Study on Energy-saving Characteristics of Novel BIPVT Ultra-low Energy Building

将微热管阵列应用于建筑一体化光伏光热(BIPVT)组件,设计了多能互补耦合热泵供能系统,实现了太阳能与空气能高效互补利用,并搭建了新型BIPVT超低能耗建筑。同时建立了BIPVT建筑的仿真模型,并将其与BIPV幕墙建筑和普通参考建筑的产能与用能进行模拟与对比分析。结果表明,新型BIPVT建筑全年累计空调负荷为3033 k W·h,相对于BIPV幕墙,建筑负荷降低了32.9%。相对于参考建筑,负荷增加了8.6%。新型BIPVT建筑能耗综合值为113.5 k W·h/(m^(2)·a),相对于BIPV幕墙和普通墙体围护结构,新型BIPVT建筑综合节能率分别为38.5%和62.2%。本研究为超低能耗建筑的应用提供了新的技术方法与理论依据。

The micro heat pipe array was applied to building integrated photovoltaic-thermal(BIPVT)module.A novel BIPVT ultra-low energy building was proposed and constructed,which consists of multi-energy complementary energy supply system based on the efficient complementary utilization of solar energy and air energy.The building energy consumption model is established and the BIPVT building energy consumption was compared with the BIPV and reference building,and the difference of energy consumption and the energy generated by are analyzed.According to the results,the annual loads of BIPVT building is 3033 k W·h,which is 32.9% lower than BIPV building.Moreover,the building energy consumption of BIPVT building is 113.5 kW·h/(m^(2)·a).Compared with BIPV and ordinary wall,building energy saving rate of BIPVT building is 38.5% and 62.2%,respectively.
