建筑光伏一体化瓦屋面构造优化OA

This paper proposes a novel building-integrated photovoltaic(BIPV)tile module,builds an experimental test rig in Beijing,and establishes a corresponding numerical model to optimize the structural parameters of the module,addressing the heat dissipation problem of BIPV tile roofs.Taguchi method and Computational Fluid Dynamics(CFD)numerical simulation were employed to design and simulate orthogonal schemes,optimizing photovoltaic tile roof structure for the first time by considering three factors:height of counter batten,radius of heat emission hole and hole spacing.The results indicate that the radius of heat emission hole has the most significant impact on the temperature of the photovoltaic backsheet,followed by hole spacing and the height of counter batten.In the Beijing area,the optimal scheme features a counter batten height of 60 mm,radius of heat emission hole of 60 mm and spacing between heat emission holes of 250 mm.Compared with the control group,the temperature of the photovoltaic panel backsheet is reduced by 1.43℃.
