Abstract

In the conventional fumigation of the rooms required to be sterilized, formaldehyde is general used, but formaldehyde has such problems as carcinogenicity and residual tendency. It is also proposed to combine fumigation and air conditioning for automation, but air conditioning and fumigation cannot be performed concurrently. The present invention proposes an air conditioning system for the rooms required to be sterilized, comprising an air conditioning path consisting of an conditioned air supply path extending from the discharge side of an air conditioner to the air supply openings of the rooms required to be sterilized and an indoor air suction path extending from the air suction openings of the rooms required to be sterilized to the suction side of the air conditioner; a bypath for bypassing the air conditioner; an ozone supply path extending from an ozone generation unit to a switching mechanism and further branching into the ozone supply paths connected with said conditioned air supply path and said bypath; an ozone decomposition path with an ozone decomposition unit, in parallel with the bypath; an air discharge path with an air discharge fan, connected with said indoor air suction path or with the rooms required to be sterilized; and a switching mechanism for switching between said air conditioning path, said bypath, said ozone decomposition path and said air discharge path.
