Description

[0001] The present invention relates to an indoor air pollutant emission control system having an indoor air pollutant emission control function,

[0001] The present invention relates to a radon gas and pollutant exhaust control system installed in a building, and more particularly, to a system for controlling a radon gas and a pollutant discharged from a building, The present invention relates to an indoor pollutant emission control system having a radiation radon gas emission preventing function capable of effectively preventing indoor residents from harmful environmental pollutants by effectively discharging air pollutants such as dust,

Among the various environmental pollutants known to be harmful to human body, radon gas, which is one of the environmental radiation directly inputted from the ground, and dust or fine dust introduced by the flow of the air, are attracting the most attention in recent years .

Among these, radon is one of the environmental radiation generated by uranium decay, and it is known as a primary carcinogen that generates lung cancer by radiation exposure because it has a colorless odorless gas state and is absorbed by the human body by respiration. It flows into the room through the cracks of the building from the ground, but it is also generated from the uranium decay contained in the cement, soil, and other internal and external materials used in the building construction, and is introduced into the room.

In order to reduce the radon gas introduced into the room, it is necessary to rely only on periodic ventilation by residents. However, since the ventilation is not performed properly in the case of a cold winter or sleeping night, residents are exposed to radon gas, .

In order to solve such a problem, recently, a technique of installing a radon gas degassing apparatus in a ground or soil near a building has been developed in order to fundamentally reduce the radon gas introduced into the room. The contents are disclosed in detail in the following document [1].

However, even in the case of the technique according to the following [Document 1], since all the radon gas generated in the ground is not introduced into the deaerator installed near the building, the radon gas flows into the room through the minute cracks formed on the bottom surface of the building It is not possible to prevent such a problem.

In the case of the technique according to the following [Document 1], since only the radon gas generated in the ground is deaerated, the uranium decay contained in the cement or the soil used in the construction of the building inflows into the room from the wall of the building or the inside / There is a problem that the radon gas can not be reduced at all.

Further, in the case of the technique according to the following [Document 1], air pollutants such as dust and fine dust in the air, which have recently been seriously problematic due to the presence of harmful heavy metals, are prevented from entering the room through the windows or through the entrance Therefore, it is urgent to take measures to solve the problems of the conventional art as described above.

The detailed operation of the indoor pollutant emission control system having the radioactive radon gas exposure prevention function according to the present invention will be described in detail with reference to the flow chart of FIG.

First, the control unit 100 receives the operation signal and the operating condition of the control system through the input unit 110, receives the operation signal and the operating condition of the control system, and operates the first exhaust fan 60 according to the received operating condition S20).

In this case, the operation condition may include an operation cycle and an operation time of the first exhaust fan 60. Such an operation condition may be input directly by the user or stored in advance as a set value of the control system .

When the step S20 is completed, the control unit 100 measures the air pollution level of the indoor space using the air pollution degree sensor 120 (S30), and determines whether or not the air pollution degree measured in step S30 is equal to or greater than a predetermined reference value. Determine (S40).

In this case, the air pollution sensor may be preferably implemented using a conventional air quality measuring device for measuring the concentration of carbon dioxide, the concentration of nitrogen dioxide, the concentration of fine dust, the concentration of heavy metals, etc., on one side of each indoor space Can be installed.

In addition, the reference value may be a concentration value of any one of the pollutants (concentration of fine dust in this embodiment), and is set to a harmless concentration value for the pollutants as data published by the Korea Meteorological Administration .

If it is determined in step S40 that the air pollution degree is equal to or higher than the reference value, the controller 100 determines that contaminants such as yellow dust or fine dust are flowing from the outside into the indoor space, operates the air compressor 50 (S50) , The first opening / closing member 57 is opened to allow the compressed air to flow into the indoor space, so that the air pressure inside the indoor space becomes higher than the external air pressure (S60).

When the air pressure inside the indoor space is higher than the outdoor air pressure, inflow of outdoor air by the pressure difference is prevented, so that contaminants such as yellow dust and fine dust can be prevented from entering into the indoor space do.

In step S70, the controller 100 measures the air pressure inside the indoor space using the indoor air pressure sensor 130. When the indoor air pressure measured in step S70 is lower than the indoor air pressure measured in step S70, It is determined whether or not it is equal to or higher than a predetermined reference pressure (S80).

At this time, the indoor air pressure detection sensor 130 may be implemented using a conventional pressure gauge or the like, and may be installed at one side of each indoor space.

If it is determined in step S80 that the indoor air pressure is equal to or higher than the reference pressure, the control unit 100 operates the second exhaust fan 70 in step S90, and opens the second opening / closing member 77, So that the introduced air contaminants are discharged to the first flow path 2 through the second flow path 75 (S100).

The air pollutant discharged into the first flow path 2 is discharged to the outside of the room by the first exhaust fan 60 together with the larding gas.

At this time, it is preferable that the reference pressure is set to a pressure higher than the atmospheric pressure so as to prevent the backflow of the radon gas of the first flow path 2 in the atmospheric pressure state when the second opening and closing member 77 is opened.

On the other hand, if it is determined in step S80 that the indoor air pressure is lower than the reference pressure, the controller 100 repeats step S70.

When the step S100 is completed, the controller 100 determines whether a signal for terminating the operation of the exhaust device is input from the user (S110). If the determination result is negative, the control unit 100 repeats the operation of step S30.

On the other hand, if it is determined in step S110 that a signal for terminating the operation of the exhaust system is inputted, the controller 100 stops the operation of the air compressor 50, the first and second exhaust fans 60 and 70 Closing the first and second opening and closing members 57 and 77, and terminating the control (S120 and S130).

On the other hand, if it is determined in step S40 that the air pollution degree is less than the reference value, the controller 100 performs step S110.

According to the present invention, the indoor pollutant emission control system having the function of preventing radioactive radon gas exposure according to the present invention is configured to control the indoor air pollutant emission control system of the first exhaust fan So that it is possible to minimize exposure of residents to lardon gas.
