A Design of Spherical Refractive Solar Collector with Low Concentration

In this paper, an even low-magnification by light solar concentrator with the use of the spherical mirror's refraction is designed. The calculation of the concentration ratio and the volume of the concentrator are given, and the concentrator on the unit inter-shading problem is discussed. The relationship between incident angle and optical efficiency is analyzed, and solar concentrator tracking control mode is designed in this article. The simulation experiment results show that this spherical refraction solar concentrator is able to be applied to ensure the condenser unit to absorb ray intensity as five times as the ratio one under the conditions of mutual non-shading.
