A vehicle air-handling system includes a heat exchanger, a blower in communication with the heat exchanger, and an operable duct having driver and passenger portions that are each in communication with the heat exchanger and the blower. When the blower is activated, the driver portion continuously delivers blower air and the passenger portion selectively delivers blower air.

A vehicle HVAC system may include a housing, a blower disposed in the housing to blow air, an evaporator core disposed in the housing to cool the air having passed through the blower, a heater core disposed in the housing to increase a temperature of the air having passed through the evaporator core, a temperature door assembly including a pair of slidable temperature door plates to control the air having passed through the blower, and a mode door assembly including a slidable mode door plate to control a vent outlet and a floor outlet such that one thereof is closed, or to control air to be discharged through the vent outlet and the floor outlet.

A vehicle HVAC system including a ram air throttling assembly. The ram air throttling assembly includes: a housing defining a ram air inlet, a recirculation air inlet, and an outlet; a first door within the housing, the first door movable to direct airflow from at least one of the ram air inlet and the recirculation air inlet to the outlet; and a second door slidably movable to throttle airflow into the housing through the ram air inlet.

An air conditioner for a vehicle has a first shaft that drives a first air-mix door in conjunction with being rotated, a second shaft that drives a second air-mix door in conjunction with being rotated, and a rack that interlocks the first shaft and the second shaft with each other. The rack has an elongated shape, thereby a mounting space can be smaller with respect to a rink mechanism. Therefore, an air conditioning unit can be downsized.

The present teachings include a heating, ventilation, and air conditioning (HVAC) unit including an evaporator, a heater core, and an airflow control door. The heater core is arranged downstream of the evaporator with respect to a direction of airflow through the HVAC unit. The airflow control door is downstream of both the evaporator and the heater core. The airflow control door is movable to increase and decrease a cross-sectional area of an airflow path downstream of the temperature control door, such as to facilitate mixing of airflow that has passed through the heater core with airflow that has passed around the heater core.

A heating, ventilation, and air conditioning (HVAC) apparatus for an automotive vehicle may include an internal volume divided into upper and lower regions, and configured for blowing the air to a defrost vent and a front seat face vent is made through the upper region, and blowing the air to a front seat foot vent and a rear seat vent is made through the lower region.

In an air conditioning system for a mobility vehicle, air is introduced into a housing in multiple directions including forward, rearward, leftward, and rightward directions, such that outside air is introduced into a heat exchanger in the housing and heat exchange is performed regardless of a traveling direction of the mobility vehicle. In addition, the amount of outside air to be provided to an external heat exchanger is adjusted depending on the traveling direction of the mobility vehicle or whether a heat pump is used, which improves the efficiency in operating the external heat exchanger.

A vehicle air-conditioning device include an air conditioning case and a heating device. The air conditioning case is formed with a defroster opening and a side-face opening. A defroster door for opening and closing the defroster opening and a face door for opening and closing the side-face opening are provided inside the air conditioning case. The face door is a slide door that opens and closes the side-face opening by moving along an opening plane of the side-face opening. The air conditioning case has a structure in which air that has passed through the heating device is guided along an inner door surface of the face door to the defroster opening. A gap opening for communication between upstream and downstream of the face door in an air flow direction is formed. The gap opening has an opening plane along a moving direction of the face door.

An air blowing device of the present disclosure has a wall portion, a duct, a guide wall, and an airflow forming mechanism. The wall portion is provided with an opening periphery providing a blow outlet. The duct communicates with the blow outlet. The guide wall is provided in an inner wall of a downstream portion of the duct and has a wall surface having a shape protruding toward an inside of the duct. The airflow forming mechanism forms a flow of air along the guide wall such that the air flowing through the duct is blown out of the blow outlet while being bent along the guide wall. The opening periphery has a portion that communicates with a downstream side of the guide wall and that has a shape protruding in a blowing direction of the air, which is bent along the guide wall from the blow outlet.

A vehicle air conditioner includes an evaporator configured to cool air, a heater core provided on a downstream side of the evaporator, a plurality of doors provided between the evaporator and the heater core, and a central air path formed on the downstream side of the evaporator. The central air path is provided with a first door of the plurality of doors, and a first side air path formed on a first side of the central air path. The central air path is further provided with a second door of the plurality of doors, a second side air path formed on a second side of the central air path, and a third door of the plurality of doors. A sub-casing is configured to form the central air path, and a first division casing and a second division casing are configured to sandwich the sub-casing.
