patterns. For control global solar radiation patterns, shading is not required on the north. With the direct radiation control threshold reduced, the shading hours of controlling direct solar radiation patterns is gradually on the increase. And then seasonal factors, glass materials, different angle and orientation effect on shading hours are studied. Results show that, distributions of shading hours of different shading control patterns are westly, eastly and symmetrical. Direct solar radiation threshold lower control strategy(Strategy 11)energy saving rate is higher, and the building fa?ade shading should give priority to it. With the glass solar heat gain coefficient (SHGC) decreases, shading hours of control direct solar radiation Strategy (Strategy 7~11) are reduced accordingly. Shading hours are decrease as the inclination angle increases, and south is the largest, while east and west are similar, north is minimum
