建筑围护结构传热系数的现场检测方法研究

Research on On-Site Testing Method of Heat Transfer Coefficient of Building Envelope

建筑节能是我国能源改革的重要领域,但是若想使建筑物传导的能量得到科学合理的控制,关键在于精准把握其围护结构的传热系数。基于此,论文首先介绍了现实中普遍应用的几种传热系数的检测方式,然后对国内外关于建筑围护结构传热系数的研究进行了论述分析,最后指出只有从实际出发,选用准确度高、测试时间短且对测试环境要求不高的传热系数检测方法,才有助于我国建筑节能工作落到实处。

Building energy saving is an important field of China's energy reform,but the key to the scientific and reasonable control of the energy transmitted by the building is to accurately grasp the heat transfer coefficient of its envelope.Based on it,this paper first introduces several testing methods of heat transfer coefficient which are widely used in reality,then discusses and analyzes the research on heat transfer coefficient of building enclosure structure at home and abroad,and finally points out that only from the actual situation,the method of measuring heat transfer coefficient with low measuring precision, short test time and low requirement to test environment will be helpful to the construction energy saving work in our country.
