Description

Ventilation clean air supply device

The present invention relates to a ventilation clean air supply device.

In general, houses, apartments, or offices are designed and constructed in a closed structure to improve cooling, heating and noise blocking functions, so that indoor air or outside air cannot circulate indoors and outdoors, so fine dust or ultra-fine dust introduced through various routes. There is a problem that fine dust (hereinafter referred to as “fine dust”) accumulates indoors.

Such fine dust is transported to the lungs by breathing, and air is released from the lungs to the outside world. In this process, the fine dust continues to accumulate indoors and in the body, ultimately damaging the health of the human body.

In addition, harmful exhaust gases (hereinafter referred to as “fine dust”) such as smoke generated when cooking food, odor in the bathroom, cigarette smoke, carbon monoxide, carbon dioxide, and rust are generated indoors, and fine dust introduced from the outside and indoors There is a problem that various diseases are caused by the generated fine dust.

In particular, in recent years, fine dust caused by various emission sources is progressing to a serious level so that it becomes a social problem.

Conventionally, even though ventilation is required to prevent the inflow of heavy external dust or polluted air, there have been cases in which windows cannot be opened at all. Although a conventional air purifier was developed to purify indoor air, it is a method of inhaling indoor air containing fine dust that is introduced from the outside and generated indoors, and then discharging it back to the room. By purifying only the air, the purification capacity is deteriorated, and there are disadvantages that there are many dead spaces that cannot be purified by the air purifier.

In addition, fatal problems have been pointed out, such as inability to purify indoor air pollution caused by yellow sand.

This is because air purification is hardly performed during ventilation, and there is a limitation in removing particulate carbon monoxide, nitrogen oxides, carbon dioxide, etc. by dust collection and adsorption when the room is sealed.

The air purification method of such an indoor space is currently composed of a dust collection filter or an electric dust collection filter, an adsorption filter, and an anion generating device, but this method can only remove dust, some odorous substances, and organic compounds. There is a problem that even a person indoors inhales dust, some malodorous substances, and organic compounds through breathing at the same time.

The indoor air environment is generally poorly ventilated and the concentration of carbon monoxide, volatile organic compounds, carbon dioxide, nitrogen oxides, dust, etc. compared to the outside air environment due to pollutants generated from food cooking, smoking, and painting materials on furniture and clothing. It is a reality that is high.

General domestic air purifiers installed to improve the indoor air environment are intended to be improved through dust collection and adsorption methods, or to remove dust and odors by using catalysts or ozone, but the pollution level of indoor air environment is high. Therefore, the device is complicated and the quality of the purified air is low.

In addition, the adsorption method shows superior performance at the beginning, but when the adsorption amount of the adsorbent is exceeded, the air quality is rather deteriorated, and when it is not replaced regularly, there is a problem that the air quality is further deteriorated, such as microorganisms multiply on the filter layer.
