Abstract

This paper explores the measurements of subsoil parameters in geothermal heat pump systems located in historical centers. A closed loop geothermal system serves the heating and cooling requirements of a wing of the Grand Duke historic Palace in the old town district of Pisa. The subsoil temperatures are measured at different depths and positions around the closed loop probes to investigate the thermal diffusion in the subsoil. Water flows, electrical power, flow and return temperatures and other plant data are analyzed to study the geothermal plant energy behavior during the operation.
