STRUCTURE OF DECONTAMINATION OBJECT ROOM AND METHOD FOR REDUCING CONCENTRATION OF DECONTAMINATION AGENT

摘要

PROBLEM TO BE SOLVED: To provide the structure of a decontamination object room capable of swiftly reducing the concentration of a decontamination agent in the decontamination object room to an allowable concentration.SOLUTION: The structure of a decontamination object room (10) comprises: a measurement part (11) of measuring the temperature of the air in the decontamination object room; an air-conditioning machine (12) of feeding clean air to the inside of the decontamination object room; and a control part (13) of controlling the air-conditioning machine in such a manner that clean air at a temperature higher than the temperature measured in the measurement part is fed to the inside of the decontamination object room after the passage of a fixed time after the concentration of a decontamination agent in the decontamination object room starts to be reduced.
