Effects of the District Heating Supply Temperature on the Efficiency of Borehole Thermal Energy Storage Systems

The mismatch of high heat demand in winter and high solar heat supply in summer can be compensated by solar district heating (SDH) with borehole thermal energy storage (BTES) systems. Transient simulations are imperative to attain a good understanding of the system behavior and to determine an optimized system design. In this context, the models of SDH systems and BTES pose very different requirements on their simulation environments. Taking...
