The case 110 according to the embodiment may include a plurality of openings through which fluid (eg, air) is introduced or discharged. For example, the case 110 may include an outside vent 111 , an exhaust vent 112 , a ventilation vent 113 , and an air supply vent 114 .

Outdoor fluid, that is, outdoor air (OA), which is clean air, may be introduced into the outdoor outlet 111 . Exhaust air (EA), which is a contaminated fluid, may be discharged from the exhaust port 112 to the outdoor side. The ventilation hole 113 may introduce indoor fluid, that is, return air, which is a contaminated fluid. Supply air (SA), which is a clean fluid, may be discharged from the air supply port 114 to the indoor side.

In the case 110, the outside vent 111 and the exhaust vent 112 may be disposed on the other side, and the ventilation vent 113 and the air supply vent 114 may be disposed on one side. The other side may be outdoors, and one side may be indoors. In the present specification, the first direction may correspond to a direction from the ventilation hole 113 toward the outside air vent 111 or a direction from the air supply vent 114 toward the exhaust vent 112 .

The outdoor vent 111 may overlap at least a portion of the vent 113 in the first direction, and the exhaust vent 112 may overlap the air supply vent 114 at least partially in the first direction.

And, as shown, the first direction may correspond to the 'X-axis direction'. And the second direction (Y-axis direction) is a direction perpendicular to the first direction, and may correspond to a direction from the air supply port 114 toward the ventilation port 113 or a direction from the exhaust port 112 toward the outside air port 111. The third direction (Z-axis direction) may be a direction perpendicular to the first and second directions.

The case 110 according to the embodiment may be partitioned into each area so that fluids (internal or external air) introduced from the outside vent 111, the exhaust vent 112, the ventilation vent 113, and the air supply vent 114 do not mix with each other. there is. For example, spaces may be separated through various members.

In addition, in the case 110, an opening and closing portion is added to facilitate replacement, repair, or cleaning of heat exchange elements described later in areas other than the outside vent 111, the exhaust vent 112, the ventilation vent 113, and the air supply vent 114. can be mounted with

The heat exchange element according to the embodiment may perform heat exchange while crossing and passing internal and external air. The heat exchange element may perform heat exchange between the indoor air introduced from the ventilation hole 113 and the outdoor air introduced from the outdoor air vent 111 .

There may be a plurality of such heat exchange elements. As an example, the heat exchanging 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 between indoor and outdoor 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 external air.

Also, the second element 130 may perform heat exchange between indoor and outdoor air. For example, the second element 130 may be a sensible heat exchanger or a sensible heat exchange element. The second element 130 can absorb moisture and prevent deterioration.

The first element 120 and the second element 130 may be sequentially disposed in the first direction. Furthermore, the first element 120 and the second element 130 may not overlap each other in the second direction. As described above, the second direction may be parallel to a direction from the exhaust port toward the outdoor port.

The first element 120 may be made of a metal or resin material. Also, the second element 130 may be made of metal or polyethylene. Accordingly, the fluid (or air) may pass through both the first element 120 and the second element 130, and thus heat exchange and moisture exchange may occur. As a result, the heat recovery rate in the second element 130 may be improved. In addition, by removing moisture from the second element 130, problems caused by moisture can be suppressed. Furthermore, shape change due to fluid is suppressed, so that durability or reliability of the heat exchange element may be improved.

In addition, the ventilation device 100 includes a first filter 161 disposed between the ventilation hole 113 and the first element 120 and a second filter disposed between the outside vent 111 and the first element 120 ( 162) may be included.

The first filter 161 and the second filter 162 may at least partially overlap in the first direction (X-axis direction). That is, the vent 113 and the outdoor vent 111 may also be positioned correspondingly in the first direction (X-axis direction). In addition, the vent 113 and the outdoor vent 111 may overlap at least partially in the first direction (X-axis direction).

In addition, the ventilation device 100 includes a first damper 171 disposed between the first filter 161 and the first element 120 and a first disposed between the second filter 162 and the first element 120. 2 dampers 172 may be included.

The first damper 171 may be opened during cooling/heating. When the first damper 171 is opened, fluid may be supplied from the ventilation port 1131 to the air supply port 114 through the bypass passage. In addition, the second damper 172 may be opened during outdoor cooling. The first damper 171 and the second damper 172 may include a motor to rotate the damper door. Thus, the movement of the fluid can be selectively blocked.

The area of the first damper 171 may be smaller than that of the first filter 161 . Also, the area of the second damper 172 may be smaller than that of the second filter 162 . With this configuration, while performing heat exchange between indoor and outdoor air, a portion of indoor/outdoor air introduced through the first filter 161 and the second filter 162 flows into the room or ash as each damper is opened or closed. can be infiltrated.

The first filter 161 may be, for example, a purification filter. Thus, the first filter 161 can purify the polluted air in the room. And the second filter 162 may be formed of a filter that performs purification, dust collection, and deodorization. For example, the second filter 162 may include a plurality of filters. For example, the second filter 162 may be a pre/bag filter, and the first filter 161 may be a pre filter.

Furthermore, the ventilation device 100 includes a first fan 141 and an air supply port 114 disposed between the exhaust port 112 and the third element 150, and the second element 130 (or the third element 150). A second fan 142 disposed therebetween may be included.

The first fan 141 can easily exhaust air, and the second fan 142 can supply air. The first fan 141 and the second fan 142 may be manually/automatically operated by a user's manipulation or a system. The first fan 141 and the second fan 142 may form or accelerate the flow of the fluid by the rotation of the motor and blades by the motor. The first fan 141 operates for exhaust in the ventilation mode, and the second fan 142 may operate all the time.

In addition, the width W1 in the second direction in the space between the first filter 161 or the first filter 161 and the ventilation hole 113 is the third element 150 or the third element and the air supply hole 114 It may be smaller than the width W2 in the second direction in the space between the regions.

In addition, the width W3 in the second direction between the outdoor vent 111 and the first element 120 or the second filter 162 is in the second direction in the area between the exhaust vent 112 and the third element 150. may be smaller than the width W4. With this configuration, heat exchange between indoor and outdoor air can occur efficiently within the ventilation device 100 . Furthermore, air can be smoothly discharged to indoors and outdoors. Accordingly, an indoor user (eg, a person) can feel comfortable more quickly.

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

5 is a view explaining the flow of air in the ventilation device according to the first embodiment, FIG. 6 is a view explaining the flow of outside air in the ventilation device according to the first embodiment, and FIG. FIG. 8 is a view explaining the flow of bets by the bypass device in the ventilation device according to the first embodiment, and FIG. 9 is the first embodiment. It is a diagram explaining the effect on the bypass device in the ventilation system according to.

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 discharged (PAT2).

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

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

Referring to FIGS. 8 and 9 , the ventilation device 100 according to the embodiment may include a bypass unit DP, a bypass damper DP, and a sterilization device 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 a second direction (Y-axis direction).

Furthermore, when outdoor air has a lower temperature than indoor air, outside air having a relatively low temperature may be introduced into the room through the bypass unit BP.

As an example, the bypass damper DP may be opened so that the outside air introduced from the outside outlet 111 passes through the bypass unit BP without being supplied to the first element 120 . Conversely, when heat exchange with outside air is required, the bypass damper DP is closed to suppress the inflow of outside air through the bypass unit BP. Accordingly, when the bypass damper DP is closed, outside air is introduced into the room through the first element 120, and at this time, heat exchange or the like can be performed.

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

Furthermore, the ventilation device 100 according to the embodiment may further include a sterilization device 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 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, on/off of the sterilizer ST may be controlled according to a user's control. In addition, such a sterilization device can sterilize incoming air by using an ion cluster, a photocatalyst, and the like.

In addition, the sterilizer ST, the bypass unit BP, and the bypass damper DP may all be applied to the ventilation device according to the first embodiment described above or the second embodiment 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) and at least partially overlaps in the second direction (Y-axis direction). Accordingly, the thickness (100H) of the ventilation device can be minimized.

Accordingly, as shown in FIG. 9 , when the ventilation device 100 is disposed inside the recess RS in the concrete layer CC located at the boundary of each floor in a building such as a building or an apartment building, 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, the ceiling height between the ceiling (US) and the floor (BS) can be increased. Furthermore, the height of the half-go may be reduced. Here, the semi-goo 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 height may be reduced. As a result, since wastewater piping, ceiling air conditioners, ventilation devices, etc. are installed in the bango, the height or thickness of the ventilation device will be lowered and the floor height of the building (the total height of the roof of the building from the first floor of the building) will be lowered. can In particular, height reduction may be more effective for high-rise buildings. Furthermore, due to the decrease in floor height and floor height, the load of the building is reduced, and the reinforcing bar, wood material, labor cost, process period, and amount of concrete used in the building can be reduced. That is, the effect of reducing construction costs can be improved. Furthermore, issues such as height restrictions can be easily avoided by reducing the floor height, and the amount of waste during demolition can also be effectively reduced.

Referring to FIG. 10 , a ventilator 100A according to another embodiment may include a case 110 and a heat exchange element. In addition, as described above, the case 110 may include an outside vent 111 , an exhaust vent 112 , a ventilation vent 113 , and an air supply vent 114 .

Furthermore, in the ventilation device 100A according to the present embodiment, the heat exchanging element may include the first element 120, the second element 130, and the third element. In addition, the ventilation apparatus 100A may include the above-described first fan, second fan, first filter, second filter, first damper, and second damper. Except for the contents described below, the above contents may be equally applied.

The first element 120 and the second element 130 may be sequentially arranged in the first direction (X-axis direction). The first direction may correspond to a direction from the ventilation hole 113 toward the exhaust hole 112 .

Furthermore, along the first direction (X-axis direction), the vent 113, the first element 120/second element 130, and the exhaust vent 112 may be sequentially disposed.

Also, the first element 120 and the second element 130 may be sequentially arranged in the second direction (Y-axis direction). Furthermore, the first element 120 and the second element 130 may not overlap each other in the first direction. As described above, the second direction may be parallel to a direction from the exhaust port toward the outdoor port.

In the present embodiment, since the first element 120 and the second element 130 are sequentially arranged in the first direction, a heat exchange area of the fluid may be increased compared to the ventilator according to the first embodiment. Thus, energy efficiency can be improved. In contrast, in the ventilator according to the first embodiment, since the first element and the second element are disposed side by side in the second direction and the total length decreases in the first direction, miniaturization can be easily achieved.
