This study presents a novel performance evaluation algorithm for horizontal GCHPs (ground coupled heat pump systems) that considers rainfall infiltration. The influence of rainfall infiltration on the thermal characteristics of shallow trenches is examined using infiltration analyses, and then a...

This study presents experimental and numerical research results in determining an effective borehole thermal resistance of a spiral coil energy pile. A precast high-strength concrete (PHC) energy pile with a spiral coil GHE was installed and thermal response test was carried out to evaluate the...

This paper presents a numerical and experimental study on the evaluation of borehole thermal resistance with TRT (thermal response test) and TPT (thermal performance test) results observed in closed-loop vertical type boreholes with U and W type GHEs (ground heat exchangers). Field TRTs were...
