Vehicular air-conditioning apparatus having photocatalytic module

A vehicular air-conditioning apparatus having a photocatalytic module, comprising:

• a duct configured to allow conditioned air to flow therethrough;
• a photocatalytic filter mounted in the duct, wherein the photocatalytic filter is coated with a photocatalytic material configured to remove harmful substances in reaction to light energy;
• and
• a rotation unit rotatably mounted in the duct in a state of being spaced apart from the photocatalytic filter, the rotation unit being provided with at least one light source configured to radiate light toward the photocatalytic filter,
• wherein, when the rotation unit is rotated, a position of the at least one 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,
• wherein the rotation unit comprises:
• a fixed body extending across an interior of the duct and fixed to the interior of the duct;
• and
• a rotary body rotatably mounted to the fixed body and disposed at a center of the interior of the duct, the rotary body comprising at least one wing configured to be rotated by the conditioned air, and
• wherein the at least one light source is mounted on the at least one wing.
