摘要
本文在合肥地区对带有太阳能微型直流风机的PV-Trombe墙体系统对热箱热环境和光伏电池电性能的影响进行了实验研究。结果表明:在室外气候条件相似的前提下,太阳能微型直流风机加快了空气流道与室内空气的热循环,使更多的热量被带入室内,安装该风机时,室内温度与环境温度的温差高于无风机的工况,最大值高出2.3℃,且光伏组件的光电效率亦高于无风机时的工况。
In this paper, the influences of photovoltaic-Trombe wall equipped with solar DC-fan on thermal environment of hot-box and electrical efficiency of PV cells in Hefei had been experimentally investigated. The results indicated that solar DC-fan could quicken the thermal circulation of indoor air and air duct under the similar ambient weather conditions, as a result, much more heat was brought into the hot-box. Furthermore, when the solar DC-fan was in operation, the air temperature difference between the indoor and ambient environment was much higher than the fan was not operated, the maximum value was of 2.3 ℃, and the electrical efficiency was also higher when the solar DC- fan was ooerated.
