Abstract

Acoustic noise of air conditioner is one of the main vehicle interior noises. In this paper, the value of the acoustic noise obtained under specific rotational velocities that tested in the experiment has been analyzed and the distribution of the noise with the analysis of the sound field in the HVAC System (heating ventilation and air-conditioning) also has been achieved. A spectrum analysis of outlet noise was used for comparison of variable noise source characteristics. As soon as the HVAC System modeling and simulation completed in the CDF software, it had laid emphasis to analyze the influence of the inner structures of HVAC System on the acoustic noise and two comparisons were made, one between the simulation and the experiment, the other one between the integrated HVAC system and the simplified in the simulation. Good agreement was achieved between simulation and experiment results.
