METHODOLOGICAL INFORMATION
--------------------------
The investigated system at the dairy (see '01_Figure_1_schematic_flow_chart_sensor_positions_overall_system.png') consisting of a chiller, an integrated HTHP, thermal storage and a Cleaning-In-Place (CIP)-System was modeled using the modelica-based TIL-Suite in Dymola (see publication above for detailed information).
This dataset includes the simulation results from a model-based analysis of the system in a dairy, as well as experimental data.
