Energy Geostructures in Cooling‐Dominated Climates
This chapter presents an overview of the impact of climatic factors on soil conditions, and the associated energy geostructures' performance in different soil types and situations. Geothermal energy systems in cooling‐dominated climates work by circulating hot fluid in pipes, and relying on a temperature gradient to inject heat into the soil. Climatic factors impact soil conditions in the shallow soil layer (SSL), especially the soil saturation profile. Heat transfer in soils can take place by conduction, convection and radiation. A change in soil conditions will impact the structural capacity and overall thermodynamic performance of energy piles. To study the behavior of an energy pile at a certain depth and a given soil condition, laboratory tests were performed on a soil‐energy pile planar section in sand. The laboratory tests were then numerically modeled to evaluate the heat exchange rate between the soil and energy pile.
