Abstract
An air vent for thermally controlling the temperature in the cabin of a vehicle. The air vent includes an air mover and a plurality of thermal control channels. Each thermal control channel of the plurality of thermal control channels includes a magnetocaloric material. Further, the air vent includes a magnet for inducing a changing magnetic field in the magnetocaloric material, as well as a vent damper downstream of the plurality of thermal control channels. The vent damper is configured to selectively direct airflow from the air mover and divert air from at least one thermal control channel to a vent space and air from at least one other thermal control channel to a regulated temperature space.
