摘　　要：提出一种新型的可与建筑南墙固定结合的非对称Lens-walled CPC,充分利用全反射、折射及镜面反射特性,在保证一定聚光比条件下,获得较大的接收角及较高光学效率。通过软件模拟,对其光学性能进行分析,并与非对称镜面CPC进行光学对比。研究结果表明,非对称Lens-walled CPC与建筑相结合优势明显,是聚光太阳能利用与建筑相结合的有效途径之一。A novel asymmetric Lens-walled CPC suitable for building south wall integration was put forward,the advantage of total reflection,refraction and specular reflection characteristics was fully used to obtain larger acceptance angle and higher optical efficiency under certain geometrical concentration ratio.The software simulation was used to analyze the optical performance and compare with optics of the asymmetric mirror CPC.The research results show that asymmetric Lens-walled CPC integrating with building has obvious advantages,and it is one of the effective ways to promote solar concentrating applications in buildings.
