PROBLEM TO BE SOLVED: To prevent indoor condensation of a decontaminating gas.SOLUTION: The indoor decontaminating gas concentration C is adjusted at a set goal concentration Cm by adjusting the input quantity Lg, per unit time, of an aqueous decontaminant solution W into a decontaminating gas generator 2 so as to adjust the quantity Vg of the decontaminating gas G generated per unit time, whereas the gain magnitude xg, per unit time, of the indoor humidity x is computed in this concentration-adjusted state based on the input quantity Lg, per unit time, of the aqueous decontaminant solution W so as to determine whether or not the condensation of the indoor decontaminating gas G will occur during the decontaminating operation based on the computed value of the gain magnitude xg, per unit time, of the indoor humidity x and on the concomitantly measured value of the indoor humidity x, and in a case where the condensation of the indoor decontaminating gas G is determined to occur during the decontaminating operation, the indoor space of a target room 1 is dehumidified by operating a dehumidifier 3, whereas in a case where the condensation of the indoor decontaminating gas G is determined not to occur during the decontaminating operation, the operation of the dehumidifier 3 is stopped. |
