2. General description
2.1. Type description
The range of ecoGEO heat pumps is available in two structures, ecoGEO B and ecoGEO C. The ecoGEO C series includes a DHW
storage tank that is integrated in the structure, while the ecoGEO B series is designed for installation with various external DHW
storage tanks. Heat pumps with a variety of options can be installed in each of these structures; indicated in the name type.

2.2. Operating principles
Geothermal heat pumps are comprised by three main circuits: brine circuit, cooling circuit and output circuit. These circuits
transport the thermal energy between the terrain and the various points of consumption (DHW, heating, etc.). The transfer of
energy from one circuit to another takes place through heat exchangers, where the higher temperature fluid transfers heat to the
fluid at a lower temperature without mixing. The temperature of the brine circuit is lower than required for production. Therefore,
to transfer the energy between both circuits, the refrigerant undergoes a thermodynamic cycle during which it evaporates at low
pressure and temperature and condenses at high pressure and temperature, repeatedly. To carry out this process, the compressor
consumes a small amount of electric energy compared to the thermal energy that it supplies.
