摘　　要：鉴于目前呼吸式玻璃幕墙的研究中缺乏对太阳能二次透过率的研究,通过引入多孔介质模型简化中间遮阳装置,以动量守恒定理、热力学第一定律为基础,对不同流态下呼吸式玻璃墙内的流动进行分析,提取了影响太阳能透过率的主要因素,建立了基于π定理的太阳能二次透过率无量纲模型,并采用最小二乘法辨识得到相应的参数。For lack of the research done on the secondly solar energy transmittance in double skin facade,in the paper,the dimensionless model founded on theπtheorem was developed and the corresponding parameters in the model were identified by least square,in which,the Momentum Theorem and the first law of thermodynamics were used to analyze the sensitive factors that influence the solar energy transmittance under the different flow states in the DSF and the porous media intermediate was adopted to simplified the bind in the DSF.
