多孔砖夹芯复合墙热工性能分析

Analysis on the thermal property of composite wall sandwiched with porous brick

本文对寒冷地区节能65%标准的居住建筑,采用多孔砖夹芯墙保温时,在采暖期内墙体各层界面的温度变化、水蒸气渗透、露点温度、高湿结霜、热桥部位最小传热阻以及夏季隔热等问题进行了热工性能分析,证明夹芯复合墙保温隔热性能良好,室内温差小,热环境舒适度高,耐侯性强,是多层砖混采暖建筑外围护结构的首选方案。

Analysis on the thermal properties of composite wall sandwiched with porous bricks was carried out on the base of energy saving 65% civil constructions. Results showed that composite wall was the first choice with good thermal insulation, small temperature difference between inner and outer, comfort environment and high weather resistance.
