The Development of building integrated photothermal voltaic(BIPV/T)systems

建筑集成光伏光热(BIPV/T)系统将太阳能光伏(PV)、太阳能集热器与建筑立面一体化巧妙结合,实现了发电和热能的协同产出。BIPV/T系统可以显著提高太阳能效率,并同时降低建筑的冷热负荷。BIPV/T系统分为两大类,即光伏光热/空气建筑一体化(BIPV/Air)和光伏光热/流体建筑一体化(BIPV/fluid)系统。对BIPV/Air系统的性能优化策略进行了总结,包括通风模式与强化传热结构。对BIPV/fluid系统中的BIPV/water和BIPV/T热泵系统进行了深入探讨,包括数学模型、性能改进和优化运行方法。寻找到一些改进策略的有效方法。该研究对于提高BIPV/T系统的能源效率和经济性具有意义。

The Building Integrated Photovoltaic/Thermal(BIPV/T)system cleverly integrates solar photovoltaic(PV)and solar thermal collectors with building facades,achieving synergistic generation of electricity and heat.This integration facilitates the simultaneous generation of electricity and thermal energy,significantly enhancing solar energy efficiency while reducing the building's heating and cooling loads.The paper provides an overview of the development of BIPV/T systems,categorizing them into two main types:Photovoltaic/Air Building Integrated(BIPV/Air)and Photovoltaic/Fluid Building Integrated(BIPV/fluid)systems.Performance optimization strategies for BIPV/Air systems have been summarized,including ventilation modes and enhanced heat transfer structures.In-depth discussions have been conducted on BIPV/Water and BIPV/T heat pump systems within BIPV/Fluid systems,including mathematical models,performance enhancements,and optimization methods.Effective methods for improving strategies have been identified.This research provided valuable guidance for enhancing the energy efficiency and economic viability of BIPV/T systems.
