• Abstract:
  In cold regions, snow and ice cause serious safety problems to transportation systems. South central Alaska, particularly Anchorage, is susceptible to a number of icing
  
  events due to frequent freeze/thaw cycles in the winter season. Traditionally, deicing has been accomplished by mechanical, chemical, and thermal means. However, these
  
  methods suffer from one or more the following shortcomings: labor intense, damage to pavement, pollution in the environment, corrosion to vehicles and reinforcing steel
  
  in concrete, and high cost. A new type of deicing system that uses commercially available carbon fiber tape is proposed. This report presents the design of a deicing
  
  heating panel, the layout and construction of a test sidewalk, experimental results and analyses, and a cost comparison with other deicing technologies. Sixteen deicing
  
  and three anti-icing experiments were conducted in the winter of 2010–2011 to examine the performance and energy consumption of the proposed system. Experimental
  
  results reported include system performance, deicing time, energy consumption, deicing cost, and temperature variation with time and location. The sensitivity of the
  
  deicing unit to ambient air temperature, wind chill, and snow density is analyzed. Finally, this system is compared with other deicing systems in terms of annual operating
  
  cost, unit energy cost, and power density. The cost comparison shows that the proposed deicing system demonstrates higher energy efficiency than its competitors and has
  
  great potential for applications in cold regions. A provisional patent application has been filed on this new deicing technology.
