Description

Split damper with integrated supply and exhaust {Partition type damper}

The present invention relates to a supply/exhaust integrated type split damper capable of simultaneously supplying and evacuating with only one damper by forming an air supply passage and an exhaust passage in a damper housing.

In general, a ventilation system is a device used to make indoor air comfortable by forcibly circulating indoor air and outdoor air such as large buildings or factories, and by driving a fan to introduce fresh air from the outside into the room. By discharging the contaminated air to the outside, it is possible to comfortably ventilate the air in the closed room.

Such a ventilation device is usually equipped with an electric damper. The main role of the electric damper is to block the flow path by closing the damper plate when the ventilation device is not driven to prevent external air from entering the room. Correspondingly, the damper plate is rotated through the drive motor to open the flow path, thereby supplying fresh air from the outside and exhausting the polluted air from the interior.

As described above, in the case of a ventilation system in which a damper is installed, an air supply damper that is connected to the supply air passage to introduce outdoor air into the interior, and an exhaust damper that is connected to the exhaust passage to discharge indoor air to the outside, respectively. It had to be installed and operated separately.

In the case of such a ventilation device, each damper having a different purpose and a control device for controlling the opening and closing of the dampers are required, and a complicated process is required, such as connecting each flow path and installing a bypass flow path.

Accordingly, the scale of the ventilation system was inevitably increased, the manufacturing process and installation were complicated, and the cost required accordingly was not small.

The configuration of the present invention has been described above. Hereinafter, the operation of the integrated air supply/exhaust type split damper according to the present invention having the above configuration will be briefly described.

5 and 6 illustrate the operation of the supply/exhaust mode and the bypass mode of the split damper of the supply/exhaust integrated type according to an embodiment of the present invention.

First, in the case of the supply and exhaust mode, in order to exhaust the contaminated air indoors and supply fresh air outside, the air supply motor 610 and the exhaust motor 620 are operated, respectively, and the air supply passage 11 and the exhaust passage ( 12) open.

When the air supply motor 610 is operated, as illustrated in FIG. 5, the air supply rotation shaft 340 connected to the air supply motor 610 rotates horizontally forward from a vertical state, and accordingly, the air supply passage 11 is opened, Air is supplied to the room as air flows into the room.

At the same time, as the exhaust motor 620 is operated and the exhaust rotation shaft 440 connected to the exhaust motor 620 also rotates, the exhaust damper plate 400 is also horizontally rotated forward, thereby opening the exhaust passage 12.

In this way, as the two flow paths of the air supply passage 11 and the exhaust passage 12 are simultaneously opened, fresh air from the outside is introduced into the room, and the contaminated air in the room is discharged to the outside, thereby ventilation is achieved.

Here, when only one of air supply or exhaust is performed depending on the selection, only one of the air supply motor 610 and the exhaust motor 620 is operated to open the corresponding flow path, so that only one flow path may be used.

On the other hand, when external ventilation is avoided and only internal circulation is to be performed on days when outdoor air is not good, such as when fine dust increases, as illustrated in FIG. 6, the air supply damper plate 300 and the exhaust damper plate 400 are closed. The bypass mode can be executed by opening the bypass damper plate 520 by operating only the bypass motor 630 while leaving it in the state.

In this bypass mode, the indoor air introduced into the exhaust passage 12 moves to the supply air passage 11 through the passage communication port 510, and then enters the room again and passes through a filter installed inside, thereby preventing internal circulation. Will come true.

As described above, in the divided damper according to the present invention, the air supply passage 11 and the exhaust passage 12 are integrally formed in the damper housing 100, and the air supply damper plate 300 and exhaust for opening and closing the air supply passage 11 By installing an exhaust damper plate 400 for opening and closing the flow path 12 and performing opening and closing according to the selection, it is possible to simultaneously perform air supply from one flow path and exhaust from the other flow path, so that the air supply damper and the exhaust damper are separately provided. Compared to the existing method, only one damper needs to be installed, so it is easy to install and saves cost and time.

In addition, since a bypass part is also provided, when internal circulation rather than general ventilation is performed, the air supply damper plate 300 and the exhaust damper plate 400 are rotated vertically to close the air supply passage 11 and the exhaust passage 12. By rotating the bypass damper plate 520 to open the flow path communication port 510, the internal air is introduced into the room after passing through the filter, thereby recirculating the indoor air in a clean state.

As described above, preferred embodiments of the present invention have been described in detail, but the technical scope of the present invention is not limited to the contents described in the above-described embodiments and drawings, and is modified by those of ordinary skill in the art.
