Results of numerical simulations more and more provide a basis for design decisions in an automotive context. When simulating complex systems; one of two approaches can be chosen: The modeling in one multidomain language like Modelica or the utilization of different specialized simulation programs.

This paper demonstrates the simulation of the Heating Ventilation and Air-Conditioning system (HVAC) of a car. The different components are modeled individually and validated with measurement data in separate test benches. A co-simulation using one Dymola instance per component model is then created to represent the whole refrigeration cycle taking into account the inter-component dependencies.

To evaluate the effects introduced by the tool coupling; the results are compared to those of a single Modelica model composed of all component models.
