There may be a plurality of such heat exchange elements. In an embodiment, the heat exchange element may include a first element 120 , a second element 130 , and a third element 150 .

The first element 120 may perform heat exchange and moisture exchange with respect to the bet and the outside air. For example, the first element 120 may be a total heat exchanger or a total heat exchange element. The first element 120 may further improve heat exchange efficiency by performing secondary heat exchange with the outside air.

And the second element 130 may perform heat exchange with respect to the bet and the outside air. For example, the second element 130 may be a sensible heat exchanger or a sensible heat exchange element. The second element 130 may absorb moisture and prevent deterioration.

By this configuration, heat exchange can occur efficiently in the ventilation device 100 of the bet / outside air. Furthermore, the air can be smoothly discharged to the indoor and outdoor areas. Accordingly, an indoor user (eg, a person) may feel comfortable more quickly.

Further, the width W3 between the external device 111 and the first element 120 or in the second direction of the second filter 162 is the second of the region between the second damper 172 and the first element 120 . It may be larger than the width W5 in two directions. This may be the same as the area of the second damper 172 .

5 and 6, in the ventilation device 100 according to the embodiment, the bet is discharged to the air supply port 114 or the exhaust port 112 (PAT1), and the outside air is discharged to the exhaust port 112 or the air supply port 114. May be released (PAT2).

In addition, the ventilation device 100 may further include a bypass passage through which the bet is provided as an air inlet. Accordingly, the bet may be provided to the third element 150 through the first filter 161 and the first damper 171 . Also, the bet may be provided directly to the third element 150 through the first filter 161 . In an embodiment, in the bypass flow path, the flow of the bet may occur through the opening and closing of the first damper 171 .

The third element 150 according to the embodiment may be a heat pump for cooling/heating. That is, the third element 150 may be a refrigerant heat exchanger. With this configuration, the ventilation device 100 according to the embodiment can maximize energy efficiency.

The third element 150 may be disposed between the air supply port 114 and the first element 120 as described above.

In addition, the third device 150 may be disposed in a region between the first filter 161 and the first device 120 . Also, the third element 150 may not overlap the first filter 161 in the first direction.

8 and 9 , the ventilation apparatus 100 according to the embodiment may include a bypass unit DP, a bypass damper DP, and a sterilizer ST.

The bypass unit BP may be positioned adjacent to the first device 120 and the second device 130 . For example, the bypass unit BP may not overlap the first element 120 and the second element 130 in the first direction (X-axis direction). Furthermore, the bypass unit BP may overlap the first element 120 and the second element 130 in the second direction (the Y-axis direction).

Further, when the outside air has a lower temperature than the outside air, when the relatively low temperature outside air is introduced into the room, the outside air may be introduced through the bypass unit BP.

In an embodiment, the bypass damper DP may be opened so that the external air introduced from the external device 111 may pass through the bypass unit BP without being provided to the first element 120 . Conversely, when heat exchange with the outside air is required, the bypass damper DP may be closed to suppress the inflow of the outside air through the bypass unit BP. Accordingly, when the bypass damper DP is closed, outside air flows into the room through the first element 120 , and heat exchange may be performed at this time.

That is, when heat exchange with the outside air is not required (cooling through the outside air), the bypass damper DP may be opened, and the outside air may be introduced into the room through the air supply port 114 of the third element 150 .

Furthermore, the ventilation apparatus 100 according to the embodiment may further include a sterilizer ST. The sterilizer ST may be disposed between the second element 130 and the air supply port 114 . The sterilizer ST may perform sterilization when the outside air introduced into the room passes through the bypass unit BP or the first and second elements 120 and 130 .

Furthermore, when outside air is introduced through the bypass unit BP, the on/off of the sterilizer ST may be controlled according to the user's control. In addition, such a sterilizer may perform sterilization of the incoming air using an ion cluster, a photocatalyst, or the like.

In addition, the sterilizer ST, the bypass unit BP, the bypass damper DP, and the like may all be applied to the ventilation device according to the first embodiment or the second embodiment to be described later.

In addition, as described above, the bypass unit BP does not overlap the first and second elements 120 and 130 in the first direction (X-axis direction), but at least partially overlaps in the second direction (Y-axis direction). Accordingly, it is possible to minimize the thickness (100H) of the ventilation device.

Accordingly, when the ventilation device 100 is disposed inside the recess RS in the concrete layer CC located on the boundary surface of each floor in a building, such as an apartment building, as shown in FIG. 9, the height of the recess RS is increased. can be reduced In other words, by reducing the thickness 100H of the ventilation device 100 according to the embodiment, the height or thickness of the concrete layer CC or the recess RS may be reduced. Accordingly, it is possible to increase the ceiling height between the ceiling (US) and the floor (BS). Furthermore, the height of the vango may be reduced. Here, the bango may be a space or area between the ceiling and the upper floor or the floor of the upper floor. In other words, by the ventilation device according to the embodiment, the ceiling height of the building may be increased or the half height may be reduced. As a result, since wastewater pipes, ceiling-type air conditioners, ventilation devices, etc. are installed in the Bango, the height or thickness of the ventilation system decreases, thereby lowering the floor height of the building (the total height of the roof layer from the first floor of the building). can In particular, height reduction may be more effective for high-rise buildings. Furthermore, the load of the building is reduced due to the reduction of the height and the floor height, and the rebar, wood materials, labor cost, process period, and amount of concrete used in the building can be reduced. That is, the effect of reducing the construction cost may be improved. Furthermore, by reducing the floor height, issues such as height restrictions can be easily avoided, and the amount of waste during demolition can also be effectively reduced.

Accordingly, energy efficiency can be improved. On the other hand, in the ventilation device according to the first embodiment, the first element and the second element are arranged side by side in the second direction so that the overall length is reduced in the first direction, so that miniaturization can be easily achieved.
