Abstract [en]

The aim of this survey is to explore different simulation software for designing of ground source heating systems. Models to simulate borehole storages, heat pumps, and system components like water storages, hydraulics and building loads are explored. This study is based on a literature survey of software and models for simulation of geothermal heating and cooling systems with focus on vertical ground heat exchangers. The study focus on the software used by the authors, which are EED, TRNSYS, Polysun, Modelica, IDA ICE, and Matlab/Simulink+Carnot.  The scopes and limitations of the software and models are evaluated and the advantages and disadvantages with the software are addressed.  It was found that the user-friendliness is strongly linked to the level of flexibility in the models. Higher flexibility usually means less user-friendliness and more time to learn the tool. EED, Polysun and IDA are considered to be the more user friendly softwares, while Modelica, TRNSYS and Matlab/Simulink+Carnot are considered to be the more flexible softwares. The models covering most of the aspects of borehole simulations are the TRNSBM-model in TRNSYS and the “INTERACT 2016” model for Modelica.
