摘　　要：建筑屋面在日间接收大量太阳辐射,影响建筑热舒适与空调制冷能耗。光伏地砖技术日渐成熟,将其用于建筑屋面能够在不影响人员室外活动的前提下实现太阳能资源的清洁利用。普通光伏地砖在强太阳辐射下表面温度过高,不仅影响室外活动人员的热舒适,还造成光伏发电效率下降。本研究提出一种相变光伏地砖结构并开展夏热冬暖地区室外试验测试,结合CFD模拟技术分析相变材料厚度、相变温度及气象条件对相变光伏上人屋面热性能的影响,为光伏发电技术在建筑围护结构应用提供新思路。Building roofs receive a large amount of solar radiation during the day,which affects building thermal comfort and air conditioning and cooling energy consumption.Photovoltaic floor tile technology is becoming increasingly mature,and its use on building roofs can achieve clean utilization of solar energy resources without affecting people's outdoor activities.The surface temperature of ordinary photovoltaic floor tiles is too high under strong solar radiation,which not only affects the thermal comfort of outdoor activities,but also causes a decrease in photovoltaic power generation efficiency.This study proposes a phase-change photovoltaic floor tile structure and conducts experimental tests outdoor.It combines CFD simulation technology to analyze the effects of phase-change material thickness,phase-change temperature and meteorological conditions on the thermal performance of phase-change photovoltaic roofs,and provides guidance for the application of photovoltaic power generation technology in building envelopes.
