    • Thermal response of helix ground heat exchangers 

      Fossa, Marco; Stutz, Benoit; Priarone, Antonella; Coperey, Antoine (International Ground Source Heat Pump Association, 2017)
      This paper is devoted to the thermal analysis of shallow ground heat exchangers with pipes arranged in a helix configuration. The pipes where the carrier fluid is circulated typically embrace a cylindrical volume that is ...

    • Three dimensional numerical simulation of double-U pile heat exchangers 

      Wang, Zhonghao; Hu, Pingfang; Xing, Lu; Zhu, Na; Lei, Fei (International Ground Source Heat Pump Association, 2017)
      The Ground Source Heat Pump system with pile heat exchangers has been used in engineering in recent years. In this paper, a three-dimensional numerical model of double-U pile heat exchangers is established which was verified ...

    • Transient thermal resistance of borehole heat exchangers for hourly simulations of geothermal heat pumps systems 

      Priarone, Antonella; Fossa, Marco (International Ground Source Heat Pump Association, 2017)
      The correct design of borehole fields requires the correct evaluation of the transient ground thermal response in time, but also the accurate estimation of the borehole (BHE) thermal resistance, expecially the grout ...

    • Updated assessment of the technical potential of geothermal heat pump applications in the United States 

      Liu, Xiaobing; Hughes, Patrick; Spitler, Jeffrey; Anderson, Arlene (International Ground Source Heat Pump Association, 2017)
      This paper presents an updated assessment of the technical potential of applying geothermal heat pump (GHP) systems in businesses and homes of the United States. The assessed technical potential includes energy savings, ...

    • Vertical GSHP systems in Sweden 1978-2015 - A survey based on the Swedish Well Database 

      Juhlin, Kristina; Gehlin, Signhild (International Ground Source Heat Pump Association, 2017)
      The Geological Survey of Sweden (SGU) is the Swedish government agency responsible for groundwater, geological and mineral management in Sweden. SGU provides open access geological data on rock, soil and groundwater ...
