摘要： An ozone generator (100) includes: a flow path (1) through which gas flows from an inlet (5) to an outlet (6); an ozone generation unit (3) disposed in the flow path (1); and an ozone sensor (4) disposed in the flow path (1) and upstream of the ozone generation unit (3). The flow path (1) has an upstream-side flow path (130) that forms a gas passing space (AR) located upstream of the ozone generation unit (3) and through which the gas flows from one side to another side in a predetermined direction. The inlet (5) is disposed closer to an outer circumferential portion (131) of the upstream-side flow path (130) than the ozone sensor (4).

摘要： Discharge device (10) includes discharge electrode (41), voltage application circuit (2), and current limiting element (43). Discharge electrode (41) is disposed to face counter electrode (42), and retains liquid (50). Voltage application circuit (2) is electrically connected to discharge electrode (41) and counter electrode (42) with discharge electrode (41) as a ground side. Voltage application circuit (2) generates discharge between discharge electrode (41) and counter electrode (42) by applying a voltage between discharge electrode (41) and counter electrode (42). Current limiting element (43) is electrically connected to a side of discharge electrode (41) opposite to counter electrode (42). Current limiting element (43) limits a current flowing to discharge electrode (41).

摘要： Provided is an air cleaning system (1) including: an ozone generation unit (40) that generates ozone gas; and a discharge unit (50) that atomizes or vaporizes an aqueous alcohol solution and discharges the aqueous alcohol solution. A mole fraction of an alcohol included in the aqueous alcohol solution with respect to the aqueous alcohol solution is 0.05 or more and 0.35 or less. A hydroxyl radical is generated through a reaction of the ozone gas with the aqueous alcohol solution that has been atomized or vaporized.

摘要： A decontamination method is a decontamination method for decontaminating the inside of a decontamination target by removing at least one of microorganisms and viruses present in the decontamination target. This decontamination method includes a step of releasing vapor containing peracetic acid into the decontamination target, without releasing mist containing peracetic acid. An average humidity inside the decontamination target during decontamination is RH82% or more. A peracetic acid vapor load that is a value obtained by adding a concentration of peracetic acid in the vapor every minute from a start of decontamination to a completion of decontamination is 2000 ppm or more.

摘要： An air sterilizer (1000) capable of increasing the generation efficiency of hydroxyl radicals is disclosed. The air sterilizer (1000) includes a housing (1100), a container (BO), a blowing fan (1200), an ozone generator (1300) and a mixing fan (1400). In the housing (1100), a first air path (AP1) connecting a first air inlet (AI1) and a mixing space (MS), a second air path (AP2) connecting a second air inlet (AI2) and the mixing space (MS), and a third air path (AP3) connecting the mixing space (MS) and an air outlet (AO) are formed. The container (BO) is disposed inside the housing (1100) to hold a liquid (LQ). An inlet (B) of the container (BO) is in contact with the first air path (AP1). The blowing fan (1200) is disposed in the second air path (AP2). The blowing fan (1200) enforces air to flow from the second air inlet (AI2) to the mixing space (MS). The ozone generator (1300) is disposed in the second air path (AP2) to generate ozone using air introduced through the second air inlet (AI2). The mixing fan (1400) is disposed in the mixing space (MS). The mixing fan (1400) mixes air containing evaporated liquid (LQ) in the container (BO) and flowing through the first air path (AP1) to arrive at the mixing space (MS) and air containing ozone and flowing through the second air path (AP2) to arrive at the mixing space (MS).
