摘要
文章利用TRNSYS动态模拟软件研究了在我国不同建筑气候带条件下,不同类型的太阳能PV/T集热系统和普通太阳能PT集热系统的各项性能。其中,太阳能PV/T集热系统分为基于普通玻璃型太阳能PV/T集热系统和基于Low-e型太阳能PV/T集热系统。文章探究了基于普通玻璃型太阳能PV/T集热系统和基于Low-e型太阳能PV/T集热系统的电、热性能,分析了这两种太阳能PV/T集热器的光电转化效率,以及这两种太阳能PV/T集热系统和普通太阳能PT集热系统的光热转化效率、太阳能贡献率、一次能源节约率、供热节能率和环境效益等参数。分析结果表明:普通太阳能PT集热系统的吸热量、太阳能贡献率、供热节能率和CO_(2)减排量均高于太阳能PV/T集热系统;与基于普通玻璃型太阳能PV/T集热系统相比,基于Low-e型太阳能PV/T集热系统的发电量降低了3.77%,但热效率、太阳能贡献率、一次能源节约率、供热节能率和环境友好度均较高。
This paper uses TRNSYS dynamic simulation software to examine the performance of different types of solar PV/T systems and common solar PT systems in various climatic zones of China.The PV/T system mainly explores the electrical and thermal performance of common glass-based PV/T system and Low-e PV/T system, analyzes the photoelectric conversion efficiency of two PV/T systems and the photothermal conversion efficiency, solar energy contribution rate, primary energy saving rate,fractional thermal energy saving and environmental benefit of three systems. The simulation results show that the thermal output, solar energy contribution rate, fractional thermal energy saving and carbon dioxide emission reduction of the PT system are higher than that of the PV/T systems;The power output of the Low-e PV/T system is 3.77% lower than that of the common glass-based PV/T system, but its thermal efficiency, solar energy contribution rate, primary energy saving rate,fractional thermal energy saving and environmental friendliness are better than common solar PV/T system.
