Common knowledge about air supply and exhaust in laboratory ventilation system
Ventilation system, air supply system differences?
Based on literal meaning, you can understand that they are used.
1. The ventilation system includes: air supply system, exhaust system, and smoke control system.
2. Planners usually plan the exhaust system and smoke prevention system together to save engineering costs.
3, usually under separate construction, such as the independent air supply system, exhaust system.
Differences and correlations between the exhaust system and the exhaust system in the fire protection system; does the exhaust system not be attributed to the fire system? Is the flue of the two systems shared? Is the fan independent? Can share, fans can not be shared independently. But the difference is high and low. The two did not have much effect.
What is the defined scale of firefighting fans? In a project, anti-exhaust smoke fans, positive pressure blowers, and blower fans, which are attributed to fire-fighting?
1. What is the defined scale of firefighting fans?
2, send exhaust, air conditioning duct attributed to the fire class duct it?
3. In an engineering, anti-exhaust smoke fan, positive pressure blower, exhaust fan (domestic fan, corridor exhaust, elevator room exhaust, room exhaust, etc.), which are attributed to the fire-fighting fan?
4. What is the definite scale of the exhaust pipe?
1, send exhaust air duct attributed to the fire class duct, air conditioning duct does not return.
2, the above except the corridor exhaust is not, all other fire-fighting fans. This resolution is very simple. You can see that all the fire-fighting linkage-operated fans on the weak current drawings are fire-fighting type. There is no linkage control for the fire-fighting type. It usually gathers first in the basement and on the roof.
What is a positive pressure blower: A blower that sends air to escape corridors sends air to the escape corridor at the time of the accidental attack, which is conducive to escape. When the air is supplied together, the pressure in the corridor is positive, which means that the pressure of the corridor is higher than other places. Smoke will not infiltrate and cause people to suffocate to ensure safety. Positive pressure blower: When an indoor fire occurs, the wind blocks the spread of smoke. (Oxygen deficiency, the effect of which is to give oxygen to some fire fighting channels. (Is it not to add oxygen to the fire?)
Exhaust fan: A fan used to remove smoke from a building during an accidental attack to improve sight in the building, remove smoke, and facilitate extinguishing. When there is an indoor fire, there will be a lot of smoke, and the effect is to discharge these smokes into the room. High-rise buildings (mostly used in the basement).
3, exhaust fan principle is equivalent to the exhaust fan?
Positive pressure fan, exhaust fan, exhaust fan, blower, make-up fan difference: blower = positive pressure fan = make up fan, the name is not the same as, with a variety of uses, transport gas temperature below 80 °C exhaust fan, a variety of uses , The exhaust gas fan with a gas temperature below 80°C is used for fire and smoke exhaust, and it is requested to run for 30 minutes at 280°C. It can also be used for kitchen exhaust fumes.
What is the relationship between the 4,70-degree fire damper and the 280-degree fire damper and the above fan?
280 degree fire dampers are used on fire smoke exhaust pipes, and fire retardant partitions are equipped with 70 degree fire dampers.
