新型竹结构建筑传热特性
|
摘要
竹材具有生长周期短、产量高、强度高、环保及可再生等特点,作为现代建筑材料已经越来越受到人们的重视。本文在自然气候条件下,通过在墙体内各个界面预埋热电阻Pt100,对竹结构实验用房这种新型墙体温度进行实测,结合竹材自身的热物性参数特点和墙体(多孔介质)传热机理,分析其温度分布规律,研究竹结构动态传热特性,以期为现代竹结构建筑传热特性的研究提供一些基本数据,为科学设计、分析竹结构建筑的传热特性提供依据。结果表明,竹结构建筑具有良好的隔热保温性能,对节能具有重要的意义,利用竹材作为现代建筑材料符合可持续发展的要求。
Bamboo has the future of short growth cycle,high yield,high intensity,environmental,renewable,etc,and as a modern building material has become increasingly attention has been paid.In this paper,under the natural climate conditions,through buries thermal resistance Pt100 in each contact surface of the wall,testing the wall temperature of bamboo structure experimental house,combined with bamboo thermal parameters characteristics and the wall(porous medium) heat transfer mechanism to analyze the temperature distribution rule and research the dynamic heat transfer characteristics of bamboo structures,for the heat transfer characteristics of modern bamboo structure architectural research to provide some basic data,as well as for future scientific design and analysis of the heat transfer characteristics of bamboo structure architectural provide the basis.The results indicate that the bamboo structure architectural has the good thermal insulation performance and has the vital significance to the energy conservation,using the bamboo as the modern building materials meet the sustainable development requirement and bamboo is an ideal building material.
