This paper presents the current results of the development of a Modelica library for CO2-refrigeration systems basedon the free Modelica library ThermoFluid. The development of the library is carried out in a research project of AirbusDeutschland and the TUHH and is focused on the aim to obtain a library for detailed numerical investigations ofrefrigeration systems with the rediscovered refrigerant carbon dioxide (CO2). A survey of the concept of an integratedon-board cooling system of airliners, the modelling language ModelicaTM and the CO2-library is given and the modellingof CO2-heat exchangers is described. A comparison with steady state results of heat exchangers shows a fair agreement.The presented transient simulation results are compared with experimental data showing also a fair agreement.
