Abstract

We use a modular approach to develop a TRNSYS model for a district heating facility by applying inverse modelling to one year of operational data for individual components. We assemble the components into a single TRNSYS model for the full system using the accumulation tanks as a central hub connecting all other components. We compare predictions of the total heat delivered to the district heating network to observed values and find a model error of 7.1% for one simulation year.
