摘　　要：光伏遮阳装置(Photovoltaic shading devices,PVSDs)能够结合建筑外遮阳和光伏发电组件,在减少室内冷负荷的同时为建筑提供可再生能源,是实现建筑近零能耗的有效途径。垂直光伏百叶可以避免水平百叶光伏遮阳装置的自遮挡效应,更充分地利用太阳辐射,延长光伏组件的使用寿命。以广州市典型办公室为对象,应用敏感性分析得到影响垂直光伏百叶遮阳装置的关键参数;通过全局优化得到各朝向能源性能最优的工况;对各朝向最优工况的能源性能、采光性能、减碳潜力展开分析。结果显示:百叶旋转角度A_(P)与百叶间距D_(P)是影响垂直光伏百叶装置能源性能的关键参数;在各朝向下,垂直光伏百叶装置均能够大幅减少所在房间的能源消耗,显著提升室内光环境,并展现出较高的减碳潜力。Photovoltaic shading devices(PVSDs)can effectively achieve near-zero energy consumption in buildings by combining external shading and photovoltaic power generation modules,reducing indoor cooling loads while providing renewable energy.Vertical PV louvres can avoid the self-shading effect of horizontal louvres in PV shading devices,making fuller use of solar radiation and extending the service life of PV modules.This paper analyses the energy performance,lighting performance,and carbon reduction potential of the optimal working conditions in each direction for a typical office in Guangzhou.Sensitivity analysis is applied to identify the key parameters affecting the vertical PV louvre shading device.The optimal working conditions for energy performance in each direction are obtained through global optimisation.The results indicate that the louvre rotation angle A_(P) and louvre pitch D_(P) are the key parameters that affect the energy performance of the vertical PV louvre device.The device is capable of significantly reducing the energy consumption of the room in all orientations,improving the indoor light environment,and showing a high potential for carbon reduction.
