Reference data set for injection and extraction cycle of a borehole thermal energy storage field: A numerical and experimental study

Borehole thermal energy storage systems are utilized across the globe to capture solar or residual thermal energy and store the heat seasonally. Although many borehole thermal energy storage facilities exist and operate, there are few facilities that are equipped to provide data and be used for research purposes. This paper provides an extensive experimental dataset of the operation of a borehole thermal energy storage field. The operating …
