This also applies for thermodynamic and thermo-hydraulic systems i.e. also for the air conditioning system (HVAC) of an automotive vehicle. In order to optimize the efficiency of HVAC-systems and to obtain a better understanding of the complex transient system behaviour of automotive refrigeration cycles a Modelica library named ACLib was developed in a joint research project by DaimlerChrysler AG, Airbus Deutschland GmbH and TUHH. It was based on the thermo-hydraulic models of the free ThermoFluid library[2] and was applied to automotive refrigeration cycles running on the refrigerants R134a and carbon dioxide in an early development stage, when only limited experimental data was available [1, 5]. ## Site Description Modelon is revolutionizing the engineering design industry by offering technologies and services that enable customers to leverage system simulation.
