摘　　要：利用有限元软件COMSOL Multiphysics对夏热冬冷地区不同朝向的泡沫玻璃外墙外保温系统在夏季时的温度场分布进行研究,计算结果表明,采用泡沫玻璃外墙外保温系统的墙体夏季外表面最高温度依次为西墙(48.9℃)>东墙(44.8℃)>南墙(40.0℃)>北墙(38.8℃),最低温度也呈相同趋势;泡沫玻璃具有良好的隔热性能,泡沫玻璃外保温系统具有良好的抵御夏季室外气温和太阳辐射综合热作用的能力。The temperature distribution of the external thermal insulation composite systems with foam glass was obtained using COMSOL Multiphysics software under different orientations in hot summer and cold winter areas during the summer.The calculation results show that the maximum external surface temperature of the ETICS-FG during summer is in the order of West Wall(48.9℃)>East Wall(44.8℃)>South Wall(40.0℃)>North Wall(38.8℃).The minimum temperature is basically the same;Foam glass has good thermal insulation performance,which has a good ability to withstand the combined effects of outdoor air temperature and solar radiation in summer.
