碳纤维带电热地暖性能的足尺试验研究

设计了一套基于碳纤维带电热技术的地暖系统,并对其供暖性能和经济适用性进行了研究.选取一间保温隔热良好的卧室铺设该地暖系统,并预先在地板各层、近地表空间布置多个温度传感器.进行24h供暖试验,通过检测和分析设定位置的温度变化来研究该系统的性能和能耗.结果表明:碳纤维带电热地暖能够将室内温度保持在设定范围内,合理布置碳纤维带可以将各层横向温差控制在3℃以下.通过与传统采暖方式间的造价及运行成本的对比,研究了碳纤维带电热地暖的经济适用性,发现碳纤维带电热地暖具有造价费用低、运行费用适中、总费用低的优势.

Full-scale Experimental Study on the Performance of Electrical Floor Heating Utilizing Carbon Fiber Tapes

An electrical floor heating system was designed by using carbon fiber tapes (CFT). The heating performance and economic applicability of the heating system were also analyzed. The heating system was constructed in a bedroom with good heat insulation, and the temperature sensors were arranged at the layers of the floor and near the floor for 24 h duration tests. Temperatures at specified locations were monitored and analyzed to study the performance and the energy consumption of the heating system. The results showed that the CFT electrical heating system could keep the indoor temperature constant within the preset range; the temperature gradient in lateral direction was within 3 °C when the carbon fiber tapes were reasonably arranged in the floor. Meanwhile, compared with that of the traditional heating methods, the economic applicability of the proposed heating system was also studied. The results show this CFT electrical heating system has the advantages of less construction cost, medium operation cost and less overall cost.
