Air purification device for vehicle

An air purification device for a vehicle, comprising:

• a sorption device provided with a sorbent that sorbs moisture and carbon dioxide in air at a purification temperature and releases the sorbed moisture and carbon dioxide at a first regeneration temperature higher than the purification temperature;
• an air intake duct having one end formed with at least a suction opening for sucking air in a vehicle cabin and another end connected to an inlet of the sorption device;
• a three-way valve having an input port connected to an outlet of the sorption device;
• an air supply duct having one end connected to a first output port of the three-way valve and another end formed with a blowing opening for blowing air into the vehicle cabin;
• an exhaust duct having one end connected to a second output port of the three-way valve and another end formed with an exhaust opening for discharging air to outside of the vehicle cabin;
• a blower for sending air from the air intake duct into the sorption device;
• a heater for selectively heating air sent into the sorption device;
• and
• a controller configured to control the three-way valve, the blower, and the heater to thereby selectively execute a purification mode in which air in the vehicle cabin is sent into the sorption device at the purification temperature, and purified air from which moisture and carbon dioxide have been removed by the sorbent is blown into the vehicle cabin, and a first regeneration mode in which air heated to the first regeneration temperature is sent into the sorption device and exhaust air containing moisture and carbon dioxide released from the sorbent is discharged to the outside of the vehicle cabin.
