[EN] GeoCool plant was the result of a EU project whose main purpose was to adapt ground coupled heat pump
technology to coolingdominatedareas. The executionofthis experimentalplant was completedatthe end
of year 2004, starting on February 2005 the regular operation of the air conditioning system. Since then,
GeoCool facility has been monitored by a network of sensors characterizing its most relevant parameters.
Several aspects of the performance and behaviour of the system during its first operational year were
presented on a previous paper. This paper presents the energy performance measurements of GeoCool
ground coupled heat pump system acquired during five years of operation as well as the evolution of the
return water temperature from the ground as a representative of the ground temperature. The analysis
of the experimental results shows that the system energy performance is maintained through the years
with no appreciable impact on ground thermal responseThis work has been supported by FP7 project "Advanced ground source heat pump systems for heating and cooling in Mediterranean climate" (GROUND-MED).Montagud Montalvá, CI.; Corberán Salvador, JM.; Montero Reguera, ÁE.; Urchueguía Schölzel, JF.
