摘　　要：将双面光伏百叶与双层玻璃幕墙相结合,提出一种中置双面光伏百叶幕墙(bPVB-DSF),建立数值模型并通过实验对模型进行验证,开展敏感性分析以明确影响中置双面光伏百叶幕墙系统性能的关键参数,最后对比不同类型幕墙系统的热电特性。研究表明,模拟及实测结果具有良好的一致性,室外侧玻璃、双面光伏百叶以及室内侧玻璃温度的均方根误差分别为1.32、1.49和0.66℃。基于验证后的数值模型开展参数敏感性分析发现:双面光伏百叶的倾斜角度、叶片宽度、叶片间距及立面朝向对系统热电性能的影响较大,而空腔间距的影响很小。在夏季,相较于双层玻璃幕墙(DSF),中置双面光伏百叶幕墙得热量下降约17.38%;相较于中置单面光伏百叶幕墙(mPVB-DSF),中置双面光伏百叶幕墙可提高11.35%的发电量,而两者的热工性能相差较小。This paper introduced a novel approach by combining the bifacial photovoltaic blinds with a double skin façade,resulting in a bifacial photovoltaic blinds integrated double skin façade(bPVB-DSF).To evaluate the performance of bPVB-DSF,a numerical model was established and validated through experiments.Additionally,a sensitivity analysis was conducted to identify the key parameters that significantly influence the performance of the bPVB-DSF.Finally,the thermoelectric characteristics of different types of curtain wall systems were compared.The research findings demonstrated a high level of consistency between simulated and measured results,with root mean square errors of 1.32℃,1.49℃,and 0.66℃for outdoor side glass,bifacial photovoltaic blinds,and indoor side glass temperatures,respectively.Based on the validated numerical model,the sensitivity analysis revealed that the tilt angle,blade width,blade spacing and facade orientation of the bifacial photovoltaic louvers have a greater impact on the thermoelectric performance of the system,while the influence of cavity spacing is minimal.In summer,the bPVB-DSF exhibited a 17.38%reduction in heat gain compared to the double skin façade(DSF).Additionally,when compared to the mono-facial photovoltaic blinds integrated double skin façade(mPVB-DSF),the bPVB-DSF displayed an 11.35%increase in power generation,with negligible differences in thermal performance.
