摘要：The paper presents the ground temperature analysis, heat flows
and energy transferred from the soil massif by the vertical ground heat
exchangers (VGHE). Three cases – with one, two and three vertical heat
exchangers were compared. Their influences on the soil massif temperature
in the heat exchangers area were shown. The mass flow and the temperature
at the inlet and outlet side of the heat pump were measured in each circuit.
Additional, the electricity consumption by the heat pump and energy supply
to buffer vessel were measured. Finally, the Coefficient of Performance
(COP) as a function of length of VGHE is shown for selected interval time.
