Abstract

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.
