Life Cycle Energy Consumption of Retaining Structure of Mongolian Yurt

从毛毡材料入手,对传统羊毛毡材料进行热工性能分析。将传统蒙古包建筑厚度为18 mm毛毡的导热系数、传热系数进行数据分析处理后的平均导热系数为0.076 6 W/m·K,传热系数平均值为1.39 W/m^2·K。通过对其进行精细化试验分析,将羊毛、棉花、PVA纤维三种材料混合配比,经数据分析处理后羊毛棉花、羊毛PVA纤维、棉花PVA纤维的平均导热系数分别为0.059、0.066、0.075 W/m·K。从而解决了全寿命周期内围护结构材料耗能量高的重要问题,实现优化后热指标高于优化前6 W/m^2左右,促进、提高了毛毡材料的节能保温性。

Starting with blanket materials,the paper analyzes the thermal performance of traditional wool felt material. The average thermal conductivity is 0. 0766 W/m·K and the average heat transfer coefficient is 1. 39 W/m^2·K. The thermal conductivity of the traditional yurts is 18 mm. The average thermal conductivity of wool fiber, wool PVA fiber and cotton PVA fiber were 0. 059,0. 066 and 0. 075 W/m·K respectively after analyzing the data by the mixing ratio of wool（ wool,cotton and PVA）,which solves the high energy consumption of the envelope material in the whole life cycle,so as to realize the optimization of the thermal index,enhancing the thermal index 6 W/m^2 by optimization,which promotes and improves the energy efficiency of the felt material.
