  • Patent number: 12018859
    Abstract: An HVAC duct ozone generator includes at least two ozone generation plate stacks, where each plate stack includes at least two independently electrically addressable plate groupings, where a primary plate grouping includes fewer ozone generation plates than a secondary plate grouping. Thus, the generator includes at least four independent ozone generation control channels to energize the primary and secondary plate groupings of each of the at least two plate stacks. The number of plates in a plate grouping may optionally be altered to reduce the ozone generation capacity of the primary plate grouping in relation to the secondary plate grouping through the movement of insulators between the stacked ozone generation plates.

    Abstract: A method and device for conversion of water into hydrogen peroxide, wherein a corona discharge zone is generated between a rotating electrode formed as a hollow rotor of a centrifugal fan and a fixed electrode. The rotating electrode is rotated relative to an insulation layer of the fixed electrode, and high voltage AC power is applied to the fixed electrode while conveying vapor through the corona discharge zone. In one aspect, the novelty resides in using the rotating electrode for conversion of water to vapor. In another aspect, conductivity between the two electrodes induces electrolysis, which is used for high voltage AC transmission to the rotating electrode.
