    • 2018 Research Conference Proceedings, International Ground Source Heat Pump Association 

      Spitler, Jeffrey; Acuna, Jose; Bernier, Michel; Fang, Zhaohong; Gehlin, Signhild; Javed, Saqib; Palm, Bjorn; Rees, Simon J.; IGSHPA Research Track (2018) (International Ground Source Heat Pump Association, 2018)

    • Ates system monitoring project, first measurement and performance evaluation: Case study in Sweden 

      Abuasbeh, Mohammad; Acuna, Jose (International Ground Source Heat Pump Association, 2018)
      Performance of Aquifer Thermal Energy Storage (ATES) systems for seasonal thermal storage depends on the temperature of the extracted/injected groundwater, water pumping rates and the hydrogeological conditions of the ...

    • Design of a laboratory borehole storage model 

      Mazzotti, Willem; Jiang, Yifeng; Monzo, Patricia; Lazzarotto, Alberto; Acuna, Jose; Palm, Bjorn (International Ground Source Heat Pump Association, 2018)
      This paper presents the design process of a 4x4 Laboratory Borehole Storage (LABS) model through analytical and numerical analyses. This LABS is intended to generate reference Thermal Response Functions (TRFs) as well as ...

    • Development of a thermal conductivity map of Stockholm 

      Malmberg, Malin; Raymond, Jasmin; Perozzi, Lorenzo; Gloaguen, Erwan; Mellqvist, Claes; Schwarz, Gerhard; Acuna, Jose (International Ground Source Heat Pump Association, 2018)
      New methods have been suggested to spatially extend in situ thermal response test (TRT) assessments based on geostatistical analysis. These methods can be used to determine a stochastic distribution of the subsurface thermal ...

    • High temperature borehole thermal energy storage - A case study 

      Malmberg, Malin; Mazzotti, Willem; Acuna, Jose; Lindstahl, Henrik; Lazzarotto, Alberto (International Ground Source Heat Pump Association, 2018)
      Combining High-Temperature Borehole Thermal Energy Storages (HT-BTES) with existing Combined Heat and Power (CHP) systems running on waste fuels seems to be a promising approach to increase the energy efficiency of district ...

    • Newton-Raphson method applied to the time-superposed ILS for parameter estimation in Thermal Response Tests 

      Mazzotti, Willem; Firmansyah, Husni; Acuna, Jose; Stokuca, Milan; Palm, Bjorn (International Ground Source Heat Pump Association, 2018)
      Thermal Response Testing is now a well-known and widely-used method allowing the determination of the local thermal or geometrical properties of a Borehole Heat Exchanger (BHE), those properties being critical in the design ...

    • Thermal influence of neighbouring GSHP installations: Relevance of heat load temporal resolution 

      Fasci, Maria Letizia; Lazzarotto, Alberto; Acuna, Jose; Claesson, Joachim (International Ground Source Heat Pump Association, 2018)
      In densely populated areas where many ground source heat pump (GSHP) systems are present, it becomes important to consider the thermal influence of neighbouring GSHP installations while designing these systems. This question ...
