  • Vehicular air-conditioning apparatus having photocatalytic module
    Patent number: 11958341
    Abstract: A vehicular air-conditioning apparatus includes a photocatalytic module in which light is radiated on a photocatalytic filter to sterilize the photocatalytic filter. In particular, vehicular air-conditioning apparatus incudes: a duct to allow conditioned air to flow therethrough; the photocatalytic filter mounted in the duct and coated with a photocatalytic material to remove harmful substances in reaction to light energy; and a rotation unit rotatably mounted in the duct. In particular, the rotation unit is provided with a light source to radiate light toward the photocatalytic filter. When the rotation unit is rotated, a position of the light source is changed in a rotational direction of the rotation unit such that the light is radiated on the photocatalytic filter over an increased range. Thus, a filter sterilization effect is improved over the entire area of the photocatalytic filter with reduced number of light sources.
