Long-term Effects of Ground Source Heat Pumps on Underground TemperatureX. Zheng
Wayne State University, Detroit, MI, USA
This study set up a numerical model in COMSOL Multiphysics® and simulated the underground temperature over 100 years. The long-term underground temperature around an energy pile was investigated without considering groundwater movement. Parameters and boundary conditions were examined before the simulation. The temperature changes at different depths and distances were presented. Temperature decreases were found in half-compensation and no-compensation conditions, and the decrease processes were found happened mainly within the first decade.
