Sensor assembly useful in ventilation system of vehicle air-conditioner comprises housing having first and second measurement chambers that are gas-tightly separated in the housing, and electronic processor for evaluating all sensor data

摘要

The sensor assembly (10) of a ventilation system of a vehicle air-conditioner comprises a housing (14), in which a first measurement chamber (18) is provided with a carbon monoxide sensor and/or a nitrogen oxide sensor and a second measurement chamber (28) is provided with a carbon dioxide sensor, and an electronic processor for evaluating all sensor data. The first and second measurement chambers are gas-tightly separated in the housing. An air humidification sensor and a temperature sensor are provided in the first and/or second measurement chambers. The sensor assembly (10) of a ventilation system of a vehicle air-conditioner comprises a housing (14), in which a first measurement chamber (18) is provided with a carbon monoxide sensor and/or a nitrogen oxide sensor and a second measurement chamber (28) is provided with a carbon dioxide sensor, and an electronic processor for evaluating all sensor data. The first and second measurement chambers are gas-tightly separated in the housing. An air humidification sensor and a temperature sensor are provided in the first and/or second measurement chambers. A gas sensor is provided in the first measurement chamber for detecting odorous substances perceptible from human. A third chamber is provided between the first and second chambers and is gas-tightly separated from the both measurement chambers. The sensor assembly has a common electrical connecting point. The first and second measurement chambers have gas entrance openings (16), which are arranged at opposite sides of the housing and flow into the associated measurement chambers. Independent claims are included for: (1) a ventilation system for a vehicle air-conditioner; and (2) a method for controlling a ventilation system for a vehicle air-conditioner.
