摘要
本文以长春市某实际公共建筑为例,现场测试粉煤灰蒸压加气混凝土外墙的传热系数,将测试值与理论计算值、《公共建筑节能设计标准》(GB50189-2005)规定的外墙传热系数上限值进行对比分析,得出粉煤灰蒸压加气混凝土自保温围护结构外墙完全满足节能标准要求,不必附加保温材料的研究结论.并进一步以外墙测试传热系数和节能标准规定上限传热系数为主要参数,用DeST-c软件模拟计算其建筑能耗.模拟计算结果显示,采用粉煤灰蒸压加气混凝土自保温围护结构的公共建筑采暖能耗比节能标准要求低16.32%,具有显著节能性.
This article to Changchun a actual public building for case, scene test fly ash steamed pressure plus gas concrete outside wall of heat transfer coefficient, test value and theory calculation value, and the upper value of design standard for energy efficiency of public building （ GB50189 -2005） for contrast analysis, concluded that fly ash steamed pressure plus gas concrete since insulation enclosure structure outside wall full meet energy -saving stand- ard requirements, having to additional insulation material of research conclusions. And further test the wall heat transfer coefficient and energy - saving standards for maximum heat transfer coefficient for the main parameters, whose energy consumption is calculated using DeST - c software simulation, simulation results show that using auto- claved aerated concrete thermal insulation of exterior - protected structure of heating energy consumption of public buildings 16.32% lower than the energy - saving standards, with significant energy saving.
