Therefore, in order to maintain good hygiene in these rooms, disinfection is performed with chemicals. It was However, the conventional disinfection method has a main purpose of exterminating harmful small insects, and is a method of atomizing a chemical solution by a power sprayer or a human power sprayer and spraying it into a room. In many buildings, disinfection is performed for each room, which is very troublesome.

を特徴とする。Means for Solving the Problems As a result of earnest research to achieve the above object, the inventors of the present invention have found that bacteria in the air are adsorbed by a mist of water, and indoors such as in buildings, airplanes and ships. Paying attention to the fact that an air conditioner is installed, by ejecting a bactericide containing water from the air outlet of the air conditioner into the room, it is possible to effectively sterilize the room in an extremely short time, and also inside the air conditioner. Since they are sterilized at the same time, they found that the interior of the room is unlikely to be contaminated even after sterilization, and arrived at the present invention. That is, the present invention, from the rear of the air filter of the central type air conditioner, sprays a bactericide containing water in the form of mist, operates the air conditioner, the mist bactericide, from the air outlet through a duct It is characterized by being ejected into the chamber.

る。As the water-containing germicide used in the present invention, it is preferable to use an aqueous solution of ethanol, isopropanol, paraaldehyde or the like. From the point of flammability, it is preferable that ethanol and isopropanol have a concentration that does not pose a risk of ignition, for example, 30% or less. However, if the concentration of ethanol is 30% or less, the bactericidal power is reduced. Therefore, in order to prevent the reduction of the bactericidal power, glycine, glycerin fatty acid ester, phytic acid, thiamine lauryl sulfate, It is preferable to add one or more compounds selected from the group consisting of citric acid, acetic acid, lactic acid, tartaric acid, succinic acid, malic acid and phosphoric acid. By adding such a compound,
Even at a concentration of about 0%, it exhibits practically sufficient bactericidal power. As described above, when the concentration of ethanol is 30% or less, the odor of ethanol can hardly be sensed, and it is particularly suitable for sterilization of buildings such as hospitals and hotels where people are always occupied.

することもできる。Generally, in an air conditioner of a building, regardless of the size of the building, the air can be circulated once in about 7 to 10 minutes. The water-containing bactericidal agent of the present invention is sprayed in the form of mist for one circulation time,
It is preferable to stop spraying the air conditioner and the bactericide in one circulation for 7 to 10 minutes, and let it stand as it is. This is because if the mist is further circulated after spraying, the mist will be captured by the air filter of the air conditioner, which is not preferable. To spray a water-containing bactericide as a mist from the rear of the air filter, spray with a sprayer, automatically spray from a cylinder containing a carrier such as carbon dioxide, or humidify. Depending on the position of the container, it is also possible to spray from the humidifier.

れば良い。In the method of the present invention, it is preferable that the air filter of the air conditioner holds the bactericide containing water before and / or during the spraying of the bactericide in the form of mist. . By doing so, since the bacteria in the air have a property of adhering to water, the bacteria are captured by the air filter and sterilized, and the bactericide containing water is dissolved in the air, so that the mist is dissolved in the air. Hard to do. In order to allow the air filter of the air conditioner to hold the bactericide containing water, the sterilizer may be held directly in the air filter or the sterilizer may be held in a suitable air filter medium. As the filter material, for example, fibrous activated carbon, cloth, glass fiber, asbestos fiber or the like can be used. Since the fibrous activated carbon itself has a property of adsorbing bacteria in the air, it is particularly preferable to use fibrous activated carbon for the purpose of removing bacteria. In order to retain the sterilizing agent in a suitable air filter medium fixed directly to the air filter or fixed to the air filter, by the same method as sprayed as the mist,
A bactericide containing water may be sprayed on the air filter or the filter medium at regular intervals so as not to dry.

The air in the room in the m 2 building was sterilized. First, the air in the room was sterilized by operating the air conditioner for 1 hour while spraying the fibrous activated carbon 15 with the aqueous sterilizing agent solution every 3 minutes. still,
The air in the room was returned from the return 9 to the inside of the air conditioner 1, and was circulated once between the room and the air conditioner 1 for 10 minutes. Then, from the germicide sprayer 18, the germicide solution was misted and sprayed for 10 minutes, the air conditioner was operated, and the mist was introduced into the room through the air outlet 8. During this period, fibrous activated carbon 1
Spraying of No. 5 with bactericide was continued. In this way, room 7
It was confirmed that the inside and the inside of the air conditioner 1 were completely sterilized. The duct in the air conditioner also sucks in the air above the ceiling of the building, and the air also enters the space above the ceiling, and the bactericide mist circulates also inside the ceiling, so the air behind the ceiling is also sterilized at the same time. The method of the present invention can be applied to sterilization of vehicles such as trains as well as buildings, ships and aircraft. In short, any room can be used as long as the air of the air conditioner circulates.

ができる。As described above, according to the present invention, the air conditioner is used to spray the aqueous solution of the sterilizing agent as mist into the room, so that the aqueous solution mist is effectively adsorbed by the bacteria, which is effective. In addition to being able to sterilize, it is possible to disinfect in every corner of the room effectively in an extremely short time regardless of the number of rooms, so the disinfection cost in the room can be significantly reduced and conventional disinfection can be performed. Since it is possible to disinfect the inside of the air conditioner and the attic, which has never been done, re-contamination of the room due to bacteria etc. inside the air conditioner is also prevented, so it is possible to always keep the room low in bacteria, etc. It has a tremendous effect not found in any method. In addition, if a disinfectant that is completely harmless to the human body is used, such as an aqueous ethanol solution, it can be sterilized without any trouble even when there are people in the room, so it is particularly effective for disinfecting hospitals, hotels, etc. . Further, if the air filter holds the aqueous sterilizing agent solution and the air in the room is allowed to pass through this air filter, the bacteria are adsorbed by the water, so that the air can be effectively sterilized. And the sterilization rate in the duct can be significantly improved.
