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 manage the air quality of the target space by reflecting the facility information and human information of the target space.

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 the scientific and systematic air quality is insufficient.

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, there is no improvement in the environment in connection with other control or cleanliness. In particular, when the air purifier is turned on for a long time, the amount of ozone (25%) released along with the anion (about 75%) continues to increase, causing the inpatient to inhale excessively supplied organic compounds.

However, due to the development of industry, the improvement of culture level, and the benefits of living, the interest in health has been increasing in recent years, and moreover, health is the most important and important factor in human life. It is an undeniable fact. However, in our living spaces, many pollutants generated from vehicles and industrial facilities, as well as harmful substances from household goods such as building materials, furniture, and electronics made of petroleum and chemical-related materials, threaten human health. In reality, the seriousness 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 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, above all, it is recommended to set the appropriate standard value for various harmful substances generated in human activities so that the indoor air quality is lowered below the acceptable standard value even if the occupants are occupied or the window is closed. 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 “Air Quality Management Act” was enacted 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 apartment houses. Through strong measures, such as the management of indoor air quality and improving 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.

Therefore, the control method should be selected according to the control environment or the area within the environment, and control should be made by examining the relationship with other environmental improvement requirements such as air quality improvement.

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 values or evaluation values.
