Referring to FIGS. 1 and 2 , the ventilation device 100 according to the embodiment may include a case 110, a heat exchange element 120, a separation member 130, and a second bypass unit 151. Furthermore, the ventilation device 100 may include a fluid receiving portion 140.

First, the case 110 may have various shapes. And the case 110 may include an internal accommodation space. Various components described later (heat exchange element, first and second filters, first and second fans, separation members, fluid receiving units, etc.) may be located in the receiving space. Furthermore, case 110 may include a cover (CV). Accordingly, cleaning of the components inside the case 110 can be easily performed by removing the cover CV, etc.

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

Outdoor fluid, that is, clean air (Outdoor Air, OA), may be introduced into the outdoor device 111. Exhaust air (EA), a contaminated fluid, may be discharged to the outdoor side through the exhaust port 112. The ventilation hole 113 allows indoor fluid, that is, return air, which is a contaminated fluid, to flow in. The supply air (SA), which is a clean fluid, can be discharged indoors through the supply opening 114.

In the case 110, the external opening 111 and the exhaust opening 112 may be placed on the other side (one side), and the ventilation opening 113 and the air supply opening 114 may be placed 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 external opening 111 toward the ventilation opening 113 or a direction from the exhaust opening 112 towards the air supply opening 114. Alternatively, the first direction may be a direction from the other side to one side.

The external outlet 111 may overlap at least partially with the ventilation opening 113 in the first direction, and the exhaust opening 112 may overlap at least partially with the air supply opening 114 in the first direction.

And the first direction may correspond to the 'X-axis direction' as shown. And the second direction (Y-axis direction) may correspond to a direction perpendicular to the first direction from the supply opening 114 to the ventilation opening 113 or from the exhaust opening 112 towards the external opening 111. The third direction (Z-axis direction) may be perpendicular to the first and second directions.

Case 110 according to the embodiment may be divided into respective areas to prevent fluids (internal or external air) flowing in from the external device 111, the exhaust port 112, the ventilation port 113, and the supply port 114 from mixing with each other. there is. For example, space may be separated through various members. Accordingly, the outside air may pass through the outside air supply part 121 and the outside air discharge part 122 of the heat exchange element 120 along the outside mechanism 111, and finally be introduced into the room through the air supply opening 114. In addition, the indoor air may pass through the ventilation opening 113, sequentially through the air supply unit 123 and the internal air discharge unit 124 of the heat exchange element 120, and finally be discharged through the exhaust port 112. The first fan 141 is driven to exhaust indoor air, that is, air, to the outside. In addition, the second fan 142 is driven to allow outdoor air, that is, outside air, to flow into the room. Furthermore, in the case of cleaning, the second fan 142 is driven, and indoor air is discharged through the ventilation port 113, the ventilation area (R3), the outside air area (R1), the outside air supply unit 121 of the heat exchange element 120, and the outside air exhaust. It passes through the unit 122 and can finally be re-introduced into the room through the air supply opening 114. Due to this purification, moisture or water droplets generated in the heat exchange element 120 due to the inflow of outdoor air with high humidity can 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 ventilation opening 113, and the indoor air flows through the supply opening 114. It may enter the room.

In an embodiment, the case 110 may include an outdoor air area (R1), an air supply area (R2), a ventilation area (R3), and an exhaust area (R4).

The outdoor air area R1 may be in communication with the external device 111 . Additionally, the air supply area R2 may be in communication with the air supply opening 114. Additionally, the ventilation area R3 may be in communication with the ventilation opening 113. And the exhaust area R4 may be in communication with the exhaust port 112.

In addition, an opening and closing part is added to facilitate replacement, repair, or cleaning of the heat exchange element described later in areas other than the exterior device 111, the exhaust port 112, the ventilation port 113, and the supply port 114 in the case 110. It can be implemented as .

The heat exchange element 120 according to the embodiment may perform heat exchange while internal and external air crosses each other. For example, the heat exchange element 120 may be a thermal heat exchanger. Furthermore, contaminants such as bacteria, toxic substances, etc. other than heat exchange between exhaust and supply air may not mix with each other. Furthermore, the outer layer of the heat exchange element 120 may be surrounded by a film for protection from bacteria, etc. For example, the film may have sterilizing power to remove bacteria, etc. For example, the film may contain a metal or metal alloy. Additionally, the heat exchange element 120 may include a metal or resin material and, for example, may have a structure coated by adding or coating a metal (gallium) and an ion (e.g., copper ion). The heat exchange element 120 may perform heat exchange between the internal air flowing in from the ventilation opening 113 and the external air flowing in from the external air opening 111. This heat exchange element 120 may be made of metal or resin. Accordingly, the heat exchange element 120 may be highly durable due to moisture, etc. Furthermore, the heat exchange element 120 can be easily cleaned against moisture, etc. Accordingly, problems with ventilation devices due to moisture can be suppressed. Furthermore, durability or reliability of the ventilation device 100 due to moisture, etc. may be improved.

Referring further to FIG. 3, the heat exchange element 120 is disposed within the case 110 and communicates with each of the external air outlet 111, the exhaust port 112, the ventilation port 113, and the air supply port 114. ), it may include an internal air discharge unit 124, an internal air supply unit 123, and an external air discharge unit 122. That is, the heat exchange element 120 may include an external air supply unit 121, an internal air discharge unit 124, an internal air supply unit 123, and an external air discharge unit 122.

At this time, the heat exchange element 120 includes an external air supply unit 121 (or external air discharge unit) that supplies outdoor air (A) into the room, and an internal air supply unit (or internal air discharge unit) that discharges indoor air (B) outdoors or to the outside. ) can be stacked alternately. At this time, 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 can provide improved energy efficiency. However, as outdoor air moves along 'A' and indoor air moves outdoors along 'B', there is no movement of moisture, bacteria, etc. between outdoor air and indoor air. That is, the heat exchange element 120 is made of resin rather than non-woven fabric or paper, so that only heat exchange can occur between the supply air and exhaust air. Accordingly, when indoor air is polluted by patients, infected people, etc., the indoor air may be discharged outdoors. Accordingly, indoor pollution can be easily prevented. Furthermore, since there is only heat exchange between the supply air and exhaust air (no movement of moisture, bacteria, etc.), re-contamination of polluted indoor air is prevented in advance.

In this way, the external air supply unit (or external air discharge unit) and the internal air supply unit (or internal air discharge unit) may have separate structures. Furthermore, the external air supply unit (or external air discharge unit) and the internal air supply unit (or internal air discharge unit) form different layers and may have repeatedly formed valleys. Accordingly, heat exchange can be achieved between the outside air through the outside air supply unit (or outside air discharge unit) and the inside air through the inside air supply unit (or inside air discharge unit). Furthermore, in order to supply outdoor air (A) indoors, the outdoor air supply unit 121 may communicate with the outdoor air area (R1). In addition, 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 exhaust unit, the air supply area R2, and the air supply opening 114.

Additionally, the indoor air supply unit 123 may communicate with the ventilation area R# and the ventilation port 113 in order to discharge the indoor air B to the outdoors. And 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 area (R4), and the exhaust port 112.

Furthermore, in an embodiment, the outdoor air area R1 may communicate with the outdoor air supply unit 121 and the external device 111 between the external air supply units 121 and the external device 111. The air supply area R2 may communicate with the outdoor air outlet 122 and the air supply port 114 between the outdoor air outlet 122 and the air supply port 114.

In addition, the ventilation area (R3) may communicate with the internal air supply unit 123 and the ventilation hole 113 between the internal air supply unit 123 and the ventilation hole 113. The exhaust area (R4) may communicate with the internal air discharge unit 124 and the exhaust port 112 between the internal air discharge unit 124 and the exhaust port 112.

In addition, the heat exchange element 120 blocks the inflow or exchange of fluid due to supply and exhaust. That is, except for energy exchange, fluid (moisture) in the air may not move inside the heat exchange element 120. In other words, all contaminated indoor air can be discharged through the exhaust port. In other words, when exhausting contaminated air, some of the air may not flow out into the air supply path of the heat exchange element 120. Likewise, all fresh air from outside can be brought in through the supply vent. In other words, when clean air is supplied, some of the air may not leak out to the exhaust path of the heat exchange element 120. Accordingly, the health and welfare of people indoors can be improved.

Additionally, in the ventilation device 100 according to the embodiment, the separation member 130 may be disposed between the external device 111 and the ventilation hole 113. The separation member 130 may be disposed between the outdoor air area (R1) and the ventilation area (R3). Accordingly, the separation member 130 may partition the outdoor air area (R1) and the ventilation area (R3).

And the separation member 130 may include a first bypass portion 131 connecting the ventilation hole 113 and the external device 111. The first bypass unit 131 may be driven by a short-wave valve. For example, the first bypass unit 131 can open or close a hole communicating with the ventilation port 113 and the external device 111 by manipulation. Accordingly, when the first bypass unit 131 is opened, the ventilation area R3 and the outdoor air area R1 may be connected to each other. When the first bypass unit 131 is open, the external mechanism 111 may be in a closed state.

The second bypass unit 151 may be driven by a short-wave valve. For example, the second bypass unit 151 can open or close the hole by manipulation. Accordingly, when the second bypass unit 151 is opened, the exhaust area R4 and the outside air area R1 may be connected to each other.

The second bypass unit 151 may be disposed between the exhaust port 112 and the heat exchange element 120. Furthermore, the second bypass unit 151 may overlap the external air supply unit of the heat exchange element 120 in the first direction. This will be explained later.

Furthermore, the second bypass unit 151 may be disposed between the first fan 141 and the external air supply unit 121 of the heat exchange element 120. Accordingly, the exhaust area R4 and the outside air area R1 are connected to each other by the second bypass unit 151, so that clean and negative pressure, which will be described later, can be performed.

Furthermore, a damper may be installed in at least one of the ventilation opening 113, the exhaust opening 112, the external opening 111, and the air supply opening 114. For example, a ventilation damper (not shown) may be installed in the ventilation opening 113. An exhaust damper may be installed in the exhaust port 112. An external air damper may be installed in the external mechanism 111. An air supply damper (not shown) may be installed in the air supply opening 114. For example, a short-wave valve 111a may be installed in the external device 111. Accordingly, in this specification, when the ventilation device is operated in 'clean' mode, the external device 111 may be closed. Accordingly, the indoor air flowing into the ventilation opening 113 is not discharged to the external appliance 111 through the first bypass unit 131, and is not discharged to the external air supply unit 121 and the external air discharge unit 122 of the heat exchange element 120. You can move sequentially.

At this time, the damper installed in the external device 111 and the ventilation hole 113 through which air is sucked may be an electric damper (actuator damper). The electric damper may include a vane that adjusts the opening degree of a flow path through which air flows depending on the rotation angle, and a damper actuator that operates the vane.

For example, the ventilation device 100 may include a control unit (CB). Additionally, the control unit (CB) can control the opening degree of each damper by operating the damper actuator. An increase in the damper opening may mean that the damper is open. A decrease in the damper opening 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 can be controlled. As a result, intake of air through the external device 111 or the ventilation hole 113 can be controlled.

Additionally, the damper installed at the exhaust port 112 and the supply port 114 through which air is discharged may be a back draft damper (BDD). Therefore, it is possible to prevent air from being sucked through the exhaust port 112 and the supply port 114.

Meanwhile, the control unit (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 the 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 control unit CB may be installed to protrude toward the inside or outside of the case 110.

Additionally, the control unit (CB) may be installed on a side of the side where the ventilation opening 113, the exhaust opening 112, the external opening 111, and the air supply opening 114 are not formed. For example, if the ventilation opening 113 and the air supply opening 114 are formed on one side of the case 110, and the external opening 111 and the exhaust opening 112 are formed on the other side of the case 110, the control unit ( CB) may be placed on a side other than one side/other side of the case 110.

The control unit (CB) may include a communication unit, an interface unit, an inverter unit, etc., and may control the overall operation of the outdoor air treatment ventilation device 100.

Furthermore, cooling and heating equipment, etc. may be connected or placed in the air supply area R2. That is, air (AC) for cooling, heating, or cooling/heating equipment to be connected or disposed may exist in the air supply area (R2). With this configuration, cooled and heated air can be introduced into the room.

Additionally, 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 area R4 to exhaust 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 can be operated manually/automatically by user operation or by the system. The first fan 141 and the second fan 142 can form or accelerate the flow of fluid through a motor and rotation of wings by the motor. The first fan 141 operates for exhaust in ventilation mode, and the second fan 142 may operate at all times.

And the second fan 142 may be disposed in the air supply area (R2). The second fan 142 may introduce outside air into the room. The second fan 142 may be located adjacent to the air supply opening 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 with 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 external air supply unit 121 and the internal air 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 opening 114 and the heat exchange element 120.

Furthermore, as shown, in the ventilation device 100 according to the embodiment, the outside air is supplied to the outside device 111, the outside air area (R1), the outside air supply part 121 of the heat exchange element 120, the outside air discharge part 122, and the supply air. It can be provided indoors through the area (R2) and the air supply opening (114) sequentially (PAT1).

Referring to Figures 8 and 9, a case where the ventilation device operates in 'clean' mode is shown. As described above, a separation member 130 may be disposed between the external device 111 and the ventilation hole 113. And the first bypass unit 131 may operate as a damper. For example, the first bypass unit 131 is opened (or opened) so that indoor air flows into the ventilation port 113, the ventilation area (R3), the first bypass unit 131, the outside air area (R1), and the heat exchange element 120. ) of the outdoor air supply unit 121, the outdoor air discharge unit 122, the air supply area (R2), and the air supply port 114 can be moved sequentially (PAT3).

Accordingly, indoor air can be circulated from the ventilation opening 113 to the air supply opening 114. At this time, the indoor air may pass through the first filter (F1) and the second filter (F2) according to the sequential movement described above. Accordingly, indoor air can be purified. Furthermore, when the external device 111 is closed, that is, when ventilation is performed, the first bypass unit 131 can be opened for a predetermined period of time. That is, the first bypass unit 131 may be open under certain conditions or for a certain time when the external device 111 is closed.

For example, when the pollution level of indoor air is measured, the control unit can perform ventilation and cleaning according to the level of pollution. For example, if the degree of contamination is greater than the first greatest threshold, exhaust/supply air may be performed. That is, indoor air may be discharged from the ventilation port 113 to the exhaust port 112. However, if the contamination level is less than the first threshold, the control unit may close the external device 111 and open the first bypass unit 131. Accordingly, indoor air may be introduced into the room through the ventilation opening 113, the heat exchange element 120, and the air supply opening 114. That is, indoor air can be purified by the first and second filters. Furthermore, when the degree of contamination is less than the first threshold, the operating speed of the second fan 142 may be adjusted depending on the degree of contamination. For example, even if the degree of contamination is less than the first threshold, when the degree of contamination is similar to the first threshold, the operating speed of the second fan 142 may be greater than when the degree of contamination is much smaller than the first threshold. In this way, the operating speed of the second fan 142 can 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 achieved by a ventilation device. In other words, the positive and negative pressure in the room can be adjusted. At this time, indoor air may be discharged through the ventilation port 113, the heat exchange element 120, and the exhaust port 112.

Accordingly, the ventilation area R3 and the outside air area R1 may be communicated with each other by the first bypass part 131 of the separation member 130. Accordingly, indoor air flowing into the ventilation opening 113 may be provided to the outdoor air area R1. That is, when the first bypass unit 131 is opened, indoor air or fluid can pass through the vent 113, the ventilation area (R3), and the outside air area (R1).

And air may flow 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 the outdoors, where temperature and humidity are higher than indoors, can be removed. That is, moisture generated in an area adjacent to the outdoors of the heat exchange element 120 can be easily removed by indoor air passing through the first bypass unit 131.

For example, some air may be discharged from the outdoor air region R1 through the outdoor air supply unit 121 and the outdoor air discharge unit 122 of the heat exchange element to the air supply opening 114. At this time, as described above, the pollution level of the air can be further reduced because it passes through the first filter and the second filter.

FIG. 10 is a side view showing the internal structure of a ventilation device according to an embodiment, and FIG. 11 is a perspective view showing the 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 exhaust unit 122 of the heat exchange element 120 may be arranged to face each other. For example, they may communicate with each other and be located oppositely based on the center of the heat exchange element.

In addition, the internal air supply unit 123 and the internal air discharge unit 124 of the heat exchange element 120 may also be arranged to face each other.

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

The fluid receiving portion 140 may be arranged to overlap an area of the heat exchange element 120 adjacent to the outdoor area. For example, the fluid receiving unit 140 may be arranged to overlap the external air supply unit 121 or the internal air discharge unit 124. That is, the fluid receiving unit 140 may overlap the external air supply unit 121 or the internal air discharge unit 124 in the third direction (Z-axis direction). The third direction may be perpendicular to the first and second directions.

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

The fluid receiving portion 140 may be disposed below the inner discharge portion 124. Accordingly, the fluid receiving portion 140 may overlap with the internal fluid discharge portion 124.

Additionally, the internal air discharge unit 124 may be disposed between the external air supply unit 121 and the fluid receiving unit 140. Accordingly, the fluid receiving part 140 can accommodate moisture (W) or fluid generated from the outdoor air supply part or the internal air discharge part on the outdoor side where the humidity or temperature is higher than that of the heat exchange element 120. For example, moisture generated in the external air supply part 121 of the heat exchange element 120 may move to the lower fluid receiving part 140 along the side of the heat exchange element 120. Accordingly, moisture in the heat exchange element 120 can be easily removed, and moisture in the ventilation device can also be easily cleaned. For example, the moisture problem within the ventilation device can be easily solved by cleaning the fluid receiving portion 140. Accordingly, the durability of the ventilation device can be greatly increased. Furthermore, as described above, by 'clean' operation, most of the moisture generated in the outdoor air supply unit 121 adjacent to the outdoor air in the heat exchange element 120 can be removed through the flow of indoor air (ventilation port -> supply port). . Accordingly, the use (eg, cleaning) of the fluid receiving part 140 can be greatly reduced. As a result, it is possible to provide a ventilation device with improved durability and free from moisture.

FIG. 12 is a diagram of an internal structure illustrating the flow of fluid during one operation mode in the ventilation device according to the embodiment, and FIG. 13 is a diagram illustrating the internal structure of the fluid flow during one operation mode of the ventilation device according to the embodiment. This is a side view of the structure.

According to the embodiment, Figures 12 and 13 show a case where the ventilation device operates in 'clean' mode. Referring to FIGS. 12 and 13 below, the names of these operation modes (e.g., clean, clean, etc.) may be referred to by different terms or words, but will be described below based on the names described in the specification.

When the ventilation device operates in 'clean' mode, the second fan 142 is stopped and the upper part of the first fan 141 is opened to remove the contaminants of the filter due to the supply air by opening and closing the upper part of the first fan 141. can be discharged. Accordingly, when the second fan 142 introduces outside air into the room, the dust from the filter in the direction of travel is opened in the second bypass unit 151, so the air flows in the opposite direction and the dust from the filter is discharged. And the second bypass unit 151 may operate as a damper as described above. In particular, the second bypass unit 151 may be open. And the first bypass unit 131 may operate as a damper. For example, the first bypass unit 131 may be driven open (or open) or closed (or closed). This operation is performed when the ventilation device operates in 'clean' mode at each user's input or preset condition/time, and the control unit operates the first bypass unit 131, the second bypass unit 151, and the first fan 141. ), the control signal can be transmitted to the second fan 142, etc.

Accordingly, the fluid flows through the supply port 114, the air supply region (R2), the outside air discharge section 122 of the heat exchange element 120, the outside air supply section 121 of the heat exchange element 120, the second bypass section 151, You can move to the exhaust area (R4). Furthermore, as a result of the first fan 141, the fluid flows into the outside air discharge part 122 of the heat exchange element 120, the outside air supply part 121 of the heat exchange element 120, the second bypass part 151, and the exhaust area. You can move to (R4) (PAT4).

Accordingly, foreign substances such as dust and dead bodies placed on the first filter (F1) on the outside air supply unit (121) of the heat exchange element (120) may move to the exhaust port (112) or exhaust area (R4). Accordingly, the fluid introduced through the external device 111 can be efficiently introduced into the external air supply unit 121 of the heat exchange element 120. In other words, a phenomenon in which the amount of fluid passing through the external air supply unit 121 or the first filter F1 of the heat exchange element 120 is reduced due to the foreign matter can be suppressed. Alternatively, the problem of foreign substances accumulating or accumulating in the outside air supply unit 121 of the heat exchange element 120 or the first filter F1 on the outside air supply unit 121 due to air supply (inflow of fluid into the room) can be solved.

As described above, the second bypass unit 151 may overlap the external air supply unit 121 of the heat exchange element 120 in the first direction (X-axis direction). Accordingly, the above-described foreign matter removal can be effectively performed.

FIG. 14 is a diagram of an internal structure illustrating the flow of fluid during different operation modes in the ventilation device according to the embodiment, and FIG. 15 is a diagram illustrating the internal structure of the fluid flow during different operation modes in the ventilation device according to the embodiment. This is a side view of the structure, and Figure 16 is a modified example of Figure 14.

Referring to Figures 14 and 15, when the ventilation device operates in the 'negative pressure' mode, fluid flows through the ventilation port 113, the internal air supply part 123 of the heat exchange element, the internal air discharge part 124 and the exhaust port 112 of the heat exchange element. ) is sequentially moved, and the supply port 114, the outside air discharge part 122 of the heat exchange element, the outside air supply part 121 of the heat exchange element, the second bypass part 151, and the exhaust port 112 are sequentially moved. You can.

Specifically, ventilation may be implemented by driving the first fan 141 in 'negative pressure' mode. That is, in the ventilation device 100, the internal air (indoor air) ventilation port 113, the ventilation area (R3), the internal air supply unit 123 of the heat exchange element 120, the internal air discharge unit 124, the exhaust area (R4), and the exhaust port. It can be provided outdoors after sequentially passing through (112) (PAT5a). PAT5a can correspond to the above-described PAT2.

Accordingly, only ventilation can be performed without supply air flowing into the room. Accordingly, the fluid in the room is reduced so that negative pressure in the room can be implemented or maintained.

Furthermore, during negative pressure, the negative pressure may be realized only by driving the first fan 141. This can be equally applied to other sound pressure modes below. The ventilation opening 113 and the air supply opening 114 may each have different or the same amount of fluid movement. Thereby, the above-mentioned sound pressure can be maintained. Additionally, as another example, the second fan 142 may be driven differently from the drive during air supply. For example, the second fan 142 may be rotated in a different direction than when air is supplied. That is, the second fan may be driven in a direction opposite to the rotation direction when external air is introduced into the room, and the second bypass unit may be open.

For all of these embodiments, the fluid flows through the supply port 114, the air supply region R2, the outside air discharge section 122 of the heat exchange element 120, the outside air supply section 121 of the heat exchange element 120, and the second bypass. It can move to section 151, exhaust area (R4), and exhaust port 112 (PAT5b).

As a result, indoor fluid (air) can be moved or discharged to the outdoors or to the exhaust port 112 through the ventilation port 113 and the supply port 114. Accordingly, the fluid in the room is reduced so that negative pressure in the room can be implemented or maintained. In this case, the indoor fluid moves outdoors through both the ventilation opening 113 and the air supply opening 114, making it possible to more efficiently and quickly create or maintain the room in a set negative pressure state. For example, the control unit uses data received from a ventilation device or a negative pressure sensor (pressure sensor, etc.) connected to the ventilation device to implement the user's desired or preset negative pressure state by using the first and second fans, the first and second fans described above. The operation of the bypass unit can be controlled.

Furthermore, through the ventilation device according to the embodiment, by using one ventilation device of the present invention in one room (hospital room), the amount of exhaust air required for negative pressure and the amount of air supply required for ventilation are adjusted to achieve purification, ventilation, and negative pressure without an additional positive pressure device. can be performed. In other words, the ventilation device alone can perform cleaning, ventilation, and negative pressure without a separate positive pressure device in the front room.

For example, one of the air supply units (the first sub air supply unit) can be connected to the hospital room, and the other one (the second sub air supply unit) can be connected to the anteroom. Furthermore, the ventilation device can adjust the air supply amount of the second sub air supply unit to be greater than the air supply amount of the first sub air supply unit. Additionally, for example, the amount of air supply may be adjusted by the difference in size between the first sub air supply unit and the second sub air supply unit. Accordingly, the hospital room may be in a negative pressure state. In other words, when the door to a hospital room is opened, air may flow in from the front room connected to the hospital room. Furthermore, the ventilation device can simultaneously perform ventilation. In other words, the ventilation device supply and exhaust can be performed simultaneously. As a result, clean air can be introduced into the room (anteroom) and hospital room. Also, by setting the sum of the air supply amount of the first sub-air supply part and the air supply amount of the second sub-air supply part of the ventilation device to be equal to the exhaust amount of the exhaust part, it is possible to maintain a negative pressure state in the hospital room.

Looking further at Figure 16, in the 'negative pressure' mode, the first bypass unit 131 of the ventilation device may be driven open (or open) or closed (or closed). 14 and 15, the first bypass unit 131 may be closed. However, in FIG. 16, the first bypass unit 131 may be open.

That is, when the ventilation device is in the negative pressure mode, fluid can further move through the ventilation port 113, the first bypass unit 131, the second bypass unit 151, and the exhaust port 112 in that order.

As described above, when the ventilation device operates in 'negative pressure' mode at each user's input or preset condition/time, the control unit operates the first bypass unit 131, the second bypass unit 151, and the second bypass unit 131. The control signal can be transmitted to the first fan 141, the second fan 142, etc.

Specifically, when the first bypass unit 131 is opened, indoor air flows into the ventilation port 113, the ventilation area (R3), the first bypass unit 131, the outside air area (R1), and the second bypass unit 151. ), can move to the exhaust area (R4) and exhaust port 112 (PAT5c).

FIG. 17 is a diagram of an internal structure explaining the flow of fluid during another operation mode in the ventilation device according to the embodiment, and FIG. 18 illustrates the flow of fluid during another operation mode in the ventilation device according to the embodiment. This is a side view of the internal structure.

Referring to FIGS. 17 and 18 , the ventilation device according to the embodiment may apply a 'negative pressure' mode (combined with exhaust) at the same time as ventilation/supply.

For example, in the ventilation device 100, the outside air is supplied to the outside device 111, the outside air area (R1), the outside air supply part 121 of the heat exchange element 120, the outside air discharge part 122, the air supply area (R2), and the air supply area (R2). It may be provided indoors through the apparatus 114 sequentially (PAT6b). And at the same time, in the ventilation device 100, there is an internal air (indoor air) vent 113, a ventilation area (R3), an internal air supply part 123, an internal air discharge part 124, an exhaust area (R4) and an exhaust port of the heat exchange element 120. It can be provided outdoors through (112) sequentially (PAT6b). At this time, the first bypass unit 131 may be in a closed state.

Furthermore, the amount of indoor air moving outdoors (PAT6a) may be less than the amount of outdoor air moving indoors (PAT6b). In other words, the amount of ventilation may be greater than the amount of air supply. Accordingly, the fluid in the room is reduced so that negative pressure in the room can be implemented or maintained. In other words, as the inflow and outflow of indoor and outdoor air occurs (implementation of air purification or ventilation), the negative pressure relative to the indoor negative pressure can be implemented or maintained.

Furthermore, when a ventilation device is placed inside a recess in a concrete layer located at the boundary between each floor in a building such as an apartment, 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 can be reduced. Accordingly, the ceiling height between the ceiling and the floor can be increased. Furthermore, the height of the band height may be reduced. Here, the semi-height may be the space or area between the ceiling and the upper floor or the floor of the upper floor. In other words, the ceiling height of the building can be increased or the ceiling height can be reduced by the ventilation device according to the embodiment. As a result, wastewater pipes, ceiling-type air conditioners, ventilation devices, etc. are installed in the semi-arch, so the height of the semi-arch is lowered due to the reduction in the height or thickness of the ventilation device, and the floor height of the building (the total height of the roof layer of the building from the first floor of the building) is lowered. You can. In particular, height reduction may be more effective for high-rise buildings. Furthermore, the load on the building decreases due to the reduction in half height and story height, and the rebar, wood materials, labor costs, process period, and amount of concrete used in the building can be reduced. In other words, the effect of reducing construction costs can be improved. Furthermore, by reducing the floor height, issues such as height restrictions can be easily overcome, and the amount of waste during demolition can also be effectively reduced.
