Energy-saving potential of ground source multiple chillers in simple and hybrid configurations for Mediterranean climates

Coupling a road solar thermal collector and borehole thermal energy storage for building heating: First experimental and numerical results

“…Hourly-based dynamic simulations of the operation of the plant in its first 5 years of life allowed both the sizing of the BTES in terms of the total number and distance of BHEs, and the definition of the annual energy that can be recovered in the winter period to be delivered to the evaporators of a heat pump. A comparison with a conventional Geothermal Heat Pump (GHP) [34] shows that the proposed RTC-BTES system makes it possible to reduce the overall length of the exchangers by about three times.…”

“…"Type 557" has been modified to allow for a variable overall borehole thermal resistance via the following expression [34]:…”

“…To evaluate the advantage, in terms of overall BHE reduction, of the RTC-BTES system over an equivalent conventional GHP system [34] the following procedure was followed:…”
