| 中文摘要: |
| 针对PV/T的研究主要以实验方法为主，缺乏理论依据的问题，利用管道液体对流传热理论，对PV/T水冷装置的热吸收能力和传热时延进行了初步分析，研究了流速对装置性能的影响。通过设计一个U型管水冷PV/T进行模型实验，表明了在功能方面，PV/T既可以实现太阳能的热利用，也可以降低组件温度，从而提高光伏发电效率。在性能方面，PV/T的热吸收能力受流速的影响很大，需要平衡热吸收能力与水泵驱动功率之间的矛盾。 |
| 英文摘要: |
| At present, the research of PV/T is mainly based on experimental methods, and lacks of theoretical analysis. In this paper, based on the theory of liquid convective heat transfer, the heat absorption capacity and heat transfer delay of the PV/T water - cooling system are analyzed. The effect of flow velocity on the performance of the device was studied. Then, a U-tube water-cooled PV/T system was designed and simulated. The experimental results show that PV / T can both improve the efficiency of photovoltaic power generation by reducing the temperature of solar modules and realizing the heat utilization of solar energy. In terms of performance, the heat absorption capacity of PV/T is significantly affected by the flow rate, and the contradiction between the balance of the heat absorption capacity and the pump drive power is required. |
