    摘要:

    根据空心砌块的频域热特性辨识其s多项式传递函数,并进一步求取空心砌块的CTF系数。根据空心砌块动态热特性实验结果对采用CTF系数计算空心砌块热特性的可靠性进行了验证。结果表明,在边界条件趋于周期性稳定后,采用CTF系数和实验得到的空心砌块内外表面温度曲线非常吻合。因此,CTF系数能准确的计算空心砌块的动态热特性,是一种分析空心砌块动态热特性的有效方法。

    Abstract:

    The s-polynomial transfer function of hollow blocks is obtained from the theoretical frequency characteristics, and the Conduction Transfer Function (CTF) coefficients of the hollow block are derived from the identified s-polynomial transfer function. The dynamic thermal experimental results of a hollow block are used for validating the results by using the CTF coefficients. The comparison shows that the surface temperature of the hollow block calculated by using the CTF coefficients agrees well with the experimental results after the boundary condition tends to be periodically stable. The results further show the identified s-polynomial transfer function as well as the resultant. CTF coefficients can represent accurately the dynamic thermal characteristics of the hollow block. CTF coefficients is an effective approach for analyzing the dynamic thermal characteristic of hollow blocks.
