An investigation into the performance of a very shallow borehole thermal energy store for a solar-assisted ground source heat pump
Ground-source heat pumps (GSHP) have been used in building applications to meet heating needs at lower energy costs. Likewise, solar thermal systems have been integrated into conventional GSHP to reduce the size of the ground heat exchanger and provide seasonal heat storage. So far, this technology …
