The measurement sensing unit 510 may be a flow velocity sensor or a pressure sensor that measures the flow velocity or pressure at the rear end of the filter member after the air has passed through the filter member.

When the ventilation device 100 is initially driven, the initial value storage unit 520 may set and store the flow rate or pressure measured by the measurement sensing unit 510 as the initial flow rate or initial pressure.

Here, the initial flow rate or initial pressure is the flow rate or pressure when the filter member is in a clean state in which the filter member is not contaminated at all. , when the filter member is replaced in the course of use, including the case when the ventilation device is first driven after replacement.

When the ventilation device is repeatedly driven after the initial driving of the ventilation device 100 , the reduction rate calculation unit 530 calculates the flow rate or pressure measured by the measurement sensing unit 510 each time the stored initial flow speed or initial pressure. can be compared to calculate the reduction rate.

As the driving time of the ventilation device 100 increases, the measured flow rate or pressure decreases as the pollution degree of the filter member increases, and the calculated reduction rate is gradually increased, for example, 10%, 20%, 30%, etc. this will be done

The contamination rate calculation unit 540 may calculate the contamination level of the filter member as a ratio value of contamination such as 10%, 20%, 30%, etc. according to the calculated reduction rate, and in this case, the contamination rate may be increased.

For example, if a proportional formula of pollution rate = reduction rate × 2 is stored as proportional data, in the pollution rate calculation unit 540, if the reduction rate is 5%, the pollution rate is 10%, if the reduction rate is 25%, the pollution rate is 50%, and the reduction rate is 50%. If it is 50%, the pollution rate is calculated as 100%.

The replacement determination unit 550 may generate a filter replacement signal by determining whether the contamination rate calculated by the contamination rate calculation unit 540 reaches a set replacement contamination rate.

The replacement determination unit 550 sets and stores the replacement contamination rate (eg, 100%) of the filter member through a pre-experiment, and when the calculated contamination rate reaches the stored replacement contamination rate, a filter replacement signal may be generated.

The pollution information output unit 560 may output the pollution rate information calculated by the pollution rate calculation unit 540 and the filter replacement signal generated by the replacement determination unit 550 and provide it to the user terminal 300 .

The contamination rate information and filter replacement signal of the filter member provided by the contamination information output unit 560 are received by the user terminal 300 through the wireless communication unit 310, and the received contamination rate information and filter replacement information are displayed on the display unit ( 360) and aurally displayed through the sound output unit 370, the user can clearly and quickly recognize the filter contamination information and replacement information.

In addition, in each room ventilation control system of the present invention, the user can easily and quickly check detailed contamination information on the filter member and information on the replacement time through the user terminal 300, so that the ventilation efficiency according to the contamination of the filter member is reduced. It is possible to more conveniently perform maintenance on the filter member while preventing deterioration.

That is, as the ventilation device 100 is used for a long time, the pollution level of the filter member increases, and if it is not replaced at an appropriate time, various problems such as a decrease in ventilation efficiency may occur. 500) outputs the contamination information and replacement signal of the filter member, and the contamination information and replacement signal are displayed through the display unit 360 and the sound output unit 370 of the user terminal 300 carried by the user, so the user can easily check how much contamination of the filter member is progressing, and also easily recognize the replacement time of the filter member, so that maintenance such as proper replacement of the filter member can be conveniently performed.
