An air conditioning unit for a vehicle includes a first channel and a second channel, a blowing unit including a first blower fan and a second blower fan that rotate together by sharing a rotary shaft and a driving unit, a bypass channel, and a control door disposed among the outlets of the first channel and the second channel, the heating core, and the bypass channel to control air discharged from the first channel or the second channel to pass through the heating core or not to pass through the heating core through the bypass channel.

Disclosed is an air vent comprising a housing configured to guide an air flow from an air inlet to an air outlet, an air guide arranged at least partly within the housing such that the air guide and the housing define a first air channel and a second air channel, a regulating flap arranged between the air inlet and the air guide, configured to regulate a ratio between a first partial air flow through the first air channel and a second partial air flow through the second air channel, a first and second shutoff element arranged at least partly within the housing. The first shutoff element is configured to shut off the first partial air flow without shutting off the second partial air flow and the second shutoff element is configured to shut off the second partial air flow without shutting off the first partial airflow.

Disclosed herein is a vehicle air vent that includes a duct having a channel therein through which air flows, and a discharge end through which the air is discharged, a first adjuster installed in the duct so as to be rotatable about a first rotary shaft, an extending direction of a first opening being varied depending on the angle of rotation of the first adjuster, a second adjuster installed in the duct so as to be rotatable about a second rotary shaft, an extending direction of a second opening being varied depending on the angle of rotation of the second adjuster, a third adjuster installed on the discharge end so as to be rotatable about a third rotary shaft, a third opening being defined between the third adjuster and the duct, and an interlocking connector operatively connecting the first adjuster to the third adjuster.

Disclosed is an air conditioning apparatus for a vehicle, the air conditioning apparatus including: an air conditioning duct forming a passage for conditioned air, and provided with an outlet on a wall surface thereof for directing conditioned air. A door is provided inside the air conditioning duct, with a rotation shaft being provided on a wall surface opposite to the wall surface of the air conditioning duct. The door opens and closes the air conditioning duct by a rotation thereof. A partition wall protrudes from a surface of the door along the wall surface of the air conditioning duct. The partition wall opens and closes the outlet in response to the rotation of the door.

Disclosed is an HVAC system configured to reduce noise. The HVAC system includes a door having a first and second end. The door includes an elastomer along the first end and a rotatable member adjacent the second end. The elastomer includes a door touch area. The case defines an internal case portion, external case portion, and a case opening fluidly connecting the internal and external case portion. The case is configured to receive the rotatable member of the door such that the door is rotatable about an axis between a first position, where the door covers the case opening, and a second position, where the door does not cover the case opening. The case includes a case touch area with a graining. The door touch area and the case touch area are substantially parallel and in contact along a surface contact area when the door is in the first position.

An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a recirculation inlet in fluid communication with a passenger compartment of the vehicle and a fresh air inlet in fluid communication with an ambient environment. An air distribution door is disposed in the inlet section for controlling a distribution of air entering the inlet section through the recirculation inlet and the fresh air inlet. A baffle door is disposed in the inlet section for selectively reducing a flow area through the fresh air inlet to accommodate a ram air pressure induced by motion of the vehicle relative to fresh air of the ambient environment.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle. The HVAC system includes an HVAC case. The HVAC case has a first inlet and a second inlet. The first inlet is in receipt of airflow from a front blower. The second inlet is in receipt of airflow from a rear blower. A front foot outlet directs airflow towards the feet of occupants at a front of the vehicle. A rear foot outlet directs airflow from the rear blower towards a rear of the vehicle. A rear-to-front airflow control door is movable to direct airflow generated by the rear blower and heated by a heater core through the rear foot outlet, through the front foot outlet, or simultaneously through both the rear foot outlet and the front foot outlet.

A heating, ventilation, and air conditioning (HVAC) system including an HVAC assembly, a set of pins, mode doors, a mode plate, an actuator, and an HVAC control module. The mode doors control airflow from the HVAC assembly. A position of each mode door is controlled by a corresponding pin of the set of pins. The mode plate includes (i) a set of grooves, (ii) a first adjustment path and (iii) a second adjustment path. The first adjustment path causes a first pin of the set of pins to move toward a center. The second adjustment path causes the first pin to move away from the center of the mode plate. An HVAC module selectively actuates the actuator to causes the mode plate to rotate in at least one of a passive direction and the active direction in response to receiving a mode request.

A motor vehicle air conditioning unit, having a housing with at least one air channel arranged therein and with at least one heat exchanger for conditioning the air in the at least one air channel, the housing having at least one first air outlet and one second air outlet, a first air outlet channel being assigned to the first air outlet and conducting air to the first air outlet, and a second air outlet channel being assigned to the second air outlet and conducting air to the second air outlet, a first vane valve and a second vane valve being provided. The first vane valve assigned to the first air outlet channel, and the second vane valve assigned to the second air outlet channel, the first vane valve and the second vane valve being rotatably fixedly connected to a shaft and being rotatable by an actuator driving the shaft.

A vehicle cabin air register includes a tube shaped retainer disposed in a register opening, a bezel connected to the retainer, and a first fin axially supported by a pivot axis at an inner side of the retainer. A restricting mechanism restricts a pivot range of the first fin. The vehicle cabin air register also includes a second fin including a pair of second fin main bodies, an operation knob attached to a center portion of the first fin, a first flow path, and a second flow path. A minimum gap of the first flow path is narrower than a minimum gap of the second flow path. When the register is in a restricted state, the downstream end of the operation knob and the downstream end of the other second fin main body of the pair of second fin main bodies are positioned downstream of the bezel.
