摘 要:
本文利用红外热像仪来测定建筑围护结构中是否存在热工缺陷。在不破坏围护结构的前提下,通过测试缺陷部位表面温度及热工缺陷面积两项指标,确定节能建筑是否存在热工缺陷。测试结果表明,红外热谱图可以正确地反映建筑结构表面的温度场分布,从而判断围护结构是否存在热工缺陷。用热像仪检测节能建筑是否存在热工缺陷,为建筑节能效果的评价提供了高效、准确的检测手段,有助于全面开展建筑节能检测。[著者文摘]

Abstract:
The infrared thermography was used to estimate the thermodynamic disfigurement in this article. The experiment shows that infrared spectra can correctly provide the temperature distribution of the structural surface, which helps solve the problem of the judgement of the thermodynamic disfigurement. At the same time, under the premise of undestroying the envelope structure, from the surface temperature and the area of the thermal detection we can determine whether the thermodynamic disfigurement of the energy - saving building exist or not. This new method provides a highly efficient and accurate means of detection, which will conduce to the comprehensive testing of the energy conservation.[著者文摘]
Key words:
envelope structure; thermodynamic disfigurement; infrared thennography; building energy conservation
