摘要:

为了改善寒地居住区日照不足状况,运用寒地居住区日照质量改良模型和光学折射原理,通过光学折射元件使太阳辐射转移到寒地居住区场地阴影区,扩大场地日照范围,改善日照质量．光学仿真模拟结果表明理论模型具备可操作性,并对关键参数进行验证与优化,初步确定模型的主要元件参数,推算动态日照时段下设备工作运行轨迹．寒地居住区场地日照质量得以改良,能够提高既定城市用地的建设容积率,使其开发使用效率得以提升,进而节约城市建设资金．

Abstract:

Insufficient insolation condition is one of the urgent problems to be solved in north China because of its cold climate and smaller solar elevation angle. To improve this situation, we are working on a theoretical model for optical facilities based on the principles of rays refraction, which can concentrate solar energy from larger scope to smaller scope, then insolation standard can be improved in the specific region. A theoretical model on the structures and working principles of the insolation lens is explained in detail, its validity is proved by optical simulation, and trajectory of rotating Insolation Lens is analyzed at length. This theoretical model could improve the insolation conditions of the existing residential buildings and reduce the land use in the urban construction processes.
