Introduction The basement has ventilation and smoke exhaust. I saw that the 1# and 2# power distribution rooms have exhaust and air supply, generators, high-end equipment, and the fire pump room only has exhaust and no exhaust. Why? First of all, the norm is just to

The basement has ventilation and smoke exhaust. I saw that the 1# and 2# power distribution rooms ha

First of all, the regulations only require that the rooms (or enclosures) in the basement should be supplied with air. If they are rooms with windows on the ground, they will not be supplied with air. Secondly, if they are all in the basement, the regulations also allow them to be in a fire protection zone. For air supply inside the building, that is, on the partition walls of high-end equipment and fire pump rooms, install 70° fire-proof air supply vents (normally exhaust air in the machine room), which will automatically close when the inlet air temperature is 70° to prevent the spread of fire.

What is the laying problem of diesel generator exhaust pipe?

The Fengmao diesel generator set is placed in the basement. There are flues in the basement rooms. The chimney of the Fengmao power generator set can be directly connected to the flue, or it can be an exhaust outlet. The thing to pay attention to is the problem of smoke seepage.

The heat dissipation and smoke exhaust of the generator set are all related to the diesel tank. Fire inspection only needs to look at these things of the generator set.

There are two commonly used methods of laying exhaust pipes: ① Horizontal overhead laying, which has the advantages of fewer turns and low resistance. The disadvantage is that it increases indoor heat dissipation and increases the temperature of the computer room; ② Ground trench The advantage of internal laying is that the indoor heat dissipation is small, but the disadvantage is that the exhaust pipe has many turns and the resistance is relatively large. Horizontal overhead laying is commonly used in high-rise buildings. The exhaust pipe should be led out separately to minimize elbows. The exhaust smoke temperature is between 350 and 5500c. To prevent burns and reduce radiant heat, the exhaust pipe should be insulated. Generally, there is no need for a suspended ceiling in the computer room. It does not matter even if the ceiling is 50-60 degrees, because the material of the suspended ceiling is non-combustible or difficult to burn. It should be noted that there should be a certain distance from other pipelines in the ceiling.
