Air-conditioning device for a motor vehicle, in particular for a car, and motor vehicle
An air-conditioning device includes a first circuit and a second circuit. Air supplied to an interior chamber of a motor vehicle flows through an air pathway. A first heat exchanger is disposed in the air pathway where the air flowing through the air pathway is heatable by the first heat exchanger. A second heat exchanger is disposed downstream of the first heat exchanger where the air flowing through the air pathway is heatable by the second heat exchanger. A valve device has a first switching state in which the first heat exchanger is disposed in the first circuit and the second heat exchanger is disposed in the second circuit and a second switching state in which the first heat exchanger is disposed in the second circuit and the second heat exchanger is disposed in the first circuit.
