Modelling and Experimental Characterization of Solar-Assisted Ground Source Heat Pump Systems with and without Thermal Energy Storage for Cold Climates
… of low energy technologies for building heating and cooling. Among the efficient energy technologies and systems developed to enhance efficiency and reduce building carbon footprint, the use of ground source heat pumps (GSHPs) is gaining traction as a cost-competitive, reliable, and …

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 …

Investigation of a heat pump reversible in an organic Rankine cycle and its application in the building sector
This thesis studies the concept of reversible heat pump / organic Rankine cycle (HP/ORC) and its application in the building sector. Chapter one describes this HP/ORC system and its possible applications. A tool based on operating maps is developed to determine the feasibility of such a system …

Thermal sustainability of low-temperature geothermal energy systems: System interactions and environmental impacts.
In storing heat during summer for use in winter, the ground provides a better source/sink of heat than the outside air in regards to heat pump efficiency, being cooler than the outside air in the summer and warmer in the winter. Due to their good efficiency, the use of geothermal energy is often …
