Soheil Porkhial,Omid Asgari,Mohammad reza Shirzadi E-mail: Porkhial@yahoo.com asgari@mehr.sharif.edu mrshirzad i@sina.kntu.ac.ir Abstract A geothermal snow melting system consists of hydronic tubes embedded in critical points of roads,highways and bridges.A fluid can be heated by using a ground source heat pump system(GSHP) and circulated through the embedded pipes to prevent freezing condition on the surface. The goal of this paper is to find practical techniques to decrease operation time of heat pumps to saving energy. This paper consists of a ~D parametric simulation of a typical bridge with considering the weather of Tehran. This simulation contains different parametric inputs like physical properties and geographical conditions.One important characteristic of this paper is considering .different layers and materials in the bridge
