The airflow control door is configured to control airflow through each one of the defrost outlet, the primary demist outlet, and the secondary demist outlet.

A climate control system includes a fluid delivery module. The fluid delivery module includes a housing defining a fluid flow path between an inlet and an outlet with the outlet having an elongated, slit-like shape and is not visible within a sight line of a user. The fluid delivery module further includes a fluidic control device disposed within the housing between the inlet and the outlet and movable to vary a direction of the fluid flow path within the housing.

A HVAC system for a motor vehicle having a housing, wherein the housing has an air inlet for admitting air and a cold air path in which cold air flows is provided in the housing and a warm air path in which warm air flows is provided in the housing, wherein the warm air path and the cold air path open into a mixing chamber, wherein a mixing flap is provided for controlling the proportion of cold air flowing into the mixing chamber and the proportion of warm air flowing into the mixing chamber, wherein the mixing flap is arranged rotatable about an axis and is driven by a flap actuator which has a drive shaft, wherein a gear with a nonlinear translation characteristic is provided between the mixing flap and the drive shaft.

The present invention relates to an air conditioner for a vehicle having a rear seat outlet, which can relieve temperature inversion that discharge temperature of the console vent becomes higher than discharge temperature of a rear seat floor vent in a bi-level mode, and prevent reduction of air volume of the console vent in the cooling mode. The air conditioner for a vehicle, which has a rear seat outlet, includes an air-conditioning case having an air passageway formed therein and a plurality of air outlets, and a cooling heat exchanger and a heating heat exchanger disposed in the air passageway of the air-conditioning case to exchange heat with air passing through the air passageway, wherein the air outlets include a console vent and a rear seat floor vent, and an entrance of the rear seat floor vent is formed above an entrance of the console vent.

A heating and air conditioning system for a motor vehicle including a housing having an air outlet, a heating heat exchanger disposed inside the housing with a warm air path to heat air flowing therethrough, a warm air duct having a warm air intake opening and a warm air duct discharge opening disposed downstream of the heating heat exchanger channeling a partial flow of warm air from the warm air path to the air outlet, and a mode control damper rotatable about a rotational axis and connected downstream of the warm air duct in terms of flow, wherein the air outlet may be selectively opened completely or partially, and in a closed state may be partially or completely closed. The mode control damper functions simultaneously as the control damper for controlling the volume of air exiting the warm air duct discharge opening.

A vehicle heating, ventilation, and air conditioning (HVAC) unit. The vehicle HVAC unit includes an evaporator, a driver side face outlet, and a passenger side face outlet. A face airflow control door extends across both the driver side face outlet and the passenger side face outlet. A divider separates a driver side airflow path from a passenger side airflow path. The driver side airflow path extends across the evaporator to the driver side face outlet, and the passenger side airflow path extends across the evaporator to the passenger side face outlet. A passenger side airflow control door is within the passenger side airflow path between the face airflow control door and the evaporator. The passenger side airflow control door is movable to block airflow through the passenger side airflow path to the passenger side face outlet.

A zone assembly for a vehicle includes a housing and a generally cylindrical mode door. The housing includes a cavity, an inlet channel, a first vent channel, and a second vent channel. Each of the channels is fluidly coupled to the cavity. The mode door includes a plurality of louvers and a plurality of extension pieces extending therefrom. The mode door is located in the cavity. The mode door is rotatable between an open position in which fluid may flow from the inlet channel through the mode door to one of the first vent channel or the second vent channel, and a closed position in which the mode door restricts fluid from flowing from the inlet to both the first vent channel and the second vent channel.

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.

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.

An air ventilation device of a vehicle includes: a housing including an air inlet and an air outlet and a cooling core and a heating core disposed between the air inlet and the air outlet; a rear extending flow path extending to the rear of the vehicle, and having a first end connected to the air outlet of the housing and a second end connected to a back seat air vent disposed to face a back seat space; an air collecting flow path directly connecting the rear extending flow path and the air inlet of the housing; and an opening and closing door structure opening and closing air circulation between the rear extending flow path and the air outlet and air circulation between the air collecting flow path and the air inlet.
