Abstract

The popularization of solar energy has been obstructed for a long time by its high price and low efficiency. Many researches and projects have been done with a variety approaches in those areas. This paper reviews two solar energy systems: daylighting system and photovoltaic/thermal (PV/T) system. The advantages and disadvantages of these systems are analyzed. An innovative parabolic trough solar lighting/thermal (PTL/T) system is proposed by combining the advantages of both systems. PTL/T system uses parabolic trough collector (PTC) as a solar collector. The sunlight collected is split by a cold mirror into visible light and inferred rays. The visible light and IR are used for daylighting and heating generation respectively. The basic structure of PTL/T is outlined and described. Its feasibility is analyzed by the calculation of system efficiency, annual savings by unit area of collector, break-even capital cost, and greenhouse gas reduction. The results show that the presented PTL/T system is a possible low price and high efficiency solution for the utilization of solar energy in building energy efficiency.

一种新型的抛物线槽太阳能照明和热系统，用于建筑节能

太阳能价格高、效率低，长期以来阻碍了太阳能的普及。在这些领域已经用各种方法进行了许多研究和项目。本文综述了两种太阳能系统:采光系统和光伏/热(PV/T)系统。分析了这些系统的优缺点。结合两种系统的优点，提出了一种创新的抛物线槽太阳能照明/热(PTL/T)系统。PTL/T系统采用抛物槽集热器(PTC)作为太阳能集热器。收集到的阳光被一面冷镜分成可见光和推断光线。可见光和红外线分别用于采光和供热。概述和描述了PTL/T的基本结构。从系统效率、集热器单位面积年节约成本、盈亏平衡资金成本和温室气体减排等方面分析了其可行性。结果表明，所提出的PTL/T系统为太阳能在建筑节能中的利用提供了一种低成本、高效率的解决方案。
