Noise Reduction Measures in Acoustic-Room Air Conditioning System of A Broadcasting Center

广播中心技术用房除满足空调舒适性要求外,还需满足房间噪声要求,讨论在施工图设计阶段的降噪措施,包括技术房间和空调机房的土建隔声、吸声措施,空调机房的设置,末端空调设备的确定,风管风速的确定,减少气流噪声和环境噪声,房间防串音措施以及消声器的确定。

In addition to air-conditioning comfort,the acoustic rooms of a broadcasting center also need to meet the requirement of noise control.This article discusses the noise reduction measures in the design stage of construction drawings,including sound insulation and sound absorption measures in the acoustic room and air-conditioning equipment room;the setting of the air-conditioning equipment room;the determination of the terminal air-conditioning equipment,and of the duct wind speed;the reduction of airflow noise and environmental noise;anti-crosstalk measures in the rooms and the determination of muffler.
