Also known as clean workshop, dust-free workshop is a room specially designed to remove air particles, harmful air, bacteria and other pollutants in a certain space, and control indoor temperature, indoor pressure, air flow speed and air distribution, noise, vibration, lighting and static electricity in a certain range.
One of the important factors to clean the indoor air is that the area of the air velocity around the performance of the clean room is the breeze, and the vulnerable people, such as machine movement and interference, become confused. Improving the wind speed can suppress the influence of interference and keep clean, but because the increase of the wind speed will affect the increase of the operation cost, the demand of the cleaning level that should be met can provide the most appropriate wind speed to achieve the appropriate Wind power supply to achieve economic benefits.
On the other hand, in order to achieve the stable effect of the clean room, it is also an important factor to keep the uniform air flow. If you can't maintain a uniform air flow, it means that the wind speed is different. Especially on the wall, the air flow will generate eddy current along the wall, so it is difficult to achieve high cleanliness.
Impact of wind speed on dust-free workshop:
Similar to the diffusion effect, when the filter material has static electricity, the longer the dust stays in the filter material, the easier it will be absorbed by the material. When the wind speed changes, the filtration efficiency of electrostatic materials will change significantly. If you know there is static electricity on the material, you should design your air conditioning system to reduce the amount of air passing through each filter.
According to the traditional theory, the smaller the wind speed is, the smaller the collision probability between dust and fiber is, and the lower the filtration efficiency is. But in practical application, this effect is not obvious, because the lower the wind speed is, the smaller the elasticity of fiber to dust is, and the dust is easier to adhere.
High wind speeds cause high drag. If the service life of the filter is based on the end resistance, high wind speed, the service life of the filter is short.
