Title: Advanced ground source heat pump systems for heating and cooling in Mediterranean climate
Contract No: TREN/FP7EN/218895/"GROUND-MED"
Starting date: 1 January 2009
Duration: 5 years
Budget: 7.247.686 Euro
EC financing: 4.299.695 Euro
Key words: ground source heat pumps, geothermal heating cooling
The GROUND-MED project demonstrates the next generation of geothermal heat pump (GSHP) systems for heating and cooling in 8 demonstration sites of South Europe. A measured seasonal performance (SPF) higher than 5,0 will be demonstrated. As the SPF is determined not only by the heat pump unit, but by its operating conditions imposed by both the ground heat exchanger and the heating/cooling system of the building, integrated GSHP systems incorporating the following technological solutions will be developed, designed, constructed, installed, monitored and evaluated:
- prototype water source heat pumps of improved seasonal efficiency; key technologies include the next generation of compressors, heat exchangers and automation;
- borehole heat exchangers and heating/cooling systems operating with minimum temperature difference between them, which also follows the heating/cooling demand from the building; design aspects, thermal storage and system controls are important;
- minimum power consumption to auxiliary system components; key parts are the fan-coil and air-handling units.
GROUND-MED with a duration of 5 years and a budget of around 7,25 million euros, comprises 25% research, 60% demonstration and monitoring, 10% dissemination and 5% project management activities. The GROUND-MED consortium consists of 24 European organizations including a wide diversity of GSHP actors, such as research institutes, Technical Universities, heat pump manufacturers, national and European industrial associations, energy consultants, works contractors and an information centre.
