A CAE SIMULATION MODEL FOR VEHICLE AIR CONDITIONING SYSTEM

In this paper a mathematical model is presented to simulate vehicle A/C system under transient operating conditions. The model consists of several sub-models such as evaporator, condenser, compressor, orifice, air handling system, and connecting hoses. The pressure loss and heat capacity of the evaporator and condenser are investigated in this simulation. Exit air temperature and flow rate from registers are the output of this model which can be used as the input for the passenger compartment simulation. Users can take advantage of this CAE tool to optimize the A/C system design and to minimize the development process with time-saving and cost-effective perspectives.
