外墙外保温系统对室内热环境的影响

Impact on Hot Environment of External Insulation System for Exterior Wall

采用对比试验的方法,建立采用外墙外保温系统的试验房间和不保温的对比试验房间,利用自动数据采集系统连续采集两房间不同部位的实时温湿度,分析外墙外保温系统的隔热保温性能。试验结果显示,外墙外保温系统具有优异的隔热保温性能。在相同的空调温控设定条件下,采用外保温的房间室内温度基本不受外界温度变化的影响。保温房间室内温度分布均匀。使用外墙外保温系统能营造良好的室内热环境。

The quantity of heat insulation and preservation of External Insulation Finish System (EIFS) was e-valuated through a contrasting test in two separated rooms with or without EIFS. Testing data were collected by a computer program on real time.The results show EIFS have an outstanding performance in its quality of heat insulation and preservation. The indoor air temperature of EIFS room maintains relatively constant under the control of an air-conditioner and cannot be affected by outdoor temperature's change.The indoor temperature field is relatively even.
