Description

Ventilation and Fire spread preventing system of multi-story building}

The present invention relates to a ventilation and fire spreading prevention system of a multi-story building, and more particularly, to continuously inject fresh air from each floor in a multi-story building such as an office, a neighborhood living facility, and a multi-unit house (apartment). To ensure that the flow of air in the multi-storey building is always made from the top to the bottom, and always maintains a comfortable air quality by the fresh air from outside, toxic gas and smoke generated in the indoor area in case of emergency such as fire emergency stairs The present invention relates to a ventilation and fire spreading prevention system of a multi-storey building, which is configured to prevent invasion of a fire so that evacuators can evacuate safely without difficulty in breathing.

Typically, multi-storey buildings are equipped with fire fighting equipment to extinguish the fire in the event of a fire.

It is intended to suppress fires in buildings, and evacuees are installed to move quickly to the rooftop or lower floors of a non-flame building and to safety zones. It is encouraging not to use an elevator that can not be understood, but to use an emergency staircase.

Therefore, in case of fire, evacuation of building should use emergency stairs through emergency exit.

On the other hand, in the event of a fire of a building such as a large high-rise apartment or a building, a large-scale human injury is caused by the smoke generated during combustion.

These smokes have a relatively less direct risk of human injury than flames and toxic gases generated immediately after combustion.However, smoke is the main cause of human injury in the event of fire. This is because the area spreads rapidly to the evacuation area as well as the area, which makes it difficult to evacuate quickly through the evacuation area such as emergency stairs.

Specifically, referring to Figure 1, the emergency staircase constituting the conventional multi-storey building 10 forms a ventilation window at the top of the natural ventilation method, and naturally the air of the emergency stairway is discharged to the outside through the upper ventilated I have a system.

Therefore, when a fire occurs, the gas and smoke generated in the indoor area according to the flow of air naturally flows into the emergency stairs along with the hot fire and spreads upward.

Therefore, if the fire occurred on the sixth floor, evacuators below the sixth floor are able to escape through the emergency stairs, but evacuators above the seventh floor are difficult to escape to the emergency stairs due to the incoming smoke and fire. A problem occurs.

In order to solve this problem, Utility Model Publication No. 20-2007-0001065 discloses a technology under the name of 'the method and apparatus for the use of the air curtain device using the air curtain device'.

Referring to FIG. 2, the outdoor air inlet 61 for air supply is provided on the roof, and a vertical air supply duct 12 and a horizontal air supply duct 12-1 are provided inside the building, and an auxiliary room 32 is provided on each floor of a high-rise building. When the air curtain device 41 is operated in case of fire by installing an air curtain device 41 connected to the horizontal air supply duct 12-1 in the smoke control area boundary (upper inner door entrance), the air curtain device 41 is blown in from the outside air inlet 61. The outside air is discharged to the air curtain device discharge port through the vertical air supply duct 12 and the horizontal air supply duct 12-1, and the air curtain (air membrane) formed by the discharge pressure of the discharged air at this time Or it proposes a method for the control of high-rise buildings, such as apartments and office buildings, characterized in that the smoke generated in the corridor directly to prevent the smoke entering the room 32.

That is, the air curtain device 41 connected to the outside air inlet 61, the vertical air supply duct 12, and the horizontal air supply duct 12-1 is installed at the boundary of the smoke control area of the floor smoke control area of each floor. It has been disclosed as a smoke control device, it can be seen that the installation of an air curtain to prevent the toxic gas generated in the interior of the building to enter the auxiliary room or emergency stairs.

In addition, it can be seen that the indoor air, such as the living room 31, is discharged to the roof exhaust fan 21 through the discharge damper 23 and the vertical discharge duct 22.

However, the prior art as described above may cause a problem that it is difficult to supply power to the air curtain equipment installed on each floor due to the interruption of the power when a fire occurs, and if a fire occurs in the air curtain equipment due to a possible explosion in the event of a fire Emergency staircases on floors present a problem that is difficult to use.

In addition, many evacuees have to be installed in a narrow and wide area to pass through the door to the room or emergency stairs, there was a problem that the enormous operating costs that occur.

In addition, since the outside air inlet 61 and the exhaust blower 21 are located close to each other, the wind emitted from the air curtain device 41 during the fire may cause toxic gas and smoke induced outside to be discharged through the exhaust blower 21. It must be included, the air containing these toxic gases and smoke enters the accessory room 32, the people evacuated to the accessory room 32 will have difficulty drinking breathing toxic gas.

In other words, referring to FIGS. 1 and 2 again, in the prior art, when a fire occurs, a stack effect occurs in an emergency staircase, and the emergency staircase becomes like a chimney, and smoke, toxic gas, and flames spread on the rooftop. Toxic gas is sucked back into the installed outside air inlet 61 and enters the air curtain device 41 connected to the horizontal air supply duct 12-1, causing difficulty in breathing.

For example, in 2017, fires in the UK caused smoke and toxic gases to rise, creating a situation in which smoke could suffocate even when evacuated to the roof.

Therefore, there is no need for a separate ancillary room 32 for each floor, and the air flow spreads from the upper part of the multi-story building to the lower part of the floor, and the ventilation and fire spreading can be easily performed and the ventilation can be easily performed using the emergency stairs. A prevention system is required.
