地铁通风空调系统消声降噪分析与设备应用

Application and Analysis of Subway Noise Elimination Equipment of Ventilation and Air-conditioning system

研究目的:地铁以它快捷、方便、舒适的特点为人们的出行提供了便利条件,但地铁列车以及相关机电设备的运行所产生的噪声给人们的生活造成了极大影响,因此需要对地铁的消声降噪进行研究。研究方法:针对地铁通风空调系统的构成及设备组成,结合现场实测资料,分析地铁主要噪声源和降噪消声设备的选择。研究结果:地铁通风空调设备是地铁噪声的主要噪声源之一。消声降噪设备应满足声学、空气动力学、加工等方面要求。研究结论:地铁通风空调系统要采取科学合理的降噪消声措施。阻性片式消声器可以对噪声进行有效的控制和消除。

Research purposes： Subway has provided convenient communication conditions for people with its rapid, convenience, comfort. But the noise of subway train and series of electromechanical device has been brought about extremely affection on people＇s life. Therefore it is need to study on the noise elimination of subway system. Research methods： Aiming at compose of subway ventilation and air - conditioning system and device, it analyses the main subway noise source and denoise noise elimination equipment choice in site measurement data. Research results： Subway ventilation and air- conditioner is one of main noise source. Noise elimination denoise equipment responds to the request satisfying acoustics , aerodynamics , processing aspect Research conclusions： The ventilation and air - conditioning system asks a subway to adopt rational denoise of science noise elimination measure. Dyadic impedance movie deadener can carry out effective controlling on noise and eliminates.
