Heat Transfer Modeling of the Ground Heat Exchangers for the Ground-Coupled Heat Pump Systems
Ground-coupled heat pump (GCHP) systems have been gaining increasing popularity for space air conditioning in buildings due to their reduced energy and maintenance costs. The efficiency of GCHP systems is inherently higher than that of the traditional options because it utilizes the ground which maintains a relatively stable temperature all the year round as a heat source/sink. Compared with tr...
متن کاملNumerical Modeling of Slinky-coil Horizontal Ground Heat Exchangers Considering Snow Coverage Effects
The number of Slinky-coil horizontal ground heat exchangers (HGHEs) has been increasing in geothermal heat pump (GHP) systems due to the low initial cost. The performance of the Slinky-coils, however, has not been successfully predicted with good accuracy since the complicated shape of the Slinky-coils is not easy to model either analytically or numerically. To enable this, Fujii et al. (2012) ...

متن کاملImprovement in Modeling of Heat Transfer in Vertical Ground Heat Exchangers
The heat transfer model of vertical ground heat exchangers for ground-source heat pump systems is discussed. An explicit solution of a finite line-source model has been derived to better describe temperature response of boreholes for long time steps, which can be easily incorporated into computer programs for thermal analysis of ground heat exchangers. A quasi-three-dimensional model is also pr...
