摘要
建筑遮阳是建筑隔热的一种方式,主要通过遮挡的方式减少太阳辐射热通过窗户、屋面、墙体进入室内。本文介绍了建筑遮阳的几种形式,并讨论了建筑遮阳在应用中的若干问题。指出目前对建筑遮阳技术的应用存在重玻璃遮阳轻构件遮阳、构件遮阳形式缺少优化、忽略南北方在建筑遮阳方面和传热方面的不同要求、对遮阳系数的理解失误和对内遮阳的作用评价不明确等现象。最后,强调加强建筑遮阳的应用以取得更好的节能效果。
Building sun-shading is a way of building heat insulation, mainly through the way of block to reduce solar radiation through the window, roof and wall into the room. From the essay, the author tells the forms of building sun- shading and discusses some problems concerning practical application of sun-shading. This paper points out that the application of the technology of sun-shading exists in the following phenomenon： paying attention to glass sun-shad- ing and ignoring structures sun-shading, lacking of optimization in structures sun-shading form, ignoring the differ- ent requirements at the sun-shading and heat transfer in the south and north, the wrong understanding of the shading coefficient and unclear evaluation to the role of the internal shading. Finally, the author emphasizes that strengthen the application of building sun-shading to get further energy-saving effect.
