The aim of this paper is a theoretical analysis of the operation of an air-to-water heat pump located in the Labo-ratory for Thermal Science at the Faculty of Mechanical Engineering in Belgrade. This results provide the basis for further experimental analyzes of this installation.The paper gives a comparative overview of the performance of a scroll and reciprocating compressor when pro-pane (R290) is used as a refrigerant. Also, the analysis of the influence of internal subcooling on the thermodynamic cycle is presented. Finally, according to the developed model of the heat pump performances investigation, the change in the average values of Coefficient of Performance (COP) during the average heating season, forthe period 2014 –2018, is shown.
