Power Analysis on Deicing and Snow Melting by Electrically Conductive Concrete

分析了目前常用除冰化雪方法的利弊 ,介绍了导电混凝土电热除冰雪的工作原理 ;从能量守恒的角度分析了导电混凝土电热除冰雪的最低功率需求 ;实验测试了碳纤维混凝土电热功率与电压的关系 ,表明碳纤维混凝土通电后产生的热量能够满足冬季路面除冰化雪的需要。

The deicing and snow melting methods frequently used and their advantages and disadvantages are analyzed at first, then the working principle on deicing by electrically conductive concrete is introduced. Based on the energy conservation law, the minimum power required for deicing and snow melting is determined. The curve of power output versus voltage of carbon fiber reinforced concrete (CFRC) is measured in laboratory; the experimental results show that the thermal energy produced in CFRC connected to DC power source is enough for deicing and snow melting purpose.
