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%。
In this paper, for the box house with the same composite phase change material and no composite phase change material, the variation of indoor air temperature and wall surface temperature is experimentally tested in the same outdoor climate. The results show that under the hot climate in summer, the composite phase change material can effectively control the indoor air temperature fluctuation and its rise in light building envelope construction; the maximum indoor temperature can be reduced by 8.5 ℃; secondly, at the low outdoor temperature Under the condition, the composite phase change material can release the heat absorbed during the daytime at night, which can increase the indoor temperature by up to 4 DEG C; in addition, the maximum energy saving rate of the air conditioner can reach 65.34% with the composite phase change material; the maximum energy saving rate of the heating reaches 77.27% .
