摘　　要：本文针对安装有复合相变材料与没有复合相变材料的尺寸完全相同的箱体房,在相同的室外气候条件下,实验对比测试了室内空气温度和墙体表面温度的变化规律。结果表明,在夏季炎热的气候条件下,复合相变材料能够有效地控制轻质围护结构建筑室内空气温度的波动及其上升;最大可降低室内温度8.5℃;其次,在室外气温较低的情况下,复合相变材料在夜间能把白天吸收的热量进行释放,最大可提高室内温度4℃;此外,采用复合相变材料可使空调最大节能率达到65.34%;供暖最大节能率达到77.27%。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 hot summer climate conditions, composite PCM could effectively control fluctuation and rise of indoor air temperature of lightweight envelope buildings; maximum indoor temperature could be reduced to 8.5℃ ;secondly,in the case where outdoor temperature was low, composite PCM could during the night release its heat received at daytime,and could increase a maximum indoor temperature of 4℃;In addition, use of composite PCM could cause energy saving rate of air conditioner to reach 65.34% ;maximum energy saving rate of heating could reach 77. 27%.
