摘    要:为减小污染和电网峰谷差,提出了一种利用定形相变材料(PCM)蓄存夜间廉价电热的地板电采暖系统,研究了此定形PCM的热性能,搭建了应用此采暖系统的实验房间,测量了系统和室内空气的温度变化,分析了此采暖方式的使用效果。结果表明,此系统的热性能较好,白天的电热负荷转移到了夜间低谷电价时段,在实行峰谷电价的地区,可以节省电费,同时使室内温度分布均匀,是一种节能舒适的采暖方式。

Abstract:A new kind of shape-stabilized phase change material (PCM) was developed, with which a novel under-floor electric heating system was manufactured. This system can charge heat by using cheap nighttime electricity and discharge the heat stored at daytime, with the merits of decreasing city's air pollution and electricity load. In the present work, the thermal physical properties of the shape-stabilized PCM were measured. A prototype room with this system was set up in Beijing to study its thermal performance. The experimental results testify the feasibility and comfort of the heating mode and show that a lot of off-peak period electricity can be used for space heating instead of using peak period electricity, which obviously lowers the electricity tariff and makes indoor temperature uniform.
Keywords:shape-stabilized PCM  thermal storage  under-floor electric heating system
