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

An air filter for a ventilation system of a motor vehicle may include a plate-shaped filter body of a folded filter material and at least one sealing strip secured to a lateral edge of the filter body. Adjacent folds of the filter body may be connected to one another via a seam, may follow one another in a longitudinal filter direction, and may extend in a transverse filter direction. The at least one sealing strip may have at least one removal opening penetrating the at least one sealing strip. At least one removal nozzle for removing air flowing through the air filter may be securable to the at least one removal opening.

Air filter and ventilation system comprising the air filter

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 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.

Air-conditioning system of a motor 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.

Air-conditioning system for a vehicle

A multi-layer filter material for an interior air filter element of an air conditioning system of a vehicle may include an active layer having a plurality of non-impregnated activated carbon particles, an impregnation layer having a plurality of impregnated activated carbon particles, and an ion exchange layer having a plurality of ion exchanger particles. The active layer may be arranged between the ion exchange layer and the impregnation layer. The active layer may further include a first ash content and the impregnation layer may further include a second ash content. The first ash content in the active layer may be less than the second ash content in the impregnation layer.
