Ground source heat pump, Heat exchanger, Experiment, Numerical simulation


Horizontal ground heat exchanger in ground source heat pump systems is susceptible to ground surface variations thus affecting its thermal performance. However, this configuration is desirable due to low installation costs as it mainly involved burying pipes in shallow trenches. In this study, the numerical simulation of thermal performance for slinky horizontal ground heat exchanger (GHE) loops in several operation modes is conducted in order to estimate the performance. This study also deals with experimental investigation of slinky type GHE buried in 1.5 m depth of the ground.
