- Next, let's introduce in detail that in industrial production, clean rooms have become essential purification equipment. However, if not used properly, it can cause many factors that affect pressure fluctuations in clean rooms. Today, we will briefly introduce methods to prevent interference from pressure fluctuations in clean rooms.
1. When the indoor air conditioning system runs for a certain period of time, the resistance of the system increases when it reaches a certain value, which in turn affects the total air supply volume, causing the actual air supply volume to be less than the set air supply volume and unable to guarantee the original indoor pressure difference;
2. The resistance of the air conditioning system will change over time, mainly due to changes in the air supply caused by changes in the filter resistance, which affects the pressure difference in the clean room;
3. Due to the high personnel flow in the cleanroom, frequent opening of doors and windows can also lead to a decrease in the original sealing performance, ultimately affecting the existing pressure difference in the cleanroom.
What are our solutions to the above interference factors?
1. Adjust the fresh air valve;
2. Interlocking control of fans and air valves;
3. Adjust the return air valve or exhaust air valve;
4. Regularly replace necessary filters;
5. Install an air damping layer at the return air outlet;
6. The filtering equipment is installed on the downwind wall of the dust-free workshop, requiring sufficient residual air volume indoors.
