PROBLEM TO BE SOLVED: To provide a system of ozone deodorization capable of automatically adjusting the flow rate and ozone concentration of dilute ozone gas intermittently blown toward plural blocks one after the other to prescribed values, and capable of easily maintaining the indoor ozone concentration within a range not exceeding an allowable value. SOLUTION: A prescribed number of blow-off nozzles 6 are mounted in each of plural blocks 1-4 into which an indoor space is divided, and the dilute ozone gas comprising air fed from an air compressor 7 mixed with ozone fed from an ozone generator 23 is intermittently blown off from the nozzles of each block one after another via a manifold 9. The air compressor 7 is controlled via an inverter 22 by a control device 21 so that the pressure detected by a pressure gauge 12 mounted in the manifold is a prescribed value, and the flow rate of ozone generated by the ozone generator 23 is controlled according to the flow rate of the gas substantially corresponding to the flow rate of the dilute ozone gas detected by a flow-meter 10 under a prescribed pressure condition. |
