Abstract

An air-conditioning unit of a vehicle for air-conditioning a vehicle interior may include a unit outlet for discharging air into the vehicle interior, an outside-air duct for an intake of outside air, and an air recirculation duct for recirculation of inside air from the vehicle interior. The air-conditioning unit may also include an outside-air shut-off element arranged in the outside-air duct, which in a closed position blocks a flow of outside air through the outside-air duct, and a recirculated-air shut-off element arranged in the air recirculation duct, which in a closed position blocks a flow of inside air through the air recirculation duct. The air-conditioning unit may further include a sensor device for detecting a property of air. On at least one duct of the outside-air duct and the recirculation duct, a bypass may be arranged which bypasses an associated shut-off element and is fluidically connected to the sensor device.
