Air purification apparatus for vehicle

An air purification apparatus for a vehicle comprising:

• a plurality of adsorption units configured to adsorb carbon dioxide and water vapor in air;
• a purification passage configured to introduce air from a passenger compartment into a first adsorption unit, of the plurality of adsorption units, and to return air, from which carbon dioxide and water vapor have been adsorbed and removed by the first adsorption unit, to the passenger compartment;
• and
• a regeneration passage configured to introduce air for regeneration into a second adsorption unit, of the plurality of adsorption units, and to discharge used air for regeneration obtained by regenerating the second adsorption unit outside of the vehicle,
• wherein an upstream side of the regeneration passage and an upstream side the purification passage, upstream from the plurality of adsorption units, are constituted by an internal air introduction pipeline configured to introduce air from the passenger compartment into the plurality of adsorption units,
• wherein the internal air introduction pipeline branches into a plurality of parts that are connected to the plurality of adsorption units,
• wherein an upstream side of the plurality of adsorption units are partitioned into two branch-off passages by a partition wall, and
• wherein a cold/heat supply apparatus configured to heat air in a first branch-off passage on one side and cool air in a second branch-off passage on the other side is installed on the partition wall.

• wherein a return pipeline that constitutes a part of the purification passage and a vehicle-outside discharge pipeline that constitutes a part of the regeneration passage are selectively connected to a downstream side of each of the plurality of adsorption units by a flow path switching mechanism configured to selectively connect the downstream side of each of the plurality of adsorption units to any one of the return pipeline and the vehicle-outside discharge pipeline.
