摘要
为了分析冬季工况下相变材料对轻质建筑室内热环境的调节性能,通过搭建两相同尺寸的箱体实验平台,在箱体的室外气候条件下,实验对比测试了两箱体的室内空气温度、墙体表面温度和墙体热流量变化规律并且分析了不同天气情况下的变化规律。结果表明,晴天,相变材料能够明显的降低轻质建筑室内温度的波动,增强房间的热稳定性,特别是在夜间对于室内空气温度将有较大的提高,最大达4℃;阴天,将相变材料应用在轻质建筑中的作用不是很大,只是相当于增加墙体的厚度,对室内热环境的改善意义不大;应尽量将相变材料在多云晴朗太阳辐射量大的地区使用,充分发挥其储热和放热的功能。
In order to study on Light Weight Building Envelope with Phase Change Material for Indoor Thermal Environment Adjustment In W＇mter, this paper tested under the same outdoor climate conditions change rules of indoor air temperature and wall surface temperature of cabinet rooms with the same size where composite PCM was installed and composite PCM was not installed through experimental comparison. The results showed that, under sunny day climate conditions, PCM could effectively control fluctuation and rise of indoor air temperature of lightweight envelope buildings. Especially at night, maximum indoor temperature could be increased to 8.5℃. Under cloudy day climate conditions, PCM to improve indoor thermal environment is very limited, only the equivalent of increasing the thickness of the wall. PCM should be used in large solar radiation areas. It can play heat storage and heat release function.
