摘要：In the paper the simulations of the low enthalpy energy source for brine-to-water heat pump using EED software had been presented. Authors indicated the influence of the ground parameters’ assumptions on the low enthalpy heat pump’s energy source simulation’s results. Based on the real borehole geological profile and data available in literature, the ground thermal conductivity coefficients have been calculated making different assumptions concerning the ground thermal properties. The calculated ground thermal conductivity coefficients along with the calculated source sizes, heat pump parameters and the heated building thermal performance served as the input data for the simulation software. The outcomes of the analyses include the temperatures of brine entering the heat pump as well as the brine initial temperature. Outcomes served for the low enthalpy energy source performance evaluation.
