The photoreactor has UV-C LEDs that emit UV-C radiation. The control device controls the air passing through the photoreactor using the controllable valves arranged in the photoreactor line section in such a way that the air passing through is exposed to a predetermined UV-C radiation dose.

An electrification apparatus for an electrostatic dust collector, including: a first electrode part having a shape of a plate having a plurality of through holes formed thereon in such a manner as to apply one of positive and negative electrodes thereto; and a second electrode part having protrusions each having a plurality of fine conductive fibers in such a manner as to protrude outwardly from the through holes of the first electrode part, whereby electrification performance is improved and harmful ozone and electromagnetic waves are reduced.

An air treatment system may create an air flow pattern in a vehicle interior space, using air discharges in multiple directions and louvers such that some vanes within a louver are not parallel to other vanes within the louver. An air treatment system may provide bulk air flow to the vehicle interior and directed airflow to a driver region. An air flow system may comprise, internally, a constriction bounded by an edge of a UV light shield and an edge of a filter housing. Such air treatment systems, using filtration and UV light, effectively remove or kill viruses and other pathogens, for use in buses and similar vehicles.

The present invention relates to a photocatalytic module for an automobile air conditioner and an automobile air conditioner having the same and, more particularly, to a photocatalytic module capable of eliminating various germs resulting from dew formed on an evaporator installed in an automobile air conditioner and corresponding bad smell, and an air conditioner having the same.

The photocatalytic module includes a duct fixation frame 54 adjacent to an inner wall of the duct 10; a filter fixation frame 55 having one end connected to the duct fixation frame, the filter fixation frame 55 fixing the photocatalytic filter 52; a photocatalytic filter 52 fixed by the fixation frame 55, being formed by applying a photocatalytic material onto a supporter having a shape of a plurality of cells neighboring each other and provided with a plurality of airflow paths; and a substrate 58 fixed to the duct fixation frame 54 and equipped with an ultraviolet (UV) light emitting diode (LED) 59 for radiating ultraviolet light toward the photocatalytic filter 52.

The present provides an air conditioner having the photocatalytic module installed therein and an LED disposed upstream of the photocatalytic filter on the flow path of the duct.

A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e., hydroponic greenhouses, aircraft, rail and road vehicles, in building ducts, or rooms, includes mounting an atmospheric hydroxyl radical generator along an inside surface of an occupied space having respective air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics medical grade pure quartz, which emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.

A device and method for purifying a vehicle cabin is provided. The device comprises a housing, a plurality of light emitting diode (LED) modules each containing an LED, wherein the LED modules are positioned at least partially within the housing, a catalytic target structure, wherein the structure is located below at least one of the LED modules in the plurality of LED modules, a plurality of reflectors, wherein the reflectors are located below at least one of the LED modules in the plurality of LED modules, a plurality of fans, wherein the fans are located at least partially within the housing, a plurality of photocatalyst filters positioned at least partially within the housing, wherein at least one of the plurality of photocatalyst filters is in parallel with at least one of the LED modules in the plurality of LED modules, and a control unit located at least partially within the housing, wherein the control unit is operatively connected to the plurality of LED modules.
