STERILIZATION DISINFECTION APPARATUS AND METHOD

To provide a technology for sterilizing and disinfecting pathogens with low concentration ozone and without affecting the human body.SOLUTION: A pathogen sterilization disinfection apparatus using ozone comprises a temperature controller that controls the ambient temperature in a space to be sterilized and disinfected in the range from 17 to 28 degrees, a humidity controller that controls the ambient humidity in the space to be sterilized and disinfected in the range from 40% RH to 70% RH, and an ozone concentration controller that controls the ambient concentration of ozone in the space to be sterilized and disinfected in the range from 10 ppb to 60 ppb, wherein the ozone concentration controller controls the ambient concentration of ozone according to the ambient humidity.SELECTED DRAWING: Figure 7 【課題】オゾン濃度が低く、人体に影響を及ぼさない病原体殺菌消毒技術を提供することを課題とする。【解決手段】オゾンを用いた病原体の殺菌消毒装置であって、殺菌消毒対象空間の雰囲気温度を１７度から２８度の範囲に制御する温度制御装置と、殺菌消毒対象空間の雰囲気湿度を４０％ＲＨから７０％ＲＨの範囲に制御する湿度制御装置と、殺菌消毒対象空間のオゾンの雰囲気濃度を１０ｐｐｂから６０ｐｐｂの範囲に制御するオゾン濃度制御装置と、を備え、オゾン濃度制御装置は、雰囲気湿度に応じてオゾンの雰囲気濃度を制御する。【選択図】図７
