Description

Air quality management system and method {SYSTEM AND METHOD FOR MANAGEMENT OF AIR QUALITY}

The following description is to provide an air quality management system and method that can differentially manage the air quality of the underground space.

As the industry develops, the environment becomes polluted. As the quality of life gets higher, the desire to improve it is getting bigger. However, the methodology to improve the scientific and systematic air quality is not enough yet.

For example, the indoor air quality that most people live in, for example, because the indoor air is simply ventilated only through manual or automatic opening and closing of the window through a conventional window, If the window is completely closed and sealed for security at night, it is impossible to ventilate or remove various harmful substances generated in the room, and various pollutants remain in the room, causing various problems.

Of course, some conventional air purifiers have been used as a method for improving indoor air quality, but there is a natural limitation in improving indoor air quality due to its function. In addition, since there is no measurement sensor to measure the value, it is difficult for the in-patients to check the amount of pollutants in the numerical value, which prevents efficient air quality improvement management. In addition, the improvement of the partial air quality depending on the sense, such as environmental improvement is not made in connection with other control or cleanliness. In particular, when the air purifier is molded for a long time, the amount of ozone (25%) emitted along with anion (about 75%) continues to increase, resulting in the inhaled organic compounds being overpowered.

However, due to the development of the industry and the improvement of the cultural level, the interest in health has been increasing recently due to the quality of life. Moreover, health is the most important and important element in human life. It is a fact that can not be denied. However, in our living space, many pollutants emitted from vehicles and industrial facilities, harmful substances generated from petroleum, building materials made of chemical-related materials, furniture, and electronics are threatening human health , The seriousness of which is increasing.

In particular, humans live in a limited indoor space of about 80% or more of the 24 hours a day, and continue to generate polluted air in the process, and the pollutant concentration in the room is inevitably increased by the generated polluted air. . At this time, if the concentration of pollution in the room is not properly adjusted or improved, humans have to drink unconsciously polluted air in their lives, and they live without harming their health.

There are about 250 species of substances that contaminate indoor air, including very small ones. Among them, in terms of housing, nitrogen dioxide generated from asbestos, including various volatile organic compounds (VOCs) such as formaldehyde (HCHO), radon, toluene, benzene, and acetone, which are carcinogenic substances generated from various interior building materials, etc. There is this. In addition, in human activities, carbon dioxide (CO2), dust, tobacco smoke, foot odors and microbial substances in various household products that are produced during the ignition of the gas used in cooking in the kitchen or the human breathing process ( Escherichia coli, Pseudomonas aeruginosa, 0-157, Salmonella) and volatile organic contaminants, other odors, noise, radiation and the like. It is well known that these various harmful substances cause various adverse effects on the human body, such as skin allergies, respiratory diseases or headaches.

Here, the pollutants generated from various building materials may be naturally extinguished to less than the allowable limit in the indoor pollution degree in about 1 to 5 years. Even in this case, the improvement of air quality until the concentration is lower than the standard concentration (1000 ppm or less based on CO2) proposed by the Public Health Control Act and the Building Act is a problem. In addition, various harmful substances such as carbon dioxide generated in human activities can not be eliminated. These are indispensable at the ecological and environmental level.

Therefore, it is necessary to improve the indoor air quality so that the indoor air quality is lowered to the allowable level or less even when the occupant is present or the window is closed when the appropriate criterion value is set above the allowable reference value It will be very important. This is because carbon dioxide generated from human activities is not designed to allow natural circulation of indoor air in our housing structure, so if natural circulation of harmful air is not achieved, the occupant will eventually breathe more carbon dioxide than the proper amount of oxygen. Inhale. In severe cases, problems arise that cause shortness of breath or serious impairments in brain movement.

However, the domestic housing construction industry has not been able to find a way to improve air quality in particular in relation to housing, and in recent years, national interest in the environment is increasing. As the “Indoor Air Quality Management Act” was enacted from 2004.06, it expanded to multi-use facilities such as underground stations, underground shopping malls, passenger terminals, libraries, and general hospitals, and newly built apartment houses. Strong measures such as public announcements are made to manage indoor air quality and improve the living environment.

However, the reality is that it does not keep up with human needs, and in the case of various products having functions of sterilization, deodorization, and air cleaning, which are conventionally used to improve various air quality, the air quality sensed by the sensor is merely detected by the sensor. It is not checked and managed. Above all, the indoor air quality cannot be directly seen and felt by the occupants, which makes it impossible to efficiently manage the indoor air quality.

In order to propose such a comprehensive environmental improvement method, it is urgent to develop a methodology for comprehensive improvement work starting from the index of sensor value or evaluation value.

On the other hand, the background art described above is possessed or acquired by the inventors in the process of deriving the present invention, and may not necessarily be a known technology disclosed to the public before the application of the present invention.

Hereinafter, the air quality management system 100 according to the embodiments will be described with reference to FIGS. 1 to 3. For reference, FIG. 1 is a schematic view of the air quality management system 100 according to an embodiment, and FIG. 2 illustrates some divided regions R1, R2, R3, and R4 in the air quality management system 100 according to an embodiment. It is a schematic diagram shown. 3 is a block diagram of an air quality management system 100 according to an embodiment.

Referring to the drawings, the air quality management system 10 includes a plurality of measurement units 110 for measuring air quality in the target space 10, and first to third information for storing information about the target space 10. It comprises a control unit 120 for controlling the operation of the providing unit (131, 132, 133) and the air conditioning system (11).

The measuring unit 110 is a target space 10 divided and partitioned into a plurality of divided regions R1, R2,..., Rn, and in the following description of the divided regions, reference numerals are denoted as 'R'. It is provided in, and it is provided in each division area R in at least 1 position or more, and measures air quality.

Here, the term "air quality" refers to a numerical value depending on the presence or concentration of contaminants in various types of air including fine dust and the like in a space to be measured.

The measuring unit 110 includes various sensors for measuring the presence or concentration of various pollutants. For example, indoor air contains various volatile organic compounds (VOCs) such as formaldehyde (HCHO), radon, toluene, benzene, and acetone, which are carcinogenic substances generated from various indoor building materials. CO2, dust, tobacco smoke, odors and other microbial substances in various household products (e.g. Escherichia coli, Pseudomonas aeruginosa, 0) from pollutants or the ignition of gases used to cook food in the kitchen or the human breathing process. -157, Salmonella) and volatile organic pollutants, and other pollutants such as odor, noise and radiation.

The measuring unit 110 may be a sensor for measuring various air pollutants. For example, the measuring unit 110 may include a temperature sensor, a humidity sensor, a radon (Rn) sensor, a floating dust sensor, a formaldehyde (HCHO) sensor, a total organic volatile compound (TVOC) sensor, a nitrogen dioxide (NO2) sensor, and carbon monoxide. It may include at least one or more of (CO) sensor, ozone (O3) sensor. However, this is only an example, and in addition to the measuring unit 110, various sensors capable of measuring various pollutants in the air such as carbon dioxide, methane, and odor may be applied.

Here, the measuring unit 110 may integrally measure a plurality of pollution or air quality in one sensor. Alternatively, the measuring unit 110 may be configured by integrating a plurality of sensors measuring different pollution or air quality into one. In this way, the measurement unit 110 may be provided with one sensor / integrated sensor in one or a plurality of positions. Alternatively, the measuring unit 110 may be provided with a plurality of sensors at each location for measuring different pollution or air quality. In this way, the measurement unit 110 may be provided with a plurality of sensors in each of a plurality of positions.

The target space 10 includes, for example, an underground mall. Here, the target space 10 is located in the basement, and includes a complex space composed of different purpose spaces such as restaurants, stores, passageways, and the like. Since the target space 10 is located in the basement, air is difficult to be polluted, and air is easily polluted, and the exchange of polluted air is not easy. In addition, the target space 10 includes a space for generating a large amount of air pollutants, such as a restaurant, and the amount of air pollutants generated varies depending on the location. In addition, the amount and air quality of the air pollutant inside the target space 10 may vary depending on external factors such as weather, time and seasons, and flow population, as well as internal factors.

Thus, in the present embodiment, the air quality management system 100 divides the target space 10 into a plurality of divided regions R, and since the air quality is different for each divided region R, the air quality is managed differently. In addition, the air quality management system 100 not only uses the result measured in the target space 10 but also manages the air quality by reflecting both internal and external factors of the target space 10. To this end, the air quality management system 100 stores factors that may affect the air quality of the target space 10 in the first to third information providing units 131, 132, and 133, and the first to third information. The air quality in the target space 10 is differentially managed by controlling the operation of the air conditioning system 11 by using the information stored in the providing units 131, 132, and 133.

The target space 10 is set to a plurality of divided regions R in consideration of characteristics of the internal space. For example, the target space 10 may set the divided region R by dividing and dividing the inside into a predetermined size. However, this is merely an example, and the target space 10 may be divided and partitioned into anomalous size to set the partition area R. FIG. For example, the divided area R sets the size of the divided area R to a small location where contaminants are generated, such as a restaurant, and increases the size of the divided area R to a location where less contaminants occur. Can be set. In addition, the division area R can also be set according to the position of the doorway through which the target space 10 communicates with the outside.

The space information on the target space 10 set as described above is stored in the first information providing unit 131. The spatial information includes the number of partitions R dividing the target space 10, the size and location of each partition R, and the type of each partition R (for example, a restaurant, an office space, a lounge, etc.). Information about the size of the doorway, and information about the size, location and number of the doorways, and information about the space where the doorway is connected (for example, whether the door is connected to the outside or connected to another space). In addition, the spatial information may include various information including spatial characteristics of the target space 10 and the partition area R. FIG.

The air conditioning system 11 which circulates air is provided in the target space 10. The air conditioning system 11 includes an intake port 111, an exhaust port 112, and the like. The air quality in the target space 10 is affected by the position of the intake port 111, the position and distance of the exhaust port 112, and the number thereof. Accordingly, the air quality management system 100 stores the position information of the air conditioning system 11 regarding the positions and distances of the intake and exhaust ports in the second information providing unit 132. However, this is only an example, and the second information providing unit 132 may store various information related to the air conditioning system 11 that may affect the air quality of the target space 10. Here, although only the intake port 111 and the exhaust port 112 are illustrated in the embodiment, the air conditioning system 11 includes various devices such as an air conditioner, a ventilation device, an air curtain, a heat exchanger, an air conditioner filter, and a booster fan. And the location information will include all the location information for the various components of the air conditioning system 11 that can affect the air quality of the target space (10).

The air quality of the target space 10 is influenced not only by internal factors but also by weather factors such as external weather and fine dust concentration, as well as external factors such as time, season, and floating population. Accordingly, the air quality management system 100 stores external factor information including external weather, fine dust concentration, time, season, and flow population in the third information providing unit 133.

Here, the third information provider 133 may include external factor information that directly measures the outdoor air quality of the target space 10 or data provided by an external organization. For example, outdoor air quality may be directly measured through a plurality of sensors installed outside or outside of the target space 10, and the measurement result may be stored in the third information providing unit 133. Alternatively, the third information providing unit may store and use various air pollution related data provided by the National Air Pollution Information Management System (NAMIS), Air Korea, the Korea Meteorological Agency, and local governments. Here, the National Air Pollution Information Management System (NAMIS) is an institution that collects and manages air pollution data such as sulfur dioxide, carbon monoxide, nitrogen dioxide, ozone, and fine dust at measuring stations located nationwide. May use infrastructure related to air pollution measurement networks measured and provided by the national air pollution information management system. In addition, the third information providing unit 133 expresses the measurement data of the five air environmental reference substances measured in the urban air monitoring network, roadside air monitoring network, national background monitoring network, suburban air monitoring network installed in the city / county in various forms. You can use the data of Air Korea to provide the people in real time. In addition, the third information providing unit 133 may also use data such as yellow dust alarms operated by the Korea Meteorological Agency and ozone alarms operated by local governments.

In addition, the third information providing unit 133 may store various external factors that may affect the air quality of the target space 10.

The controller 120 weights the result measured by the measurement unit 110 using the information stored in the first to third information providing units 131, 132, and 133, classifies the class, and classifies the class. According to this, the air quality of the divided region R is differentiated and managed. In addition, since the information stored in the first to third information providing units 131, 132, and 133 is also an index indicating that the air quality and the environment inside and outside the divided region R are changed, the controller 120 may be used. May automatically operate the air conditioning system 11 according to the information stored in the first to third information providing units 131, 132, and 133 to manage air quality of each divided area R. FIG.

Meanwhile, the exemplary embodiment exemplifies the first to third information providing units 131, 132, and 133 including spatial information, location information, and external factor information. This is merely an example. Therefore, more factors may be considered, and these factors may be stored in other information providing units other than the first to third information providing units 131, 132, and 133. For example, the partition (R) further includes information about the floating population and the resident population, and for areas with a large resident population, air quality management for the partition is performed more intensely in terms of health care of the resident population. It is also possible to set.

According to an embodiment, the controller 120 may differentially manage the air quality by reflecting the characteristics of the target space 10 called the underground space. In addition, not only the measured data is used but also the air quality in consideration of various factors including spatial characteristics such as the type and size of the space, the location of the air conditioning system 11, and external factors such as time, season, and floating population. Will be managed. As described above, by dividing the target space 10 into a plurality of divided regions R and managing the differential spaces R, the air conditioning system 11 can be appropriately operated according to the situation and the space, thereby improving the operational efficiency of the air conditioning system 11. It can be said to be effective in terms of the maintenance of the air conditioning system 11, including the improvement of the electric charge.

In addition, by weighting and measuring the measured data, it is possible to provide a plan for improving the air quality and operating the air conditioning system 11 more scientifically. In addition, by providing objective methodologies that are quantitative, including the assessment of air quality, and the improvement and evaluation of the results, it is possible to provide managers with objective guidance.

In addition, the air quality management system 100 may be provided with an integrated control platform (not shown) including a DB for storing measured results and information stored in the first to third information providing units 131, 132, and 133. Can be.

In addition, the air quality management system 100 may allow a manager to control the air conditioning system 11 through the control unit 120 and to view various measurement results from the air quality management system 100 (not shown). ) May be included. For example, the user device may be an operation panel of the air conditioning system 11 or may include various terminals that an administrator can carry. In addition, the air quality management system 100 may provide a management tool and an air conditioning control algorithm to constantly transmit information to an administrator by using an IOT technology and the like.

Hereinafter, an operation of the air quality management system 100 will be described with reference to FIG. 4. For reference, FIG. 4 is a flowchart illustrating an operation of the air quality management system 100 according to an exemplary embodiment. And the configuration of the air quality management system 100 refers to the description of Figs.

First, the target space 10 is set to a plurality of divided regions R1, R2, R3, and R4. For example, the divided regions R1, R2, R3, and R4 may be appropriately divided according to the size of the inside of the target space 10, and the amount of pollutants generated, whether the cleanness required in the space is high or low, and the air conditioning is performed. It is set in consideration of the positional relationship with the system 11 and the positional relationship with the entrance and exit, and may be set to a predetermined size or different sizes.

For example, in FIG. 2, the target space 10 is set to four divided regions R1, R2, R3, and R4. Each of the divided regions R1, R2, R3, and R4 has different amounts of pollutants generated by different purposes or conditions, and requires different cleanliness, and accordingly, each divided region R1, R2, R3, R4) is differentiated from each other to manage air quality. Meanwhile, this is merely an example, and the number and size of divided regions R1, R2, R3, and R4 of the target space 10 may be changed in various ways. In addition, even if the divided regions R1, R2, R3, and R4 are set to each other, at least some of the divided regions R1, R2, R3, and R4 may be managed to be identical to each other.

Next, the measuring unit 110 measures the air quality in each divided region (R1, R2, R3, R4) (S11).

The measuring unit 110 is provided at at least one or more positions in each of the divided regions R1, R2, R3, and R4, and includes one sensor or a plurality of sensors. In addition, the measurement unit 110 independently of the plurality of measurement data measured in each of the divided regions R1, R2, R3, and R4 according to a predetermined criterion set for each of the divided regions R1, R2, R3, and R4. Can be synchronized.

Next, the controller 120 weights the measured result using the information stored in the first to third information providing units 131, 132, and 133 (S12) and classifies the grades (S13).

The controller 120 synchronizes the plurality of measurement results measured in each of the divided regions R1, R2, R3, and R4 for each divided region R1, R2, R3, and R4, and each of the divided regions R1, R2, The weight is given according to the weight set in R3, R4) and is exponentialized. That is, the control unit 120 displays the spatial information set in the divided regions R1, R2, R3, and R4, the position information according to the position of the air conditioning system 11, and the external factor information of the target space 10 based on the measured result. It is weighted and considered exponential.

For example, the spatial information may include the number of partitions R1, R2, R3, and R4 included in the target space 10, the size, location, and type of each partition (R1, R2, R3, and R4). For example, information such as a restaurant, an office space, a resting room, and the like, and whether the divided regions R1, R2, R3, and R4 are entrances and exits, and location and distance from the entrances are included. In addition, the space information may also include information about the size, location and number of the doorways within the target space 10 and information about the spaces to which the doorways are connected (for example, whether they are connected to the outside or connected to other spaces). Can be. In addition, the spatial information may include various information including spatial characteristics of the target space 10 and the divided regions R1, R2, R3, and R4.

The location information includes information about the distance to the air conditioning system 11, for example, the location, distance, and number of the intake port 111 and the exhaust port 112 in the divided regions R1, R2, R3, and R4. can do. In addition, the location information may include various pieces of information related to the air conditioning system 11 that may affect the air quality of the target space 10 or the divided regions R1, R2, R3, and R4, such as output information of the air conditioning system 11. It may include.

The external factor information may include external weather, fine dust concentration, time, season, and floating population, which are measured directly or provided by an external institution. In addition, the external factor information may include various information that may affect the air quality of the target space 10 or the divided regions R1, R2, R3, and R4.

However, this is only an example, and in the classification of the weights and the grades in the controller 120, more factors may be considered in addition to the above-mentioned factors, and these considerations may include the first to third information providing units 131. , 132, 133 may be stored in other information providing units. For example, the partition (R) further includes information on the floating population and the resident population, and in areas where the resident population is large, the air quality management for the partition is performed more intensely in terms of health care of the resident population. It is also possible.

Next, the control unit 120 differentiates the divided areas (R1, R2, R3, R4) according to the grade determined as described above to manage the air quality (S14).

Here, the grade can be set higher for the case where the air quality should be kept more clean. For example, the rating may be set as Very Good / Good / Slightly Good / Medium / Slightly Bad / Bad. However, this is only one example, and it is also possible to set a high grade for good air quality (ie low demand for keeping the air quality clean).
For example, the control unit 120 controls the operations of the intake port 111 and the exhaust port 112, so that the outdoor air supply for supplying outdoor air to the room and the internal air circulation for circulating air in the room and the rapid exhaust for discharging the indoor air. The operation mode of the air conditioning system 100 can be adjusted. Also,

Next, the air quality is re-measured in the divided regions R1, R2, R3, and R4 according to a predetermined time or as needed, and then feedback and management.

First, the air quality is re-measured in the divided regions R1, R2, R3, and R4 after a predetermined time elapses or after a certain event occurs (S15).

If there is a change in the air quality more than a certain amount by comparing the re-measured result with the previously measured result (S16), the air quality of the corresponding partitions (R1, R2, R3, R4) is improved by weighting and grading again. The air conditioning system 11 is operated.

When performing the feedback, the feedback may be performed on the entire divided regions R1, R2, R3, and R4, or selectively performed only on regions of a predetermined grade or more (or below).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
