Air duct system

An air duct system for conducting air within a component of an air conditioning system of a motor vehicle, comprising:

• component housing including (i) a first housing part with a first connecting surface and (ii) a second housing part with a second connecting surface complimentary to the first connecting surface;
• the first connecting surface and the second connecting surface lying on one another and forming at least one air passage therebetween;
• a sensor through which air is flowable, the sensor connected to the at least one air passage in an air-conducting manner;
• the first housing part and the second housing part connected to each other with the first connecting surface and the second connecting surface abutting one another;
• wherein at least a portion of the at least one air passage is defined by and between the first connecting surface and second connecting surface;
• and
• wherein, at at least one constriction point, the at least one air passage has a reduced cross-section that is smaller than a cross-section of the at least one air passage outside of the at least one constriction point.

An air duct system for conducting air within an HVAC equipment of a motor vehicle, comprising:

• a housing of the HVAC equipment;
• a sensor through which air is flowable;
• the housing including at least two housing parts each with a connecting surface, the at least two housing parts including (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 abutting one another and fixedly connected to each other via the first connecting surface and the second connecting surface;
• an air duct through which air is flowable, the air duct defined by and between the first connecting surface and second connecting surface;
• the air duct connected to the sensor in an air-conducting manner;
• wherein the air duct has a constriction point at which a cross-section of the at least one air duct is reduced;
• and
• wherein the air duct is one of i) an inflow air duct for conducting an inflow of air to the sensor such that the constriction point is disposed upstream of the sensor and ii) an outflow air duct for conducting an out-flow of air from the sensor such that the constriction point is disposed downstream of the sensor.
