Monitoring of a vertical borehole ground-coupled heat pump system: A case study from a marly-limestone heat reservoir (Urbino, Central Italy)

摘要

This paper presents a case study of a vertical borehole ground-coupled heat pump (GCHP) system operating in Urbino (Central Italy), and includes an assessment of its seasonal performance and impact on the sedimentary heat reservoir from October 2010 to October 2014. The GCHP is installed in a commercial building and monitored by means of temperature and thermal energy data loggers. The temperature of the ground heat reservoir at various depths is also monitored down to a depth of 100m, by means of temperature profiles measured along a borehole heat exchanger and in a monitoring well drilled ad hoc at a distance of 2.2 m.
