Advanced ground source heat pump systems for heati.. (GROUND-MED)
Advanced ground source heat pump systems for heating and cooling in Mediterranean climate
Start date: Jan 1, 2009,
End date: Dec 31, 2013
GROUND-MED project will demonstrate geothermal heat pump (GSHP) systems for heating and cooling of measured SPF>5,0 in 8 demonstration sites of South Europe. As the SPF is determined not only by the heat pump unit, but by its operating conditions imposed to the heat pump by the ground heat exchanger and the heating/cooling system of the building as well, integrated systems incorporating the following technological solutions will be demonstrated and evaluated: a) new water source heat pumps of improved seasonal efficiency; key technologies include use of the next generation of compressors, heat exchangers and automation; b) borehole heat exchangers and heating/cooling systems operating with minimum temperature difference between them, which also follows the corresponding heating/cooling demand from the building; design aspects, thermal storage and system controls are important; c) minimum power consumption to system components; key parts are the fan-coil and air-handling units. GROUND-MED has a duration of 5 years and a budget of around 7,3 million euros, comprising 25% research and 75% demonstration and other activities. The GROUND-MED consortium comprises 24 organizations mainly from South Europe, including a wide diversity of GSHP actors, such as research and educational institutes, heat pump manufacturers, national and European industrial associations, energy consultants and works contractors.
