组合式空调机组噪声综合控制应用分析

Application Analysis on Integrated Noise Control of Combined Air Conditioning Unit

厦航总部大楼各层均采用大风量组合式空调机组进行制冷、排风以及新风补充,其固体传声及空气噪声严重影响开放式办公区域。文中基于该空调机组的噪声振动机理,介绍设备基础减振浮筑地台、送风口柱体排列式消声器、回风口弧形流道消声器的设计及应用,以改善低频固体传声及高速气流扰动噪声的降噪效果,为组合式空调机组的降噪减振设计提供参考依据。

All floors of Xiamen Airlines headquarters building adopt large air volume combined air conditioning units for refrigeration,exhaust and fresh air supplement.Its solid sound transmission and air noise seriously affect the open office area.According to noise and vibration mechanism of the air conditioning unit,this paper introduces the vibration damping floating platform of equipment foundation,and the air supply outlet adopts the column arrangement muffler,and the air return outlet adopts the arc channel muffler,so as to improve the noise reduction effect of low-frequency solid sound transmission and high velocity air flow disturbance noise,and provides a reference for the noise reduction design of combined air conditioning unit.
