Description

Air quality management device and method
Technical Field
Embodiments disclosed herein relate to an air quality management apparatus and method.
Background
Recently, as air quality deteriorates due to fine dust and the like, people wearing a mask on the outside are increasing, and attention to improvement of indoor air quality is increasing, and it is becoming essential to provide an air cleaner in homes, offices and the like. In particular, in the case of an air cleaner manufactured at present, a user can grasp an approximate state of indoor air quality in a manner of lighting differently or providing a numerical value of a pollution source such as fine dust according to the state of indoor air quality.
However, such an air cleaner can provide only an approximate indoor air quality state, and cannot comprehensively provide air quality states for indoor locations such as a living room, a bedroom, a bathroom, and a kitchen. In the case where a relative area is large, such as a home or an office living in a family unit, the state of air quality may change depending on time and location, but at present, there is no appropriate method for grasping the state of air quality based on such an indoor structure. In addition, the conventional air purifier can only provide the current air quality state, but has a disadvantage that how the indoor air quality is changed cannot be confirmed according to the conditions and conditions required by the user.
In addition, a user generally improves the indoor air quality by opening a window or operating the air purifier according to the state of the indoor air quality displayed in the air purifier. However, there is a problem in that power is wasted when all windows are opened for ventilation or the air cleaner is operated excessively stronger than the current indoor air quality state, and there is a problem in that the indoor air cleaning effect is rather reduced when the windows are opened and the air cleaner is operated.

Fig. 1 is a block diagram showing a structure of an air quality management apparatus according to an embodiment disclosed in the present specification.
Referring to fig. 1, an air quality management apparatus 100 according to an embodiment disclosed herein may include an information acquisition part 110, a control part 120, and a sensor part 130.
The information acquisition part 110 may acquire structural information and weather information of a building. For example, the structural information of the building may include the number of windows provided in the building, the positions of the windows, the direction of the building, and the like. For example, meteorological information may include information about wind direction and wind speed outside a building. Further, the information acquisition part 110 may acquire information about a pollution source outside the building.
The information acquisition unit 110 may acquire the structural information of the building from a database provided inside or outside the building in which the user resides. If the structural information of the building does not exist in the database, the user may directly generate the structural information of the building through an input device (e.g., a desktop, a tablet PC, a user terminal, etc.) to acquire the structural information of the building. For example, the structure information of a building can be acquired by a user performing measurement by a 3D scanner as necessary. At this time, when the 3D scanner is operated after being placed in a living room, a kitchen, and each room inside a house, stereoscopic imaging can be automatically performed to perform measurement in a 3D format. This is illustrated in fig. 2.
Further, the information acquisition section 110 may acquire weather information from an external server. For example, the external server may include a weather bureau server or the like. At this time, the information acquisition part 110 may acquire weather information from an external server through a communication device.
The control part 120 may control the air quality management operation of the building based on the structural information and the weather information of the building. At this time, the control part 120 may control the air quality management operation of the building by controlling the opening and closing of the window provided in the building. For example, the control part 120 may automatically open or close the window based on information about the position of the building, the position and number of the window, and information about the wind direction and wind speed around the building.
The control section 120 may control an air quality management operation of the building based on the air quality outside the building. For example, when the value of the pollution source outside the building is smaller than the reference value, the control unit 120 may open a window of the building so that the air quality inside the building is within a normal range. At this time, when the value of the pollution source outside the building is less than the reference value, the control part 120 may open the window that makes the air quality inside the building within the normal range fastest. In addition, when the value of the pollution source outside the building is less than the reference value, the control part 120 may open a window that makes the air quality inside the building within a normal range for a set time. Further, the control unit 120 may drive the air cleaning device installed inside the building when the value of the pollution source outside the building is equal to or greater than the reference value.
Further, the control part 120 may determine whether to open and close a window provided in the building based on the air leakage amount information of the building. For example, the air leakage information of the building may include an average air leakage calculated according to the construction period of the building. Further, the air leakage amount information of the building may include information obtained by measuring air leakage amounts of windows and doorways provided in the building. The control unit 120 may determine whether to open or close a window provided in the building based on the air volume of the exhaust device provided in the building. For example, the air volume of the exhaust device may include air volume passing through a hood (hood) provided inside a building, a diffuser (diffuser), a vent of a bathroom, and the like.
Further, the control part 120 may determine whether to open and close a window provided in the building based on the outside temperature and the inside temperature of the building. For example, the control part 120 may determine whether to open and close a window provided in a building within a range in which a difference between an outside temperature and an inside temperature of the building is less than a reference temperature difference.
The sensor part 130 may detect an air quality state inside the building. For example, the sensor part 130 may be disposed inside a building to detect the concentration of pollutants generated inside the building.
Meanwhile, although not shown in fig. 1, the air quality management device 100 according to an embodiment disclosed in the present specification may further include a simulation part. In this case, the simulation unit may simulate the state of the internal air quality of the building by using a simulation model that has as input the structural information of the building, the air leakage amount of the building, the air volume of the exhaust device provided in the building, and other information, and the selection value of the condition selected by the input of the user. At this time, the simulation section may perform simulation using result data of previous simulation (e.g., previously stored simulation result value).
For example, when the condition selected by the user is a cooking condition, the simulation part may simulate the state of the internal air quality of the building based on the amount of the pollution source generated according to the kind of food cooked. Further, when the condition selected by the user is a learning condition or a sleep condition, the simulation part may simulate the state of the interior air quality of the building based on the amount of carbon dioxide generated while breathing. In this case, the simulation unit may calculate the state of the internal air quality of the building based on the average carbon dioxide emission amount according to the age, the number of people living in the room at the time of simulation, and the like.
The simulation part may predict a state change of the interior air quality of the building after the air quality management operation of the building is performed by the control part 120 through simulation. That is, the simulation unit may simulate an air quality control operation of the building, and for example, change in the internal air quality of the building when ventilation is performed based on the open/close state of each window, the start and set state of equipment such as an indoor air purification ventilation device, and the like.
For example, when the value of the pollution source (for example, the concentration of fine dust) outside the building is equal to or greater than a predetermined reference value and the condition selected by the user is the cooking state, the simulation unit may predict the state change of the internal air quality of the building by simulation based on the amount of the pollution source generated according to the type of food to be cooked (for example, mackerel which generates a large amount of fine dust), for various cases such as when the hood is not used, when the hood is used while opening the window of the building, when the hood is used while closing the window, when the clean ventilation apparatus is used without using the hood, and when the cooking special mode (or intensive air blowing) in which the hood and the clean ventilation apparatus are used simultaneously. Thus, when the air quality is poor due to the high concentration of the external fine dust, it can be easily visualized whether the user can remove the pollution source by the most effective method in cooking in which much dust is generated indoors.
Furthermore, although not shown in fig. 1, the air quality management device 100 according to an embodiment disclosed herein may further include a visualization portion. At this time, the visualization part may generate visualization data on the interior air quality of the building based on the simulation result of the simulation part. At this time, the visualized data generated by the visualizing part may be displayed by a display or a user terminal.
The visualization portion may generate visualization data representing a change in state of the interior air quality of the building over time. At this time, the visualization part may generate visualization data that displays the state of the interior air quality of the building based on the color change. For example, the visualized data may be generated so that when the amount of indoor dust is very large, red is displayed, and when the amount of indoor dust is very small, blue is displayed. For example, the visualization section may generate the visualization data in such a manner that a change in state of the interior air quality of the building over time is displayed in the form of a plurality of images or displayed in the form of a video.
The visualization unit may generate visualization data indicating a numerical value of the pollution source inside the building. For example, the visualization unit may generate the visualization data so as to display specific numerical values of pollution sources such as fine dust, radon, TVOC, and the like in the building together.
The visualization part may generate visualization data for comparing the state of the interior air quality of the building in a case where the purification ventilation device provided inside the building is not used and in a case where the purification ventilation device is used. Therefore, the user can visually confirm the effect of the purification ventilation apparatus provided indoors.
As described above, the air quality management apparatus 100 according to an embodiment disclosed herein may provide an optimal ventilation condition for effectively removing an indoor pollution source based on the structure and weather information of a building, thereby effectively improving the indoor air quality state.
Fig. 2 is a diagram for explaining a method of acquiring structural information of a building.
Referring to fig. 2, the information acquisition part 110 of the air quality management apparatus 100 according to an embodiment disclosed in the present specification may acquire structural information of a building including the position and number of windows provided in the building, the area, volume, planar structure of the interior of the building, the installation possibility of plumbing equipment (duct work), and the like. For example, the structural information of the building may be received from an external server or stored in advance in the air quality management apparatus 100.
Specifically, for a finished building, the information acquisition part 110 acquires information about the structure of the building when the information exists in a database connected to the building, and the control part 120 controls the air quality management operation of the building using the information. However, when the structure information of the building does not exist in the database, as shown in fig. 2, the three-dimensional structure of the building may be directly measured by the 3D scanner, and the structure information of the building acquired by the measurement may be stored.
In contrast, in the case of an unfinished new building, as shown in fig. 2, a user may directly create a building structure by a drawing program such as Computer Aided Design (CAD) based on a Design drawing of the building and store the building structure in the corresponding air quality management apparatus 100 in advance.
However, the method of acquiring the structural information of the building from the air quality management apparatus 100 according to an embodiment disclosed in the present specification is not limited to the method illustrated in fig. 2, and various methods other than the method may be used.
Fig. 3 is a diagram exemplarily illustrating a state of air quality in a room visualized by an air quality management apparatus of an embodiment disclosed in the present specification.
In FIG. 3, the upper right end is a diagram showing the internal structure of a building, and the lower right end is a diagram showing the concentration of fine dust in a room (μ g/m) with a color change 3 ) Is shown in (a). Further, the left side of fig. 3 shows the change in the interior air quality by a color change based on the structure of the building. In the example shown in fig. 3, the higher the concentration of the indoor fine dust is, the red color is displayed, and the lower the concentration of the indoor fine dust is, the blue color is displayed. Therefore, the user can easily confirm the fine dust concentration of each part in the room, that is, what state of the air quality is, on the visual screen based on the structure of the building.
On the other hand, various data for calculating the indoor air quality state as shown in fig. 3 can be acquired by various means such as measurement by the sensor unit 130 of fig. 1 (for example, an air monitor installed in a room) or reception of weather information such as a wind direction and a wind speed from an external server. The data thus acquired may include, for example, the above-described structural information of the building, the wind direction, the wind speed, the air leakage amount of the building, the air volume of the exhaust device, the external fine dust data, and the like, and may be used as input values of the simulation model of the simulation section.
As described above, in the air quality management apparatus 100 according to an embodiment of the present invention, the state of the interior air quality is displayed by a technique such as color change based on the value of the pollution source such as fine dust and the structure of the building, so that the user can easily grasp the interior air quality state of the building at a glance.
Fig. 4 is a diagram exemplarily illustrating an air quality management action of an air quality management apparatus according to an embodiment disclosed in the present specification.
Referring to fig. 4, windows W1 to W4 are provided in a living room and each room of a building in which the air quality management apparatus 100 according to an embodiment disclosed in the present specification is installed. In this case, the windows W1 to W4 may be windows that can be automatically opened and closed by the control unit 120 of the air quality control apparatus 100.
For example, as shown in fig. 4, when the wind outside the building is west wind, the information acquisition part 110 of the air quality management apparatus 100 according to an embodiment disclosed in this specification may acquire the structural information of the building of fig. 4 and information on the wind direction and the wind speed. Also, the control part 120 may control the windows W1, W2, and W3 to be opened and the window W4 to be closed based on the structural information of the building and the meteorological information on the wind direction and the wind speed.
On the other hand, although not shown in fig. 4, when the outside air quality deviates from the normal range (for example, when the concentration of fine dust is high), the air quality management apparatus 100 according to an embodiment disclosed in this specification may operate the air cleaning apparatus provided indoors while closing the windows W1 to W4.
As described above, the air quality management apparatus 100 according to an embodiment disclosed in this specification can effectively discharge indoor pollutants by associating the structural information of the building with information on the wind direction and the wind speed outside the building.
Fig. 5 is a flow chart illustrating an air quality management method according to an embodiment of the present disclosure.
Referring to fig. 5, in an air quality management method according to an embodiment disclosed in this specification, first, structural information and weather information of a building may be acquired (S110). For example, the structural information of the building may include the number of windows provided in the building, the positions of the windows, the direction of the building, and the like. For example, the meteorological information may include information relating to wind direction and wind speed outside a building. Further, in step S110, information about a pollution source outside the building may be acquired.
For example, in step S110, the structural information of the building may be acquired from a database provided inside or outside the building in which the user lives. If the structural information of the building does not exist in the database, the user may directly generate the structural information of the building through an input device (e.g., a desktop, a tablet PC, a user terminal, etc.) to acquire the structural information of the building. For example, the structure information of a building can be acquired by a user performing measurement by a 3D scanner as necessary. At this time, when the 3D scanner is operated after being placed in a living room, a kitchen, and each room inside a house, stereoscopic imaging can be automatically performed to perform measurement in a 3D format. Further, in step S110, weather information may be acquired from an external server. For example, the external server may include a weather bureau server.
And, the air quality management operation of the building may be controlled based on the structural information and weather information of the building (S120). At this time, in step S120, the air quality management operation of the building may be controlled by controlling the opening and closing of the window provided in the building. For example, in step S120, the window may be automatically opened or closed based on information about the position of the building, the position and number of windows, and information about the wind direction and wind speed around the building.
Further, in step S120, an air quality management operation of the building may be controlled based on the air quality outside the building. For example, when the value of the pollution source outside the building is smaller than the reference value, the window of the building may be opened so that the air quality inside the building is within a normal range. At this time, when the value of the pollution source outside the building is less than the reference value, a window that makes the air quality inside the building within the normal range fastest may be opened in step S120. In addition, in step S120, when the value of the pollution source outside the building is less than the reference value, a window may be opened such that the air quality inside the building is within a normal range for a set time. In step S120, when the value of the pollution source outside the building is equal to or greater than the reference value, the air cleaning device installed inside the building may be driven.
Further, in step S120, whether to open and close a window provided in the building may be determined based on information related to air leakage of the building. For example, the air leakage information of the building may include an average air leakage calculated from the construction period of the building. The air leakage amount information of the building may include information obtained by measuring air leakage amounts of windows and doors provided in the building. In step S120, whether to open or close a window provided in the building may be determined based on the air volume of the exhaust device provided in the building. For example, the air volume of the exhaust device may include air volume passing through a hood (hood) provided inside a building, a diffuser (diffuser), a vent of a bathroom, and the like.
Further, in step S120, whether to open and close a window provided in the building may be determined based on the outside temperature and the inside temperature of the building. For example, whether to open and close a window provided in a building may be determined in a range in which a difference between an outside temperature and an inside temperature of the building is less than a reference temperature difference.
As described above, in the air quality management method of an embodiment disclosed in this specification, it is possible to provide an optimal ventilation condition for effectively removing an indoor pollution source based on the structure and weather information of a building, thereby effectively improving the indoor air quality state.
