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.
