Smoke extraction machine room: a technical room where smoke extraction fans are installed for fire protection. The function of the smoke exhaust fan is: When a fire breaks out in the basement, a large amount of smoke is generated. At this time, the fire smoke exhaust fan starts to remove smoke from the fire area. Additionally, the smoke exhaust fan can also be used to reduce the air in the basement.
Fan room: the technical room where the fan is installed. If the air supply fan is installed on the roof of a high-rise building and supplies air to the stairwell or elevator front room through the duct well, it is called air supply. positive pressure air. Its function is also to supply air to the stairwell or. front room of the elevator when a fire breaks out upstairs. Guarantor of asafe evacuation.
How to carry out the noise reduction project in the computer room?
The most standardized approach should be to build an air collection chamber on the side of the ventilation shaft in the civil air defense zone. The partition between the ventilation shaft and the civil air defense zone (i.e. the civil air defense zone). empty wall of civil air defense) must be in double anti-fan door mode (select 2 BFM0176-15). During normal ventilation, the door is always open, and the air duct does not pass directly through the empty wall, but directly passes through the brick wall of the air collection room without installing a box. This is currently the most standardized approach. If the conditions are not met, for example there is not enough space for an air collection chamber, the exhaust room is too small, etc., then the onlyThe option is to install steel boxes on adjacent walls. general air ducts are of very large diameters. In addition to installing the boxes, in wartime it is necessary to seal the air ducts. That is, in wartime, normal air ducts are dismantled and steel plates are welded to both sides of the box to install waterproofing. .

It is best to find a professional manufacturer to complete the computer room noise reduction project . Relatively speaking, Losay Acoustics is. more professional. This manufacturer specializes in computer rooms. I have been working on noise reduction and sound insulation projects for many years and have a lot of experience in this field. The R&D team is also very professional and can provide reliable sound for computer rooms. insulation projects. Our computer room sound insulation project is carried out by this manufacturer. He's really good. Their sound insulation project should also be more comprehensive, which can effectively help eliminate noise in the computer room. by this manufacturer is also relatively reasonable.

Oil smoke shafts and air shafts on the unnatural layer are not counted in the building area, but the elevator machine room on the roof is a natural layer when oil smoke sinks and air. the shafts are attached to the exterior wall of the roof elevator machine room. The surface area of the building is also not calculated.
According to the new national standard - "Real Estate Measurement Code", the building area is not calculated in 10 cases. The 10 situations include: 1. Mezzanines, inserts, technical floors and cellars and a half-basements with a floor height of less than 2.20 meters. 2. Components, accessories, decorative columns, decorative glass curtain walls, columns, legs, steps and columnless canopies that highlight the walls of the house. 3. There are no air corridors between houses. 4. The roof of the house, the balcony, the sky garden and the swimming pool. 5. The operating platform, loading platform and space platform in the building as well as the space platform for placing crates and tanks in the building. 6. The lower floors of arcades and crossing buildings are used for the passage of roads and alleys. 7. Use houses with access bridges, overpasses, viaducts and sidewalks as roof structures. 8. Prefabricated houses. 9. Expansion joints between houses that are not connected inside the house. 10. It is understood that the new real estate measurement standards will allow for ranges of errorur of ±0.26, ±0.6 and ±1.4 according to different precision levels, while the old standard allows an area measurement error of 1.4.
