Pressure delivery outlet in the fire industry, a prerequisite for security applications today we introduce to you some of the necessary conditions are positive outlet in the fire industry applications, only better understand the content of greater value to play to the positive outlet of value, I believe this is the majority of users are more concerned about the knowledge, let's take a detailed look at, as follows: For this knowledge we learned, positive outlet temperature sense smoke or manually fire alarm will turn on the air shaft pressurized air pressure delivery outlet, the front room of the stairs by a steady stream of pressurized air outlet will air on the front chamber, positive pressure fan automatically open the tower roof, the roof of the tower are pressure fan automatically open, positive outlet prices so that the front room to maintain a positive pressure to ensure the smoke will not spread in the region. Pressure delivery outlet parameters when the temperature is higher than 280 ° C were no longer escape the possibility of pressure delivery outlet set its internal fuse will blow, air automatically shut down to prevent the fire from spreading. Natural smoke of stairwell, it does not have the front room of natural smoke. More knowledge about the positive outlet and we will continue to bring you to organize, so stay tuned. Calculation method for determining the area of ??the building and the pressure delivery outlet size? Many of the buildings are equipped with pressure delivery outlet, but for high-rise buildings shared room pressure delivery outlet size determine how you can adjust the pressure delivery outlet size, and how to calculate the area, and for this knowledge you have How much better? Xiao Bian now for this problem for you specific analysis, allowing you to have a more positive outlet fully understood. The problem of computing positive outlet, it is your example to illustrate this, the top layer 34-storey building and basement set up two fan flow 25000m3 / h Total pressure 750pa speed 960r / min power 11kw elevator room on each floor closed style outlet 450 × (1600 + 250) stairwell with natural air, the method for calculating the above two questions? When building a fire electric pressure delivery outlet, this layer and the lower outlet opening. Therefore, the outlet air flow should be 1/3 of the total air volume. Outlet area of ??the outlet of the wind speed is determined according to the wind speed of not more than 7m / s, if the area of ??the opening does not come out so much, wind speed may also be controlled in 10m / s or less, attention tuyere block coefficient is generally 0.75 to 0.80, so the outlet area should be Calculated / coefficient, hope this knowledge will help you. For positive outlet do not understand what's next for your specific analysis of knowledge.
