建筑节能现场传热系数间接检测法及其影响因素分析

On-site Indirect Testing Method for Heat Transfer Coefficient for Building Energy-saving and Analysis of Its Influencing Factors

现场对建筑物进行耗热测试时,直接法测试受到必须在采暖期进行的限制,间接法测试虽不受此限制,但外界因素的不确定性也一定程度影响了其使用。经过实验提出了在我区使用间接法进行测试的条件,其精度达到了规定之要求,证明它是建筑物耗热测试的一种简便、快捷、可行的方法.

For the on--site test of heat consumption of buildings, the direct method c only during the heating supply period. Although the indirect method is not subject to t an be used his limitation, the uncertainty of external elements will affect its application to some extent. Conditions for the test using the indirect method in Inner Mongolia area are put forward through experiment, under which the test accuracy meets the requirements of the code. It is proved that the indirect method is a simple, quick and feasible method for the test of heat consumption of buildings.
