在暖通空调行业里,大部分声音或噪音生成是通过管道转动设备、空气、液体。这个运动产生振动、声音。从技术上讲,声音是穿过物质的机械能。噪音是不受欢迎的噪是音没有价值是不受欢迎的。在这个讨论中,我们也将使用声音和噪音。
在空调行业,振动在其最简单的形式可以被视为一种振荡或重复的运动对象，声音不是生成没有某种形式的振动设备。虽然声音存在振动,但振动对于人耳来讲很小。
因此,最好的方法来减少噪音是限制产生噪音的振动机械设备。比如旋转的轴和齿轮的热过程,如燃烧,或流体动力学方法如气流通过管道或风扇与空气的相互作用。
Vibration, sound, and noise can be mitigated by designing HVAC systems properly, which may include isolation pads, flexible pipe connectors, or other means.

Learning objectives
Understand the factors that may cause noise or vibrations in HVAC systems.
Learn various methods to mitigate vibration, sound, or noise problems.
In the HVAC industry, most sound or noise is generated via rotating equipment and air and fluid move-ment through ducts and pipes. This movement creates vibration, sound,
or noise. Technically, sound is a wave of mechanical energy that moves through matter. Noise is undesirable sound or sound without value. In this discussion, we will use sound and noise synonymously. |
