SIMULATION STUDY ON THE PERFORMANCE OF BIPV/T-DSF AND FRESH AIR INTEGRATION SYSTEM

为提高光伏光热建筑一体化技术中光伏组件发电效率,充分利用其光热能量,同时满足室内人员对新风的需求,本研究将光伏光热建筑一体化技术与双层皮玻璃幕墙相结合,组成BIPV/T–DSF与新风一体化系统。以沈阳市一间30 m2的卧室为研究对象,通过实地测量室内污染物浓度并进行系统仿真模拟,对室内空气质量状况进行评估,并对系统的热电性能、空气通道内流场的流动特性进行研究。结果表明:系统运行时,冬季热效率达到0.22,电效率达到0.178;夏季电效率由原来的0.151提高到0.156。新风对于室内甲醛浓度有较好的净化效果,系统通风运行20 min后,甲醛浓度即可稳定在0.033 mg/m3。

To improve the photovoltaic and thermal performance of building integration technology,fully utilize its photothermal energy,and meet the indoor air quality needs of occupants,this study combines the photovoltaic and thermal building integration technology with double-skin glass curtain wall to form a BIPV/T-DSF and ventilation integrated system.Taking a 30 m~2 bedroom in Shenyang as the research object,the study measures the indoor pollutant concentration in real-time and conducts simulation to evaluate the indoor air quality.It also studies the thermal and electrical performance of the system,as well as the flow characteristics of the air channel.The results show that when the system is running,the winter thermal efficiency is 0.22,and the electrical efficiency is 0.178.The electrical efficiency is increased from 0.151to 0.156 in summer.Ventilation has a good purification effect on indoor formaldehyde concentration.The formaldehyde concentration can stabilize at 0.033 mg/m3 after the system ventilated for 20 minutes.
