We present an original tool for analyzing the dynamics of a wide range of thermal energy systems using Modelica, developed by the Central Research Institute of Electric Power Industry in Japan. This tool was originally developed to analyze thermal power generation systems and has been validated against several sets of operational data so far. This paper reports the extension of the tool to the calculation of the thermophysical properties of not only water/steam and air/gas but also various refrigerants implemented by the ExternalMedia library. This addition expands the range of energy systems that can be analyzed with the tool. To validate the simulation data, a comparison between experimental and simulation data targeting a CO2 heatpump loop facility was drawn.
