Geothermal heat pumps use the earth as a source of and sink for thermal energy used and given off by structures to be space conditioned. Closed and open loops of polyethylene pipe are placed into the ground or into surface waters to effect heat exchange with the earth. The space conditioning...

The main objective of the present study is twofold: (i) to analyze thermal loads of the geothermally and passively heated solar greenhouses; and (ii) to investigate wind energy utilization in greenhouse heating which is modeled as a hybrid solar assisted geothermal heat pump and a small wind...

Vertical BHE (borehole heat exchangers) are a common solution for GCHP applications (ground coupled heat pump). Correct BHE design and sizing are mandatory to either assure long term GCHP performance or reduce the payback period. Most models for performing the time varying analysis of complex...
