Geothermal Heat Pump Systems

2023
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 ...

Geothermal Heat Pumps

Journal of Energy Engineering, 2007
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

Utilization of geothermal waters for heating by heat pumps

Heat Recovery Systems and CHP, 1989
Abstract 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.
