对风机盘管噪声测试与控制方法的讨论

Experimental Investigation on Noise Level in Terminal Air Conditioning Unit

讨论了空调工程中常用的末端装置-风机盘管机组噪声测试方法和控制措施。依据相关标准规定,对A声压级测试方法进行了讨论。对于大多数末端设备,各种噪声源和路径会带来室内噪声问题。噪声源的控制需要与产品内部结构的设计相符,噪声传播路径的控制着重于使房间或建筑内末端设备安装工艺更合理。

Noise level is an important parameter in air conditioning terminal unit. In order to get a quiet and comfortable room condition, some sound pressure level tests and controlling methods are discussed for fan-coil units which are the typical terminal unit in air condition engineering. The A-weighted sound pressure level is measured with test standard for national code. For most terminal units multifarious sound sources and transmission paths can cause noise problems in rooms. For sound source control, it is necessary to getting a reasonable match of the product＇s internal structure design. For sound transmission path control, getting a well combination for the unit installation in a room or a building is also important.
