摘要

木结构墙体稳态热量传递性质是评价其节能保温的重要指标.为了在引进国外木结构住宅先进技术基础上

推进轻型木结构住宅国产化进程

该研究使用国产材料制备了13块不同构造的轻型木结构墙体

采用热箱－热流计法检测了稳态时墙体的有效传热系数

并通过理论计算

得到了各墙体的理论计算预测值.结果表明

墙体有效传热系数在0.226～0.529 W/(m2· K)之间

除热工级别为IIt级的1、2、3、6号墙体外

其它墙体均为It级

完全适用于中国严寒地区

并满足中国节能65%的墙体传热系数限值要求.通过理论计算预测传

Abstract

Steadystate heat transfer performance is an important indicator for wood wall to assess its energy efficiency performance. Based on the introduction of foreign advanced technology of wood residence

13 different wall specimens were manufactured using domestic materials in this study

and the effective heat transfer coefficient were measured by hot boxheat flow meter test method. With the results from theoretical calculation

it was found that the effective heat transfer coefficient of walls were between 0.226～0.529 W/(m2· K). The thermal level was IIt for specimen 1

and 6

and level It was for the others

which could be appropriate for the severe cold areas and meet the requirements of 65% Energy efficiency standard in China. The calculation results were in good agreement with the measured ones.
