摘　　要：测定2019年9月初沈阳某玻璃幕墙室内表面温度和室内空气温度,并据此得出玻璃幕墙室内各表面温度的分布规律及其随时间的变化情况,其中与地面接触的型材表面温度受到室外环境影响比其他部位型材更明显。使用现场实测数据和规程提供的边界条件,在MQMC软件上建立模型,得出玻璃面板、立柱和横梁的表面温度。对比发现,表面温度数值模拟结果与现场实测结果接近。通过对玻璃幕墙表面温度实测和模拟,为提高玻璃幕墙保温隔热性能提供参考依据。The indoor surface temperature and air temperature of a glass curtain wall in Shenyang are tested in early September 2019,the variation of indoor surface temperature of the glass curtain wall and how it changed with time are obtained.The surface temperature of the profile contacting with the ground is affected by the outdoor environment more obviously than that of the profile in other parts.Then using both the measured data and boundary conditions,the models are established on MQMC,surface temperature of the glass panel,columns and beams are obtained respectively.It is found that the numerical simulation results of surface temperature of the glass curtain wall are close to the field measurement results.Through the measurement and simulation of the surface temperature of the glass curtain wall,it provides a reference for improving the thermal insulation performance of the glass curtain wall.
