摘要
光伏-相变材料耦合(photovoltaic integrated with phase change material,PV-PCM)系统可以显著降低光伏温度同时提高太阳能光电光热综合效率,在强化建筑围护结构保温隔热、改善室内环境质量和降低建筑能耗方面具有重要意义.本文介绍了 PV-PCM系统技术及原理,根据系统物理结构归纳了 PV-PCM系统的分类特点,并结合国内外最新研究成果概述了耦合系统仿真模型、关键参数特性与评价指标.基于系统与建筑的不同结合形式调研了系统应用现状,同时系统总结了耦合系统对建筑室内负荷、室内环境与空气质量影响的研究进展.研究发现PV-PCM系统能够实现太阳能综合利用、建筑节能和室内舒适性改善,但仍应加强对高效低成本PV-PCM系统发展及其耦合匹配分析,以实现PV-PCM系统性能提升同时拓展其与建筑有机结合.该研究将为PV-PCM系统性能强化及其建筑大规模应用提供新的思路与方法.
Abstract
The photovoltaic integrated with phase change material(PV-PCM)system can significantly reduce the photovoltaic temperature and improve the comprehensive efficiency of solar photovoltaics,which is of great significance in strengthening the thermal insulation of the building envelope,improving the indoor environmental quality and reducing the energy consumption of the building.This paper introduced the technology and principle of the PV-PCM system,summarized its classification characteristics according to the physical structure of the system,and provided an overview of the simulation model,key parameter characteristics,and evaluation indicators of the coupling system based on the latest research results at home and abroad.Based on the different combinations of system and building,it further investigated the application status of the system,and systematically summarized the research progress of the coupling system on the indoor load,indoor environment and air quality of the building.It is found that PV-PCM systems can achieve comprehensive solar energy utilization,building energy saving,and indoor comfort improvement.but the development of high-efficiency and low-cost PV-PCM systems and their coupling matching analysis should still be strengthened to improve its performance improvement while expanding its organic integration with buildings.This study will provide new ideas and methods for PV-PCM system performance enhancement and its large-scale application in buildings.
