A Case Study of Thermal Evolution in the Vicinity of Geothermal Probes Following a Distributed TRT Method

To meet the stated climate change targets and to ensure capability of meeting current future energy demands, there is an urgent need develop renewable sources, such as geothermal systems. If systems are be cost-efficient enjoy public confidence, it essential that they designed installed in accordance with prevailing site-specific conditions. A thorough understanding thermal behaviour surrounding ground is, therefore, critical. In this work, we investigated temperature its evolution vicinity a shallow helix-shaped borehole heat exchanger (BHE). measure close actual system, additional U-tube probe was at edge same borehole. load then applied BHE, detected nearby U-tube. The measurements were made GEOSniff monitoring device. understand these localised context Valencia test site, ERT also performed. device permits very high depth resolution, which allows properties derived precisely, thus, enabling identification different textural domains.
