The ground loop system plays a critical role in the performance of a geothermal irrigation preheating system. The length and depth of the pipes, as well as the type of fluid used, can impact the system’s efficiency. A longer pipe length and deeper burial can increase the system’s heat transfer capacity, but may also increase installation costs. The fluid’s thermal properties, such as its specific heat capacity and viscosity, also affect the system’s performance. Proper design and installation of the ground loop system are essential to ensure optimal system operation.
