The objective of this project is the development of an air conditioning system based on geothermal heat exchangers that overcome space limitations.
To do this, we have made use of geothermal wells whose depths far exceed the 100m typically used today. With boreholes of 500m or more it is possible to significantly reduce the total number of geothermal wells required in a building, which translates into a much lower free surface area requirement for drilling than is currently the case. In addition, the use of deep drilling increases the energy efficiency of the air conditioning system, in particular the COP ("Coefficient of Performance") of the geothermal heat pump, because at such depths the ground temperature is significantly higher than at 100m.
In addition, within the framework of this project we have developed a new high-performance geothermal filler with improved thermal, mechanical and hydraulic properties.
