【摘要】 随着发展低碳经济和建设节约型社会日益受到重视,节能减排也成为社会关注的热点。而建筑节能又是节能减排的一个重要领域,发展空间巨大。由于我国建筑节能起步较晚,许多建筑没有做节能措施或措施不到位,需要对其进行节能诊断,为建筑的节能改造提供依据。对于新建建筑往往由于施工或设计的不合理,会产生一些围护结构的热工缺陷,导致保温、隔热效果不能达到要求,此时也需要对其进行节能诊断,判断节能效果是否满足要求,指导建筑的设计和施工等。目前,建筑节能检测和诊断有许多方法,红外热像技术是其中最为简单、直接、方便的。本文主要介绍红外热像技术的原理和在建筑节能诊断中的应用,结合现场检测的温度分布情况,对测量建筑进行热工分析和节能诊断,判断其节能效果。更多还原

【Abstract】 With the development of low carbon economy and build a conservation-oriented society more and more attention,energy conservation has become the focus of social concern.Building energy efficiency is an important area of energy saving,have huge space for development.China’s building energy efficiency as a late start,many buildings have not or are not in place energy saving measures,need energy-saving diagnosis,provide the basis for construction of energy-saving.As for the new building construction or design are often unreasonable,will produce some thermal envelope defects,resulting in insulation,thermal insulation does not meet the requirement,at this time also need their energy-saving diagnosis,determine whether the energy savings to meet the specifications guide the design and construction of buildings and other.Currently,detection and diagnosis of building energy efficiency in many ways,but the infrared thermal imaging technology is one of the most simple,direct and convenient.This paper introduces the principle of infrared technology and application in building energy efficiency diagnostics,combined with the temperature distribution in the detection of measurement,analysis and judgement its building energy efficiency effect.更多还原
