GNRG's Geoaccumulatori

GNRG's Geoaccumulatori are underground heat sinks consisting of a special geometry (patent application, 102,015,000,082,522 of 11/12/2015) and were developed by HTE (www.hte-engineering.com) In cooperation with Albo Consulting Holding in the last three years of research through the creation of numerical models of thermal diffusion.


A differenza dei sistemi tradizionali in cui lo scambio termico col terreno avviene esclusivamente attraverso l’interfaccia in plastica della sonda, la cui bassa conducibilità termica impone un’ampia superficie di scambio (per questo si richiedono sonde lunghe più di 150 m), i geoaccumulatori sfruttano:

• a double exchange interface: One in plastic with water-water exchange realized through a tube bundle, and one in high conductivity steel which realizes the water-earth exchange;




• a double circuit: The first connected to the heat pump as in traditional geothermal plants and the second connected to an external heat sink which allows the continuous regeneration of the field.
