摘要(Abstract)：

建立了光伏/光热系统的电学模型和热学模型,通过耦合与解耦获得夏日、冬日的系统运行特性,分析了辐照值、环境温度以及风速对系统输出效率的影响。结果表明,无论夏日还是冬日,辐照最强时刻系统产生的电能、热能最多;冬日因辐照时间短,环境温度低,产生热能增益的时间低于夏日,存在结冰、结冻风险;系统输出效率受风速影响程度有限,风速提高时,系统电效率基本不变而热效率略降0.14%。
The electrical model and thermal model of the photovoltaic thermal system are established. By coupling and decoupling the electrical model and thermal model, the operating performance of the integrated system in summer and winter scenarios is obtained, and the effects of irradiation value, ambient temperature and wind speed on the output efficiency of the integrated system are analyzed. Results show that no matter in summer or winter, at the time of the strongest irradiation, the integrated system produces the most electric energy and thermal energy. However, the irradiation time in winter is short, the environment temperature is low, and the time to generate thermal gain is lower than that in summer, which has the risk of ice up and freezing. The output efficiency of the integrated system is limited by the influence of wind speed. With the increase of wind speed, the electrical efficiency remains unchanged, and the thermal efficiency decreases by 0.14%.
