Technique and Analysis of Snow-Ice Melting System on Road by Thermal Energy Storage

A snow-ice melting system on the road by thermal energy storage will become a sustainable and important measure in the transportation of the future by reason of the contamination of nature environment from chemical deicing/snow melting agents.Recently thermal snow-ice melting technologies are expected to be come more prevalent.Usually thermal snow-ice melting system can be classified into three kinds,conductive concrete/asphalt,electrically heating cable and hydronic snow-ice melting system.Furthermore the hydronic snow-ice melting system can lead to the utilization of the renewable energy and the thermal energy storage(TES),such as geothermal energy,solar energy,earth energy and so on.This system can reach a highest efficiency and lowest pollution.Now a snow-ice melting system on the road by TES has been recognized as a green technology with better prospect and sustainable development.The status and progress of snow-ice melting with TES in the world are summarized and the basic problems for development in the future are emphasized.Investigation of these problems will strengthen theoretical understanding and facilitate the application,especially in China.
