This investigation examines the performance of a U-shaped vertical ground-coupled heat exchanger (VGCHE) under a range of soil conditions. A three-dimensional model of a U-shaped tube with a diameter of 0.0254 meters and a depth of 17 meters was developed to replicate the heat transfer process. The CFD model is solved with the assistance of the Finite Volume Method (FVM), which employs a range of different intake water flow rates. The temperature of the soil is predicted by a model of convective heat transfer between the surface of the soil and the air surrounding it to change in tandem with the surface temperature of the soil. An experiment was carried out at the National Institute of Technology Jamshedpur in India to offer evidence for the dynamic thermal behavior of the VGCHE under a range of soil surface conditions. During hot summer days the performance of VGCHE is efficient under wet sheltered condition when soil act as a heat sink and during cold winter days dry sunlight condition is most suitable for VGCHE when the soil act as a heat source. It is often utilized in residential, commercial, and industrial buildings for the production of hot water in addition to the heating and cooling of the interior.
