In the air circulation system according to the present invention, when the ventilation unit 1 is operated as described above, the exhaust unit 200 is also operated together.

1 shows a state in which both the ventilation unit 1 and the exhaust unit 200 are in operation.

Referring to FIG. 1, the controller 400 operates the air supply fan 21 and the exhaust fan 22 during the operation of the ventilation unit 1. Therefore, the air supply is made through the ventilation unit 1, and the exhaust is made through the exhaust unit 200.

Hereinafter, the clean ventilation mode among the ventilation modes will be described as an example. In addition to the clean ventilation mode, the method of operating both the ventilation unit 1 and the exhaust unit 200 in the natural ventilation mode or the indoor clean mode may be applied in the same manner.

When the air supply fan 21 is operated, the outside air introduced through the outside air inlet 13a is purified by the filter 40 while passing through the heat exchanger 30.

In the heat exchanger 30, heat exchange between the outside air and the indoor air is performed.

The air heat-exchanged with indoor air while passing through the heat exchanger 30 is discharged to the air supply duct 110 through the indoor air supply 11a.

The air exiting the air supply duct 110 is distributed to the first to fourth chambers R1 to R4 through the multi-branch unit 100 to supply air.

At this time, the control unit 400 may supply only at least some of the rooms according to the ventilation conditions of the first to fourth rooms (R1 to R4), or may control the air supply rate differently for each of the rooms.

For example, the ventilation condition includes at least one of carbon dioxide concentration of indoor air in each room, presence or absence of occupants in each room, water vapor, smell, and moisture in each room. However, the present invention is not limited thereto, and ventilation of each room may be individually controlled using other conditions.

On the other hand, the indoor air in the room R is exhausted only through the exhaust chamber R5.

The controller 400 operates the exhaust fan 22 and controls the opening / closing member 230 to open the opening 201.

When the opening 201 is opened and the exhaust fan 22 is operated, air in the first to fourth chambers R1 to R4 is sucked into the exhaust chamber R5 through the opening 201.

The air sucked into the exhaust chamber R5 passes through the exhaust duct 210 and enters the indoor exhaust port 12a of the ventilation unit 1.

The indoor air introduced into the ventilation unit 1 through the indoor exhaust port 12a is heat-exchanged with the outside air while passing through the heat exchanger 30, and then is discharged to the outside through the outdoor exhaust port 14a.

As described above, in the present invention, the air supply to the room is made up of the plurality of first to fourth rooms R1 to R4 through the ventilation unit 1, respectively, and the exhaust from the room is only in the exhaust chamber R5. Is done.

Therefore, since it is not necessary to connect the exhaust duct for each of the plurality of chambers, the exhaust duct equipment can be minimized. By minimizing the exhaust duct installation, installation and maintenance costs can be reduced.

In addition, the amount of exhaust gas is increased in the exhaust chamber R5 in which odors and moisture are higher than those of other chambers, so that the exhaust chamber R5 such as a toilet or a bathroom can be more comfortably maintained.

On the other hand, Figure 2 is a view schematically showing a state in which only the exhaust in the exhaust chamber when the ventilation unit is stopped in the air circulation system according to an embodiment of the present invention.

Referring to FIG. 2, a state in which the exhaust gas is generated when the ventilation unit 1 is stopped is described.

If it is determined that the ventilation of the room is not necessary according to the values measured by the indoor pollution degree measuring unit 71 and the indoor carbon dioxide concentration measuring unit 73, the control unit 400 stops the operation of the ventilation unit 1. Stop it.

When the operation of the ventilation unit 1 is stopped and the air supply fan 21 and the exhaust fan 22 are stopped, the controller 400 determines whether the exhaust chamber R5 is used in real time.

Since the exhaust chamber R5 is a toilet or a bathroom, an odor or humidity is increased when in use, and thus the exhaust chamber R5 needs to be exhausted regardless of ventilation of other rooms in the room.

Whether or not the exhaust chamber R5 is used may be determined depending on whether or not power is applied to the lights of the exhaust chamber R5, or may be determined depending on whether or not the occupant of the exhaust chamber R5 is occupied. Do.

When the exhaust chamber R5 is determined to be in use by the exhaust chamber use detecting unit 310, the controller 400 operates the exhaust fan 22 in a stopped state. The opening and closing member 230 controls to open the opening 201.

When the opening 201 is opened and the exhaust fan 22 is operated, air in the first to fourth chambers R1 to R4 is sucked into the exhaust chamber R5 through the opening 201.

The air sucked into the exhaust chamber R5 passes through the exhaust duct 210 and enters the indoor exhaust port 12a of the ventilation unit 1.

The indoor air introduced into the ventilation unit 1 through the indoor exhaust port 12a is heat-exchanged with the outside air while passing through the heat exchanger 30, and then is discharged to the outside through the outdoor exhaust port 14a.

Thereafter, when it is determined that the use of the exhaust chamber R5 is terminated, the controller 400 operates the exhaust fan 22 for a preset time period from the time when the use of the exhaust chamber R5 is terminated. Thereafter, when the set time elapses, the operation of the exhaust fan 22 is stopped. Therefore, indoor air of the said exhaust chamber R5 can be exhausted sufficiently. However, the present invention is not limited thereto, and the operation of the exhaust fan 22 may be stopped when the use of the exhaust chamber R5 ends.

As described above, since the exhaust fan 22 can be operated when the exhaust chamber R5 is used even when ventilation of the room is not necessary, the exhaust chamber R5 corresponding to the toilet or bathroom can be comfortably maintained. Can be.

In the above embodiment, the opening and closing member 230 opens the opening 201 while the exhaust chamber R5 is in use. However, the present disclosure is not limited thereto, but the exhaust chamber R5 is used. The opening and closing member 230 may shield the opening 201 to protect the privacy of the user.

That is, when it is determined that the exhaust chamber R5 is in use, the controller 400 controls the opening / closing member 230 to automatically shield the opening 201. At this time, the exhaust fan 22 can be operated.

Subsequently, when it is determined that the use of the exhaust chamber R5 is finished, the controller 400 controls the opening / closing member 230 to open the opening 201 automatically, The operation of the exhaust fan 22 can be maintained from the end of use until the preset time elapses.

Therefore, even if the opening 201 is closed during the use of the exhaust chamber R5, the opening 201 is opened and the exhaust fan 22 is operated for a predetermined time after the use of the exhaust chamber R5. The exhaust chamber R5 can be sufficiently ventilated.

On the other hand, Figure 3 is a view schematically showing a state in which the exhaust from the exhaust chamber and the emergency duct when an emergency situation occurs in the air circulation system according to an embodiment of the present invention.

Referring to FIG. 3, when it is determined that the emergency situation is determined from the information detected by the emergency situation detecting unit 320, the control unit 400 operates the exhaust fan 22, and the opening / closing member 230 opens the opening. 201 is controlled to open.

In addition, the controller 400 controls the emergency valve 242 to open the emergency duct 240.

Here, the emergency situation may include a case where at least one of the temperature and humidity of the room measured by the indoor temperature and humidity measuring unit 75 as well as the occurrence of a fire exceeds a preset limit value.

When both the opening 201 and the emergency duct 240 are opened, some of the air in the first to fourth chambers R1 to R4 are sucked into the exhaust chamber R5 through the opening 201. The remaining air may be exhausted through the emergency duct 240.

Accordingly, by exhausting only through the exhaust chamber R5 at normal times and not in an emergency situation, the emergency duct 240 may be opened and exhausted only when an emergency situation occurs, so that an emergency situation may be minimized even if the exhaust duct facility is minimized.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
