Modelling Ground Collectors and Determination of the Influence of Technical Parameters, Installation and Geometry on the Soil

The main objective of this work was to model ground collectors with different parameters and geometries in ANSYS R19.2 and to simulate their operation during the heating season in Slovakia in order to determine their impact on the soil. At the same time, four new geometries in the shape of vertical...
