Abstract

BRIDGESIM is a dynamic simulation programme for the assessment of the thermal performances of a bridge heating for ice prevention with solar heat stored in a seasonal ground duct store. Solar gains are collected with the bridge during summer and stored in the ground. Heat is recovered from the ground during winter to unfreeze the bridge. Long-term effects, which can be determinant in correctly sizing such a system, can be simulated for up to 50 years. A user-friendly interface allows the user to define the parameters relative to his particular problem. BRIDGESIM requires meteorological data in input as well as the bridge structure data. The bridge input data file is generated with the demo version of the TRNBuild programme of the TRNSYS package. BRIDGESIM has been developed using the project in Serso – Därlingen in the Swiss Bern county and has been calibrated with 2 years of detailed monitoring.
