In addition, in the case of large-scale high-rise buildings including underground spaces, it takes a lot of time to discharge smoke that rapidly spreads out of the building when a fire occurs, but the smoke inside the building is quickly transferred to the outside of the building through the ventilation function through ventilation control in real time. Can be discharged. Emergency lighting can guide the movement route to safely and quickly evacuate the building in case of an emergency, and it can secure enough visibility of evacuation personnel by having a quick ventilation function and improve the air quality inside the building. have.

Referring to FIGS. 1 to 7, a real-time ventilation control building integrated management system 10 with ventilation and emergency lighting functions includes an indoor air introduction passage 110, a first outdoor air introduction passage 120, and a rotational flow generator ( 200, a ventilation passage 310, a central discharge passage 320, an outer discharge passage 330, an indoor air discharge passage 410, a second outside air introduction passage 420, and a recovery passage 500 ), and a control unit 600, and an emergency lighting 800.

Air inside the building is sucked into the inlet side of the indoor air introduction channel 110 and flows to the outlet side. In the indoor air introduction channel 110, the inlet is exposed to a predetermined position in the interior space of the building to suck indoor air by a separate air conditioning means (not shown), and the outlet is connected to the inlet of the ventilation channel 310 to flow inside. One air may be discharged to the ventilation passage 310.

The indoor air introduction flow path 110 is connected to a first outside air introduction flow path 120 through which air outside the building is sucked. The first outside air introduction flow path 120 has an entrance exposed to a predetermined position outside the building to suck air outside the building by a separate air conditioning means, and the outlet is connected to the outer circumferential surface of the indoor air introduction flow path 110 to flow inside. Air may be discharged to the indoor air introduction passage 110. The first outside air introduction flow path 120 may include a separate opening/closing means (not shown) controlled by the control unit 600 to suck or block outside air according to the opening/closing operation of the opening/closing means.

The air inside the building flowing through the indoor air introduction passage 110 and the air outside the building sucked through the first outside air introduction passage 120 may be mixed. The mixed air may be discharged to the ventilation passage 310 through the outlet of the indoor air introduction passage 110.

Pollution in which the air sucked through the indoor air introduction flow path 110 and the first outside air introduction flow path 120 flows into the inlet side of the ventilation flow path 310 and has a relatively high concentration of suspended substances in the air introduced through the interior. Air is separated and discharged to the outside of the building, contaminated air is separated from the introduced air, and the remaining air is discharged to the indoor air discharge passage 410 through the outlet.

A rotational flow generator 200 is disposed at the inlet portion of the ventilation flow path 310. The rotational flow generator 200 may rotate the air discharged from the indoor air introduction channel 110 and introduced into the ventilation channel 310. The rotational flow generator 200 includes a support 210 extending from an inner circumferential surface of the ventilation passage 310 in a central direction, and a propeller 220 connected to an end of the support 210 and rotated by a separate power means (not shown). ) Can be provided. The air flowing in the ventilation flow path 310 and flowing in the linear direction passes through the rotational flow generator 200 and receives resistance from the rotating propeller 220 and proceeds toward the outlet of the ventilation flow path 310, It proceeds while rotating in the circumferential direction.

In this way, as the air introduced into the ventilation passage 310 rotates and flows, the suspended material contained in the air receives centrifugal force. In the rotating air, relatively heavy suspended substances may be collected toward the center side and relatively light suspended substances may be collected toward the outer side.

In the center of the ventilation flow path 310, a center discharge flow path 320 formed to be discharged to the outside of the building by introducing air at a central portion of the air rotating by the rotation flow generator 200 may be disposed. The central discharge passage 320 may pass through the ventilation passage 310 at an outlet portion of the ventilation passage 310 to be connected to the outside of the building. The inlet of the central discharge passage 320 is disposed at the central portion of the cross-section of the ventilation passage 310, and after sufficient rotational flow is formed by the rotational flow generator 200, the rotational flow generator 200 so that air in the central portion can be introduced. It is desirable to be placed at a sufficient distance from ). The central discharge passage 320 gently bends toward an inner circumferential surface of one side of the ventilation passage 310 toward the outlet portion of the ventilation passage 310 and penetrates the inner circumferential surface of one side of the ventilation passage 310 to reach the outlet portion of the ventilation passage 310. And the exit can be formed to be exposed to the outside of the building.

The central discharge passage 320 has air flowing toward the center among the air flowing between the central discharge passage 320 and the outer discharge passage 330 on the outer peripheral surface of the central discharge passage 320 surrounded by the ventilation passage 310. Blocks air from being discharged between the center discharge passage 320 and the outer discharge passage 330 from the inside of the central suction port 321 formed open to be joined to the central discharge passage 320 and the central discharge passage 320 A central guide member 322 may be provided that extends obliquely toward the inlet side of the central discharge passage 320 so as to surround the central suction port 321. Air flowing toward the center by the center guide member 322 formed obliquely toward the inlet side may be guided into the center discharge passage 320 through the center suction port 321.

In the vicinity of the inner circumferential surface of the ventilation passage 310, an outer discharge passage 330 formed to be discharged to the outside of the building by introducing air from an outer portion of the air rotating by the rotational flow generator 200 may be disposed. The outer discharge passage 330 is disposed along the inner circumferential surface of the ventilation passage 310 and is formed so that the inlet portion has an annular open cross-section so that only the air in the outer portion may be introduced.

The inlet of the outer discharge passage 330 is disposed on the inner circumferential portion of the cross section of the ventilation passage 310, and after sufficient rotational flow is formed by the rotational flow generator 200, the rotational flow generator 200 so that air from the outer portion can be introduced It is desirable to be placed at a sufficient distance from ). As shown in FIGS. 4 to 7, the outer discharge passage 330 is gradually blocked from the upper portion of the annular open cross-section toward the exit portion of the ventilation passage 310 and only the remaining lower portion is opened, and the remaining lower portion is the ventilation passage 310. ) Is gently bent toward the inner circumferential surface of the ventilation flow path 310, reaches the exit portion of the ventilation flow path 310, penetrates the inner peripheral surface of the ventilation flow path 310, and exposes the exit to the outside of the building.

The outer circumferential surface facing the center of the outer discharge passage 330 is formed open so that the air flowing toward the outer part of the air flowing between the outer discharge passage 330 and the central discharge passage 320 joins the outer discharge passage. It extends obliquely toward the inlet side of the outer discharge passage 330 to block air from being discharged between the population 331 and the outer discharge passage 330 and between the outer discharge passage 330 and the center discharge passage 320 The outer guide member 332 may be formed to surround the outer suction port 331. Air flowing toward the outer periphery by the outer guide member 332 formed obliquely toward the inlet side may be guided into the outer discharge passage 330 through the outer suction port 331.

The residual air discharged from the ventilation passage 310 is introduced into the indoor air discharge passage 410 and discharged back into the building. In the indoor air discharge passage 410, the inlet is connected to the outlet of the ventilation passage 310 so that the air that has passed through the ventilation passage 310 is introduced, and the outlet is exposed to a predetermined position in the interior space of the building by a separate air conditioning means. Air can be exhausted into the space inside the building.

A second outdoor air introduction channel 420 through which air outside the building is sucked may be connected to the indoor air discharge channel 410. In the second outside air introduction flow path 420, the entrance is exposed to a predetermined position outside the building to suck air outside the building by a separate air conditioning means, and the outlet is connected to the outer peripheral surface of the indoor air discharge flow path 410 to flow inside. Air may be discharged to the indoor air discharge passage 410. The second outside air introduction flow path 420 may include a separate opening/closing means (not shown) controlled by the control unit 600 to allow external air to be sucked or blocked according to the opening/closing operation of the opening/closing means.

In the second outside air introduction flow path 420, residual air flowing through the indoor air discharge flow path 410 and the outside air of the building sucked through the second outside air introduction flow path 420 may be mixed. The mixed air may be discharged to the interior space of the building through the outlet of the indoor air discharge passage 410.

The recovery passage 500 is connected to allow air to flow between the outlet portion of the indoor air discharge passage 410 and the inlet portion of the indoor air introduction passage 110. The recovery flow path 500 has an inlet formed at a portion of the indoor air discharge flow path 410 so that a part or all of the air flowing through the indoor air discharge flow path 410 can be sucked, and the outlet of the indoor air introduction flow path 110 is Air that is formed at the inlet portion and has already passed through the ventilation passage 310 at least once may be introduced into the ventilation passage 310 again. As will be described later, when the air quality of the indoor air introduced for the first time is significantly low or separation from the ventilation passage 310 is not sufficiently achieved, the entire process is repeated once or more to sufficiently increase the air quality of the indoor air and then rebuild the building. It can be discharged into the interior space.

The control unit 600 determines that the concentration of fine dust measured by the external fine dust sensor 710 disposed outside the building is measured by the first internal fine dust sensor 720 disposed at the entrance side of the indoor air introduction flow path 110. When the concentration is higher than the dust concentration, the first outside air introduction flow path 120 and the second outside air introduction flow path 420 are closed, and the fine dust concentration measured by the external fine dust sensor 710 is at the outlet side of the ventilation flow path 310. When the concentration of the fine dust measured by the arranged second internal fine dust sensor 730 is higher, the second external air introduction flow path 420 may be closed.

When the air quality of the external space of the building is lower than that of the internal space of the building, introduction of outside air has a rather negative effect. Therefore, the air quality can be improved by passing only the internal air through the ventilation passage 310 while the outside air is blocked. . In addition, when the air quality of the external space of the building is lower than the air quality of the air passing through the ventilation flow path 310 and is higher than the air quality of the space inside the building inputted into the indoor air introduction flow path 110, the first outside air introduction flow path 120 ), the indoor air may be primarily diluted by suctioning outside air, and the introduction of the outside air through the second outside air introduction passage 420 may be blocked to maintain improved air quality.

When the concentration of fine dust measured by the third internal fine dust sensor 740 disposed on the outlet side of the indoor air discharge passage 410 is higher than a predetermined reference value, the control unit 600 opens the collection passage 500 to provide indoor air. Some or all of the air flowing through the discharge passage 410 may be introduced into the indoor air introduction passage 110 through the recovery passage 500. In comparison with the air quality of the indoor space, the air having the fine dust concentration reduced below a certain standard value must be discharged back to the indoor space to improve the indoor air quality improvement efficiency.Therefore, even though the air has already passed through the ventilation passage 310 more than once, it is determined in advance. If the concentration of fine dust is higher than the reference value, the suspended matter may be further separated by collecting it again through the recovery passage 500. In particular, the controller 600 may cause the rotation flow generator 200 to generate a stronger rotational flow as the concentration of the fine dust measured by the first internal fine dust sensor 720 increases. Separation of the heavy floating material and the light floating material is further strengthened by the strong rotational flow, and thus can be discharged through the central discharge passage 320 and the outer discharge passage 330, respectively.

When a sudden fire occurs inside a building and smoke spreads rapidly, the controller 600 may detect it through an internal sensor and perform immediate ventilation. At this time, it is possible to quickly achieve ventilation by introducing a large amount of outside air, and at the same time, by turning on the emergency lighting 800 in the main passage inside the building, it is possible to ensure safe movement of personnel inside the building.

In particular, if a fire occurs in a high-rise building, apartment house, or shopping mall where a large number of people gather, it can cause a lot of damage, so it is possible to minimize the damage to people through the lighting of emergency lights along with the ventilation function. In the event of a fire, if smoke spreads rapidly inside the building, it is possible to ensure sufficient visibility of personnel in the building who could not be evacuated.

In addition, in the case of large-scale high-rise buildings including underground spaces, it takes a lot of time to discharge smoke that rapidly spreads out of the building when a fire occurs, but the smoke inside the building is quickly transferred to the outside of the building through the ventilation function through ventilation control in real time. Can be discharged.

Emergency lighting can guide the movement route to safely and quickly evacuate the building in case of an emergency, and it can secure enough visibility of evacuation personnel by having a quick ventilation function and improve the air quality inside the building. have.

As described above, according to the real-time ventilation control building integrated management system 10 having both ventilation and emergency lighting functions according to an embodiment of the present invention, by generating rotational flow, only the central side air and the outer side air are discharged to the outside of the building. It is possible to minimize energy efficiency reduction due to introduction of outside air by separating only the air in which suspended matter is concentrated temporarily, and by appropriately introducing outside air as needed according to the measurement value of fine dust at each location, air quality improvement efficiency can be increased. Accordingly, when the air quality is significantly lowered, it is possible to control ventilation and turn on emergency lights in real time, such as repeatedly performing an improvement process through the recovery flow path 500 or generating a more powerful rotational flow.
