Presented in this paper is the work undertaken to understand the ability to model an automotive cabin in the 1D Modelica environment including how energy efficient glazing can be modelled to determine improvements in heating or cooling efficiency at extreme ambient temperatures which will have an effect on fuel economy or electric propulsion range in an electric vehicle (EV).
The whole vehicle model and its sub-systems including the cabin and HVAC models are built using the Dymola (DYnamic MOdelling LAboratory) multi-domain physical systems engineering tool, the modelling approach to each subsystem will be discussed in this paper. The air conditioning system model has been created using 1d thermo-fluid physical models. The cabin has been modelled as a multi-zone 1d thermo-fluid model with layering effects.
