摘要: 为提高太阳能光伏/光热(PV/T)集热器全年运行效率,提出一种新型管板式太阳能PV/T集热器结构,并针对该集热器光热传递与光电转换过程进行分析,建立水和空气同时运行时的二维非稳态传热数学模型;在验证模型可靠性的基础上,模拟研究空气流道高度和空气流量等设计参数对PV/T集热器光热、光电特性的影响。结果表明,空气流道高度为15 mm时,PV/T集热器光电光热综合性能效率最佳;在所研究的工况下,该集热器的光电光热综合性能效率为0.84~0.87。

Abstract: In this study, a solar photovoltaic/photo-thermal (PV/T) tube-plate type collector with new construction was proposed,in order to improve the overall utilization efficiency of solar energy. The photoelectric conversion and heat transfer process of the collector was analyzed and a two-dimensional non-steady state energy conversion model was developed. The reliability of the model was verified. Based on that, the effects of design parameters, including the height of the air channel and the air flow rate, on the performance of the PV/T collector were studied. The simulation results indicated that the best performance of the PV/T collector was achieved when the air flow channel height was set to 15 mm. Under the simulation conditions, the overall efficiency of the collector is about 0.84-0.87.

Key words: solar collectors, conversion efficiency, numerical simulation, PV/T, tube-plate type, air flow channel height
