Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system using a ventilation duct,

The present invention relates to a ventilation system using a ventilation duct, and more particularly, to a ventilation system using a ventilation duct for ventilation of an elevator hall by using a ventilation duct installed in a building for use in a fire as a ventilation system, And a ventilation system capable of improving the ventilation function together with the function.

Generally, large buildings are moved to high-rise through elevators, and each floor is divided into several generations (or offices) so that they can live together. In particular, households (or offices) in residential areas are individually or integrally configured to allow heating and heating facilities.

However, the elevator hall is not covered by the ventilation regulations. In other words, Article 11, Paragraph 1 of the Rules on Facility Standards of Buildings is stipulated as follows.

"Article 11 (Standards for ventilation facilities for apartment buildings and multi-use facilities, etc.) (1) A house or building falling under any of the following subparagraphs (hereinafter referred to as" new apartment house, etc. ") newly built or remodeled pursuant to Article 87 (2) ) Shall be provided with natural ventilation or mechanical ventilation to allow ventilation of more than 0.7 times per hour.

1. Apartment for more than 100 households (excluding dormitory)

2. When a house is built with the same structure as a facility other than a house,

However, the portion to be ventilated here is limited to the indoor, that is, the residential space (or the office), and the ventilation regulation does not apply to the elevator hall or the staircase for a while. Here, the elevator hall means a shared portion including a passage to each residential space (or office) when it is lowered from the elevator.

Since the elevator hall is a shared part and is not included in the ventilation target in terms of equipment, there are many cases in which facilities for ventilation and the like are not provided when the building is newly constructed or remodeled.

Therefore, when the food waste goes down to the lower level, it can smell or shed. In the case of the elevator hall, since the ventilation is not properly performed, the odor remains for a long time, which is one of the factors causing discomfort.

Also, in the case of an elevator hall, there are many cases where a window is not made from the beginning for ventilation or a window is made so that it can not be opened and made like a window glass. As a result, dust and the like are always accumulated in the elevator hall. In the case of a child or an elderly person, such dust may cause respiratory diseases such as bronchitis and asthma.

Especially, in case of respiratory diseases, exposure to such respiratory diseases may occur when exposed to a long period of time in a closed elevator hall regardless of the season, such as the pollen season, the wet summer season, and the low humidity season.

There is no legal regulation as a method to solve such a problem, but there is also a case where a ventilation system is constituted in an elevator hall as a convenience facility of a resident. However, in this case, since the sale price has to be increased as well as a separate ventilation system has to be constructed, it is troublesome to prepare all of the introduction and construction of the ventilation system from the design stage. (1) Korea registered patent No. 1174689 (registered on August, 2012), (2) Korean registered patent No. 1227319 (registered date: 2013.01.22), (3) 1319067 (Registered on Oct. 10, 2013).

Therefore, various equivalents It should be understood that water and variations may be present.

1, the ventilation system using the ventilation duct according to the first embodiment of the present invention uses a ventilation duct (D) installed as a ventilation system of a building, and when a fire does not occur, So that it can be utilized as a ventilation duct in an elevator hall.

Accordingly, not only the structure of the ventilation system becomes simple, but also the ventilation effect in the elevator hall and the ventilation effect can be improved as well.

Hereinafter, this configuration will be described in more detail as follows.

First, as shown in FIG. 1, the ventilation system according to the present invention is mounted on a multi-story building divided into a staircase A, an elevator hall B and a residential space C. Here, the elevator hall B usually refers to a shared portion required to go down from the elevator into the residential space C. A fire door (FD) is provided between the staircase (A), the elevator hall (B) and the residential space (C) to prevent fire spread and smoke prevention.

Further, the multi-story building is provided with a ventilation duct (D) as a ventilation facility. In particular, the ventilation duct (D) is usually installed in a shared area portion where the elevator hall (B) or the elevator is installed. The smoke damper (D) is provided with an automotive pressure damper (AD) and an air supply fan (SF).

Here, the automotive pressure damper AD is provided for each elevator hole B so that noxious gas is not introduced into the staircase A or the elevator hall B from a place where a fire occurs in the event of a fire, (B) is maintained at a predetermined pressure so as to block the inflow of harmful gas.

The air supply fan SF refers to a fan used to supply outside air to the elevator hall B through the ventilation duct D to generate pressure and air volume required for ventilation as described above.

In the present invention, the ventilation hole 10, the exhaust fan 20, the opening / closing damper 30, and the composite damper 21 are further formed in the ventilation duct D.

The ventilation holes 10 are formed one by one for each elevator hall B and serve as passages for discharging the inside air from the elevator hall B to the outside through the ventilation duct D. [

The exhaust fan 20 operates when it is determined that ventilation is necessary. The ventilation fan 20 is provided with a composite damper 21 so that the inside air can be automatically discharged to the outside according to the ventilation amount required in the elevator hole B. The exhaust fan 20 may be installed in parallel with the air supply fan S or at various positions such as the middle of the length of the ventilation duct D or the end opposite to the air supply fan S. However, it is preferable that such an exhaust fan 20 is installed on the roof layer while being opposite to the air supply fan S, so that the interior of the elevator hall B containing contaminated or foreign materials can be discharged to the upper side of the building.

Particularly, the composite damper 21 is installed at the end of the ventilation duct D and interlocked with the operation of the automotive pressure damper AD according to the opening and closing of the fire door FD to prevent overpressure of the elevator hall B It is possible to prevent the fire door (FD) from being opened or closed when the elevator hall (B) is overpressurized) and the smoke wind speed (wind speed for blocking the inflow of the harmful gas into the elevator hall (B) It is open to the public and becomes a channel of ventilation.

The opening / closing damper 30 is mounted on the side of the air supply fan S to adjust the supply of the airflow in the ventilation duct D so as to increase the ventilation effect in supplying and ventilating the air volume necessary for obtaining a ventilation effect when a fire occurs.

The ventilation system using the ventilation duct constructed as described above operates as shown in the following Table 1 at the time of fire occurrence (ventilation effect) and at a normal time (ventilation effect).

First, both the air supply fan S and the opening and closing damper 30 are turned "OFF " during ventilation (normal). As a result, one end of the smoke duct (D) becomes clogged, and in this state, the exhaust fan (20) is operated while opening the compound damper (21). At the same time, the vent of the elevator hall (B) can be discharged through the ventilator (10). As a result, the exhaust air is sucked from the exhaust fan 20, so that the air in each elevator hole B flows into the ventilation duct D through the ventilation hole 10, and is discharged to the outside of the building.

On the other hand, in case of a fire, the pressure inside the elevator hole (B) must be maintained high through the air supply fan (S) so that harmful gas or the like from the place where the fire is generated is discharged from the place where the fire occurs to the hallway, stairs, .

Thus, the air supply fan S and the opening / closing damper 30 are turned ON, and outside air is introduced into the elevator hall B. At this time, the composite damper 21 is set to the "ON" state, and the automatic damper 21 is automatically closed according to the pressure state of the elevator hall B The pressure control is performed by opening and closing to obtain a ventilation effect.

Then, the ventilation hole 10 is made to be in the "OPEN" state so that outside air can be introduced into the elevator hall B through the air supply fan S, thereby helping to generate pressure necessary for ventilation.

Lastly, the automotive pressure damper AD is in the "ON" state, so that outside air supplied from the air supply fan S can be introduced into the elevator hall B to generate pressure necessary for ventilation. Since the automotive pressure damper AD has already performed a primary function as a smoke-free facility, its detailed description is omitted here.

As described above, according to the present invention, by using the ventilation duct provided in the building as a ventilation facility, not only the entire construction of the ventilation system can be simplified, but also space utilization can be improved by reducing the construction space.

In addition, according to the present invention, since the outside air can be introduced into the elevator hall through the ventilation hole when the fire occurs, the pressure in the elevator hall can be increased in a short time, thereby enhancing the effect of ventilation.

The ventilation system using the ventilation duct according to the second embodiment of the present invention is a system for applying to a case where a window W capable of being opened and closed is provided in a staircase A of a building as shown in FIG. Here, the configuration of the second embodiment is the same as that of the first embodiment, but the sub air supply fan 20 'replaces the exhaust fan 20 of the first embodiment, and the fire door FD and the window W ) In the opening /

Therefore, for the sake of convenience of explanation, the detailed description will be omitted here and only the configuration of the second embodiment other than the first embodiment will be described here.

Unlike the first embodiment, the sub-supply fan 20 'supplies outside air to the ventilation duct (D) and supplies it to the elevator hall (B) side so that ventilation can be performed. In this case, the remaining configuration except for the fire door (FD) and the window (W) constituting the second embodiment is the same as that of the first embodiment, and a description thereof will be omitted here.

First, at the time of ventilation, the sub damper fan 20 'is turned "ON" and the compound damper 21 is opened. Since the air supply fan S and the opening and closing damper 30 are turned OFF, the outside air flows into the elevator hall B by the operation of the sub-supply fan 20 '. At this time, since the fire door FD and the window W are opened, the outside air is discharged from the elevator hall B through the staircase A and the window W to the outside of the building.

Unlike the first embodiment, the outside air is supplied to the elevator hall B and then circulated to the outside of the building, thereby enhancing the ventilation effect.

On the other hand, at the time of a fire, since the sub-supply fan 20 'is turned off, the compound damper 21 is turned on, and both the fire door FD and the window W are closed, The smoke inducing effect is obtained by the operation.

In the preferred embodiment of the present invention, the sub-supply fan 20 'is preferably installed on the roof side. This is for supplying the cleaner outside air on the roof side to the elevator hall B so as to further enhance the ventilation effect.
