运行温度升高降低了光伏设备的效率。通过实验和数值模拟研究了相变材料在建筑物集成光伏温升中的应用。利用实验数据验证了本文建立的流体力学共轭二维有限体积换热模型求解N-S方程和能量方程的有效性。文中还报告了一个设计应用程序的参数研究。利用实验验证的数值模型对各种构型下系统内的温度、速度场和旋涡的形成进行了预测。对光伏表面不同日照温度和环境温度的温度分布预测表明，实现的温度缓和可以显著提高光伏幕墙的运行效率。(C)2004爱思唯尔有限公司。保留所有权利。
Elevated operating temperatures reduce the efficiency of photovoltaic devices. The use of a phase change material to moderate building integrated photovoltaic temperature rise has been investigated by experiments and numerical simulations. Experimental data are used to validate the previously developed two-dimensional finite volume heat transfer model conjugated hydrodynamically to solve the Navier-Stokes and energy equations. A parametric study of a design application is also reported. Temperatures, velocity fields and vortex formation within the system were predicted for a variety of configurations using the experimentally validated numerical model. Temperature distributions predicted for different insolation and ambient temperatures at the photovoltaic surface show that the moderation of temperature achieved can lead to significant improvements in the operational efficiency of photovoltaic facades.
