Referring to FIGS. 1 and 2 , a ventilation device 100 according to an embodiment may include a case 110 , a heat exchange element 120 , and a separation member 130 . Furthermore, the ventilation device 100 may include a fluid accommodating part 140 .

First, the case 110 may be formed in various shapes. And the case 110 may include an internal accommodation space. Various components to be described later (heat exchange element, first and second filters, first and second fans, separation member, fluid accommodating unit, etc.) may be located in the accommodating space. Furthermore, the case 110 may include a cover CV. Accordingly, cleaning of components inside the case 110 can be easily performed by separating the cover CV or the like.

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 (one side), and the ventilation hole 113 and the air supply vent 114 may be disposed on one side (the other side). Hereinafter, the other side may be outdoors, and one side may be indoors. And in this specification, the first direction may correspond to a direction from the outside air outlet 111 toward the ventilation port 113 or a direction from the exhaust port 112 toward the air supply port 114 .

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. Accordingly, outside air may pass through the outside air supply unit 121 and the outside air discharge unit 122 of the heat exchange element 120 along the outside air outlet 111, and finally be introduced into the room through the air supply port 114. In addition, the bet in the room may pass through the vent 113 and pass through the bet supply unit 123 and the bet discharge unit 124 of the heat exchange element 120 in sequence and finally be discharged to the exhaust vent 122 . The first fan 141 is driven to discharge indoor air, that is, to the outside. In addition, the second fan 142 is driven to introduce outdoor air, that is, outdoor air into the room. Furthermore, in the case of cleaning, the second fan 142 is driven, and indoor air is discharged through the ventilation hole 113, the ventilation area R3, the outdoor area R1, the outdoor air supply unit 121 of the heat exchange element 120, and the outdoor air discharge. It passes through the unit 122 and can finally be re-introduced into the room through the air supply port 114. By such cleaning, moisture or water droplets generated in the heat exchange element 120 according to the inflow of outdoor air with high humidity may be removed by circulation of clean indoor air. In other words, moisture and moisture present in the outdoor air supply unit 121 of the heat exchange element 120 are removed by low-temperature or low-humidity indoor air introduced through the vent 113, and the indoor air is supplied through the air supply vent 114. may enter the room.

As an example, the case 110 may include an outside air area R1 , an air supply area R2 , a ventilation area R3 , and an exhaust area R4 .

The outdoor area R1 may communicate with the outdoor air vent 111 . Also, the air supply region R2 may communicate with the air supply port 114 . Also, the ventilation area R3 may communicate with the ventilation hole 113 . Also, the exhaust region R4 may communicate with the exhaust port 112 .

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 120 according to the embodiment may perform heat exchange while passing internal and external air crossing each other. For example, the heat exchange element 120 may be a used heat exchanger. Furthermore, contaminants such as germs and toxic substances other than heat exchange between exhaust air and supply air may not be mixed with each other. Furthermore, the outer layer of the heat exchange element 120 may be surrounded by a film for protection from bacteria and the like. For example, the film may have sterilizing power to remove bacteria and the like. For example, the film may contain a metal or a metal alloy. In addition, the heat exchange element 120 may include a metal or resin material, and may have, for example, a structure coated by adding or coating metal (gallium) and ions (eg, copper ions). The heat exchanging element 120 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 . The heat exchange element 120 may be made of metal or resin. Accordingly, the heat exchange element 120 may have strong durability due to moisture or the like. Furthermore, the heat exchange element 120 can be easily cleaned against moisture or the like. Thus, the problem of the ventilation device due to moisture can be suppressed. Furthermore, durability or reliability of the ventilation device 100 due to moisture or the like may be improved.

Referring further to FIG. 3 , the heat exchange element 120 is disposed in the case 110 and communicates with the outdoor air supply unit 121 communicating with the outdoor air outlet 111, the exhaust air port 112, the ventilation port 113, and the air supply port 114, respectively. ), a bet discharge unit 124, a bet supply unit 123 and an outside air discharge unit 122 may be included. That is, the heat exchange element 120 may include an outside air supply unit 121 , an inside air discharge unit 124 , an inside air supply unit 123 and an outside air discharge unit 122 .

At this time, the heat exchange element 120 is an outdoor air supply unit 121 (or outdoor air discharge unit) for supplying outdoor air (A) to the room and a bet supply unit (or bet discharge unit) for discharging indoor air (B) to the outside or outside. ) may be alternately stacked. In this case, heat exchange may occur through the heat exchange element 120 while outdoor air is supplied indoors and indoor air is discharged outdoors. Accordingly, the ventilation device 100 may provide improved energy efficiency. However, when the outdoor air moves along 'A' and the indoor air moves outdoors along 'B', there is no movement of moisture or bacteria between the outdoor air and the indoor air. That is, the heat exchange element 120 is made of resin rather than nonwoven fabric or paper, and only heat exchange between supply air and exhaust air can occur. Accordingly, when indoor air is polluted by a patient, an infected person, or the like, the indoor air may be discharged to the outdoors. Accordingly, indoor contamination can be easily prevented. Furthermore, since there is only heat exchange between supply air and exhaust air (no movement of moisture, bacteria, etc.), re-contamination of polluted indoor air is prevented in advance.

As such, the outside air supply unit (or outside air discharge unit) and the inside supply unit (or outside air discharge unit) may have a structure separated from each other. Furthermore, the outside air supply unit (or outside air discharge unit) and the bet supply unit (or bet discharge unit) may form different layers and have repeatedly formed valleys. Thus, heat exchange between the outside air through the outside air supply unit (or outside air discharge unit) and the outside air through the inside supply unit (or bet discharge unit) can be made. Furthermore, the outdoor air supply unit 121 may communicate with the outdoor area R1 to supply outdoor air A into the room. The outdoor air supply unit 121 also communicates with the outdoor air discharge unit 122 so that the outdoor air A can sequentially move to the outdoor air supply unit, the outdoor air discharge unit, the air supply area R2 and the air supply port 114 .

In addition, in order to discharge indoor air B to the outdoors, the supply unit 123 may communicate with the ventilation area R# and the ventilation hole 113. The bet supply unit 123 also communicates with the bet discharge unit 124, so that the indoor air B can sequentially move to the bet supply unit, the bet discharge unit, the exhaust region R4, and the exhaust vent 112.

Furthermore, as an embodiment, the outdoor air region R1 may communicate with the outdoor air supply unit 121 and the outdoor air vent 111 between the outdoor air supply unit 121 and the outdoor vent 111 . The air supply area R2 may communicate with the outside air discharge unit 122 and the air supply port 114 between the outside air discharge unit 122 and the air supply port 114 .

In addition, the ventilation area R3 may communicate with the bet supply unit 123 and the ventilation hole 113 between the bet supply unit 123 and the ventilation hole 113 . The exhaust region R4 may communicate with the exhaust outlet 124 and the exhaust port 112 between the exhaust outlet 124 and the exhaust port 112 .

Also, in the heat exchange element 120, the inflow or exchange of fluid according to air supply and exhaust is blocked. That is, except for energy exchange, fluid (moisture) in the air may not move inside the heat exchange element 120 . That is, all polluted indoor air may be discharged through the exhaust port. In other words, when the contaminated air is exhausted, some of the air may not flow out to the air supply path of the heat exchange element 120 . Likewise, fresh air from the outside can all be introduced through the supply port. In other words, when supplying clean air, some of the air may not leak through the exhaust path of the heat exchange element 120 . Thus, the health and welfare of people indoors can be improved.

In addition, in the ventilation device 100 according to the embodiment, the separating member 130 may be disposed between the outdoor vent 111 and the vent 113. The separation member 130 may be disposed between the outdoor area R1 and the ventilation area R3. Accordingly, the separating member 130 may partition the outdoor area R1 and the ventilation area R3.

Also, the separation member 130 may include a bypass portion 131 connecting the vent 113 and the outdoor vent 111 . The bypass unit 131 can be driven by a short wave valve. For example, the bypass unit 131 may open or close a hole through which the vent 113 and the outdoor vent 111 communicate with each other by manipulation. Accordingly, when the bypass unit 131 is opened, the ventilation area R3 and the outdoor area R1 may be connected to each other. When the bypass unit 131 is open, the outdoor outlet 111 may be in a closed state.

Furthermore, a damper may be installed in at least one of the vent 113, the exhaust vent 112, the outdoor vent 111, and the air supply vent 114. For example, a ventilation damper (not shown) may be installed in the ventilation hole 113 . An exhaust damper may be installed in the exhaust port 112 . An outside air damper may be installed in the outside air unit 111 . An air supply damper (not shown) may be installed in the air supply device 114 . For example, a short wave valve 111a may be installed in the outdoor outlet 111 . Thus, in the present specification, when the ventilation device is driven in 'clean' mode, the outdoor vent 111 may be closed. Accordingly, the indoor air introduced through the ventilation hole 113 passes through the bypass part 131 and is not discharged to the outside air vent 111, but is sequentially sent to the outside air supply part 121 and the outside air discharge part 122 of the heat exchange element 120. can move

At this time, the dampers installed in the outside air intake 111 and the ventilation hole 113 may be actuator dampers. The electric damper may include a vane that adjusts an opening degree of a passage through which air flows according to a rotational angle, and a damper actuator that operates the vane.

For example, the ventilator 100 may include a control unit CB. In addition, the control unit CB may control the opening degree of each damper by operating the damper actuator. An increase in the opening degree of the damper may mean that the damper is opened. A decrease in the opening degree of the damper may mean that the damper is closed.

By operating the damper actuator under the control of the control unit CB, the rotation angle of the vane may be controlled. As a result, intake of air through the outdoor vent 111 or the ventilation hole 113 can be controlled.

In addition, the dampers installed in the exhaust port 112 and the air supply port 114 through which air is discharged may be a Back Draft Damper (BDD). Accordingly, it is possible to prevent air from being sucked through the exhaust port 112 and the air supply port 114 .

Meanwhile, the controller CB may be installed in the case 110 . In more detail, the control unit CB may be installed on the side. An opening for installing a control unit may be formed on the side of the case 110, and the control unit CB may be installed in the opening for installing the control unit. The controller CB may be installed to protrude in an inner direction or an outer direction of the case 110 .

In addition, the controller CB may be installed on a side of the side on which the vent 113, the exhaust vent 112, the outside vent 111, and the air supply vent 114 are not formed. For example, when the ventilation hole 113 and the air supply hole 114 are formed on one side of the case 110 and the outside air hole 111 and the exhaust hole 112 are formed on the other side of the case 110, the control unit CB) may be disposed on a side other than one side/the other side of the case 110 .

The controller CB may include a communication unit, an interface unit, an inverter unit, and the like, and may control overall operation of the outdoor air treatment ventilator 100 .

Furthermore, a cooling/heating device or the like may be connected or disposed in the air supply region R2. That is, air supply AC for connecting or disposing cooling, heating, or cooling/heating devices may exist in the air supply region R2. With this configuration, air that has been cooled and heated can be introduced into the room.

Also, the ventilation device 100 may include a first fan 141 and a second fan 142 . The first fan 141 may be disposed in the exhaust region R4 to discharge internal air to the outside. The first fan 141 may be located adjacent to the exhaust port 112 .

That is, 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.

Also, the second fan 142 may be disposed in the air supply region R2. The second fan 142 may introduce outside air into the room. The second fan 142 may be positioned adjacent to the air supply port 114 .

Referring to FIGS. 4 and 5 , the ventilation device 100 according to the embodiment may further include a first filter F1 and a second filter F2. The first and second filters may include filters having various functions.

The first filter F1 may be attached to the heat exchange element 120 . The first filter F1 may be a pre filter. The first filter (F1) may be disposed in at least one of the outside air supply unit 121 and the inside supply unit 123.

The second filter F2 may be, for example, a HEPA filter. The second filter F2 may be disposed between the air supply port 114 and the heat exchange element 120.

Furthermore, as shown, in the ventilation device 100 according to the embodiment, the outdoor air is supplied through the outdoor air vent 111, the outdoor air area R1, the outdoor air supply unit 121 of the heat exchange element 120, the outdoor air discharge unit 122, and the air supply. It may be provided indoors by sequentially passing through the region R2 and the air supply port 114 (PAT1).

6 and 7, as shown in the ventilation device 100 according to the embodiment, the ventilation (indoor air) ventilation hole 113, the ventilation area R3, and the supply unit 123 of the heat exchange element 120 , it may be provided indoors through the exhaust unit 124, the exhaust region R4, and the exhaust port 112 in sequence (PAT2). The aforementioned FIGS. 4 and 5 refer to supply air in which outdoor air is introduced into the room. And FIGS. 6 and 7 mean exhaust from which polluted indoor air is discharged.

8 is a top view of an internal structure illustrating the flow of fluid according to the operation of the bypass unit in the ventilation device according to the embodiment, and FIG. It is a side view of the internal structure described.

Referring to FIGS. 8 and 9 , a case in which the ventilation device operates in a 'clean' manner is illustrated. As described above, the separation member 130 may be disposed between the outdoor outlet 111 and the ventilation port 113 . Also, the bypass unit 131 may operate as a damper. For example, when the bypass unit 131 is opened (or opened), indoor air is supplied to the ventilation hole 113, the ventilation area R3, the bypass unit 131, the outdoor area R1, and the outside air supply unit of the heat exchange element 120. 121, the outside air discharge unit 122, the air supply region R2, and the air supply port 114 may be sequentially moved.

Accordingly, indoor air may be circulated from the vent 113 to the air supply vent 111 . At this time, the indoor air may pass through the first filter F1 and the second filter F2 according to the above-described sequential movement. As a result, indoor air can be cleaned. Furthermore, the bypass unit 131 can be opened for a predetermined time while the outdoor vent 111 is closed, that is, during ventilation. That is, the bypass unit 131 may be open under certain conditions or for a certain period of time when the external outlet 111 is closed.

For example, when the degree of contamination of indoor air is measured, the controller may perform ventilation and cleaning according to the degree of contamination. For example, when the degree of contamination is greater than the highest first threshold value, exhaust/air supply may be performed. That is, indoor air may be discharged from the vent 113 to the exhaust vent 112 . However, when the degree of contamination is less than the first threshold value, the control unit may close the outdoor outlet 111 and open the bypass unit 131 . Accordingly, indoor air may flow into the room through the ventilation hole 113 , the heat exchange element 120 , and the air supply hole 114 . That is, indoor air can be cleaned by the first and second filters. Furthermore, when the degree of contamination is less than the first threshold value, the operating speed of the second fan 142 may be adjusted according to the degree of contamination. For example, even if the pollution level is less than the first threshold value, when the pollution level is similar to the first threshold value, the operation speed of the second fan 142 may be higher than when the pollution level is much smaller than the first threshold value. As such, the operating speed of the second fan 142 may be controlled in proportion to the degree of contamination.

Furthermore, when only the operation of the first fan 141 exists, pressure control between indoors and outdoors can be performed by the ventilation device. That is, the positive and negative pressure in the room can be adjusted. At this time, indoor air may be discharged through the vent 113, the heat exchange element 120, and the exhaust vent 112.

Accordingly, the ventilation area R3 and the outdoor area R1 may communicate with each other by the bypass portion 131 of the separating member 130 . Accordingly, indoor air introduced through the ventilation hole 113 may be supplied to the outdoor area R1. That is, when the bypass unit 131 is opened, indoor air or fluid can pass through the ventilation hole 113, the ventilation area R3, and the outside air area R1.

Air may be introduced into the outside air supply unit 121 of the heat exchange element 120 . Accordingly, moisture generated in the outdoor air supply unit 121 adjacent to an outdoor area having high temperature and humidity compared to the indoor area may be removed. That is, moisture generated in an area adjacent to the outdoors of the heat exchange element 120 may be easily removed by indoor air passing through the bypass unit 131 .

For example, some air may be discharged to the air supply port 114 through the outside air supply unit 121 and the outside air discharge unit 122 of the heat exchange element in the outside air region R1 . At this time, as described above, since the air passes through the first filter and the second filter, the degree of contamination of the air can be further lowered.

10 is a side view showing an internal structure of a ventilation device according to an embodiment, and FIG. 11 is a perspective view showing an internal structure of a ventilation device according to an embodiment.

Referring to FIGS. 10 and 11 , in the ventilation device according to the embodiment, the outdoor air supply unit 121 and the outdoor air discharge unit 122 of the heat exchange element 120 may be disposed to face each other. For example, they may communicate with each other and may be located opposite to each other with respect to the center of the heat exchange element.

In addition, the bet supply unit 123 and the bet discharge unit 124 of the heat exchange element 120 may also be disposed to face each other in the same way.

And, in an embodiment, the ventilation device 100 or the case 110 may further include a fluid receiving unit 140 disposed adjacent to the outside air supply unit 121 or the inside discharge unit 124.

The fluid accommodating unit 140 may be disposed to overlap an area adjacent to the outdoors among the heat exchange elements 120 . For example, the fluid accommodating unit 140 may be disposed to overlap the outside air supply unit 121 or the inside discharge unit 124 . That is, the fluid accommodating unit 140 may overlap the external air supply unit 121 or the internal discharge unit 124 in a third direction (Z-axis direction). The third direction may be a direction perpendicular to the first and second directions.

Furthermore, the internal discharge unit 124 may be disposed below the outdoor air supply unit 121 . For example, the internal air discharge unit 124 may overlap with the outdoor air supply unit 121 .

The fluid accommodating part 140 may be disposed under the discharge part 124 . Accordingly, the fluid accommodating unit 140 may overlap with the discharge unit 124 .

In addition, the internal discharge unit 124 may be disposed between the outside air supply unit 121 and the fluid receiving unit 140 . Accordingly, the fluid accommodating unit 140 may accommodate moisture (W) or fluid generated from an outdoor air supply unit or an indoor air discharge unit having a higher humidity or temperature than the heat exchange element 120 . For example, moisture generated in the outside air supply unit 121 of the heat exchange element 120 may move to the lower fluid accommodating unit 140 along the side surface of the heat exchange element 120 . Accordingly, moisture in the heat exchange element 120 is easily removed, and moisture in the ventilation device can be easily cleaned. For example, the moisture problem in the ventilation device can be easily solved by cleaning the fluid accommodating unit 140 . Accordingly, the durability of the ventilation device can be greatly increased. Furthermore, as described above, by the 'clean' operation, moisture mainly generated in the outdoor air supply unit 121 adjacent to the outdoor air in the heat exchange element 120 can be mostly removed by the flow of indoor air (ventilation port -> air supply port). . Accordingly, the use (eg, washing) of the fluid accommodating unit 140 may be greatly reduced. Accordingly, it is possible to provide a ventilation device that is free from moisture and has improved durability.

Furthermore, when a ventilation device is disposed inside the recess in a concrete layer located at the interface between each floor in a building such as an apartment building, the height of the recess can be reduced. In other words, by reducing the thickness of the ventilation device 100 according to the embodiment, the height or thickness of the concrete layer or recess may be reduced. Thus, the ceiling height between the ceiling and the floor 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 can be increased or the half height can 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.
