光伏板下喷雾降温的热环境模拟

Simulation of the Thermal Environment under Photovoltaic Panels with Spray Cooling

光伏发电带动了光伏农业的发展。然而,夏季光伏板下局部温度可达60℃,影响下面农作物等的生长,限制了系统性能的发挥。因此,本研究利用流体力学软件Fluent构建光伏阵列模型,开展光伏板下喷雾降温的热环境模拟,研究了喷雾降温技术在光伏农业中的应用。由模型的分析和计算,可得到初步的光伏板下的温度变化情况,为光伏板下喷雾降温的研究和应用提供了基础支持。

Photovoltaic power generation has driven the development of photovoltaic agriculture.However,the local temperature under the photovoltaic panels in summer can reach 60°C,which greatly affects the growth of crops below and limits the performance of the system.In this study,the fluid dynamics software Fluent is adopted to build a photovoltaic array model.The thermal environment under photovoltaic panels with spray cooling is simulated and the application of spray cooling technology in photovoltaic agriculture is studied.Preliminary results of the temperature variations under the photovoltaic panels are obtained,which provide basic support for the following study and application of the spray cooling technology under the photovoltaic panels.
