1、 The newly built large air conditioning unit room shall be placed on the roof or 20m away from the dust-free room workshop.
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.
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.
4、 Select the appropriate air filter system.
5、 Attention must also be paid to noise in the selection of production equipment.
1. Location of air conditioning room:
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.
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. 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. 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. 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.
