VAV control system hunting is one of the most severe problems of VAV air conditioning systems. Develops dynamic models to the air conditioned room and controller, exploits a set of computer simulation software. The simulation results show that the stability region of VAV control system is influenced by the control and system parameters. The ultimate parameter model could be used for guidance in engineering practice.
