Abstract
An air purification device for a vehicle includes: a sorption device provided with a sorbent; an air intake duct for sucking air in a vehicle cabin; an outlet-side three-way valve connected to the sorption device; an air supply duct for blowing air into the cabin; an exhaust duct for discharging air to outside of the cabin; a blower; a heater; and a controller. The controller selectively executes a purification mode in which air in the cabin is sent into the sorption device at a purification temperature, and purified air from which moisture and carbon dioxide have been removed by the sorbent is blown into the cabin, and a first regeneration mode in which air heated to a 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 cabin.
