Abstract: Maintaining air quality is essential to the functions of our everyday.HVAC systems used in industrial and residential spaces and composed of ducts, dampers, silencers and others elements are necessary to keep high-quality and clean air indoor spaces.In this work, we studied the acoustic parameters of the blade's damper, which are an integral element of VAV and CAV systems in ventilation.The dampers under study varied fixing systems into duct.The two common fixes of blade damper -circular and square rods and three, non-disturb flow, specially constructed fixes for blade dampers were tested.The finite element method for simulations of the flow and acoustic parameters of the study objects was used.The simulation results were compared for blade's damper with different fixing into the duct.
