Ground coupled heat pumps of high technology

Objective

The project GROUNDHIT aims at improving cost-effectiveness, competitiveness and market penetration of ground coupled heat pumps. The project involves 16 partners from 11 countries, three of which are new states and a budget of ¿3.644.134 (22,7% R&D, 59,5% Demo and 14,4% Innovation) requesting EU Funding of ¿1.760.832 (48,32%), focusing on the following:

- Borehole Heat Exchanger (BHE) Research: Optimisation in terms of heat transfer with the earth, standardization and development of a prefabricated prototype, resulting in advanced vertical BHE.

- Ground coupled heat pumps research focusing on the theoretical design and laboratory experimentation: Optimisation of ground source heat pumps (electrical water source heat pumps intended to be used together with a borehole heat exchanger) in terms of COP. We anticipate to increase the energy efficiency of such heat pumps from maximum COP-4,5 to COP>5,5 and the corresponding SPF from 3,9 to over 4,5. Development of electrical ground source heat pumps able to deliver 80°C hot water (existing units cannot deliver more than 65°C). Optimisation of electrical water source heat pumps intended to utilize hot groundwater up to 40°C as a heat source in terms of COP. We anticipate raising the energy efficiency of such heat pumps to COP well over 7, depending on the temperature of the input hot water.

- Prototypes development and demonstration of the above technologies: Ground source heat pump of COP>5,5, coupled with prefabricated borehole heat exchangers in Portugal. Ground source heat pump delivering 80°C hot water, coupled with prefabricated borehole heat exchangers in Austria. 40°C water source heat pump of COP>7, coupled with a hot water geothermal well in Greece. Demonstration of ground source heat pump of COP>5,5 with the aid of the Mobile Geothermal Demo Kit.
