基于双层皮通风幕墙结构,提出一种外置光伏百叶通风节能窗,充分利用遮阳百叶与光伏发电优势,高效采暖、发电与采光,营造舒适的室内光热环境。利用Design Builder和Energy Plus建立外置光伏百叶通风窗系统夏季工况的光-热-电耦合仿真模型。以普通双层玻璃窗为基准,对比分析了外置光伏百叶通风窗系统对自然采光、室内热环境的影响并预测其综合能耗。结果表明,外置光伏百叶通风窗自主采光能力较弱,但靠近外窗的2.0 m×1.5 m区域能满足自然采光要求且舒适性较好。热舒适（PMV）研究表明,整个夏季外置光伏百叶通风窗房间相较于普通双层玻璃窗房间更为舒适。外置光伏百叶通风窗系统节约33.90%空调能耗的同时产电84.69 kWh。相较于普通双层玻璃窗,外置光伏百叶通风窗系统综合节能34.64%~56.48%,具有较高的节能潜力。
Abstract
Based on the ventilated double-skin facade, an external photovoltaic blind ventilation window （PVBVW） has been proposed, making full use of the advantages of blinds and photovoltaic cells to achieve efficient heating, power generation, light regulation, and create a comfortable indoor lighting and thermal environment. A coupled optical-thermal-electrical simulation model of PVBVW system under summer condition was established using Design Builder and Energy Plus. Compared to a standard double-glazed window system, the impact of the PVBVW system on natural lighting and indoor thermal environment was analyzed, and its comprehensive energy consumption was predicted. The results shows that the daylighting of the PVBVW is weak, but the area within 2.0 m × 1.5 m closing to the external window can meet the requirements of natural daylighting and the comfort was better. The results of PMV research results indicats that the room of the PVBVW compared with that of the standard double-glazed window provides a more comfortable indoor thermal environment. The PVBVW system saves 33.90% of air conditioning energy consumption while generating 84.69 kWh of electricity during the summer season. Compared to the standard double-glazed window, the PVBVW system achieves comprehensive energy savings of 34.64%-56.48%, demonstrating a high energy-saving potential.
