The present invention relates to purifying and ventilating air in an enclosed indoor living space, such as an apartment, and more particularly, volatile organic compounds, odorous substances, dust, carbon monoxide, generated from combustion sources, smoking gases, furniture, etc. An apparatus and method for the removal of carbon dioxide, nitrogen oxides and the like.

Existing air purifier sucks some indoor air and discharges it to the room after purification. As shown in Figs. 2 and 3, only a part of the air is purged to lower the purification capacity and the indoor space is not purified by the air purifier. There is a disadvantage that a lot of dead space does not occur. In addition, fatal problems have been pointed out, such as inability to purify indoor air pollution caused by yellow dust. This is because when the air is hardly purged and the room is sealed during ventilation, dust collection and adsorption methods do not remove carbon monoxide, nitrogen oxide, and carbon dioxide generated in the room.

Currently, the air purification method of indoor space is composed of dust collecting filter or electrostatic filter, adsorption filter, anion generator, etc. However, this method can remove only dust, some odorous substances, organic compounds, etc. Carbon monoxide, nitrogen oxides, and the like are not removed. Indoor air environment is generally poor in ventilation and contaminants generated in food, smoking, furniture and clothing coating materials. Therefore, the concentration of carbon monoxide, volatile organic compounds, carbon dioxide, nitrogen oxides, dust, etc. Is high is reality.

General household air purifiers are installed to improve indoor air environment. The domestic air purifiers are installed through dust collection and adsorption methods, or catalysts and ozone methods are used to remove dust, odors, VOCs, etc. Due to the high level of pollution in the environment, the equipment is complicated and the quality of the purified air is low. In addition, the adsorption method exhibits superior performance in the early stage, but when the amount of the adsorbent is exceeded, the air quality is rather deteriorated, and when it is not replaced regularly, there is a problem of deteriorating the air quality such as microorganisms propagating on the filter layer.

Also, as shown in FIG. 2 and FIG. 3, it is difficult to purify the entire air in the room by sucking and treating the indoor air, and ozone, which is a representative substance of anion, is more likely to be concentrated in the indoor space. In addition, there is a problem that the indoor air is further deteriorated when the regular filter replacement is not made.

In addition, since outdoor air is generally higher in cleanliness than indoor air, the method of purifying air after sealing itself acts as a deterrent to indoor air environment.

The present invention is to quickly discharge the pollutants generated in the indoor living space to the outside and to purify by sucking the outside air to reduce the nitrogen dioxide, nitrogen monoxide, nitrogen oxides, etc. that are not purified in the conventional way in the room and to clean the outside air indoors There is a technical problem in providing a device and a method for performing a combination of air purification functions by supplying the space.

The present invention is a method of sucking the outside air and supplying it to the room after purification. As shown in FIG. 1, the air purifying apparatus 3 is located in a place where air can be ventilated, for example, a door, a window, an indoor exhaust port, or a suction pipe is installed to suck and purify the outside air to supply the room. The purified air supplied to the room is discharged to the outside through the windows 6, the exhaust ports 5, etc. installed in the room. In this way, air pollutants are essentially blocked from entering the room, and the pollutants generated in the room are quickly exhausted to the outside to maintain a pleasant environment at all times. Carbon monoxide, carbon dioxide, and nitrogen oxides generated from indoor combustion sources or smoking are materials that are difficult to purify with conventional air purifiers, which can be controlled through continuous ventilation. Therefore, the present invention keeps the room always comfortable by keeping air purification and ventilation continuously.

The air purification system consists of a blower, a primary prefilter, a secondary HEPA filter, a tertiary adsorption activated carbon filter, a quaternary sterilization filter, anion generator, a distribution pipe, and an operation device. External air drawn through the blower removes particulate matter below PM10 through primary and secondary dust filters, and then removes organic compounds and odorous substances through adsorption activated carbon filters. Adsorption activated carbon filter can decompose ozone into carbon dioxide, carbon monoxide, etc., which have less effect on human body when ozone concentration is increased due to photochemical smog. In addition, the sterilization filter of the final stage is silver plated to sterilize with silver. In addition, an anion generator is installed to remove indoor odors, and if the driver starts manually, it is configured to purge the indoor ozone lamp to the outside with a ventilation time after the anion is generated.

The indoor air purification performance of this device was compared with the degree of air purification before and after using the purification device after 26 days in a 26-flat apartment.

Table 1 shows the concentrations of major indoor pollutants before using the air purifier. Table 2 shows the concentrations of major indoor pollutants after using the air purifier for three days.

By purifying the indoor air according to the present invention, the air purifier is simple and exhibits a ventilation effect, thereby keeping the indoor air clean.
