Abstract
Borehole thermal energy storages can be implemented anywhere on Earth, regardless of existing geological conditions. The differences lie only in the number of drilling boreholes necessary to drill. In places where there are rocks with high thermal conductivity or these are wet layers, and additionally with filtering underground water, greater power (energy efficiency) of a single borehole heat exchanger is achieved. Additionally, larger amounts of heat can be stored. Groundwater flows may have a beneficial or adverse effect on heat and/or cold storage. Large fields of borehole heat exchangers enable maintaining thermal comfort in large buildings. The use of geothermal/ground heat pumps is the most advantageous way to meet the heating and air conditioning needs in buildings from an energy point of view. Geothermal/ground heat pumps have the highest efficiency among heating and heating and cooling boilers/devices. Compared to air source heat pumps, they use and/or store driving energy from a power plant, in the case of compressor heat pumps. Higher efficiency can have only water heat pumps, which use underground or waste waters. It can be concluded that the more borehole exchangers, the more advantageously the heating or heating and cooling system will operate in terms of operating costs. Their main component is the cost of driving energy for heat pumps (compressors). The energy needed to force the circulation of the heat carrier in borehole heat exchangers is less important. The paper presents issues related to ensuring adequate hydraulic power, which is particularly important in larger heating and heating-cooling installations based on borehole exchangers and geothermal/ground heat pumps.
