A blower case for a heating, ventilation, and air conditioning (HVAC) system. The blower case includes an inlet for airflow entering the blower case. Also included is a dehumidifier, which is movable between a first position and a second position. In the first position the dehumidifier is in a path of airflow entering the blower case through the inlet. In the second position the dehumidifier is not in the path of airflow entering the blower case through the inlet.

The present invention relates to a blower unit of an air conditioner for a vehicle, which can effectively prevent water from being introduced into a motor and has a motor housing and a blower wheel improved to smoothly perform cooling of the motor. The blower unit of a two-layered air conditioner for a vehicle, which can divide and inhale indoor air and outdoor air, includes: a scroll case having an upper passageway and a lower passageway; a first blower wheel disposed in the upper passageway; a second blower wheel disposed in the lower passageway and arranged below the first blower wheel; a blower motor for rotating the first blower wheel and the second blower wheel; and a motor housing for covering the blower motor, wherein a hub for guiding air is disposed on the second blower wheel, and the hub of the second blower wheel is partially overlapped with an end portion of the motor housing.

An air flow device for an instrument panel which blows an air from the instrument panel at a front of a vehicle compartment of an automobile to make the air flow to the vehicle compartment, includes a blower, a blower outlet on the instrument panel, from which an air sent from the blower to which the blower outlet is coupled is blown to the vehicle compartment, and a blower inlet on the instrument panel for the blower outlet, into which the air blown from the blower outlet is drawn. The blower outlet is installed so as to open to the blower inlet along a surface of the instrument panel while the blower inlet is installed so as to open to the blower outlet along the surface of the instrument panel.

A system for controlling inside/outside air in air conditioner may include an air conditioner including an upward discharge passage, through which air is discharged toward a front glass of a vehicle, a downward discharge passage, through which air is discharged toward a floor of the vehicle, the upward discharge passage and the downward discharge passage being separated from each other, a first intake door, an opening amount of which is determined according to a ratio between inside air and outside air introduced into the upward discharge passage, and a second intake door, an opening amount of which is determined according to a ratio between inside air and outside air introduced into the downward discharge passage; and a control unit configured of controlling the opening amounts of the first and second intake doors according to a heating load of the air conditioner and a humidity of the interior of the vehicle.

An air supply unit, in particular for a heating, ventilation or air-conditioning unit in particular of a motor vehicle, an includes at least one air inlet, an air filter unit and a blower unit and an air outlet, wherein the filter unit comprises a filter housing in which a filter support is provided to support a filter element, which is located within the filter housing and which is supported within the filter housing by the filter support, wherein the filter support comprises an air guide for guiding air.

In an air conditioning case, a blower sucks air flowing out from first and second upstream side ventilation paths from one side in an axial direction of a fan axis by rotation of a blower fan and allows the sucked air to flow to first and second downstream side ventilation paths. An upstream side guide member is provided on one side in the axial direction with respect to the blower fan and guides the air to the blower fan. Further, the upstream side guide member has a twisted shape and guides the air to the blower fan along the twisted shape.

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.

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.

The present invention relates to a two-layered blower unit of an air conditioner for a vehicle, which includes a means for smoothly guiding axially flowing air to flow in a radial direction and has optimized structure and arrangement for fixing the guide means.

A vehicle climate control system includes an air scoop, a vertical duct, and an airfoil. The air scoop is disposed along a bottom surface of a vehicle floor panel. The vertical air duct extends upward from the air scoop and is configured direct air from the scoop toward a heat exchanger. The airfoil is disposed within the air scoop and is arranged to direct air entering the air scoop upwards and into the vertical air duct.
