A CAE SIMULATION MODEL FOR THERMAL MODELING OF VEHICLE PASSENGER COMPARTMENT

In this paper a CAE model for vehicle climate control system is presented. The mathematical model provides engineers a cost effective analysis tool to design, develop,and optimize the vehicle interior climatic conditions. The present mathematical model predicts the lumped temperature and lumped humidity variations inside the passenger compartment under design and operating conditions. The transient nature of the passenger cabin average temperature, average interior mass temperature and humidity are modeled using three coupled non-linear ordinary differential equations based on mass and energy balance. The validated model is further used to test the effects of variations in certain vehicle structure, air conditioning parameters and composite materials properties in order to investigate the influence on the temperature patterns inside the compartment.The comparison of simulation results with the existing experimental data well proves the validity of work.
