The geothermal test bench focuses on earth-contact walls of buildings used as heat exchangers for heating and cooling purposes. The exchanger is made up of three modules that can be deployed in different ways. The installation is equipped with an heat pump, a puffer and the simulated heat load (fan coil).
Testing involves thermal performances of the system as well as the structural, thermal and hygrometric effects on the wall and the surrounding ground thanks to a wide monitoring system.
