Ground heat exchangers—A review of systems, models and applications
TL;DR: In the literature, several calculation models are found for ground heat exchangers as discussed by the authors, which can accommodate for any type of grid geometry that may give greater detail of the temperature variation around the pipes and in the ground.
Journal ArticleDOI
Current status of ground source heat pumps and underground thermal energy storage in Europe
TL;DR: Geothermal heat pumps as mentioned in this paper use the earth as a heat source when operating in heating mode, with a fluid (usually water or a water-antifreeze mixture) as the medium that transfers the heat from the earth to the evaporator of the heat pump, thus utilising geothermal energy.
