This paper presents preliminary simulation results from a Modelica – based dynamic model of a solar-powered ground source heat pump (GSHP) system. The model is calibrated and tested using the data collected from a test rig in the laboratory. The preliminary data collected from the test rig includes temperatures for water and air loops, solar heat radiation flux, solar panel output power, and power consumption of the GSHP. This preliminary study is focusing on the comparisons between Modelica model outputs and experimental data, which includes the power consumption of the GSHP unit, unit cooling capacity, and unit coefficient of performance (COP).
