Clean room, also known as clean workshop, clean room or clean room. The main function of clean room is indoor pollution control. Without clean rooms, mass production of pollution-sensitive components is impossible. The clean room should have a well-sealed space, and parameters such as air cleanliness, temperature, humidity, pressure, noise can be controlled according to needs. The problem of excessive noise may occur in the actual use of clean room air conditioning and ventilation equipment in the purification project, how to avoid it?

1, reasonable selection of air conditioning system ventilation technology equipment model.

When the noise can be controlled and the management requirements are high, low noise air conditioning and ventilation facilities should be selected. Under the same air volume and pressure, the noise produced by the centrifugal air conditioning and ventilation equipment with fins is smaller, while the noise produced by the centrifugal air conditioning and ventilation equipment with forward blades is larger.

2. The working point of air conditioning and ventilation equipment should be near the gaoxiao point.

The higher the efficiency of the same type of air conditioning and ventilation equipment, the lower the noise. In the clean room, in order to keep the working point of the air conditioning and ventilation equipment in the gaoxiao area of the air conditioning and ventilation equipment, it is necessary to avoid the use of valves to adjust the working conditions. If you need to set the valve at the exit of the air conditioning ventilation equipment, the best position is 1m away from the exit of the air conditioning ventilation equipment. It can reduce noise to below 2000 Hz. The air flow at the entrance of the air conditioning and ventilation equipment should be maintained evenly.

3. Where possible, appropriately reduce the speed of air conditioning and ventilation equipment.

The rotating noise of air conditioning ventilation equipment is proportional to the 10th square of the impeller circumferential speed, and the eddy current noise is proportional to the sixth power (or fifth power) of the impeller circumferential speed, so reducing the speed can reduce the noise.

4. When designing the ventilation management system, the clean room should minimize the pressure loss of the information system. When the total amount and pressure loss of the risk control system is large, it can be mainly divided into small systems.

5. The airflow speed in the clean room pipeline should not be too high.

The airflow speed in the clean room pipeline should not be too high to avoid social noise. Determining the airflow speed in the pipeline should be selected according to the different development requirements of the enterprise and relevant laws and regulations.

The above is the solution of ventilation equipment noise in clean room. Please follow us for more laboratory information.
