A near-surface geothermal plant uses the thermal energy stored below the earths surface. Using a two-well system, for example, thermal energy is extracted from the near-surface groundwater for heating purposes. The scope of geothermal energy is the study and use of the heat and the temperature distribution in the ground. It demonstrates the operation of such a two-well system.
Learning objectives/experiments:
Hydraulic properties of the ground
Determination of the usable heat capacity
Fundamentals of geothermal use
Fundamentals and energy balance of a simulated heat pump
Operating behaviour of a two-well system.
