An HVAC system including a defrost manifold. The defrost manifold has a first side window outlet, a second side window outlet, and a windshield outlet. A first rib partially obstructs the first side window outlet. A second rib partially obstructs the second side window outlet. A control door is movable to open and close the defrost manifold. A first wall extends from a first portion of the control door that is opposite to the first side window outlet. A second wall extends from a second portion of the control door that is opposite to the second side window outlet. Movement of the control door varies the position of the first wall relative to the first rib, and varies the position of the second wall relative to the second rib, to control airflow through the first and second side window outlets.

An air-handling device for influencing an air stream into an interior of a vehicle includes an air duct having a duct entrance for inflow of the air stream and two component air ducts, each respective component air duct including a respective component duct exit for outlet of a respective component air stream in a respective component outlet direction. The two component air ducts have different component outlet directions. The air-handling device further includes a flow director mounted between the component air ducts and the air duct, the flow director configured to be movable between at least two variation positions for varying fractions of the air flow into the respective component air streams. The air-handling device additionally includes a flow adjustor configured to be movable between at least two adjustment positions.

A defrost airflow door assembly for a vehicle heating, ventilation, and air conditioning (HVAC) assembly. The defrost airflow door assembly includes a main defrost door defining a defrost bleed opening. The main defrost door is movable to control airflow through a windscreen defrost outlet of the HVAC assembly. A side defrost door is movable to control airflow through both the defrost bleed opening and a side window defrost outlet of the HVAC assembly.

Described herein is air distributing device for an air conditioning unit of a motor vehicle, the device including: a housing defining an air intake chamber, on the housing there being formed an air inlet, a central air outlet, and two side air outlets. The device also includes a drum flap mounted rotatably about an axis (z) orthogonal to a direction that goes from the air inlet to the central air outlet. The flap is movable between a first position, wherein the air inlet is closed by the flap; a second position, wherein the two side air outlets are closed by the flap and an air flow between the air inlet and the central air outlet is allowed; and a third position, wherein the central air outlet is closed by the flap and an air flow between the air inlet and the side air outlets is allowed.

An air flow control for a ventilation, heating, or air conditioning unit of a motor vehicle, having a housing with a cold air passage with a first inlet opening and with a hot air passage with a second inlet opening. At least one heating heat exchanger is disposed in the hot air passage in order to heat the air in the hot air passage with a mixing chamber for mixing a first partial air flow from the cold air passage and/or a second partial air flow from the hot air passage. The mixing chamber is disposed downstream of the hot air passage and of the cold air passage. A mixing flap substantially closes the first inlet opening. The housing downstream of the mixing chamber has a first outlet opening and at least one second outlet opening for the flowing of air out of the mixing chamber.

A vehicle includes a heating, ventilation and air conditioning (HVAC) system for heating and cooling a passenger compartment. The HVAC system includes a refrigerant loop and a coolant loop, and an auxiliary heating, ventilation and air conditioning (HVAC) system. The auxiliary HVAC includes an expansion device coupled to the refrigerant loop for controlling a flow of refrigerant to a first heat exchanger, and a second heat exchanger coupled to an auxiliary coolant loop used to regulate a temperature of the component. The auxiliary HVAC further includes a blower for creating an air flow through the first heat exchanger, a first blend door for directing the air flow through the second heat exchanger and/or an outlet, a second blend door for directing the air flow through the outlet and/or a recirculation duct, and a third blend door for controlling the air flow through the recirculation duct.

An air circulator for a vehicle is provided. The air circulator includes a blower case and a connection duct that is connected to an outlet of the blower case. The connector duct includes a first path and a second path that are divided by a separation plate. Additionally, a filter is mounted in the outlet of the blower case and an inlet door is mounted in the blower case to selectively allow air to be blown into the first path and/or the second path.

Disclosed are an air outlet structure, an air outlet method for an air conditioner, and the air conditioner. The air outlet structure may include: a main air outlet channel, a main air outlet, an auxiliary air outlet and an adjusting device; the main air outlet and the auxiliary air outlet are communicated with the main air outlet channel; the adjusting device is provided between the main air outlet channel and the auxiliary air outlet as to make the main air outlet channel send out air through the main air outlet and/or the auxiliary air outlet. With the above structure, the air conditioner may have a broad air supplying scope and a uniform air speed and supply the air to an entire plane, and comfort of the air conditioner may be improved. Thus, the problem that an existing air conditioner has non-uniform air outlet effect may be effectively solved.

An HVAC module having a reconfigurable bi-level duct system is disclosed. The air duct includes an air duct inlet in fluid communication with the HVAC module, an interior wall dividing the air duct into first and second air passageways, a bypass port enabling fluid communication between the first air and second air passageways. A downstream control valve disposed adjacent the bypass port and is configured to selectively direct air flow from one of the first and second air passageways to the other of the first and second air passageways. An upstream flow control valve is disposed adjacent to the inlet of the air duct, wherein the upstream flow control valve is configured to selectively direct air flow from the hot and cold chambers of the HVAC module to the first and second air passageways of the air duct.

Provided is a register that can more surely suppress abnormal noise caused by air passing through a space between a damper and a retainer. An inner wall of an upper side wall of the retainer is formed with a plurality of rib parts provided on a downstream side relative to an outer periphery on the downstream side of a plate member in a closed state of a damper. The plurality of rib parts is arranged in a direction parallel to a turning axis of the damper, and adjacent rib parts are formed into different shapes. A soft seal member is provided with a plurality of protrusion parts on an upper surface of the outer periphery on the downstream side of the plate member.
