Nibe S2125 - Installation Function

An air/water heat pump installation uses the outdoor air to
heat up a home. The conversion of the outdoor air’s energy
into residential heating occurs in three different circuits.
From the outdoor air, (1) , free heat energy is retrieved and
transported to the heat pump. The heat pump increases the
retrieved heat’s low temperature to a high temperature in
the refrigerant circuit, (2) . The heat is distributed around
the building in the heating medium circuit, (3) .
