摘要： 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.

摘要： A humidifier includes a housing, a water reservoir configured to hold a quantity of water, a fan assembly configured to generate an air flow path within the humidifier, a sanitizing system, and a wick assembly. The sanitizing system is configured to generate a sanitizing gas and to transfer the sanitizing gas to the water reservoir such that at least a portion of the sanitizing gas is absorbed into the water in the water reservoir. The wick assembly is fluidly configured to receive water from the water reservoir and transfer the water into the air flow path to generate humidified air. The water received by the wick assembly includes at least a portion of the sanitizing gas absorbed into the water, wherein at least a portion of the water received by wick assembly flows back to the water reservoir.

摘要： An air purifier and a purification booth for preventing infections that can effectively suppress ozone generation while sanitizing the air using relatively short-wavelength ultraviolet light. The air purifier includes: a housing in which a reflux chamber is formed between an intake opening and an exhaust opening; an ultraviolet lamp that simultaneously generates ultraviolet rays with a wavelength of 185 nm and ultraviolet rays with a wavelength of 254 nm inside the reflux chamber; a manganese dioxide-based catalytic filter through which air passes while proceeding from the reflux chamber toward the exhaust opening; and a reflux plate which is disposed inside the reflux chamber and which is hit by a portion of the air flowing from the intake opening toward the exhaust opening, thereby causing the portion of air to reflux, wherein the ultraviolet rays emitted by the ultraviolet lamp irradiate both the air proceeding from the intake opening to the reflux plate and the portion of air flowing back from the reflux plate.

摘要： A cover assembly is configured for disinfecting an air conditioning unit. The assembly includes a cover made of a pliable material that is shaped to be installed on the inside portion of an air conditioning unit. The assembly also includes an ozone generator configured to direct ozone into the air conditioning unit. A controller is operatively coupled to the ozone generator and is configured to control operation of the ozone generator.
