摘　　要：随着可再生能源应用技术的不断发展,光伏(Photovoltaic,PV)电池已广泛安装于建筑屋顶并发电供能,受太阳辐射变化影响,建筑用能的稳定性亦受到挑战.针对上海市某办公建筑阴面房间,结合太阳能热电联产(Photovoltaic/thermal,PVT)供能技术,文中应用数值方法预测了典型年内PVT系统的电、热产量和建筑的冷热负荷,进而分析了多时间尺度上供能与负荷变化规律及两者的匹配特性.结果表明,对于相同面积的PVT和建筑房间,全年电、热产量大于负荷需求.系统逐日运行中,PVT系统可满足冬季供热需求的天数占比约为64%,满足夏季制冷需求的天数占比约为78%.With the continuous development of renewable energy application technology,photovoltaic(PV)cells have been widely installed on the roof of buildings for power generation.Affected by the change of solar radiation,the stability of building energy supply is also challenged.Aiming at the(PVT)supply for a nightside room in an office building in Shanghai,the loads of the building and the energy supply of the PVT system in a typical year were predicted by numerical calculation.The variations of energy supply and load on multitime scales and their matching characteristics were analyzed.The results showed that for the same area of PVT and building room,the annual electricity and heat output was greater than the annual load.In the daily operation of the system,the number of days in which the PVT met the demand of heating in winter accounted for about 64%and that for the demand of cooling in summer accounted for 78%.
