Technical optimization of the energy supply in geothermal heat pumps
Geothermics, 2019Abstract Very low enthalpy geothermal systems have been traditionally associated to the use of electricity as primary energy heat pumps supply. Gas engine heat pumps (GEHP) have been recently introduced in the current market. In this research, the electric heat pumps (EHP) as well as the GEHPs (considering natural gas and biogas as combustibles) have

Geothermal heating systems using heat pumps
Geothermics, 1985Abstract The geothermal heating system at Creil is one of the first geothermal projects in France, only preceded by the geothermal schemes of Melun-l'Almont (1970) and Villeneuve-la-Garenne (1976). Its design is quite different from that of other geothermal facilities.

Greenhouse Heating with Geothermal Heat Pump Systems
2006 Portland, Oregon, July 9-12, 2006, 2006Geothermal heat pump (GHP) systems are known for their higher energy efficiency, lower maintenance, and lower environmental impact compared to conventional heating systems, but their disadvantage is higher capital cost. The objective of this study is to examine the feasibility of greenhouse heating with GHP systems.

Geothermal heat pumps and acoustics for people who do not know much about geothermal heat pumps.
The Journal of the Acoustical Society of America, 2008Geothermal heat pumps operate more efficiently than traditional heat pumps and air conditioners–much more efficiently–and have no noisy outdoor equipment. Yet, after inquiries to mechanical system manufacturers and to the Technical Committee on Architectural Acoustics Green Building Acoustics Subcommittee listserv, I have not found instances where ...

Sustainable sub-geothermal heat pump heating in Serbia
Renewable and Sustainable Energy Reviews, 2011Abstract Considering the necessity of improvement of Serbian energy production structure through higher participation of clean and renewable energy sources, the possibility of utilization of low enthalpy geothermal waters have been investigated. Energy potential of ground waters of modest temperature levels is usully neglected since it can not be ...

Modelling of Condenser Circuit of the Geothermal Heat Pump
2021An approach to the study of heat exchange processes of the heat pump condenser circuit has been proposed. A mathematical model of the heat exchange process of the heat pump condenser circuit and the consumption line circuit has been constructed. The mathematical model is based on the equations of material and energy balances of the working fluid of the

Heat loss by the Earth, geothermal energy and geothermal Heat pumps
2015Geothermal energy is often labeled as renewable and sustainable. It is listed together with solar, wind and biomass as alternative energy options in governmental R& D programs. The temperature in the Earth’s interior increases with depth. This fact is responsible for the heat flow, from the interior to the surface.
