摘　　要：BIPV控制中心把空冷型PV/T构件整合到建筑外墙中,实现了太阳能光电光热一体化高效综合利用。设置排风机与南墙东侧的PV/T构件相结合,夏季和过渡季进、排风电动百叶开启自然散热。冬季开启排风机,热空气送至地板下的蓄热混凝土进行蓄热,实现光伏余热直接热利用。本文对此系统进行了实验测试,蓄热混凝土系统平均温升5.8℃,蓄热效果良好,具有推广应用价值。BIPV control center integrates the aircooled PV/T components into the external wall of the building,realizes the efficient and comprehensive utilization of solar energy in the building.The supply fan was combined with the PV/T component on the east side of the south facade of the building.In summer and transition seasons,the electric louvers were turned on for natural heat dissipation.In winter,the exhaust fan was turned on and the hot air was sent to the heat storage concrete under the floor for heat storage,so as to realize the direct heat utilization of photovoltaic waste heat.In this paper,the experiment of this system was carried out.The average temperature increase of the thermal storage concrete system was 5.8℃,indicating that the system has good thermal storage performance,and it has the potential of application.
