摘要
简要介绍当前建筑节能现场检测方法存在的问题和不足,在一维稳态传热理论基础上,建立了传热系数与围护结构外表面温度的数学关系,提出采用红外热像仪检测围护结构传热系数的操作方法,并通过实例进行验证,以期对围护结构的现场检测问题的解决提供帮助。
Brief presents the current the construction conservation energy field test method has many questions and the insufficiency.basing on one-dimensional steady state heat transfer theory,has established mathematical relationship between the heat transfer coefficient and temperature of the outer surface of building envelope constructions,Proposes the operating procedure that uses infrared photography examination building envelope constructions heat transfer coefficient,And carries on the confirmation through the Specific example,Provides the help about solving building envelope constructions＇ field test question.
