1 is a block diagram showing the configuration of a ventilation guide device according to an embodiment of the present invention.

Referring to Figure 1, the ventilation guide device 100 according to an embodiment of the present invention includes a structural data acquisition unit 110, a simulation data acquisition unit 120, a condition selection unit 130, and a simulation unit ( 140), a visualization unit 150, a ventilation condition calculation unit 160, a communication unit 170, and a storage unit 180 may be included.

The structural data acquisition unit 110 may acquire structural data of the building. For example, building structural data may be obtained from an external database containing structural information on the building where the user resides. If there is no data on the building structure in the external database, the user can set the building structure data arbitrarily, such as by directly writing it through an input unit (not shown). For example, structural data of a building can be obtained through user measurement using a 3D scanner, if necessary. At this time, when the 3D scanner is placed in the living room, kitchen, and each room inside the house and activated, it can automatically perform stereoscopic imaging and measure the building structure in 3D form.

The simulation data acquisition unit 120 may acquire simulation data for calculating the state of the building's internal air quality. For example, simulation data may include the amount of air leakage from a building, the amount of air from an exhaust device provided in the building, etc.

For example, among the simulation data, the amount of air leakage in a building may be a value acquired based on the amount of air leakage data according to the construction period of the building. In addition, the amount of air leakage in a building is obtained by measuring the amount of air leakage in parts that communicate with the outside, such as windows and entrances of the building, and may be a value obtained based on the wind direction and wind speed according to the location of the building. For example, the air volume of an exhaust device may include the air volume generated by a hood installed inside a building, a diffuser, and a bathroom vent.

In addition, the building's structural data and various simulation data previously stored in the storage unit 180 can be automatically updated each time they are newly acquired by the structural data acquisition unit 110 and the simulation data acquisition unit 120. .

The condition selection unit 130 may select at least one condition that affects the internal air quality of the building based on the user's input. At this time, conditions selectable by the condition selection unit 130 may include conditions related to time, weather, outside air quality, and indoor conditions.

For example, among selectable conditions, time may include a desired time of day, such as daytime, night, or dawn, and may also include seasons such as summer or winter. Additionally, the weather may include weather conditions such as clear, cloudy, rain, snow, wind direction, and wind speed, and external air quality may include the amount of pollutants such as fine dust concentration. Additionally, indoor situations may include various situations that can affect indoor air quality, such as cooking, studying, exercising, and sleeping.

The simulation unit 140 may simulate the state of the building's internal air quality using a simulation model that inputs the building's structural data, simulation data, and selected values of conditions selected by user input. In this case, the simulation unit 140 may perform a simulation using past simulation result data (for example, simulation result values stored in the storage unit 180).

For example, when the condition selected by the condition selection unit 130 is a cooking situation, the simulation unit 140 may simulate the state of the internal air quality of the building based on the amount of pollutants generated depending on the type of food being cooked. You can. Additionally, when the condition selected by the condition selection unit 130 is a study or sleeping situation, the simulation unit 140 may simulate the state of the air quality inside the building based on the amount of carbon dioxide generated during breathing. At this time, the simulation unit 140 may calculate the state of the building's internal air quality based on average carbon dioxide emissions according to age, the number of people living indoors at the time of simulation, etc.

The simulation unit 140 can predict changes in the state of the building's internal air quality according to the ventilation conditions calculated by the ventilation condition calculation unit 160 through simulation. That is, the simulation unit 140 performs ventilation based on the ventilation conditions calculated by the ventilation condition calculation unit 160, for example, the open/closed status of each window, the operating status and setting values of equipment such as the indoor clean ventilation device. You can simulate the change in air quality inside a building when

For example, if the level of pollutants outside the building (e.g., concentration of fine dust) is greater than or equal to a preset standard value and the condition selected by the condition selection unit 130 is a cooking situation, the simulation unit 140 determines the food being cooked. Based on the amount of pollutants generated depending on the type (e.g., mackerel, which produces a large amount of fine dust), if the hood is not used, the window of the building is open, if the hood is used, and the window is closed. In each situation, such as when using a hood, when using a clean ventilation device without using a hood, or when using a cooking-specific mode (or concentrated supply air) of a hood and a clean ventilation device together, the air quality inside the building can be checked. State changes can be predicted through simulation. Through this, when the air quality is poor due to the high concentration of fine dust outside, it is possible to easily visualize whether the user can remove the source of contamination in the most effective way when cooking indoors, which generates a lot of fine dust.

The visualization unit 150 may generate visual data about the internal air quality of the building based on the results of the simulation by the simulation unit 140. At this time, the visual data generated by the visualization unit 150 may be displayed through a display unit (not shown) or a user terminal.

The visualization unit 150 may generate visual data representing changes in the state of the building's internal air quality over time. At this time, the visualization unit 150 may generate visual data that displays the state of the building's internal air quality based on color changes. For example, visual data can be generated to display in red if indoor fine dust is very bad, and in blue if it is very good. For example, the visualization unit 150 may display changes in the state of a building's internal air quality over time in the form of a plurality of images or generate visual data to display them as a video.

Additionally, the visualization unit 150 may generate visual data that displays the level of pollution sources inside the building. For example, the visualization unit 150 may generate visual data to display specific values of pollutants such as fine dust, radon, and TVOC inside the building.

The visualization unit 150 may generate visual data that compares the state of the air quality inside the building when the clean ventilation device provided inside the building is not used and when the clean ventilation device is used. Therefore, the user can visually confirm the effect of the clean ventilation device provided indoors.

The ventilation condition calculation unit 160 may calculate ventilation conditions for improving the internal air quality of the building using a simulation model. In this case, the ventilation condition calculation unit 160 may perform simulation using past simulation result data (for example, simulation result values stored in the storage unit 180). Additionally, the ventilation condition calculation unit 160 may provide ventilation conditions through natural ventilation or a clean ventilation device depending on external conditions. In this way, the ventilation condition calculation unit 160 can provide a solution to the user after installing the clean ventilation device, such as whether natural ventilation is efficient in the current situation or which mode of the clean ventilation device is efficient.

For example, when the level of pollutants outside the building is less than a preset standard and the external temperature is within an appropriate range, the ventilation condition calculation unit 160 creates windows that can naturally ventilate the building's internal air quality to be within the normal range. You can select. Specifically, when the level of pollutants outside the building is less than a preset standard value, the ventilation condition calculation unit 160 may select a window that will most quickly bring the air quality inside the building into the normal range. In addition, when the level of pollutants outside the building is less than a preset standard value, the ventilation condition calculation unit 160 may select a window that ensures that the air quality inside the building is within a normal range within a preset time.

In addition, the ventilation condition calculation unit 160 ensures that the internal air quality of the building is within the normal range as quickly as possible when the external temperature is too high or low and natural ventilation is not appropriate even if the level of pollutants outside the building is below the preset standard value. Alternatively, the setting conditions of the clean ventilation device that ensure that the building's internal air quality falls within a normal range within a preset time can be calculated.

Therefore, when the air quality is good because the concentration of external fine dust is low, energy loss can be reduced by encouraging people to open windows, which can most effectively improve air quality, rather than using clean ventilation devices installed indoors.

The ventilation condition calculation unit 160 may calculate a set value of a clean ventilation device provided inside the building to ensure that the air quality inside the building is within a normal range. In this case, the ventilation condition calculation unit 160 may calculate the set value of the clean ventilation device so that the internal air quality of the building is within the normal range within a preset time. Through this, power can be used efficiently by providing settings that can most efficiently improve the building's internal air quality without the user having to change the mode of the clean ventilation device multiple times.

In this way, the ventilation condition calculation unit 160 calculates the devices for improving the internal air quality of the building (for example, a clean ventilation device), such as the location of the window to be opened among the windows provided indoors and the setting value of the clean ventilation device. Conditions for most efficiently removing indoor pollutants can be calculated.

The communication unit 170 may transmit information on the state of air quality inside the building obtained by the simulation unit 140 to the user's terminal. Therefore, the user can check the indoor air quality status in real time from outside through the terminal. In addition, the communication unit 170 receives data for calculating the internal air quality of the building, for example, the structure of the building described above, the amount of air leakage, external air quality data, and air volume data of the exhaust device, from an external server (not shown). can do.

In addition, the communication unit 170 opens and closes the windows of the building (for example, in the case of automatically controllable windows) with a set value according to the ventilation conditions calculated by the ventilation condition calculation unit 160, or clean ventilation provided inside the building. A signal that drives a device can be transmitted.

The storage unit 180 contains structural data of the building acquired by the structural data acquisition unit 110, simulation data acquired by the simulation data acquisition unit 120, and data regarding conditions selectable by the condition selection unit 130. Various data can be stored, etc. In addition, the storage unit 180 uses the ventilation guide device 100 of the present invention, such as state data of air quality inside the building simulated through the simulation unit 140 and ventilation condition data calculated through the ventilation condition calculation unit 160. Various simulated output data can be saved.

In this way, according to the ventilation guide device according to an embodiment of the present invention, it is possible to visually display how the internal air quality of a building changes for each situation through simulation and to indicate an effective air quality improvement plan to the user. Examples of simulation results for each situation are as follows.

<Case 1: General case>

go. When the concentration of fine dust outside is high (when the air quality is poor)

When there is a high concentration of fine dust outside, the building's internal air quality is simulated using the building's structural data, diffuser air volume measurements in each room if there is an exhaust device, external air quality data, and leakage data according to the building's construction period. can do. At this time, the ventilation guide device according to an embodiment of the present invention adjusts the indoor fine dust levels (e.g., PM 1.0, PM 2.5, PM 10) can be visualized and displayed (for example, if fine dust is very bad, it is red, and if it is very good, it is blue), and the value that changes over time can be visualized and displayed. Additionally, if necessary, levels of other pollutants such as radon and TVOC can also be displayed.

In this way, the ventilation guide device according to an embodiment of the present invention simulates the indoor air quality status and displays it based on the structure of the building so that the user can easily understand when there is a lot of fine dust, and improves indoor air quality through a clean ventilation device, etc. After performing this, you can even display changes in air quality over time.

me. When the concentration of fine dust outside is low (when the air quality is good)

If the concentration of fine dust outside is low, the building's internal air quality can be simulated using the building's structural data and external air quality data. In this case, the ventilation guide device visualizes changes in indoor air through a simulation program and determines which pollutants to most effectively remove pollutants (e.g., fine dust, radon, CO2, TVOC, etc.) when indoor air pollution increases. It can inform the user whether the location's windows should be opened. Additionally, when installing automatically controlled windows, it can notify you to open a small window at that location.

In this way, the ventilation guide device according to an embodiment of the present invention opens the most effective window according to the living environment in which the user lives without using a device such as a clean ventilation device when there is little external fine dust and the air quality is good, thereby polluting the indoor air. It can be visualized so that condensed air can be quickly removed. In addition, by guiding users to operate clean ventilation devices during summer and winter, energy loss can be minimized when operating air conditioners/heaters to save power.

<Case 2: When cooking indoors>

go. When the concentration of fine dust outside is high (when the air quality is poor)

When cooking indoors with a high concentration of external fine dust, structural data of the building, diffuser air volume in each room if there is an exhaust device in the building and hood air volume data installed in the building, external air quality data, and the construction period of the building. The internal air quality of a building can be simulated using leakage data. At this time, the ventilation guide device according to an embodiment of the present invention uses a simulation program to determine the amount of fine dust generated depending on the type of cooking when the hood is not used, when only the hood is used, and when the clean ventilation device and the hood are used simultaneously. For each situation, it is possible to visualize and display how fine dust levels change in the location of the cook, living room, etc.

Therefore, when the air quality is poor due to a lot of fine dust outside, when cooking indoors, which generates a lot of fine dust, the cook can clearly visualize and inform the cook how to remove fine dust in the most effective way.

me. When the concentration of fine dust outside is low (when the air quality is good)

When cooking indoors with a low concentration of external fine dust, structural data of the building, air volume from the diffuser in each room if there is an exhaust device and air volume measurement data from the hood installed in the building, air leakage volume data according to the construction period of the building and external air quality data can be used to simulate the building's internal air quality. At this time, the ventilation guide device uses a simulation program to determine the amount of fine dust generated depending on the type of cooking when opening the window at a specific location and using the hood, when not using the hood, and when only the hood is used without opening the window. When using a clean ventilation device and a hood at the same time, it is possible to visualize and display how fine dust levels change in the location of the cook, living room, etc.

In this way, according to the air quality simulation device of the present invention, when there is little fine dust outside and the air quality is good, a simulation program is used to determine the most effective method suitable for the residential environment in which the user lives when using or not using devices such as a clean ventilation device. It can be provided through. Through this, it is possible to visualize and display the contaminated air generated during cooking so that it can be quickly removed, and to minimize energy loss when operating the air conditioner/heater in summer and winter.

<Case 3: Studying or sleeping indoors>

go. When the concentration of fine dust outside is high (when the air quality is poor)

When the concentration of fine dust is high outside and the user is studying or sleeping, structural data of the building, diffuser air volume measurement data in each room if there is an exhaust device, external air quality data, and leakage data according to the construction period of the building, and The internal air quality of a building can be simulated using age-related carbon dioxide emissions data. At this time, the ventilation guide device uses a simulation program to visualize how the amount of carbon dioxide generated from breathing while studying or sleeping changes when the clean ventilation device is turned on (including the wind speed) and when it is not turned on. It can be displayed.

Therefore, the ventilation guide device according to an embodiment of the present invention can easily visualize and inform the user of the amount of carbon dioxide generated when studying or sleeping indoors when there is a lot of fine dust outside and the air quality is poor.

me. When the concentration of fine dust outside is low (when the air quality is good)

If the user is studying or sleeping when the concentration of fine dust outside is low, the building's internal air quality can be simulated using the building's internal structure data, external air quality data, and carbon dioxide emissions according to age. At this time, the ventilation guide device uses a simulation program to visualize the amount of carbon dioxide generated from breathing while studying or sleeping, how the amount of carbon dioxide can be effectively reduced by opening the window, and how it changes over time. It can be displayed.

In this way, according to the ventilation guide device of the present invention, when the concentration of fine dust outside is low and the air quality is good, the simulation program allows the user to open the most effective window according to the living environment in which the user lives without using devices such as a clean ventilation device. This can be visually shown to reduce carbon dioxide emissions.

However, situations that can be simulated through the ventilation guide device according to an embodiment of the present invention are not limited to those described above, and in addition, simulations can be performed on various situations that may affect indoor air quality.

As such, according to the ventilation guide device according to an embodiment of the present invention, the state of indoor air quality calculated through simulation based on the structure of the building and changes in air quality over time are visualized and displayed to the user, allowing the user to You can determine the air quality status more accurately and easily.

In addition, the state of indoor air quality can be calculated through simulation based on the structure of the building, and based on this, the state of indoor air quality can be provided to provide optimal ventilation conditions to remove indoor pollutants, allowing users to efficiently improve indoor air quality. there is.

In this way, the ventilation guide device according to an embodiment of the present invention can provide a solution and guide users using clean ventilation devices to effectively manage indoor air quality through simulation.

Figure 2 is a diagram explaining analyzing the structure of a building to visualize indoor air quality.

Referring to FIG. 2, the ventilation guide device according to an embodiment of the present invention simulates and visualizes the state of internal air quality by measuring the area, volume, plan configuration of the room, whether duct work can be installed, etc. Structural data of the building included can be acquired. At this time, structural data of the building can be acquired by the structural data acquisition unit 110 of FIG. 2. For example, structural data of a building may be received from an external server through the communication unit 170 or may be stored in advance in the storage unit 180.

Specifically, for a building that has already been completed, if there is data about the building structure in a database connected to the building, the corresponding data can be received through the communication unit 170, and the internal air quality of the building can be simulated using this. However, if there is no data on the building structure in the database, the three-dimensional structure of the building is directly measured using a 3D scanner, as shown in FIG. 2, and the building structure data acquired by the measurement is stored in the storage unit 180. It can be saved in .

On the other hand, in the case of a new building that has not been completed, the building structure is directly created through a drawing creation program such as CAD (Computer Aided Design) based on the design drawing of the building, as shown in Figure 2, and stored in the storage unit ( 180) can be saved in advance.

However, the method of acquiring structural data of a building from a ventilation guide device according to an embodiment of the present invention is not limited to FIG. 2, and various other methods may be used.

Figure 3 is a diagram illustrating visualization of indoor air quality through a ventilation guide device according to an embodiment of the present invention.

In Figure 3, the top right is a diagram showing the internal structure of the building, and the bottom right shows the concentration of indoor fine dust (μg/m ³ ) in color changes. Additionally, on the left side of Figure 3, changes in internal air quality are shown through color changes based on the structure of the building. In the example of Figure 3, as the concentration of indoor fine dust increases, it is displayed in red, and as it decreases, it is displayed in blue. In this way, users can easily check the fine dust concentration, or air quality, in each part of the room through a screen visualized based on the structure of the building.

Meanwhile, as shown in FIG. 3, various data for calculating the indoor air quality status can be received, for example, by receiving various status values from sensors installed indoors or external servers by an air monitor installed indoors, or by receiving weather or fine details from a web server. It can be obtained in various ways, such as receiving weather information such as dust. The data obtained in this way may include, for example, the above-described building structure data, air volume of the exhaust device, building air leakage amount, and external fine dust data, etc., and may be used as input values of the above-described simulation model.

As such, the ventilation guide device according to an embodiment of the present invention displays the internal air quality based on the structure of the building along with the levels of pollutants such as fine dust through techniques such as color changes, allowing users to easily view the building's condition at a glance. It is possible to determine the internal air quality status.

Figure 4 is a graph showing improvement of indoor air quality using a ventilation guide device according to an embodiment of the present invention.

Specifically, Figure 4 shows indoor fine dust in a situation where improvement is necessary due to indoor walking activities due to high fine dust indoors, natural ventilation is not appropriate due to a lot of fine dust outside, and it is desirable to operate the clean ventilation device in air purifying mode. This is simulation data representing dust concentration.

Referring to FIG. 4, when the initial concentration of indoor fine dust is 10 μg/m ³ while the outdoor fine dust concentration is very poor (75 μg/m ³ or more), the horizontal axis of the graph represents time (hours), and the vertical axis represents time (hours). represents the fine dust concentration of PM 2.5. In addition, in Figure 4, when the user walks indoors for 30 minutes at 7:00, 12:00, and 18:00, the clean ventilation device provided indoors is set to the air purification mode of 200 CMH at 7:00, 12:00, and 18:00, respectively. It shows the change in fine dust concentration at each location indoors after operation.

As shown in Figure 4, the concentration of fine dust in the living room and each room (main room, rooms 1 and 2) increased to 38μg/m ³ at 7:00, 12:00, and 18:00 when the user performed indoor walking activities. can be seen. This is because pollutants such as carbon dioxide are generated through walking activities. In this case, the ventilation guide device according to an embodiment of the present invention simulates the current internal air quality condition of the building, calculates ventilation conditions suitable for the current condition, and operates exhaust devices such as windows or clean ventilation devices to improve internal air quality. You can do it. Therefore, as can be seen in Figure 4, the fine dust concentration increases at 7:00, 12:00, and 18:00 when the user performs walking activities, and then gradually decreases again.

Figure 5 is a diagram illustrating the effect of improving indoor air quality through a ventilation guide device according to an embodiment of the present invention.

Specifically, Figure 5 shows a simulation of improving air quality using the air purification mode of a clean ventilation device rather than natural ventilation due to the high concentration of outdoor fine dust. In Figure 5, the upper right is a diagram showing the internal structure of the building, and the right shows the concentration of indoor fine dust (μg/m ³ ) as a color change. Additionally, on the left side of Figure 3, changes in internal air quality over time based on the structure of the building are shown through changes in color. In the example of Figure 5, as in the case of Figure 3, as the concentration of indoor fine dust increases, it is displayed in red, and as it decreases, it is displayed in blue. In addition, in the building structure diagram shown in the upper right corner of Figure 5, the part marked with a red arrow is the exhaust diffuser, where indoor air exits for filtering, and the part marked with a blue arrow is the supply air diffuser, where the air exiting the exhaust diffuser is discharged. It represents the part that is filtered and re-enters the room.

In FIG. 5, the initial indoor fine dust concentration was assumed to be 53 μg/m ³ , and after preventing further fine dust from being generated indoors, the clean ventilation device installed indoors was operated for 60 minutes. As can be seen in Figure 5, by operating the air purification mode of the clean ventilation device based on the results simulated through the ventilation guide device according to an embodiment of the present invention, 600 seconds (10 minutes) and 1200 seconds (20 minutes) ), 1800 seconds (30 minutes), and 3600 seconds (60 minutes), you can visually see that the internal air quality is gradually improving.

That is, through Figure 5, it can be seen that the air quality improves over time, focusing on the air supply portion of the air supply diffuser. Therefore, the ventilation guide device according to an embodiment of the present invention allows consumers (users) to visualize the air quality improvement effect over time when the clean ventilation device is operated.

Figure 6 is a graph showing improvement of indoor air quality using a ventilation guide device according to an embodiment of the present invention when a user is cooking.

Referring to FIG. 6, when the initial concentration of indoor fine dust is 10 μg/m3 while the outdoor fine dust concentration is very poor (75 μg/m3 or more), the horizontal axis of the graph represents time (hours), and the vertical axis represents PM. Indicates a fine dust concentration of 2.5. In addition, in Figure 6, when the user cooks bacon indoors for 10 minutes at 7:00 and 18:00, the clean ventilation device provided indoors is operated in the concentrated air supply mode of 200 CMH for 30 minutes at 7:00 and 18:00, respectively. Later, it shows the change in fine dust concentration at each location indoors.

In other words, when cooking indoors, the concentration of indoor fine dust becomes very high. In order to resolve this, it is desirable to activate the cooking mode of the clean ventilation device. At this time, the cooking mode of the clean ventilation device operates the hood and supplies concentrated air from the clean ventilation device to the kitchen (or, in some cases, supplies air to all rooms), thereby preventing fine dust generated during cooking from spreading to other spaces such as the living room. By directing the air supply toward the hood, it helps exhaust the hood and effectively and quickly reduces the concentration of fine dust.

As shown in Figure 6, it can be seen that the concentration of fine dust in the living room and each room (main room, rooms 1 and 2) rapidly increases to 190μg/m3 at 7:00 and 18:00 when the user is cooking indoors. . This is because contaminants such as fine dust are generated as bacon is cooked. Even in this case, the ventilation guide device according to an embodiment of the present invention simulates the current internal air quality state of the building, calculates ventilation conditions suitable for the current state, and operates the clean ventilation device in concentrated air supply mode to improve internal air quality. You can. Therefore, as can be seen in Figure 6, it can be seen that the concentration of fine dust rises rapidly at 7:00 and 18:00 when the user starts cooking, and then gradually decreases again.

Figure 7 is a diagram illustrating visualization of the indoor air condition through a ventilation guide device according to an embodiment of the present invention when a user is cooking.

Figure 7 is a diagram showing the concentrated air supply of a clean ventilation device. In order to prevent the spread of fine dust generated during cooking, the air supply is concentrated at the front of the hood. In this case, the flow rate is increased, showing a situation in which the hood contaminants are unable to escape toward the living room. there is. The upper right corner of Figure 7 shows the internal structure of the building, and the lower right corner shows the indoor air flow rate (m/s) as a color change. At this time, when the flow speed is fast, it is shown in red, and as the flow speed becomes slower, it is shown in blue. In addition, Figures 7 (a) and (b) show the side view and top view of the change in flow rate when the indoor clean ventilation device (concentrated air supply mode in Figure 6) and hood are operated based on the structure of the building through color change. Each road is indicated.

As shown in Figure 7, when a user is cooking, it can be seen that a supply air flow is formed through an exhaust device such as a clean ventilation device and a hood. In this way, the ventilation guide device according to an embodiment of the present invention displays not only the concentration of pollutants such as fine dust, but also the change in flow rate due to the exhaust device, etc., allowing the user to determine the state of the airflow.

Figure 8 is a flowchart showing an air quality simulation method according to an embodiment of the present invention.

Referring to FIG. 8, in the air quality simulation method according to an embodiment of the present invention, structural data of the building is first acquired (S110). In this case, the structure of the building can be obtained from the database inside the house where the user lives in the case of an apartment complex, and if there is no data on the building structure in the database inside the house, the building structure can be acquired through a 3D scanner as needed. The structure can be measured.

Then, simulation data to calculate the state of the building's internal air quality is acquired (S120). At this time, the simulation data may include the amount of air leakage in the building, the amount of air from the exhaust device provided in the building, etc. For example, among the simulation data, the amount of air leakage in a building may be a value acquired based on the amount of air leakage data according to the construction period of the building. In addition, the amount of air leakage in a building is obtained by measuring the amount of air leakage in parts that communicate with the outside, such as windows and entrances of the building, and may be a value obtained based on the wind direction and wind speed according to the location of the building. For example, the air volume of an exhaust device may include the volume of air generated by a hood installed inside a building, a diffuser, and a bathroom vent.

Next, at least one condition affecting the state of the building's internal air quality is selected based on the user's input (S130). At this time, conditions selectable in step S130 may include conditions regarding time, weather, outside air quality, and indoor conditions. For example, among selectable conditions, time may include a desired time of day, such as daytime, night, or dawn, and may also include seasons such as summer or winter. Additionally, the weather may include weather conditions such as clear, cloudy, rain, snow, wind direction, and wind speed, and external air quality may include the amount of pollutants such as fine dust concentration. Additionally, indoor situations may include various situations that can affect indoor air quality, such as cooking, studying, exercising, and sleeping.

Then, the internal air quality of the building is simulated using a simulation model that inputs the building's structural data, simulation data, and selected values of conditions selected by the user's input (S140).

For example, in step S140, when the condition selected in step S130 is a cooking situation, the state of the air quality inside the building can be simulated based on the amount of pollutants generated depending on the type of food being cooked. Additionally, when the selected condition is a study or sleeping situation, the state of the building's internal air quality can be simulated based on the amount of carbon dioxide generated during breathing.

Additionally, in step S140, changes in the state of the building's internal air quality according to ventilation conditions calculated through simulation can be predicted. In other words, it is possible to simulate changes in the building's internal air quality when ventilation is performed based on the ventilation conditions calculated in step S140, such as the open/closed status of each window, the operating status and settings of equipment such as indoor clean ventilation devices, etc. there is.

Next, visual data about the building's internal air quality is generated based on the simulation results (S150). At this time, the visual data generated in step S150 may be displayed through a display unit or a user terminal.

Additionally, in step S150, visual data indicating changes in the state of the building's internal air quality over time may be generated. At this time, visual data that displays the state of the building's internal air quality based on color changes can be generated. For example, in step S150, changes in the state of the building's internal air quality over time can be displayed in the form of a plurality of images or visual data can be generated to display it as a video.

Additionally, in step S150, visual data indicating the level of pollution sources inside the building can be generated. In this case, visual data can be generated to display specific values of pollutants such as fine dust, radon, and TVOC inside the building.

In step S150, visual data can be additionally generated to compare the state of the air quality inside the building when the clean ventilation device provided inside the building is not used and when the clean ventilation device is used. Therefore, the user can visually confirm the effect of the clean ventilation device provided indoors.

Meanwhile, although not shown in FIG. 8, the air quality simulation method according to an embodiment of the present invention may further include transmitting information on the state of air quality inside the building to the user's terminal. Therefore, the user can check the indoor air quality status in real time from outside through the terminal.

As such, according to the air quality simulation method according to an embodiment of the present invention, the state of indoor air quality calculated through simulation based on the structure of the building and changes in air quality over time are visualized and displayed to the user, allowing the user to You can determine the air quality status more accurately and easily.

Figure 9 is a flowchart showing an air quality simulation method according to another embodiment of the present invention.

Referring to FIG. 9, steps S210 to S240 are substantially the same as those of FIG. 8, so detailed description is omitted. Meanwhile, in step S250 of FIG. 9, ventilation conditions for improving the internal air quality of the building can be calculated using a simulation model. In this case, in step S250, if the level of pollutants outside the building is less than a preset standard value, a window that ensures that the air quality inside the building is within the normal range can be selected.

For example, if the level of pollutants outside the building is below a preset standard, windows can be selected that will bring the building's internal air quality back to the normal range as quickly as possible. In addition, when the level of pollutants outside the building is below a preset standard, windows can be selected to ensure that the air quality inside the building falls within the normal range within a preset time. Therefore, when the air quality is good because the concentration of external fine dust is low, energy loss can be reduced by encouraging people to open windows, which can most effectively improve air quality, rather than using clean ventilation devices installed indoors.

Additionally, in step S250, the set value of the clean ventilation device provided inside the building to ensure that the air quality inside the building is within the normal range can be calculated. In this case, the set value of the clean ventilation device that ensures that the building's internal air quality falls within the normal range within a preset time can be calculated. Through this, power can be used efficiently by providing settings that can most efficiently improve the building's internal air quality without the user having to change the mode of the clean ventilation device multiple times.

Meanwhile, although not shown in FIG. 9, the air quality simulation method according to another embodiment of the present invention opens or closes the windows of the building (for example, in the case of automatically controllable windows) with a set value according to the ventilation conditions calculated in step S250. It may further include transmitting a signal to drive a clean ventilation device provided inside the building.

As such, according to the air quality simulation method according to another embodiment of the present invention, the state of indoor air quality is calculated through simulation based on the structure of the building, and based on this, optimal ventilation conditions are provided to remove indoor pollutants. By doing so, users can efficiently improve indoor air quality.
