A ventilation system for a vehicle having a cabin includes a segmented plenum comprising a plurality of sub-plenums that are disposed above the cabin, a perforated panel defining the ceiling of the cabin and having plurality of perforations for air communication of the plenum with the cabin, and ductwork including one or more upper main ducts, lower main ducts, vertical ducts, and seat return ducts. The ducts communicate with each other to convey air, descending from the segmented plenum through the perforated panel as a high volume, low turbulence blanket of air through the cabin, back to the segmented plenum. The ventilation system also includes an air processing unit (APU) in communication with the ductwork and operable to sterilize the air conveyed therein, and one or more fans for circulating the air in the ventilation system.

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.
