This webinar presents the research, development and assessment of various typologies of heat pumps and ground source heat exchangers (GHEX) studied in the EU-funded project GEOFIT which focuses on geothermal retrofitting across a range of building typologies (residential, tertiary, educational).
Regarding GHEX, different typologies have been studied such as vertical and horizontal boreholes, slinky HEX, and earth baskets. Test campaigns were performed both in the lab and at the pilots and optimal geometries were studied aiding to the development of an engineering tool for optimal sizing of the GHEX presented.
Regarding heat pumps, different typologies of electrical and heat-driven Heat Pumps (HP) have been optimised and implemented to include high temperature HPs with low GWP refrigerants, off-the-shelves HPs integrated in residential retrofitting projects, and hybrid HPs using gas and heat to supply heating and cooling. Results from analysis, prototyping and fielding are presented.
