Апстракт:
Geothermal Heat Pumps (GHP) belong to a class of modern sustainable technologies that use energy (heat) available underground in heating or cooling housholds and residential buildings, as well as commercial and industrial spaces. They are widely deployed accross Europe and enable savings in primary energy sources, simultaneously cutting down the costs of heating/cooling. In this paper, we discuss the advantages of GHPs, especially the pumps of the type earth-water, and give a comparative analysis of different types of those pumps currently available on the market according to their coefficient of performance (COP), CO2 emission footprint, power, and price. Based on the collected data from 309 different GHP models coming from 39 different manufacturers, we derive expressions for characterizing GHPs of the type earth-water, which can be useful in performing initial feasibility studies and system designs.
