1 is a conceptual diagram for explaining an indoor air purification system of a multi-storey apartment house according to an embodiment, and FIG. 2 is a block diagram for explaining the system shown in FIG. 1 .

Referring to FIGS. 1 and 2 for an indoor air purification system of a multi-storey apartment house according to an embodiment, an air purifier 2 may be provided inside and outside to purify the indoor air of the multi-storey apartment house 1 have.

In this embodiment, the multi-storey apartment house 1 is an individual household, and the interior is located in the first living space 10 on the first floor and on the first living space 10 by a movable structure such as the first floor and stairs. It may have a multi-layered structure including the second living space 12 of two floors, but is not limited thereto. For example, the multi-storey apartment house 1 may further include a three-story living space or an attic space located above the second living space.

At this time, the first living space 10 and the second living space 12 may include at least one window, but is not limited thereto.

The air purifier 2 may include an air purifier 20 , a first indoor sensor unit 22 , a second indoor sensor unit 24 , and an outdoor sensor unit 26 .

The air purifier 20 receives the indoor air information obtained through the first indoor sensor unit 22 and the second indoor sensor unit 24 based on the outdoor air information received through the outdoor sensor unit 26 in real time. It is possible to purify the air of the first living space 10 and the second living space 12 in response to the acquired and preset reference air information.

At this time, the first indoor sensor unit 22 is disposed in the first living space 10 to obtain first indoor air information including the indoor oxygen concentration and indoor carbon dioxide concentration of the first living space 10 in real time. have.

In addition, the second indoor sensor unit 24 is disposed in the second living space 12 to obtain second indoor air information including the indoor oxygen concentration and the indoor carbon dioxide concentration of the second living space 12 in real time. have.

In addition, the outdoor sensor unit 26 is disposed outdoors of the multi-storey apartment building 1 to acquire outdoor air information including outdoor oxygen concentration and outdoor carbon dioxide concentration in real time.

Specifically, when the outdoor air information acquired in real time is lower than the reference air information, that is, when the outdoor air pollution degree is lower than the standard air pollution degree, the air purifier 20 compares the standard air information with the indoor air information to compare the outdoor air Indoor air can be purified through inflow or indoor air circulation.

For example, when the first indoor air pollution degree of the first living space 10 is lower than the reference air pollution degree, the air purifier 20 determines that the first indoor carbon dioxide concentration is lower than the standard carbon dioxide concentration, and the first indoor oxygen concentration is When it is higher than the reference oxygen concentration, the first indoor air circulation information is generated based on the reference air pollution level, and the internal air circulation speed and circulation time of the first living space 10 are adjusted in response to the first indoor air pollution level to adjust the circulation time for the first life. It is possible to purify the air by circulating the internal air of the space (10).

In addition, when the first indoor air pollution degree of the first living space 10 is higher than the reference air pollution degree, the air purifier 20 determines that the first indoor carbon dioxide concentration is higher than the reference carbon dioxide concentration, and the first indoor oxygen concentration is the reference oxygen When it is lower than the concentration, the first outdoor air inflow information is generated based on the standard air pollution level, and the outdoor air is introduced into the first living space 10 by adjusting the outdoor air inflow amount and inflow time in response to the first indoor air pollution level. It can purify the air. That is, the air purifier 20 can purify the air of the first living space 10 by introducing outdoor air by calculating the relative pollution degree and insufficient oxygen concentration of the first living space 10 . In this case, the relative pollution degree may be a value representing the outdoor air pollution degree compared to the first indoor air pollution degree of the first living space 10 , but is not limited thereto.

In addition, when the second indoor air pollution degree of the second living space 12 is lower than the reference air pollution degree, the air purifier 20 determines that the second indoor carbon dioxide concentration is lower than the standard carbon dioxide concentration, and the second indoor oxygen concentration is the reference oxygen When it is higher than the concentration, the second indoor air circulation information is generated based on the reference air pollution level, and the internal air circulation speed and circulation time of the second living space 12 are adjusted in response to the second indoor air pollution level to adjust the second living space ( 12) It is possible to purify the air by circulating the internal air.

And, when the second indoor air pollution degree of the second living space 12 is higher than the standard air pollution degree, the air purifier 20 determines that the second indoor carbon dioxide concentration is higher than the standard carbon dioxide concentration, and the second indoor oxygen concentration is the reference oxygen When it is lower than the concentration, the second outdoor air inflow information is generated based on the standard air pollution level, and the outdoor air is introduced into the second living space 12 by adjusting the outdoor air inflow amount and inflow time in response to the second indoor air pollution level. It can purify the air. That is, the air purifier 20 can purify the air of the second living space 12 by introducing outdoor air by calculating the relative pollution degree and insufficient oxygen concentration of the second living space 12 . In this case, the relative pollution degree may be a value representing the outdoor air pollution degree compared to the second indoor air pollution degree of the second living space 12 , but is not limited thereto.

Here, the air purifier 20 may purify the air of the first living space 10 and then purify the air of the second living space 12 . In general, in the case of the multi-storey apartment building 1, the air in the first living space 10 flows into the second living space 12 relatively due to the temperature difference between the first living space 10 and the second living space 12. As it moves, the degree of pollution of the air in the second living space 12 may be affected by the air in the first living space 10 .

Therefore, after purifying the air in the first living space 10 and purifying the air in the second living space 12 , the air in the second living space 12 is more rapidly purged to form the first living space 10 and Since the second living space 12 is uniformly purified, it is possible to more efficiently purify the indoor air.

However, unlike this, the air of the first living space 10 and the second living space 12 is simultaneously purged or the air of the first living space 10 is purified after purifying the air of the second living space 12 . can do it

On the other hand, if it is determined that the indoor air pollution degree is higher than the standard pollution degree even though the outdoor air pollution degree is lower than the standard air pollution degree, the air purifier 20 may introduce outdoor air to purify the indoor air through indoor air circulation.

For example, if the reference oxygen concentration is set to 50% based on 100%, if the indoor oxygen concentration is less than 30%, it is judged that it may cause difficulty breathing, headache, fainting, etc. Regardless of the level of outdoor air pollution, outdoor air can be introduced to purify indoor air through indoor air circulation.

Depending on the embodiment, whether to ventilate may be determined according to the selection of the resident of the multi-storey apartment (1).

The operation of the indoor air purification system of a multi-storey apartment house according to an embodiment of the present invention having such a structure is as follows.

3 is a view for explaining a method for purifying indoor air of a multi-storey apartment house according to an embodiment.

First, as shown in FIG. 3 , indoor air information can be set using the air purifier 2 ( S100 ).

For example, the indoor air information may be set as reference air information of the multi-storey apartment building 1 . At this time, the reference air information may include, but is not limited to, an average reference oxygen concentration and a reference carbon dioxide concentration suitable for a resident to live in an indoor space such as a two-story apartment building (1).

According to the embodiment, the indoor air information may be set according to the selection of the resident of the multi-storey apartment building 1 .

Next, the air purifier 2 may obtain indoor air information and outdoor air information of the multi-storey apartment house 1 in real time and compare it with reference air information to calculate the indoor air pollution level and the outdoor air pollution level (S110) .

For example, the air purifier 2 includes the first indoor oxygen concentration and indoor carbon dioxide concentration of the first living space 10 from the first indoor sensor unit 22 disposed in the first living space 10 . Second indoor air including indoor oxygen concentration and indoor carbon dioxide concentration in the second living space 12 from the second indoor sensor unit 24 arranged in the second living space 12 by acquiring indoor air information in real time Information is acquired in real time, and outdoor air information including outdoor oxygen concentration and outdoor carbon dioxide concentration can be acquired in real time from the outdoor sensor unit 26 disposed outdoors of the multi-storey apartment building 1 .

Next, the air purifier (2) compares the outdoor air pollution degree with the standard air pollution degree (S120). You can decide whether to ventilate or not.

Specifically, when it is determined that the indoor air pollution degree is higher than the standard air pollution degree because the indoor carbon dioxide concentration is higher than the standard carbon dioxide concentration and the indoor oxygen concentration is lower than the standard oxygen concentration (S130), the air purifier 2 is based on the standard air pollution degree It is possible to calculate the outdoor air inflow information corresponding to the indoor air pollution degree (S140).

For example, since the indoor air pollution degree is high because the indoor oxygen concentration is low and the indoor carbon dioxide concentration is high, the air purifier 2 responds to the relative pollution degree comparing the indoor air pollution degree with the outdoor air pollution degree of the outdoor air flowing into the room. The flow rate and flow rate can be adjusted.

In this case, the relative pollution degree is a value representing the outdoor air pollution degree compared to the indoor air pollution degree, and it can be determined that the greater the value, the greater the pollution degree.

Next, the air purifier 2 uses the calculated outdoor air inflow information to adjust the inflow amount and inflow time of the outdoor air in response to the indoor air pollution level, and introduces the outdoor air into the multi-story apartment building 1 can be purified (S150).

That is, the air purifier 2 calculates the insufficient oxygen concentration inside the multi-storey apartment building 1 and introduces outdoor air corresponding to the oxygen concentration to purify the air of the multi-storey apartment house 1 .

On the other hand, when it is determined that the indoor air pollution level is lower than the standard air pollution degree because the indoor carbon dioxide concentration is lower than the standard carbon dioxide concentration and the indoor oxygen concentration is higher than the standard oxygen concentration (S160), the air purifier 2 is based on the standard air pollution degree It is possible to calculate the indoor air circulation information corresponding to the indoor air pollution degree (S170).

For example, since the indoor air pollution degree is low because the indoor oxygen concentration is high and the indoor carbon dioxide concentration is low, the air purifier 2 adjusts the internal air circulation speed and circulation time in response to the indoor air pollution degree to adjust the internal air circulation speed and circulation time in the multi-storey apartment house (1) It is possible to purify the air by circulating the inside air.

Meanwhile, the air purifier 2 compares the outdoor air pollution degree with the standard air pollution degree (S120), and if the outdoor air pollution degree is higher than the standard air pollution degree, compares the indoor air pollution degree with the standard air pollution degree to respond to the indoor air pollution degree. It is possible to purify the air by circulating the internal air of the multi-storey apartment building (1) by adjusting the air circulation speed and circulation time.

4 is a view for explaining a method for purifying indoor air in first and second living spaces of a multi-storey apartment house according to an embodiment.

First, as shown in FIG. 4 , the air purifier 2 acquires the first indoor air information and outdoor air information of the first living space 10 of the multi-storey apartment building 1 in real time to obtain reference air information and By comparison, the first indoor air pollution degree and the outdoor air pollution degree may be calculated (S200).

For example, the air purifier 2 includes the first indoor oxygen concentration and indoor carbon dioxide concentration of the first living space 10 from the first indoor sensor unit 22 disposed in the first living space 10 . Indoor air information can be acquired in real time, and outdoor air information including outdoor oxygen concentration and outdoor carbon dioxide concentration can be acquired in real time from the outdoor sensor unit 26 disposed outdoors of the multi-storey apartment building 1 .

Next, when the outdoor air pollution degree is lower than the standard air pollution degree, the first indoor carbon dioxide concentration is higher than the standard carbon dioxide concentration, and the first indoor oxygen concentration is lower than the reference oxygen concentration, so that the first indoor air pollution degree is judged to be higher than the standard air pollution degree In case (S202), the air purifier 2 may calculate the first outdoor air inflow information corresponding to the first indoor air pollution level based on the reference air pollution level (S204).

For example, since the first indoor air pollution degree is high because the first indoor oxygen concentration is low and the first indoor carbon dioxide concentration is high, the air purifier 2 compares the first indoor air pollution degree with the outdoor air pollution degree. In response, the inflow amount and inflow speed of the outdoor air flowing into the first living space 10 may be adjusted.

In this case, the first relative pollution degree is a value representing the outdoor air pollution degree compared to the first indoor air pollution degree, and it may be determined that the greater the value, the greater the pollution degree.

Next, the air purifier 2 adjusts the inflow amount and inflow time of the outdoor air in response to the first indoor air pollution level using the calculated first outdoor air inflow information, and then moves the outdoor air into the interior of the first living space 10 . The air may be purified by introducing air (S206).

That is, the air purifier 2 may calculate the insufficient oxygen concentration inside the first living space 10 and introduce outdoor air corresponding to the oxygen concentration to purify the air in the first living space 10 .

Next, the air purifier 2 acquires the second indoor air information and outdoor air information of the second living space 12 of the multi-storey apartment building 1 in real time, and compares it with the reference air information to the first indoor air pollution degree , it is possible to calculate the second indoor air pollution degree and outdoor air pollution degree (S206).

For example, the air purifier 2 includes a second indoor oxygen concentration and an indoor carbon dioxide concentration of the second living space 12 from the second indoor sensor unit 24 disposed in the second living space 12 . Indoor air information can be acquired in real time, and outdoor air information including outdoor oxygen concentration and outdoor carbon dioxide concentration can be acquired in real time from the outdoor sensor unit 26 disposed outdoors of the multi-storey apartment building 1 .

Next, when the outdoor air pollution degree is lower than the standard air pollution degree, the second indoor carbon dioxide concentration is higher than the standard carbon dioxide concentration, and the second indoor oxygen concentration is lower than the reference oxygen concentration, so that the second indoor air pollution degree is determined to be higher than the standard air pollution degree In case (S210), the air purifier 2 may calculate the second outdoor air inflow information corresponding to the second indoor air pollution level based on the reference air pollution level (S212).

For example, since the second indoor oxygen concentration is low and the second indoor carbon dioxide concentration is high, the second indoor air pollution degree is high. In response, the inflow amount and inflow speed of the outdoor air flowing into the second living space 12 may be adjusted.

In this case, the second relative pollution degree is a value representing the outdoor air pollution degree compared to the second indoor air pollution degree, and it may be determined that the greater the value, the greater the pollution degree.

Next, the air purifier 2 adjusts the inflow amount and inflow time of the outdoor air in response to the second indoor air pollution level using the calculated second outdoor air inflow information, and then moves the outdoor air to the inside of the second living space 12 . Air may be purified by introducing air (S214).

That is, the air purifier 2 calculates the insufficient oxygen concentration inside the second living space 12 and introduces outdoor air corresponding to the oxygen concentration to purify the air in the second living space 12 .

On the other hand, when it is determined that the first indoor carbon dioxide concentration is lower than the reference carbon dioxide concentration and the first indoor oxygen concentration is higher than the reference oxygen concentration, so that the first indoor air pollution degree is lower than the standard air pollution degree (S216), the air purifier (2) may calculate the first indoor air circulation information corresponding to the first indoor air pollution degree based on the reference air pollution degree (S218).

For example, since the first indoor air pollution degree is low because the first indoor oxygen concentration is high and the indoor carbon dioxide concentration is low, the air purifier 2 circulates the internal air of the first living space 10 in response to the first relative pollution degree. By controlling the speed and the circulation time, the internal air of the first living space 10 can be circulated to purify the air.

In addition, when it is determined that the second indoor carbon dioxide concentration is lower than the reference carbon dioxide concentration, and the second indoor oxygen concentration is higher than the reference oxygen concentration, so that the second indoor air pollution degree is lower than the standard air pollution degree (S220), the air purifier 2 is Second indoor air circulation information corresponding to the second indoor air pollution level may be calculated based on the reference air pollution level (S222).

For example, since the second indoor air pollution degree is low because the second indoor oxygen concentration is high and the indoor carbon dioxide concentration is low, the air purifier 2 circulates the internal air of the second living space 12 in response to the second relative pollution degree. By controlling the speed and the circulation time, the internal air of the second living space 12 can be circulated to purify the air.

5 is a view for explaining a method for purifying indoor air in first and second living spaces of a multi-storey apartment house according to another embodiment.

First, as shown in FIG. 5 , the air purifier 2 provides the first indoor air information of the first living space 10 of the multi-storey apartment 1 and the second of the second living space 12 in real time. The indoor air information and the outdoor air information may be obtained and compared with the reference air information to calculate the first and second relative pollution degrees (S300).

Specifically, the air purifier 2 includes the first indoor oxygen concentration and indoor carbon dioxide concentration of the first living space 10 from the first indoor sensor unit 22 disposed in the first living space 10 . Second indoor air information including indoor oxygen concentration and indoor carbon dioxide concentration of the second living space 12 from the second indoor sensor unit 24 disposed in the second living space 12, acquiring air information in real time can be obtained in real time, and outdoor air information including outdoor oxygen concentration and outdoor carbon dioxide concentration can be obtained in real time from the outdoor sensor unit 26 disposed outdoors of the multi-storey apartment building 1 .

Next, the air purifier 2 may calculate a first indoor air pollution degree, a second indoor air pollution degree, and an outdoor air pollution degree by using the obtained first indoor air information, second indoor air information, and outdoor air information.

Next, the air purifier 2 compares the first indoor air pollution degree with the outdoor air pollution degree, calculates a first relative pollution degree indicating the outdoor air pollution degree compared to the first indoor air pollution degree, and calculates the outdoor air pollution degree compared to the second indoor air pollution degree The indicated second relative pollution degree can be calculated.

Next, when the calculated first relative pollution degree is greater than the second relative pollution degree (S310), the air purifier 2 may determine whether to ventilate the first living space 10 (S320).

That is, in the air purifier 2, when the first relative pollution degree is greater than the second relative pollution degree, the first indoor air pollution degree of the first living space 10 is higher than the second indoor air pollution degree of the second living space 12. Since it is higher, the first indoor oxygen concentration and the first indoor carbon dioxide concentration of the first living space 10 are compared with the reference oxygen concentration and the reference carbon dioxide concentration, and the first corresponding to the first indoor air pollution degree is based on the reference air pollution degree. The air in the first living space 10 may be purified by calculating the outdoor air inflow information or the first indoor air circulation information.

Next, after purifying the air in the first living space 10 , the air purifier 2 may determine whether to ventilate the second living space 12 ( S330 ).

That is, the air purifier 2 compares the second indoor oxygen concentration and the second indoor carbon dioxide concentration of the second living space 12 with the reference oxygen concentration and the reference carbon dioxide concentration, and the second indoor air pollution degree based on the standard air pollution degree. The air in the second living space 12 may be purified by calculating second outdoor air inflow information or second indoor air circulation information corresponding to .

Meanwhile, when the calculated first relative pollution degree is smaller than the second relative pollution degree (S340), the air purifier 2 may determine whether to ventilate the second living space 12 (S350).

That is, when the first relative pollution degree is smaller than the second relative pollution degree, the second indoor air pollution degree of the second living space 12 is higher than the first indoor air pollution degree of the first living space 10 in the air purifier 2 . Since it is higher, the second indoor oxygen concentration and the second indoor carbon dioxide concentration of the second living space 12 are compared with the reference oxygen concentration and the reference carbon dioxide concentration, and the second corresponding to the second indoor air pollution degree is based on the reference air pollution degree.
