摘要
建立了PV-Trombe墙系统及二维光伏玻璃板的数学模型,以实测数据为基础,模拟了不同光电池覆盖率对该墙体光电、光热性能及室内温度场的影响。模拟结果表明:随着覆盖率的增加,该墙体发电量和总效率增大,但热效率和室内温度降低;覆盖率对光电池发电效率影响很小,对室内温度影响较大;当覆盖率分别为0.207和0.873时,光电池发电效率降低不足0.5%,但前者的最高室内温度比后者高6.8℃。
Presented a novel photovoltaic-Trombe wall(PV-TW).Based on the actual measured weather data in Hefei,a detailed simulation model for photovoltaic-Trombe wall was presented.The simulation results show that as the coverage ratio increases,the electrical yield and the total efficiency of photovoltaic-Trombe wall increases,but the indoor temperature and the thermal efficiency of photovoltaic-Trombe wall decreases.The maximum indoor air temperature difference,corresponding to the lowest and the highest coverage ratio,can reach to 6.8℃ above.In addition,as the coverage ratio increases,the electrical efficiency of photovoltaic cell decreases,but the influence of coverage ratio on electrical efficiency is slight,less than 0.5 per cent.
