Abstract
Geothermal heat pump systems are considered to be environmentally-friendly solutions for residential use. The popularity of these systems is expected to rise but the information on their hydrodynamic and thermal impact is scarce. This paper focuses on how the hydraulic conductivity influences the impact on the reservoir caused by a single well-doublet in a shallow geothermal reservoir. The system is able to produce a maximum of 9.44E-04 m3/s groundwater when installed on a sandy area. Six different strata were defined; the top layer does not take part in water transportation in the original case, but it does have similar features to the lower layers. Scenarios were created to show how the hydraulic effect and the thermal impact change as a function of the hydraulic conductivity of the different layers, while the production was constant. The minimum and maximum values were defined based on the Hungarian conditions.
