竹结构建筑外墙热工性能测试与分析
|
摘要
为了对已建成竹结构建筑外墙的热工性能进行评价,采用控温箱-热流计法对现代竹结构抗震安居房外墙(抹灰和挂板两种饰面)传热阻进行了实测与分析。结果表明:控温箱-热流计法测试竹材墙体传热阻时误差较大,影响墙体传热阻的主要因素为竹材墙体内部结构组成及测试位置;抹灰饰面外墙平均实测传热阻为1.52(m2.K)/W,传热系数为0.66 W/(m2.K),可应用在夏热冬冷、夏热冬暖地区,4层及以上建筑可达到节能65%标准;挂板饰面外墙平均实测传热阻为2.71(m2.K)/W,传热系数为0.37 W/(m2.K),可以应用在夏热冬冷、寒冷地区和严寒地区,并达到节能65%的标准。
In order to evaluate thermal insulation performance of external wall of bamboo structure,an experimental study on the thermal performance of external wall(its facing includes plastering and hanging plate)in built modern bamboo structure anti-seismic welfare housing was conducted,using the measurement of temperature controlled box-heat flow meter.The results showed that the main influence factors in testing the thermal performance of bamboo walls with temperature controlled box-heat flow meter were the structure of bamboo walls and the measuring position.For external wall with plastering facing,the average value of the heat-transfer resistance was 1.52(m2·K)/W,while the value of the heat-transfer coefficient was 0.66 W/(m2·K);and for external wall with hanging plate facing,the average value of the heat-transfer resistance was 2.71(m2·K)/W,while the value of the heat-transfer coefficient was 0.37 W/(m2·K).This two kinds of bamboo walls had excellent properties of insulation and energy saving.The external wall with plastering facing,which achieved the standard of saving 65 % energy partially,could be used in hot summer and cold winter,hot summer and warm winter area.The external wall with hanging plate facing,which achieves the standard of saving 65% energy,could be used in hot summer and cold winter area,hot summer and warm winter area and cold area.
