This study takes the air conditioning system of the cruise cabin area as the research object, constructs a Simulink simulation model, compares the experimental measurement data with the simulation results for system verification, and focuses on analyzing the air volume distribution and duct resistance characteristics under different fan frequencies. The results show that the duct resistance has a significant effect on the air volume distribution. By adjusting the air valve opening, the air volume distribution can be ensured to be reasonable, and the air volume of the terminal device increases with the increase of frequency. The error between the simulation data and the measured data is controlled within ±10%, indicating that the Simulink simulation model can accurately reflect the air volume distribution and resistance characteristics of the VAV system, verifying its applicability in related research. This simulation model can provide a theoretical basis for the design and optimization of cruise air conditioning systems.
