One laboratory belonging to Energy Engineering Faculty is heated with a ground-coupled heat pump (GCHP) system having two types of ground heat exchangers: a vertical one and a horizontal one. This paper presents, at first, several coefficients of performance that can be defined for heat pumps together with their usability. Then, an energy efficiency model is set specially for CGHP systems. In this paper the simulation of energy performances is done only for the vertical heat exchanger (borehole heat exchanger) having two configurations: single-U and double-U. All simulation results range between normal values and can be considered realistic.
