A ventilation device may include first and second supply ducts, a mixing section having a mixing duct into which the first and second supply ducts may lead, the first and second supply ducts arranged in the mixing section adjacent one another in a transverse direction, and first and second guides in the mixing section each running in the transverse direction and being located opposite one another in a longitudinal direction running transversely to the transverse direction, each guide having two guide walls running in the transverse direction and located opposite one another in a height direction running transversely to the transverse direction and longitudinal direction, at least one of the guide walls sloping away from the other guide wall at a slope angle with respect to the longitudinal direction. A valve may have a plate body and may be adjustably guided with a first guide section running in the transverse direction in the first guide and with a second guide section running in the transverse direction in the second guide. An actuator may during operation adjust the valve in the transverse direction between a first position, in which the valve fluidically separates the second supply duct from the mixing duct and opens a fluidic connection between the first supply duct and the mixing duct, and a second position, in which the valve fluidically separates the first supply duct from the mixing duct and opens a fluidic connection between the second supply duct and the mixing duct, wherein the first guide section has a first thickness running in the height direction and which is smaller than a second thickness of the second guide section running in the height direction in such a manner that both guide sections are each in contact with both guide walls of the associated guide.

Ventilation device

An air-conditioning system for air-conditioning a vehicle interior is disclosed. The air-conditioning system includes a blower for generating an air flow, a heating device for heating the air flow, and a ducting system that divides the air flow downstream of the heating device over at least two part air flows and supplies the at least two part air flows via associated ducts to associated air outlets, through which the part air flows exit into the vehicle interior. The heating device includes at least two separate regions each with at least one electric heating element that is separately controllable via a control device. The at least two separate regions are each permanently assigned one of the associated ducts of the ducting system.

Air conditioning system

A housing for a ventilation, heating, and/or air conditioning system of a motor vehicle, wherein the housing is made of multiple parts and forms at least one air flow path in the interior and optionally has at least one heat exchanger, whereby the housing has first regions and has second regions, whereby the first regions have a greater strength than the second regions.

Housing for a ventilation, heating, and/or air conditioning system

An air-conditioning unit of a motor vehicle may include a fan, an evaporator, and a heat exchanger. The heat exchanger may be arranged downstream of the evaporator. The evaporator and heat exchanger may both be arranged in a housing. The air-conditioning unit may also include a first bypass channel bypassing the evaporator. The first bypass channel may be arranged centrally on a side of the evaporator. A width of the first bypass channel may be smaller than a width of the side of the evaporator on which the first bypass channel is arranged.
