Abstract
An air purification system includes a linear electrode that generates electromagnetic resonance; an electric field probe that measures the electric field intensity; and a controller that controls power supplied to the linear electrode. The controller adjusts the frequency of the power supplied to the linear electrode and the position at which the power is supplied to the linear electrode, to maximize an output value of a signal indicating the electric field intensity. Feedback control is performed to make the amount of ozone always constant, by monitoring the amount of ozone generated and adjusting the amplitude modulation of the power supplied, so that ozone necessary for decomposing viruses is generated but harmful nitrogen oxides are not generated as a result of applying, to gas molecules contained in influent gas, an energy that is at least the dissociation energy of oxygen molecules and no greater than the dissociation energy of nitrogen molecules.
