Abstract: PURPOSE:To more completely remove dust with a small quantity of circulating air and good energy efficiency by humidifying air current before rapidly cooling it to the dew point or less to dew it to remove dust. CONSTITUTION:After contaminated circulating air from a clean room 10 is humidified by a humidifier 11, it is introduced into an evaporator 1 3 by a fan 12. In the evaporator 13, the refrigerant of an air conditioning system is expanded and evaporated inside a multistage heat exchanger 37 and the circulating air coming in contact with the heat exchanger 37 is rapidly cooled.

At this time, since it is easier for the water vapor to form dew using dust in the circulating air as nuclei, the mist and dew are discharged to the outside of the system, attaining the cleaning of the circulating air. Namely, the water droplets accumulated in the bottom of the evaporator 13 are discharged as drain through a drainage 17.
