Abstract: A motor vehicle air-conditioning device that includes an air inlet channel, an air-conditioning system, an air extraction channel, and a rotary heat exchanger. The air inlet channel has a supply air inlet opening operable to facilitate flow of vehicle exterior air into the air inlet channel. The air-conditioning system has an air supply channel fluidically connected to the air inlet channel. The air extraction channel has a discharge air inlet opening operable to facilitate flow of the vehicle interior air into the air extraction channel and a discharge air outlet opening operable to facilitate discharge of the extracted interior air through the air extraction channel and the discharge air outlet opening. The rotary heat exchanger is operable to, in an operating state thereof, provide a heat exchange between the air inlet channel and the air extraction channel.
