Abstract: A comparative analysis of the Coefficient of Performance (COP) and the Energy Efficiency Ratio (EER), based on the technical data of 430 different models of air-to-water heat pumps (AWHPs) as well ground-source heat pumps (GSHPs), at certain conditions of ambient air, ground source and water outlet from the heat pump (HP) temperatures, is performed. The results, presented in graphical and tabular form, give the COP and EER values against the HPs nominal capacity and the correlation between COP and EER with the temperature rise ΔΤ along the HP...
