Lack of oxygen concentration (%) = Reference oxygen concentration (%) - Indoor oxygen concentration (%) ------(1)

Relative pollution (%) = Indoor pollutant concentration (%) - Outdoor pollutant concentration (%) ----(2)

For example, as shown in FIG. 4 , the external air introduced into the outdoor purifier 10 is firstly purified through the front filter unit 12 , is secondarily purified through the washing unit 141 , and a moisture agent It is purified in the third order through the rejection 16, in the fourth order through the rear filter 180, in the fifth order through the first clean filter 222, and flows into the room to increase the indoor oxygen concentration of the indoor air, Indoor air is purified through the second clean filter 232 and flows into the room, thereby reducing the indoor pollutant concentration in the indoor air. At this time, the washing unit 141 increases the supply amount of washing water due to the high inflow and high velocity of external air, so the injection amount of the washing water sprayed from the water injection nozzle 142 increases, and in response to the injection amount of the washing water, the washing tank ( 1410) and the rotation speed and rotation time of the rotor blade 1412 may be increased.

On the other hand, when the air volume control unit 40 is provided instead of the indoor air purifier 20, as the insufficient oxygen concentration and the relative pollution degree calculated by Equations (1) and (2) increase, the air volume is increased and discharged into the room. You can adjust the air volume.

For example, external air introduced into the outdoor purifier 10 is first purified through the front filter unit 12 , is secondarily purified through the washing unit 141 , and thirdly through the water removal unit 16 . It is purified and purified through the rear filter 180 in the fourth order, so that it can be quickly introduced into the room by the air volume control unit 40 . Accordingly, the indoor oxygen concentration of the indoor air may be increased, and the indoor pollutant concentration may be decreased due to the increase in the indoor oxygen concentration.

Next, after ventilation is completed, in the second calculation step, the indoor oxygen concentration of the indoor air measured by the outdoor sensor 101 and the indoor sensor 201 satisfies the reference oxygen concentration, and the indoor pollutant concentration exceeds the outdoor pollutant concentration. In this case, it is determined that only the degree of contamination of the indoor air is severe, so that purification is determined to stop the operation of the first indoor cleaning unit 220 , and only the second indoor cleaning unit 230 may be operated.

At this time, when only the second indoor cleaning unit 230 is operated, the operation of the cleaning unit 141 is stopped and washing water is not sprayed. By supplying wind to the rejection 16 , the front filter 120 and the discharge filter 162 may be dried.

According to the embodiment, when only the second indoor cleaning unit 230 is operated, the operation of the washing unit 141 is stopped and washing water is not sprayed, so that the first indoor cleaning unit 220 rotates in the reverse direction to rotate the rear filter unit. The rear filter 180 and the discharge filter 162 can be dried by supplying wind to the 18 and the water removal unit 16 .

Finally, when the indoor oxygen concentration measured in real time is greater than the reference oxygen concentration and the indoor pollutant concentration is less than the reference pollutant concentration, the operation of the outdoor purifier 10 and the indoor air purifier 20 is terminated, and pollutants in the ventilation process Indoor air purification can be completed by washing and drying the front filter 120, the rear filter 180, and the discharge filter 162 provided in the outdoor purifier 10 contaminated by the .
