Smoke prevention effect of multi-leaf positive pressure air outlet

　　What is the smoke prevention effect of the multi-leaf positive pressure air outlet

　　Multi-leaf positive pressure air supply outlet is when the exhaust air volume of the multi-leaf positive pressure air supply outlet is constant, moderately reducing the cross-section of the multi-leaf positive pressure air supply outlet is beneficial to improve the actual smoke prevention effect of the multi-leaf positive pressure air supply outlet. Under the condition that the exhaust air volume of the positive pressure air outlet and the positive pressure air outlet are constant, increasing the aspect ratio of the multi-leaf positive pressure air outlet is beneficial to improve the actual smoke prevention effect of the multi-leaf positive pressure air outlet.

　　When installing the multi-leaf positive pressure air outlet, the natural environment for its installation must be cleaned up. If there are compartments and decoration ceilings, they should also be cleaned and tidy together to prevent future blockage of the smoke exhaust system ducts.

　　It is also very important to check the sealing performance of the multi-leaf positive pressure air supply outlet. If the sealing performance is not good, but a fire accident occurs, the multi-leaf positive pressure air supply air outlet breaker is blown, and the dust is still sent along the multi-leaf positive pressure. The vent spreads, which in turn leads to the spread of the fire.

　　Although the sealing performance is no problem, the credibility of the multi-leaf positive pressure air outlet should be vigilant when it is closed. After the temperature sensor transmits the posture, the multi-leaf positive pressure air outlet should be closed automatically and reliably.

　　In addition, everyone should also check that the gaps between the blades of a lot of leaf positive pressure air outlets or between the blades and the baffle are not many. This can be related to the actual effect of the application of the multi-leaf positive pressure air outlet.
