(8) The outdoor fire hydrant system of the conference building adopts a branch-shaped outdoor fire-fighting pipe network, and two outdoor fire hydrants are installed. The above-mentioned type of fire hydrant is used. The model of fire hydrant is SS100/65 type fire hydrant.
The indoor fire hydrant in the conference complex is made up of a water gun nozzle with a diameter of 19mm and a hose lined with a diameter of 65mm. The protection radius of the fire hydrants was 28.1m, spacing was 16.86m and 22.4m, and 6 risers were arranged.
The fire tank capacity is designed to be 18m³, the effective volume of the fire pool is 498.312m³, the fire pump head is 77m, and the flow rate is 55.46L/s.
(9) The automatic sprinkler system in the conference complex is a wet automatic sprinkler system with a fire hazard level of medium-risk class I. The nozzle spacing of the sprinkler system is 3.5m. The actual protection distance of each nozzle is 12.25 ㎡, and the design flow of the system is 1373.41L/min.
(10) The smoke exhaust design of the conference complex is a combination of natural exhaust and mechanical exhaust. On-ground buildings use natural exhaust fumes on each floor of stairwells, pre-combination rooms, walkways, and inpidual rooms to meet regulatory requirements. The underground floor uses mechanical smoke, which is pided into four smoke
partitions. The maximum amount of smoke emitted by the system is 114080.4 m³/h. The supplemental air volume of the supplementary air system must not be less than 5,7040.2 m3/h.
The exhaust fan uses a centrifugal fan, and a rectangular duct with a duct diameter or side length between 1220 and 1250 mm is selected.
(11) The conference complex needs to set up an automatic fire alarm system, adopts a centralized alarm system, and sets up a fire and security control center on the ground floor. The smoke detectors are used on the ground floor, the second floor, and on the third floor, and the temperature sensor is used on the first floor. There are 69 smoke detectors on the ground floor, 193 heat detectors on the first floor, 64 smoke detectors on the second floor, and 17 smoke detectors on the third floor.
A manual fire alarm button and a fire alarm are installed at the front room of elevator, the front room of the smoke prevention stairwell, and the middle of aisle of the conference building.
