摘要
通过对铝合金建筑隔热型材热性能指标(传热系数)、实验原理、标定程序及实验程序等进行研究,提出了隔热型材传热系数的测定方法—热箱法,并将该法的测定结果与计算机模拟结果进行了比较.结果表明:计算机模拟数值比本法的实测值略小;经不同实验室及不同实验条件下验证,本方法具有较好的复现性和可比性.
By means of the study of performance index（thermal transmittance）,experiment principle,calibration procedures and experiment procedures for wrought aluminium alloy extruded thermal barrier profiles for architecture,the determination method for thermal transmittance of thermal barrier profiles-hot box method is came up with,and the determination values by this method are compared with the simulation values by computer.The results show that：the simulation values by computer are smaller than measured values by this method;this method is appropriately validated good reproducibility and comparability under different labs and different conditions.
