The present invention relates to a method for disinfecting indoor air. ｛゜し゛とーーa: Hospital operating rooms, patient rooms, consultation rooms, intensive care units, kitchen rooms, inside ambulances, operating rooms, examination rooms in hospitals, etc.The air inside examination rooms in hospitals, schools, etc. Preferably, it is sterilized. However, conventionally, in addition to high-pressure steam sterilization using heat, chemical sterilization methods such as spraying ethylene oxide gas or horn marine gas have been widely used for indoor or vehicle interiors. The disinfection method must be carried out by spraying a chemical solution into the room and keeping the room sealed for a long period of time (6 to 12 hours). By the way, the chemical solution used for spraying has a strong irritating odor, which not only harms the health of the person handling it, but also causes strong irritation to the eyes and nose even after a long period of disinfection. In addition, nosocomial infections due to resistant bacteria may occur. Furthermore, during that time, entry is restricted and effective use is severely restricted.

。Furthermore, if the spray liquid gets mixed into indoor MEs and equipment, there is a problem in that it causes deterioration and corrosion of circuit components, causing failures such as poor connections and short circuits. Although it is possible to sterilize indoor air by installing an ozone generator indoors, the smell of ozone is strong, and ozone itself is not necessarily harmless to human health. The inventor of the present invention has discovered that when an ultraviolet irradiation device and an ozone generator are installed indoors, the indoor air is sterilized unexpectedly, and almost no ozone odor is generated. That is, the present invention relates to a method for sterilizing the indoor air by placing an ultraviolet irradiation device and an ozone generator indoors or in a vehicle, and simultaneously generating ozone while irradiating ultraviolet rays. The ultraviolet irradiation device used can be a publicly known commercially available one.As a rough guide, for example, a 30 watt ultraviolet irradiation device can be used in a room with an area of 1 to 100 tsubo.Ozone generators are also known. A commercially available one can be used. Generally, the capacity of the ozone generator is 0.05W per hour.
