A disinfection device, a vehicle, and a construction machine capable of preventing infection of infectious diseases are described. The disinfection device includes a fluid supply device that supplies a fluid to a disinfection area and an irradiation device that irradiates the disinfection area with invisible light.

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.

The invention relates to a heating, ventilation and/or air-conditioning device (1) for a motor vehicle, characterised in that it comprises at least one first air circulation channel (3), at least one second air circulation channel (4), and means (5, 6) for generating an air stream in the first air circulation channel (3) and/or in the second air circulation cannel (4), the device (1) also comprising means for the inflow of a cleaning product (13, 16) ending in the first air circulation channel (3) and/or in the second air circulation channel (4).
