摘要
建筑物为了节约能源消耗,当室内和室外的温度差异较大时,需要尽可能的阻止室内与室外的热量交换,以便把室内的环境温度维持在一个稳定而且舒适的范围内。外墙外保温和内保温相比,从表面上看,只是把保温材料从一个面移到了另一个面,如果但从一个简单的面积传热的角度来看,这样的改变对传热效果并没有什么大的改变,但从一个整体建筑物的角度看,外保温和内保温两种做法改变了对建筑物包覆程度和包覆效果,正是这种差异导致了保温效果的较大差异。本文就当前我国常用的外墙保温技术及通过实例计算、分析、对比说明了外墙外保温和内保温的差异,在大力推广外墙保温技术的同时,加强新型节能材料的开发和利用,从而使建筑节能真正得以实施。
In order to reduce energy consumption of buildings, when the indoor and outdoor temperature differ greatly, it is necessary to prevent the heat exchange between indoor and outdoor to keep the indoor temperature at a stable and comfortable range. Compared to internal insulation, the insulation material is moved from one surface to another surface. If only from a simple point of view of heat transfer, such a change has no effect on heat transfer, but from the perspective of whole building, the exterior insulation and thermal insulation change the level of the building cladding and coating effects. It is this difference that has led to large differences in the effect of thermal insulation . In this paper, The differences in internal and external insulation of exterior wall are discussed based on the commonly used technology on the exterior wall and calculation, analysis, comparison. While promoting thermal insulation technology of external walls, we should enhance the development and utilization of new energy- saving materials to implement energy- saving of construction.
