采用EnergyPlus建立光电玻璃集热蓄热墙的综合能耗数值模型,探究建筑运行过程中在热、光、电三者耦合作用下的建筑能耗变化情况。通过进行现场实验,验证综合能耗数值模型的传热、采光、发电模块的预测有效性。随后,将验证过的综合模型结合西北地区5个典型城市的气象数据进行综合能耗与节能效果分析。设置普通对照房间,得到最优综合性能的光电玻璃集热蓄热墙的具体节能效果。结果表明：西北地区的西安、兰州、银川、西宁、乌鲁木齐应用光电玻璃集热蓄热墙最佳透过率为30%、40%、50%、55%、60%;相较于普通房间,光电玻璃集热蓄热墙的最优能耗的节能率为18.4%、21.9%、22.7%、21.4%、16.9%。研究成果可为西北地区的太阳能光伏建筑一体化技术的具体应用提供参考,助力建筑节能行业发展。
Abstract
A comprehensive energy consumption numerical model for photovoltaic glass Trombe wall was established using EnergyPlus to explore the changes in building energy consumption under the coupling effects of heat, light, and electricity during building operation. Through on-site experiments, the predictive effectiveness of the comprehensive energy consumption numerical model for heat transfer, lighting, and power generation modules will be verified. Once again, the validated comprehensive model will be combined with meteorological data from five typical cities in Northwestern China to conduct a comprehensive analysis of energy consumption and energy-saving effects. Finally, set up a blank control room to obtain the collective energy-saving effect of the photovoltaic glass Trombe wall with the best comprehensive performance. The results show that the optimal transmittance of photovoltaic glass Trombe walls in Xi’an, Lanzhou, Yinchuan, Xining, and Urumqi in the northwest region are 30%, 40%, 50%, 55%, and 60%, respectively; Compared to ordinary rooms, the energy-saving rates of the optimal energy consumption of photovoltaic glass Trombe walls are 18.4%, 21.9%, 22.7%, 21.4%, and 16.9%, respectively. The research results can provide reference for the specific application of integrated solar photovoltaic building technology in Northwestern China, and jointly promote the development of the building energy-saving industry.
