在民用建筑中,围护结构的保温设计是相当重要的部分,尤其是北方寒冷地区,围护结构的保温性能直接关系到建筑的质量、能耗和安全。因此,本文将于此讨论建筑围护结构在保温方面的机理和设计方法。建筑围护结构包括外墙、门窗、屋面三种,这三种结构是建筑散热、吸热、隔热的主要媒介,对建筑物整体的保温能效有重要意义。因此,有必要探析这些结构的保温机理,以此进行适当的保温设计,保证围护结构保温措施的有效性。
In civil buildings, the insulation design of the envelope is a very important part, especially in the cold northern areas. The insulation performance of the envelope is directly related to the quality, energy consumption and safety of the building. Therefore, this article will discuss here the building envelope in the insulation mechanism and design methods. Building envelope structure includes three kinds of exterior walls, windows and doors, roof, these three structures is the building cooling, heat absorption, heat insulation of the main media, the building insulation and energy efficiency as a whole is important. Therefore, it is necessary to explore the insulation mechanism of these structures, in order to carry out appropriate insulation design, to ensure the effectiveness of the envelope insulation measures.
