Description

Oxygen generation system for supplying oxygen to multiple indoor areas { OXYGEN GENERATION SYSTEM FOR SUPPLYING MULTIPLE INDOOR AREAS }

The present disclosure relates to an oxygen generating system, and more particularly, to an oxygen generating system for supplying oxygen through a plurality of discharge devices so that the oxygen concentration of each of a plurality of indoor areas is equal to or higher than a target oxygen concentration.

Oxygen generation system (oxygen generator) is a system that removes pollutants and nitrogen in the air, extracts only oxygen, and supplies it indoors.

The oxygen generating system can be implemented in various ways. The catalyst method has the disadvantage of requiring replacement of the catalyst every time, the electrolysis method has the disadvantage of generating highly explosive hydrogen, and the gas separation method has the difficulty of manufacturing products. The downside is that it is quite high.

On the other hand, the PSA (Pressure Swing Adsorption) method adsorbs nitrogen molecules and various substances in the air through adsorbents such as zeolite (Zeolite Molecular Sieve) and then extracts only oxygen. The cost of oxygen generation is economical and easy to generate continuously. That is, it is the most commonly used method. In addition, the RVSA (Rapid Vacuum Swing Adsorption) method is also used, which is similar in basic principle to the PSA method, but in which only the order of adsorption and compression is changed.

Such a conventional oxygen generating system cannot supply oxygen to only one indoor area or to supply oxygen to a plurality of indoor areas, but cannot supply oxygen of different oxygen concentration to each of the plurality of indoor areas according to the air condition of each of the plurality of indoor areas. There is a problem.

The control device 300 may control the supply of oxygen through the outdoor device 100 and the plurality of discharge devices 200 so that the oxygen concentration of each of the plurality of indoor areas is equal to or higher than the target oxygen concentration of each of the plurality of indoor areas.

First, the control device 300 receives the oxygen concentration of each of the plurality of indoor areas from the plurality of outdoor devices 100, and the first indoor area in which the oxygen concentration among the plurality of indoor areas is less than the target oxygen concentration set for each of the plurality of indoor areas can confirm.

Then, the control device 300 may estimate the volume of the indoor area of the first indoor area where the oxygen concentration is less than the target oxygen concentration.

To this end, the control device 300 receives a distance measurement value that is a separation distance from an object measured from the detection sensor 250 of the first discharge device 200 disposed in the first indoor area, and uses the distance measurement value. Thus, the volume of the indoor area of the first indoor area may be estimated.

In this case, the control device 300 may calculate the insufficient oxygen amount by multiplying the indoor area volume and the oxygen concentration difference.

Next, the control device 300 may calculate the first air discharge amount per unit time of the first discharge device 200 supplying the first air containing oxygen to the first indoor area among the plurality of discharge devices 200 . .

At this time, the control device 300 determines the cross-sectional area of the discharge pipe of the first discharge device 200 through which the first discharge device 200 communicates with the first indoor area and the first air flows, and the first discharge device 200. The aforementioned first air discharge amount per unit time may be calculated by multiplying the flow rate of the first air flowing through the discharge pipe.

To this end, the first discharge device 200 may include a flow rate sensor that measures the flow rate of the first air flowing through the discharge pipe of the first discharge device 200 .

Then, the control device 300 may calculate the first oxygen discharge amount per unit time of the first discharge device based on the oxygen concentration of the first air and the first air discharge amount per unit time.

Subsequently, the control device 300 determines that the oxygen concentration in the first indoor area is equal to or greater than the target oxygen concentration in the first indoor area by using the insufficient amount of oxygen in the first indoor area and the first oxygen discharge amount per unit time of the first discharge device 200. The time required for this can be calculated.

Specifically, the control device 300 may calculate the required time by dividing the insufficient oxygen amount in the first indoor area by the first oxygen discharge amount per unit time of the first discharge device 200 .

Thereafter, when the required time exceeds the standard required time set in the first indoor area, the control device 300 sets the first target air discharge amount per unit time of the first discharge device 200 such that the required time is equal to or less than the standard required time. can

In detail, the control device 300 may set a value obtained by dividing the amount of insufficient oxygen in the first indoor area by the reference required time set in the first indoor area as the first target air discharge amount per unit time of the first discharge device 200 .
