摘要
主要从现场测试角度验证系统辨识方法在建筑墙体传热系数动态测试的适用性。以普通建筑外墙为例,采用温控箱测试装置进行实验测试,利用现场实测数据并运用最小二乘递推算法对这种墙体的传热系数进行了辨识。
It validates the system identification method in dynamic test for overall heat transfer coefficient of building wall from the perspective of the in-site test.Taking a type of ordinary exterior wall for example,temperature-controlled box is utilized to test,identifying the overall heat transfer coefficient of building wall with measured data and recursive least squares algorithm.
