Germs and other bacteria grow on the inner surface of the ducts that form, as well as on the temperature control coils and filters installed during conditioned air supply operation.
特に、フィルターにおいては、通過風速が小であること
、並びに、フィルクー濾材が湿気を含むこと等に起因し
てカビ等細菌類の増殖が顕著である。In particular, in filters, the growth of bacteria such as mold is noticeable due to the low passing air velocity and the fact that the filter medium contains moisture.

る。However, the growth of mold and other bacteria in the conditioned air supply path becomes a source of contamination of the conditioned air supplied to the air-conditioned area, and in particular, the growing bacteria that separate from the filter are directly blown into the air-conditioned area. Sterilizing mold and other bacteria in the air supply path is extremely important in terms of hygiene in the air-conditioned area, and in terms of making the area dust-free if the area to be air-conditioned is a manufacturing work area for semiconductors or precision equipment. is important.

ことができない問題があった。Conventionally, in order to sterilize mold and other bacteria that have grown and grown in conditioned air supply channels, manual cleaning or formalin fumigation has been carried out with the conditioned air supply operation stopped, or areas where bacteria are likely to grow. An ultraviolet lamp was installed in the room to sterilize the food by irradiating it with ultraviolet light. (No references can be provided.) [Problem to be solved by the invention] However, in sterilization treatment by manual cleaning or formalin fumigation, use of the air-conditioned area must be stopped for a long period of time. , In the case of air-conditioned areas that are used continuously day and night for several months due to production or work schedules, or air-conditioned areas that need to be available at all times, such as operating rooms, etc. There was a problem in that the sterilization process could not be performed frequently enough.

った。On the other hand, with the method of installing an ultraviolet light lamp, sterilization can be performed during normal air conditioning operation without stopping the use of the area to be air conditioned, but depending on the shape of the object to be irradiated with ultraviolet light, many Furthermore, it is difficult to obtain a sufficient sterilization effect because it is impossible to irradiate the inside of the thick filter material.Moreover, when trying to sterilize a wide area of the conditioned air supply path, many It is necessary to install ultraviolet lamps in parallel, resulting in high equipment costs and complicated maintenance for each ultraviolet lamp.

り、その作用・効果は次の通りである。The characteristic means of the air conditioner sterilization method according to the present invention is to supply sterilizing gas to a conditioned air supply path during conditioned air supply operation to an area to be air conditioned, and adsorb the supplied sterilizing gas on the downstream side of the conditioned air supply path. It can be selected by some agents, and its actions and effects are as follows.
つまり、調和空気供給路に対して、調和空気と共に殺菌

イルやフィルター等の介装物、並びに、供給路形成ダク
トの内面を殺菌処理する。In other words, a sterilizing gas is passed along with the conditioned air through the conditioned air supply path, and the intervening objects such as temperature control coils and filters, as well as the inner surface of the duct forming the supply path, are sterilized. do.
そして、調和空気供給路の下流側において通過殺菌ガス
を調和空気から分離するように吸着剤により吸着除去し
、調和空気のみを空調対象域に吹き込み供給する。Then, on the downstream side of the conditioned air supply path, the passing sterilizing gas is adsorbed and removed by an adsorbent so as to be separated from the conditioned air, and only the conditioned air is blown and supplied to the area to be air-conditioned.
したがって、通常時とほぼ同等の空調運転状態で空調対
象域を使用しながら殺、画処理を行なえる。Therefore, image processing can be performed while using the air-conditioned area under air-conditioning operating conditions that are substantially the same as in normal times.

囲にわたって極めて高い殺菌効果を得ることができる。The sterilizing gas flowing through the supply path in a mixed state with conditioned air has a sterilizing effect on the entire inner surface of the duct forming the conditioned air supply path throughout the entire flow path, and also has a sterilizing effect on the entire inner surface of the duct forming the conditioned air supply path. Since the inside of a certain intervening object is reliably sterilized as it passes through, an extremely high sterilizing effect can be obtained over a wide range of the conditioned air supply path.

ナンスも紫外線灯設置よりは大巾に容易となる。Moreover, sterilizing gas is supplied upstream of the conditioned air supply path,
It is a relatively simple method that only adsorbs and removes sterilizing gas on the downstream side, so it is easier to work with than manual cleaning, etc.
In addition, the configuration of ancillary equipment for sterilization is simpler than the conventional arrangement of ultraviolet lamps lined up inside the conditioned air supply path, and maintenance of the ancillary equipment is also easier than installing ultraviolet lamps. becomes much easier.
