    一、新建大型空调机组机房好放置于楼顶或者离无尘室车间20米距离的位置。
    1、 The newly built large air conditioning unit room shall be placed on the roof or 20m away from the dust-free room workshop.
    二、食品厂净化车间小型净化器离心风机选型必须注意噪音问题。
    2、 Attention must be paid to the noise problem in the selection of centrifugal fan for small purifier in the purification workshop of food factory.
    三、食品厂净化车间空气净化工程通风管道必须采用保温效果较好的保温棉,保温棉也可以降低噪音。
    3、 The ventilation duct of the air purification project in the purification workshop of the food factory must adopt the thermal insulation cotton with good thermal insulation effect, which can also reduce the noise.
    四、选择合适的空气过滤器系统。
    4、 Select the appropriate air filter system.
    五、生产设备选型也必须注意噪音问题。
    5、 Attention must also be paid to noise in the selection of production equipment.
    1、空调机房的位置:
    1. Location of air conditioning room:
    许多用户因地制宜或者想要节约投资成本,往往在食品厂净化车间的同一楼层的角落或者无尘室吊顶夹层划出一个区域作为无尘室空调机组机房,这样的做法无疑是错误的。
     实验室装修
    Many users adjust measures to local conditions or want to save investment costs. They often delimit an area in the corner of the same floor of the purification workshop of the food factory or the ceiling interlayer of the clean room as the air conditioning unit room of the clean room. This is undoubtedly wrong.
    首先,在靠近无尘室的位置设置机房,空调机房的通风性不好,对空调机组的运行以及制冷、通风效果均会收到影响。空调机房的噪音是无尘室的主要噪音来源,因此,将空调机房移到楼顶,或者离无尘室车间至少15米以外的位置。
    Firstly, the machine room is set near the dust-free room. The ventilation of the air conditioning machine room is not good, which will affect the operation of the air conditioning unit and the refrigeration and ventilation effects. The noise of the air conditioner room is the main noise source of the clean room. Therefore, move the air conditioner room to the roof or at least 15m away from the clean room workshop.
    2、别小看一些小型空气净化设备的噪音问题,一台FFU空气净化器的噪音可以控制在50db左右,要是局部要求相对较高的无尘室如百级无尘室、千级无尘室车间,也许要用到几十台或者几百台的FFU空气净化器,这样的噪音控制就相对较难了。可以选择采用德国进口EBM风机的FFU空气净化器,造价相对会高出一些,其净化效果以及使用寿命都比国产的离心风机要优胜一些,而且在噪音方面可以大力改善。
    2. Don't underestimate the noise problem of some small air purification equipment. The noise of an FFU air purifier can be controlled at about 50dB. If local clean rooms with relatively high requirements, such as class 100 clean rooms and class 1000 clean room workshops, dozens or hundreds of FFU air purifiers may be used, which is relatively difficult to control. The FFU air purifier with EBM fan imported from Germany can be selected, and the cost will be relatively higher. Its purification effect and service life are better than those of domestic centrifugal fans, and the noise can be greatly improved.
    3、通风管道的制作以及保温降低噪音。食品厂净化车间通风管道制作应该尽量减少不必要的弯头以及合理的设计通风管道变径可以有效降低噪音。通风管道制作完成后必须采用保温棉包裹,保温棉可以保护风管在使用过程中不结露,也可以有效降低通风管道系统运转时产生的噪音。
    3. The fabrication and thermal insulation of ventilation pipes reduce noise. The fabrication of ventilation duct in purification workshop of food factory should minimize unnecessary elbows and reasonable design of ventilation duct reducing can effectively reduce noise. After the ventilation duct is manufactured, it must be wrapped with thermal insulation cotton, which can not only protect the air duct from condensation during use, but also effectively reduce the noise generated during the operation of the ventilation duct system.
    4、置于食品厂净化车间生产设备的选型及采购,每个行业的生产线都不同。业主可以根据实际情况挑选适合自己的生产线设备。主要是要求厂家提供噪音相对较低的设备。
    4. For the selection and procurement of production equipment in the purification workshop of the food factory, the production lines of each industry are different. The owner can select suitable production line equipment according to the actual situation. It mainly requires manufacturers to provide equipment with relatively low noise.
