摘　　要：文章针对寒冷地区冬季双层光伏窗办公建筑,利用Energyplus软件模拟研究了不同运行模式下双层光伏外窗对建筑节能特性的影响。首先,结合典型气象条件下光伏玻璃表面温度和发电量的实验测量数据,验证了Energyplus软件传热和发电模型的可靠性;在此基础上,对不同运行模式双层光伏外窗的热电性能及其对建筑采暖能耗的影响进行对比研究;最后,从降低建筑净能耗的角度出发,提出了双层光伏窗通风外窗的优化运行控制策略。结果表明,寒冷地区冬季工况下,在是否考虑建筑新风需求及新风负荷的情况下,采用送风式或优化运行双层光伏通风外窗的运行模式,不仅降低了建筑采暖能耗,同时还提高了光伏电池发电效率,更有利于建筑节能。In consideration of office buildings located in cold regions of China and installed with double-paned photovoltaic windows in winter,this paper,using Energyplus,conducted simulation study on the influence of double-paned photovoltaic windows on the energy-saving performance of buildings under different operating modes.This paper firstly combined the experimental measurement data of PV glass surface temperature and generating capacity under typical meteorological conditions to verify the reliability of the Energyplus software heat transfer and power model;on this basis,conducted comparative study over the thermoelectric performance of double-paned photovoltaic external windows with different operating modes and their effects on building heating energy consumption.Finally,from the perspective of reducing building net energy consumption,this paper presented the optimal operation control strategy of double-paned photovoltaic window external ventilation window.The results indicated that,under winter operating conditions in cold regions,and in consideration of fresh air requirements and fresh air load of the building,the air supply or optimized operation mode for double-paned photovoltaic not only reduces the building heating energy consumption,but also improves the power generation efficiency of photovoltaic cells,more conducive to building energy conservation.
