摘要:
为研究相变石膏板围护结构在过渡季节的储热性能,搭建了两间尺寸相同的实验对比房,将相变石膏板贴敷于围护结构内侧,测试对多种工况下实验对比房的室内温度及壁面温度,通过房间热性能分析探讨其在过渡季节的适用性。石膏板中的相变微胶囊以石蜡(正十八烷)为芯材,聚甲基丙烯酸甲酯(Polymethyl methacrylate,PMMA)为壁材,相变温度28 ℃,相变潜热180 kJ/kg。在相同的室外气候条件下,进行一个月的多组工况实验研究,测试了室内空气温度和墙体表面温度的变化规律,并与普通房间进行了室内热环境对比分析。结果表明:相变石膏板热性能稳定;在杭州地区过渡季节最高可降低室内峰值温度1.10 ℃,减缓壁面温度波动1.18 ℃,延迟峰值时间40 min,降低室内温度不舒适度6.82 ℃·h/d,有效缓解了室内的温度波动,增强了围护结构的热惰性。此外,与夜间自然通风相比,相变围护结构在夜间通风的情况下可以减少室内不舒适度时间约2 h,减少累计室内温度不舒适度2.08 ℃·h/d,有效提高室内热舒适性。该研究通过对比实验验证了相变石膏板应用于围护结构的隔热效果,可为后续模拟研究提供参考。
