Description

Air quality management system

The following description is to provide an air quality management system using personal area network (PAN) communication.

As the industry develops, the environment is polluted, and as the quality of life increases, the desire to improve it is growing. However, the methodology for improving scientific and systematic air quality is still insufficient.

For example, the indoor air quality that most people live in, for example, through the conventional window, only through manual or automatic opening and closing operation of the indoor air is simply the extent to which the air is ventilated. If the window is completely closed and closed for crime prevention at nighttime, ventilation or removal of various harmful substances generated in the room becomes impossible, and various contaminants remain in the room, causing various problems.

Of course, some air cleaners have been used as a method to improve indoor air quality in the past, but there are natural limitations in improving indoor air quality due to their functions. In addition, since the measurement sensor that measures the numerical value is not attached, it is difficult for the occupant to check the amount of pollutants with the numerical value, making it impossible to efficiently manage and improve air quality. In addition, it is said that the degree of partial air quality improvement depending on the sense is being carried out, such as the environment is not being improved in connection with other control or cleanliness. Particularly, when the air purifier is turned on for a long time, the amount of ozone (25%) emitted along with anions (about 75%) continues to increase, and the occupants actually inhale excessively supplied organic compounds.

However, due to the development of the industry, the improvement of the cultural level and the enrichment of life, interest in health has been increasing recently, and moreover, everyone is the most important and important factor in human life. This is a undeniable fact. However, in our current living space, many pollutants emitted from vehicles and industrial facilities, and harmful substances from household goods such as construction materials, furniture and electronics made of petroleum and chemical materials threaten human health. However, the reality is that the seriousness is gradually increasing.

In particular, humans live about 80% or more in a limited indoor space for 24 hours a day, and in this process, polluted air is continuously generated, and the polluted air indoors must increase the pollutant concentration. . At this time, if the indoor pollutant concentration is not properly adjusted or improved, human beings have no choice but to breathe unconsciously contaminated air while living without compromising their health.

There are about 250 types of substances that pollute indoor air, including very small substances. Among them, in view 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 indoor building materials, etc. There is this. In addition, in human activities, carbon dioxide (CO2), dust, cigarette smoke, foot odor and microbial substances in various household products generated during ignition of gases or breathing processes of the human body when cooking food in the kitchen ( E. coli, Pseudomonas aeruginosa, 0-157, Salmonella) and volatile organic pollutants, and other odors, noise, and radiation. It is well known that these various harmful substances cause various adverse effects on the human body such as skin allergies, respiratory diseases, and headaches.

Here, the pollutants generated from various construction materials can be naturally extinguished within about 1 to 5 years when the indoor pollution level is below an acceptable standard. Even in this case, it is a problem to improve the air quality until it falls below the standard concentration (1000 ppm or less based on CO2) suggested by the Public Sanitation Management Act and the Construction Act. In addition, harmful substances such as various carbon dioxide generated in human activities cannot be eliminated. These are indispensable substances on an ecological and environmental level.

Therefore, above all, various harmful substances generated from human activities are set to the appropriate standard value, and when they are generated above this allowable standard level, the indoor air quality is lowered below the allowable standard level even if the occupants are present immediately or the window or doorway is closed. It is very important to improve it. This is because carbon dioxide generated from human activities is not properly designed to naturally circulate indoor air due to the structure of our homes. Therefore, if natural circulation of harmful air cannot be achieved, the occupants eventually get more carbon dioxide than appropriate oxygen through breathing. Inhale. In severe cases, problems occur that cause dyspnea or serious disability in brain movement.

However, the domestic housing construction industry has not been able to find a way to improve air quality, especially in relation to housing, and in recent years, public interest in the environment has increased. In the meantime, as the “Indoor Air Quality Management Act” was enacted to take effect from 2004.06, it was expanded to multi-use facilities such as underground stations, underground shopping malls, passenger terminals, libraries, and general hospitals, and newly built multi-unit apartments. The company is managing indoor air quality and improving the living environment through strong measures such as public announcement.

However, the reality has not been able to keep up with these human needs. In the case of various products having sterilization, deodorization, and air cleaning functions that are used to improve various air quality in the past, the air quality sensed is simply measured by the sensor. It is not managed by checking. First of all, it is impossible to efficiently manage indoor air quality because occupants cannot see and feel the degree of indoor air quality with their own eyes.

In order to propose such a comprehensive environmental improvement method, it is urgent to develop a methodology for comprehensive improvement work, starting with an index for sensor values or evaluation values.

The contents described as the above-mentioned background art are possessed or acquired in the process of deriving the present invention, and cannot be said to be recognized as a publicly known public technology prior to the filing of the present invention.

In addition, the control unit 140 may selectively operate on/off and operation modes of the air quality management device 110 according to the control information 134. Here, the operation mode means that the clean function of the air quality management device 110 is strong/medium/weak, etc., and operates based on the strength and weakness, or an operation for removing specific pollutants. In addition, the control unit 140 controls to perform any one of the operation modes of the air quality management device 110 according to the control information 134.

In addition, the control unit 140 may operate the air quality management device 110 differentially with respect to the plurality of control areas R. When the air quality management device 110 is operated according to the information of the database 130 in each control area R, it is also possible to manage each control area R differentially and independently.
