夏季一般采用外固定遮阳装置来调节太阳流入辐射，节约能源。然而，它们会在冬天阻挡有益的太阳辐射。本文提出并研究了一种光伏复合热电通风机（pv - tev）系统。PVT - tev系统不仅可以在夏季防止太阳直接辐射进入建筑物，而且可以在冬季通过空气型PVT与热电通风机系统耦合来加热新风。在一个房间里建造了一个PVT-TEV系统来测试系统。结果表明：冬季阳光充足时，PVT-TEV系统的工作性能主要受太阳辐射的影响；太阳辐射越强，PVT-TEV系统获得的热量越大，新风温度越高。PVT的平均电效率为10%，PVT - tev的平均热效率为26.7%，PVT - tev的平均光热系数为6.4。在雨天，室外新鲜空气流经热电通风机的热管换热器时被加热。工作电压越高，TEV系统获得的热量越多，TEV系统的coph越低。当工作电压为24 V时，PVT-TEV系统的平均copof为1.73。PVT-TEV系统为建筑外部遮阳装置和提供新鲜空气提供了一种积极和绿色的方法。
External fixed shading devices are generally used to adjust solar influx radiation and save energy in summer. However, they could block the beneficial solar radiation in winter. In this paper, a photovoltaic thermal-compound thermoelectric ventilator (PVT–TEV) system is proposed and investigated. The PVT–TEV system not only could prevent direct solar radiation from going into buildings in summer, but also could heat fresh air by the air-type PVT coupled with a thermoelectric ventilator system in winter. A PVT–TEV system was built in a room for testing the system. Results demonstrate that the performance of the PVT–TEV system is mainly affected by solar radiation when the system works in the sunny days of winter. The stronger the solar radiation is, the more the heat of PVT–TEV system gains and the higher the fresh air temperature is. The average electrical efficiency of PVT is 10%, the average thermal efficiency of PVT–TEV is 26.7% and the average COPhof PVT–TEV is 6.4. In the rainy day, the outdoor fresh air is heated when it flows through heat pipe exchangers of the thermoelectric ventilator. The higher the working voltage is, the more the heat TEV system gains and the lower the COPhof the TEV system is. The average COPhof PVT–TEV system is 1.73 when the operating voltage is 24 V. The PVT–TEV system provides an active and green method for building exterior shading device and supplying fresh air.
