    • Fractal approach to calculate the thermal conductivity of moist soil 

      Cai, Shanshan; Cui, Tengfei; Zheng, Boren; Hu, Pingfang (International Ground Source Heat Pump Association, 2017)
      The ground heat exchanger (GHE) is a key component in the design of a GSHP system and the effective thermal conductivity is one of the most important parameters that determine the heat transfer underground. In this paper, ...

    • 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) ...

    • 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 ...
