To a harmonic system.

Generally, a residential building such as an apartment or an office-use high-rise building is provided with an air conditioning system for ventilation of the room and periodically ventilates indoor air and outside air to maintain a pleasant indoor air, So that the air is exhausted to the outside of the building.

Particularly, dust, PM10, CO2, HCHO, total airborne bacteria, CO, NO2, TVOCs and ozone which are present in the air in underground history, underground shopping mall, airport terminal, Techniques have been developed and used to quickly and efficiently decompose and remove harmful gases and bacteria in the air by using a filter incorporating an area-increasing catalyst and an ozone decomposition catalyst. However, ozone is generated mainly by an ozone generator The amount of ozone to be used is relatively large, so that a large amount of ozone used for decomposing the gas and the bacteria is left, so that secondary contamination by harmful ozone occurs.

In addition, the typical atmospheric carbon dioxide concentration is about 400 ppm, but the indoor concentration can increase rapidly. For example, a carbon dioxide concentration of 700 ppm does not have a health problem even if it stays for a long time, but at a carbon dioxide concentration of 1,000 ppm People start to feel uncomfortable. At over 2,000 ppm, the human body feels fatigue such as drowsiness, headache and dizziness. Therefore, it is necessary to keep the concentration of carbon dioxide in indoor air below 1,000ppm.

In addition, 4 of the 10 people experienced drowsiness driving, and 19% of them have experienced 'a car accident' which is likely to cause an accident.

The reason for the inadequate air quality of the express bus is that it is a difficult environment to ventilate structurally due to insufficient operation of the ventilation system. There is ventilation on the ceiling of the driver's seat and ventilation system on the upper side of the vehicle. Can not do it. In addition, there is no system to control during operation, so it is inconvenient to operate.

Therefore, in most cases, when the electron e-is excited, the hole h + receives electrons from volatile organic substances contained in the air or contaminants such as cigarette smoke and oxidizes and decomposes these contaminants. In the case of volatile organic compounds, they are oxidized and removed by water (H2O) and carbon dioxide (CO2) as shown below.

VOC (Volatile Organic Compound) → CO2 + H2O
