菲涅尔透镜提高太阳能利用率的研究
Research on Fresnel Lens for Improving Utilization of Solar Energy
摘要
随着经济的发展,能源短缺,太阳能越来越受到重视。采用聚光器可提高太阳照射在单位面 积上的能量密度,从而克服太阳能分散性的缺点。本文主要介绍了太阳能聚光器的特点,分析了菲涅尔透 镜的结构、优点及成像特性。通过实验,分析了菲涅尔透镜在提高太阳能利用率时的各种损失因素。
Abstract
With the development of economy, the shortage of energy resource is becoming serious and more and more attention is paid to the utilization of solar energy. Because a concentrator can be used to improve the energy density in a unit area, it can reduce the dispersion of solar energy. The characteristics of a solar concentrator is mainly presented. The structure, advantages and imaging features of a Fresnel lens are analyzed. Various loss factors which may occur when the Fresnel lens is used to improve the utilization of solar energy are analyzed experimentally.
