摘要:基于热四端网络法的瞬态响应模型,建立了建筑围护结构表面脉冲信号和阶跃信号瞬态响应与围护结构内部材料蓄热系数之间的数学表征关系,提出了通过施加上述2种信号分析围护结构表面瞬态响应数据来获取材料蓄热系数的无损检测方法。针对随机信号引起的瞬态响应数据,基于杜哈梅尔定理,采用反卷积法和截断奇异值分解法,提出了重建脉冲信号响应和阶跃信号响应的数值方法,突破了实际现场检测时对围护结构输入信号的限制。采用上述方法对2种建筑材料进行了检测实验,结果表明,利用该方法可以准确快速地对建筑材料的蓄热系数进行定量检测。

Abstract: The relationship between the surface transient response of pulse and step signals of the building envelope and the heat storage coefficient of the envelope materials is established based on the thermal quadrupoles model. A non-destructive diagnosis method is proposed to obtain the heat storage coefficient of the envelope materials by applying the above two kinds of signals to analyse the surface transient response data. Based on the Duhamel theorem, a numerical model of reconstructing pulse and step signal responses using the transient response data from random signals is proposed by deconvolution and TSVD(truncated singular value decomposition) methods, which breaks the limitation of input signals during the actual diagnosis. The experiments on two typical building materials are carried out to verify the method. The results show that the heat storage coefficient of building materials can be diagnosed accurately and quickly by using this method.
