摘要
在光伏建筑一体化中,带通风腔的光伏组件主要通过对流和辐射换热向外界进行散热,通风腔的设计不仅影响着组件的温度,而且影响着屋面的热工性能。为此,对带通风腔的光伏屋面进行理论分析和仿真模拟,提出最优方案,使得通风腔光伏建筑更具节能效果和经济性,加快光伏建筑工程化应用。
In the building integrated photovoltaic (BIPV),PV modules with ventilation cavity dissipate heat by convection and radiation, the design of ventilated cavity affects the component temperature and the thermal performance of the roof. Therefore, photovoltaic roof with ventilated cavity is analyzed by theoretical and simulation method, we put forward the optimal scheme to make photovoltaic building ventilation cavity more economical and speed up the photovoltaic building engineering application.
