The Power of a Sustainable Future, Hidden in the Depths of the Earth

Testing the effective thermal conductivity in borehole heat exchangers and their thermal resistivity for the design of a so-called lower heat source for a geothermal/ground source heat pump. The offer includes TRT design, execution and interpretation of results.

TRT test with measurement and recording of borehole temperatures at different depths of a borehole heat exchanger with an assumed symmetrical interval. The offer includes the design of the DTRT, execution and interpretation of the results.

Tests of borehole heat exchangers, for very large borehole heat exchanger fields - the tests enable optimisation of the operation of borehole heat exchangers with a very large number of exchangers, defining the variability of borehole heat exchanger parameters from their operation technology. This makes it possible to reduce operating costs. Both tests are based on several thermal response tests. The offer includes the design of the , execution and interpretation of the results.

Borehole temperature profiling to determine the average temperature in the borehole and the temperature distribution along the length/depth.

Determination of theoretical and actual hydraulic characteristics of borehole heat exchangers of different designs.

Determination of the lower heat source concept with borehole heat exchangers (design) on the basis of the thermal properties of the rock or by means of a test borehole, design of the number of borehole heat exchangers needed, their depth, distance between them, design, trajectory of the borehole axes and their arrangement. The parameters depend on the size of the heat/cooling demand and the specific load.

Determination of the potential energy performance of a lower heat source with borehole exchangers based on the design. The design determines the thermal properties of the rock or parameters of the test hole, determines the number of borehole heat exchangers, their depths, distances between them, structures, trajectories of the borehole axes and their placement. The analysis indicates possible heating/cooling loads and the possibilities of their seasonal distribution.

Determination of:

• potential energy performance of the lower heat source with borehole heat exchangers (i.e. heating/cooling capacities and amounts of exchanged heat),
• possible variants for seasonal loading of borehole heat exchangers,
• selection of additional sources in case of heat/cooling shortages for momentary loads or for storing energy in the rock mass (heat/cooling),
• thermal properties of the rock or parameters of the test hole (effective thermal conductivity in the hole and thermal resistance of the hole exchanger on the basis of tests performed or test results provided),
• number of holes, required depth, distance between them, construction, trajectory of hole axes and their arrangement,
• operational parameters of a single hole heat exchanger or of a whole field of holes.
