An air-conditioning system comprises a channel system, a system conveying device positioned in the channel system and configured to convey air in the channel system, a sensor device comprising at least one analysis channel and configured to measure a characteristic of air flowing through the at least one analysis channel, and a suction jet pump comprising a motive-fluid inlet, a suction inlet, and a pump outlet. The system conveying device separates a suction area of the channel system arranged upstream of the system conveying device from a pressure area of the channel system arranged downstream from the system conveying device, and the sensor device further comprises a sensor outlet configured to release air from the sensor device. The motive-fluid inlet is fluidically connected to the pressure area via a suction jet branch-off point within the channel system, and the suction inlet is fluidically connected to the sensor outlet.

Motor vehicle air-conditioning system

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.

Air-conditioning unit of a vehicle

An air-conditioning system of a motor vehicle may include a channel system configured to allow air to flow therethrough during operation and at least one heat exchanger positioned within the main channel and configured to air-condition air supplied to a motor vehicle interior of the motor vehicle. The channel system may include a main channel. The system may include a sensor device configured to measure an air characteristic of air to be analysed. The sensor device may include an analysis channel which the air to be analysed can flow through, a generation device configured to generate electromagnetic waves penetrating the analysis channel, a sensor temperature-control space separated from the analysis channel, and a temperature-control channel configured to apply air-conditioned air to the generation device to control a temperature of the generation device. The generation device is at least partially arranged in the sensor temperature-control space.

An air-conditioning system of a vehicle for air-conditioning a vehicle interior compartment may include a channel system which is flowed through by air and a sensor device for detecting at least one property of air. The sensor device may include at least one analysis channel through which air is flowable during operation, and a generating device configured to generate and emit electromagnetic waves. The sensor device may also include a diverting device configured to divert the electromagnetic waves emitted by the generating device at least partially into an interaction section of the at least one analysis channel, through which interaction section the diverted electromagnetic waves may pass and interact with air flowing through the at least one analysis channel. The sensor device may also include a detector which detects the diverted electromagnetic waves after the interaction with the air.
