An HVAC unit for a motor vehicle is disclosed. The HVAC unit includes a housing, a sensor device through which air is flowable and an air duct arrangement through which air is flowable. The sensor device is attached to the housing and airflow-connected to the air duct arrangement at an interface. The interface is provided by two connecting pieces of the sensor device aligned in a Z-direction and two receptacles of the air duct arrangement corresponding with the two connecting pieces. The two connecting pieces are disposed on the sensor device and the two receptacles of the air duct arrangement are disposed in the housing. The respective connecting piece engages in the respective receptacle at the interface and is airtight-connected to the respective receptacle.

HVAC unit

An air duct system for conducting air within an HVAC equipment of a motor vehicle may include a housing of the HVAC equipment, a sensor through which air is flowable, and at least one air duct connected to the sensor in an air-conducting manner. The housing may include (i) a first housing part with a first connecting surface and (ii) a second housing part with a second connecting surface. The first housing part and the second housing part may abut one another and may be fixedly connected to each other via the first and second connecting surface. The at least one air duct may be formed, at least in regions, between the first and second connecting surface. The at least one air duct may have at least one constriction point at which a cross-section of the at least one air duct is reduced.

Air duct system

A method for operating an air-conditioning system that carries out an air quality testing cycle is disclosed. The air quality testing cycle includes: Step A: testing if the current pollutant concentration is below a predetermined first pollutant limit value; Step B: in the event that it is determined in the Step A that the current pollutant concentration is below the first pollutant limit value, testing if the bypass device is completely open or if the current flow rate of the blower device corresponds to a current air volume demand of the air-conditioning system; Step D: in the event that it is determined in the Step B that the bypass device is not completely opened or that the current flow rate does not correspond to the current air volume demand, testing current pollutant concentration is below a predetermined second pollutant limit value that is smaller than the first pollutant limit value.

Air conditioning system and associated method of operation

The present invention relates to a fluid line system () for guiding fluid, in particular for a motor vehicle. The fluid line system () comprises a sensor device () for capturing sensor parameters and a housing (), which has two or more housing parts (). Each housing part () has a mounting surface area () for arranging a further housing part (). The housing () further has a groove arrangement (), which comprises at least one groove recess (), which is arranged on a mounting surface area (), wherein a groove recess () has a groove opening (), which opens out to the respective mounting surface area (). In any case, the groove opening () is closed by in a fluid-tight manner means of the mounting surface area () of at least one further housing part (). It is attained thereby that a fluid duct (), through which fluid can flow and through which fluid can be applied to the sensor device (), is limited between the respective groove recess () and the respective mounting surface area ().

Fluid line system for guiding fluid, in particular for a motor vehicle, and air conditioning device for a motor vehicle, in particular a HVAC device

An air-conditioning system of a motor vehicle to air-condition a vehicle interior may include a channel system through which air is flowable and an outside-air channel configured to let outside air into the channel system. The air-conditioning system may also include a system conveying device separating a suction area from a pressure area and a system filter device separating a raw area from a pure area. The system filter device may include a filter housing and a filter material. The air-conditioning system may additionally include a system outlet to let air into the vehicle interior and a sensor device, including a sensor housing, in which at least one analysis channel is arranged, through which air, a characteristic of which is measured, is flowable. The sensor device may also include at least one sensor inlet and at least one sensor outlet to let air in and out of the sensor device.
