Geothermal heat pumps can be considered a sustainable technology, as they reclaim and recycle thermal energy from the earth. In climates with a near balance in the annual heating and cooling loads, they function essentially as a seasonal energy storage scheme. This paper presents an overview of the technology. The various types of geothermal heat pumps

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

This book presents an overview of geothermal heating systems using ground source heat pumps in different countries. It evaluates the emissions and energy costs generated by the operation of low enthalpy geothermal systems, with heat pumps fed by different energy sources, and assesses, from an international point of view, those policies whose aim is a ...

Utilization of geothermal waters for heating by heat pumps
Heat Recovery Systems and CHP, 1989Abstract This paper treats the solution to the problem of the connection of heat exchanger and heat pumps in geothermal district heating systems. A numerical solution for the theoretical Rankine heat pump cycle is presented to determine the thermodynamic process efficiency as a criterion of quality of energy flow in the process of its transformation.

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 ...
