摘要
提出了带有PV的新型Trombe墙结构,建立了二维的光伏玻璃板以及PV-Trombe墙系统的数理模型,获得了系统的温度场、太阳电池的电性能和室内得热。模拟结果表明：根据该文所采用的实测气象数据,在特定的模拟工况下,光伏玻璃板上的光电池部分和无光电池部分的温差最大可达10．58℃；有无PV-Trombe墙房间的温差在3d内最大可达13．22℃；运行7d后每天温度能维持在14℃左右。
A novel Trombe wall with PV cells is presented in this paper. A two-dimensional model of PV glass panel and the model of the PV-Trombe system are established. The temperature distribution, electrical performance and heat gain of the PV-Trombe wall system are obtained respectively. Results show that according to the measured weather data and the given work condition, the temperature difference between the elements with and without PV cells on the glass panel reaches a maximum value of 10.58℃ ; the temperature difference between the room with and without PV-Trombe wall reaches a maximum value of 13.22℃ during 3 days; after 7 days＇ operation, the all-day temperature of the room with PV-Trombe wall is about 14℃.
