耐候实验中外墙外保温系统的内部湿热特性分析

Analysis of Internal Humid Heat Properties of External Thermal Insulation System of Exterior Wall in the Weathering Test

外墙外保温是建筑围护结构节能的主要方式。在外保温系统内部布置温度和湿度传感器,采集外保温系统在耐候性试验中内部温湿度的变化数据进而分析了保温系统的湿热特性。结果表明采用不同的保温材料,系统内的湿度变化规律不同;EPS保温系统保温层两侧的温度变化幅度显著。

External thermal insulation of exterior wall is the primary way of energy conservation of building envelopes.Temperature and humidity sensors are installed in the interior of the external thermal insulation system to collect the data of the change in internal humiture of the external thermal insulation system in the weathering test and then analyze humid heat properties of the thermal insulation system.It turned out that the laws of the change in humidity in the system are different for different thermal insulation materials;and the temperature of both sides of the insulating layer of the EPS thermal insulation system varies within a wide range.
