When the indoor air of the main flow manufacturing facility 10 flows into the top of the main body through the conveyance path unit 200 connected to the upper side, The carbon dioxide absorbing liquid is injected toward the room air so that the carbon dioxide absorbing liquid injected in the course of the transportation is reacted with the carbon dioxide so that the carbon dioxide contained in the room air can be absorbed and removed, When carbon dioxide is absorbed in the injected carbon dioxide absorbing liquid, the carbon dioxide absorbing liquid in which the carbon dioxide is absorbed can be discharged.

The desorption treatment unit 500 is connected to the carbon dioxide removing unit 400 so as to allow the carbon dioxide absorbing liquid absorbed by the carbon dioxide to be introduced and to heat the absorbed carbon dioxide absorbing liquid so that the carbon dioxide is removed from the carbon dioxide absorbing liquid.

Here, the carbon dioxide absorbing liquid absorbed by carbon dioxide is heated by the desorption processing unit 500, and the reverse reaction is generated, so that the carbon dioxide can be desorbed from the carbon dioxide absorbing liquid.

When the carbon dioxide absorption liquid is absorbed by the carbon dioxide absorbing liquid, the controller 600 discharges the carbon dioxide absorbing liquid absorbed by the carbon dioxide from the carbon dioxide removing unit 400 to be transferred to the desorption unit 500, When the carbon dioxide absorption liquid flows into the desorption processing unit 500, the introduced carbon dioxide absorption liquid is heated so that the carbon dioxide is released from the carbon dioxide absorption liquid, and the carbon dioxide absorption liquid from which the carbon dioxide has been removed is transferred to the storage unit 300 so as to be reused .

The control unit 600 periodically discharges a predetermined amount of indoor air to the outside according to a temperature difference between the indoor air and the outdoor air periodically according to a predetermined schedule and allows the outdoor air of the discharged amount to flow into the room .

Specifically, the control unit 600 senses the concentration of carbon dioxide contained in the indoor air or senses the indoor air and the outdoor air temperature according to each schedule individually set by the sensing unit 100, When a predetermined amount of indoor air is discharged to the outside of the room according to the temperature difference between the air, outdoor air is discharged into the room, outdoor air is introduced into the room, and the concentration of carbon dioxide The concentration of the carbon dioxide contained in the room air can be detected so that the increase in the concentration of the carbon dioxide contained in the room air due to the inflow of the outside air can be minimized.
