There is ahugepotential that the en ergy consumption of the central air- condition can be saved, and the energy smi ulinkmodels are thebasis of the en ergy- saving research. A ccording to the energy mathematicalmodels and the coupling ofdifferent types of equipment in theVAV system, the smi ulink tool box ofM atlab is used to build the smi ulinkmodels that reflect the relationship between the different variables and the energy consumption of the system when theVAV system is running. The result of the energy consumption smi ulation is analyzed and validated in this paper. A t last, themodelbuilt can be used to research the optmi ization ofVAV system s parameter in the purpose of energy saving, and it has mi portantmeanings to the control of the system.
