Pressure delivery outlet in the room what effect positive outlet is pointing escape corridor air blower. It outdoor air pressure into the interior. When the building is on fire, it will produce a lot of smoke, carbon monoxide and other toxic gases and block line of sight, through positive pressure blower air to escape the fire stairs, indoor smoke can not reach the stairs, to create the conditions for people to escape. Positive pressure blower usually installed on top of buildings. Outlet pressure of the five kinds of building an effective way to set in today, we want to focus on an analysis of the relevant knowledge pressurized outlet pressure delivery outlet atlas, I believe this is the majority of users are more concerned about the knowledge of pressure delivery outlet set , let's look at the relevant specific outlet pressure setting method of building types in the hope that through our explanation so that everyone can better realize this: 1. Pressurized stairwell of the outlet should be used since the vertical louvers or positive pressure air outlet / multi-leaf smoke vents (body + panel form) positive outlet height when using positive pressure outlet (leafy row smoke vents), the chain should be provided with an electric fan is turned on its valve pressure fan of the suction pipe. Method 2. Pre-pressurized chamber outlet should be opened or automatic fire alarm linkage NC Grille open for on-site manual. Method 3. Mechanical pressure blower can set one or more. Pressurized air supply room should adopt the fire resistance of not less than 2.5 hours and 1.5 hours of wall and floor separated from the other parts of the pressure delivery outlet, the door on the wall should be Class A fire doors. Method 4. Mechanical pressure outlet of the wind speed of not more than 7m / s. Outlet section stairwell stairwell by the average of the total air volume calculation, 50% of the outlet section of the front room by the front room of the total air volume. Method 5. Antechamber mechanical pressure outlet should be set in the wall near the ground for more knowledge about the pressure blower and we will continue to bring you to organize, so stay tuned.
