Dynamic Simulation Of Bidirectional Low-Temperature Networks - A Case Study To Facilitate The Integration Of Renewable Energies

Building Simulation Conference proceedings, vol. 16, pp. 3491–3498

Abstract

The global climate targets lead to a growing interest in supplying buildings with heat and cold more efficiently. In districts with simultaneous heating and cooling demands, bidirectional low-temperature networks can be an efficient alternative to balance local demands within one thermal network. In order to examine this concept in more detail, this paper presents an integral dynamic simulation model of a bidirectional low-temperature network with 15 connected buildings, equipped with heat pumps and chillers in Modelica. Performing different simulation studies regarding temperature levels of the system as well as storage utilization and the integration of renewable energy sources, the general benefits and barriers of this innovative concept are evaluated.
