DEVELOPMENT OF A HOT WATER PANE HEATER TYPE SYSTEM FOR MELTING SNOW ON SIDEWALKS

Conventionally, in cold regions covered with snow in winter, it was difficult to secure safe sidewalk spaces for pedestrians because of the amount of snow from the roadways and the roofs of private houses piled on them. The sidewalk snow melting systems currently in use consist of the same sprinkling method, electric heater method and hot water pipe method used to melt snow from the roadways. These conventional systems pose problems such as low service level because of puddles formed on sidewalks, high running costs, and the difficulty of securing installation space in urban areas. Ministry of Land, Infrastructure and Transport and local governments, in accordance with "Transportation Barrier-Free Law", are moving to provide snow melting systems in order to secure sidewalk spaces in city centers around public institutions and so on. Furthermore, while moving to reduce the total cost of the snow melting systems, these entities are actively working to develop snow melting systems that effectively utilize non-conventional energy and natural energy. To respond to these requirements, this paper utilizes the sheet steel hot water panels that were successfully used on railways in 1992. to develop a hot water panel snow melting system for sidewalks that employed non-conventional energy in the form of low-temperature heat sources such as sewage heat and the exhaust heat from cities. The paper describes the benefits and requirements for applying hot water panels to sidewalks.
