Title: In-situ measurements of ground thermal properties around borehole heat exchangers in Plovdiv, Bulgaria
Keywords: Thermal response test, Ground thermal properties, Borehole heat exchangers

Abstract: The knowledge of the geodata (subsurface characteristics) is important for the design and construction of the Underground Thermal Energy Storage (UTES). In situ determination of ground thermal conductivity, borehole thermal resistance and undisturbed soil temperature can be done by installing a vertical borehole heat exchanger (BHE) and performing the so-called Thermal Response Test (TRT). The knowledge of the underground characteristics is very important to design an installation using Borehole Thermal Energy Storage (BTES) - it is a big advantage during the project calculations and the construction of the geothermal systems. This paper describes the determination of ground thermal properties by a research group of the Technical University of Sofia, Plovdiv branch. A mobile system for conducting Thermal Response Test has been created recently in Plovdiv, Bulgaria. The first Bulgarian TRT was carried out in January 2009 using a BHE with a depth of 41 m (constructed in November 2008).
