      Spitler, Jeffrey D.; Acuna, Jose; Bernier, Michel; Cimmino, Massimo; Fang, Zhaohong; Gehlin, Signhild; Javed, Saqib; Liu, Xiaobing; Rees, Simon; Stumpf, Andrew; IGSHPA Research Track (2022) (International Ground Source Heat Pump Association, 2022)
    • Ground heat exchanger design tool with rowwise placement of boreholes 

      Spitler, Jeffrey D.; West, Timothy; Liu, Xiaobing (International Ground Source Heat Pump Association, 2022)
      Simulation-based design tools have been used since the late 1980s for designing ground heat exchangers (GHE) used with ground source heat pump (GSHP) systems. The ground heat exchanger simulations used in these tools rely ...
    • Long-term GSHP system performance measurement in the USA and Europe 

      Spitler, Jeffrey D.; Gehlin, Signhild E. A. (International Ground Source Heat Pump Association, 2022)
      This paper presents an overview of the International Energy Agency (IEA) technology collaboration program Heat Pumping Technologies (HPT) Annex 52, "Long term performance measurement of ground source heat pump (GSHP) systems ...
    • Model for ground temperature estimations and its impact on horizontal ground heat exchanger design 

      Xing, Lu; Spitler, Jeffrey D.; Li, Liheng; Hu, Pingfang (International Ground Source Heat Pump Association, 2017)
      The ground-source heat pump systems are highly efficient and energy saving. Its main disadvantage is a significantly higher installation cost compared to conventional systems. The length of the ground heat exchanger (GHX) ...
    • Open library of g-functions for 34,321 configurations 

      Spitler, Jeffrey D.; West, Timothy; Liu, Xiaobing; Borshon, Ishraque (International Ground Source Heat Pump Association, 2022)
      Thermal response functions, known as g-functions, are commonly used in ground heat exchanger design tools and whole building energy simulation programs to simulate the ground heat exchanger performance. Calculation of ...
