Thermal short circuit on groundwater heat pump

Thermal breakthrough is common in groundwater heat exchange systems, particularly in historical town districts where the distance between wells is necessarily close due to buildings proximity and the possibility of other group plant in the neighbourhood. Most probably due to modelling difficulties, it is unusual to take into account this type of thermal contamination during an ordinary analysis of the interaction between and consequences of groundwater heat pump and aquifer systems. An approach using complex open loop modelling allows the analysis of a case of thermal feedback in order to obtain the best planning and use of the geoexchange plant.
