Solar and ground source heat-pump system
Applied Energy, 2004Theoretical and experimental studies were performed for a solar-ground source heat-pump (SGSHP) system with a vertical double-spiral coil (VDSC) ground heat-exchanger (GHX). The heating mode of the SGSHP system is alternated between a solar energy-source heat-pump (SSHP) and a ground-source heat-pump (GSHP) using a low-grade energy utilization system ...

Hybrid ground-source heat pump systems
Applied Mechanics and Materials, 2016Operating data in the last two years of a hybrid ground-source heat pump system (HGSHPS) were analyzed, and were contrasted to TRNSYS simulation results. Heat extraction from the borehole heat exchanger (BHE) of ground-source heat pump system (GSHPS) was too much larger than the heat injection, but heat extraction from the borehole thermal energy ...

Alternative refrigerants for the heat pump of a ground source heat pump system
Applied Thermal Engineering, 2016Abstract It is attempted to define more environment friendly working fluids for the heat pump of ground source heat pump systems (GSHPSs). The examined case is an office building with total cooled area 1000 m2, which is connected with such a system. The energy demands are computed by TRNSYS 16.1 and the ground loop is modeled by GLD2009.

Ground-source heat pumps systems and applications
Renewable and Sustainable Energy Reviews, 2008Ground-source or geothermal heat pumps are a highly efficient, renewable energy technology for space heating and cooling. This technology relies on the fact that, at depth, the Earth has a relatively constant temperature, warmer than the air in winter and cooler than the air in summer. A geothermal heat pump can transfer heat stored in the Earth into a
