摘要
复合抛物面型集热器(CPC)可将接收角范围内的入射光线按理想聚光比收集到吸热体上。根据CPC的这一光学特性,介绍了一种选择性太阳能隧道(SST)的设计,利用冬夏两季太阳高度角的差异,实现不同的吸热效果,从而达到夏季降温,冬季供暖的目的。
Compound parabolic concentrator （CPC） can collect all the rays in the extension of its collect angle. According to this characteristic of CPC, a design of a selective solar tunnel （SST） is introduced in this paper. The SST realizes different absorbing effect with different solar angle between summer and winter. So the SST can cool in the summer while heat in the winter.
