A novel geothermal heat pump makes cost-effective, energy-efficient heating and cooling of buildings a reality. How? By harnessing heat sources from the air or ground.

An international team of researchers has joined forces to meet Europe's rising need for affordable and efficient geothermal solutions. Their work, which has received EU support through the GEOTeCH project, focuses on providing cost-efficient renewable heating and cooling for houses and small buildings.

GEOTeCH - Team - Market - Reason - International

The GEOTeCH team has targeted this market for a good reason. According to the International Energy Agency, buildings are responsible for 30 % of global energy consumption and a substantial percentage of CO2 emissions. Heating, ventilation and air conditioning systems in particular make up about half of the energy used in buildings. And the sector is expanding, which makes reduced energy consumption and the use of renewable sources even more important.

Project partners have used advances made in geothermal heat pump technology to develop a novel dual-source heat pump (DSHP) unit for heating, cooling and domestic hot water production. An article published in the International Journal of Low-Carbon Technologies provides information on the system's characteristics and performance.

DSHP - Advantage - Air - Ground - Heat

The innovative DSHP takes advantage of either air or ground heat sources, depending on operating and climatic conditions. It's able to select the most favourable heat source or heat sink (for heating or cooling, respectively) in a way that allows it to operate as an air-to-water or brine-to-water heat pump. Therefore, in winter it can provide hot water for heating buildings, using either the air or the brine from the ground as heat sources. Alternatively, in summer, it uses the air or brine as a heat sink to provide...
