abstract

An automatically controlled hydronic ice-snow melting (HISM) technology in road coupled with slab solar collection (SSC) and underground thermal energy storage (UTES) has become an increasingly sustainable and important measure in road engineering and heat engineering An experiment on the hydronic snow melting system with coil pipe imbedded in road was implemented to investigate the thermal characteristics of simultaneous snow and melt in road. Research focused on the active sync process of road snow melting in the different pitch pipe, snow melt patterns, surface temperature, unit area heat consumption and unit length temperature difference, etc, and explored factors of impact characteristics, and recognized a synchronous process. The result shows that the smaller pipe pitch of dense arrangement is, the higher snow free area ratio is and the effect of snow removal is better. Actually the short duration of snow melting needs big heat load and heat consumption. The arrangement of small pitch can support big heating intensity. In the simultaneous snow and melt, a short duration of snow melting and timely melting must be fulfilled as quickly as possible and it can significantly shorten the lifetime of snow accumulated on road. But a big heating system will be required and it leads to a large initial investment.
