A climate control system for a vehicle having a plurality of modes includes an evaporator having a downstream face. The system also includes at least one blower that blows air across the evaporator. The air downstream of the blower has a pressure distribution defined generally along the downstream face. The pressure distribution along the downstream face is variable depending on which of the plurality of modes the climate control system is currently set.

An air conditioning device includes a casing that provides multiple air passages, a blower fan that suctions an air from the multiple air passages and blows out the air in the casing, a suction side partitioning member that is disposed on a suction side of the blower fan in the casing and separates air flows from the multiple air passages from each other, and a blowing side partitioning member that is disposed on a blowing side of the blower fan in the casing and separates the air flows from the multiple air passages from each other. The suction side partitioning member and the blowing side partitioning member are disposed so that a relative position of the blowing side partitioning member to the suction side partitioning member is deviated in a rotation direction of the blower fan.

A register faces a specific seat and feeds air to the specific seat. An hypothetical reference line is defined that extends in the front-back direction of the specific seat through the center in the width direction of the specific seat. In comparison between a first bezel side wall and a second bezel side wall, the second bezel side wall is positioned closer to the reference line than the first bezel side wall. A second duct side wall is bent such that a downstream side of the second duct side wall is positioned farther in the width direction from the reference line than an upstream side of the second duct side wall.

A defrost airflow assembly for a heating, ventilation, and air-conditioning (HVAC) case, having a defrost channel starting in a mixing chamber and terminating in a defrost outlet with a defrost door, a demist channel starting in the mixing chamber and terminating in a demist outlet with a demist door, and a bypass channel connected directly with the post-door defrost channel and the post-door demist channel, and indirectly with the pre-door demist channel and the pre-door defrost channel. The first bypass channel is configured to allow airflow from the mixing chamber to the defrost outlet when the defrost door is in the closed position and the demist door is in the open position.

An arrangement for the air distribution of an air conditioning system (1) of a motor vehicle. The air conditioning system (1) is configured with a housing (2) with at least two flow paths (6, 7), which empty into a mixing chamber (8), and at least one air outlet (3a, 3b, 3c) as well as an air flap (10, 11, 12) which can open and close the at least one air outlet (3a, 3b, 3c). The arrangement has a device (18) for air mixing with at least one air resistance element (21), which is supported so that it can turn about an axis of rotation (20) and which extends in the direction of the axis of rotation (20). The air resistance element (21) is configured with at least one flow through opening, so that depending on the position of the device (18) a cross section of at least one flow path (6, 7) of the housing (2) can be changed.

A panel and defrost plenum includes a manifold section, an air feed section and a branch section. The manifold section includes a first air distribution door, a second air distribution door and an optional third air distribution door. The manifold section also includes at least one actuator to displace the first air distribution door, the second air distribution door and the optional third air distribution door if present, between multiple operating positions. The air feed section is located upstream of the manifold section and functions to deliver an airstream past a package restriction to the manifold section. The branch section is downstream from the manifold section. A related method of routing an airstream past a package restriction is also disclosed.

A heating, ventilation, and air conditioning unit includes a case, a door, an actuator, and a holding member. The case has a first wall, a second wall, and a third wall. The first wall and the second wall are connected by the third wall to face each other. The door is rotatably disposed inside the case through a rotational axis. The door rotates about the rotational axis to selectively open and close an air outlet. The actuator rotates the door between a closed position where the door closes the air outlet and an open position where the door opens the air outlet. The holding member is disposed in the second wall and holds the door when the door rotates to the open position by engaging the door.

An air conditioning case in an air conditioning unit for a vehicle forms a first air passage, a second air passage bypassing the first air passage, and a mixing space connected to a first blowing port and a second blowing port through which air is blown out into a vehicle interior. A cooling heat exchanger cools and allows air to flow into the first air passage and the second air passage. A heating heat exchanger is disposed in the first air passage. A tunnel forming portion provides a tunnel passage into which a part of air from the first air passage flows. The tunnel forming portion includes a first outflow portion connected to the first blowing port, and a second outflow portion connected to the second blowing port, and separates the air flowing in the tunnel passage from the air flowing from the second air passage.

The purpose of the present invention is to improve the performance of an aspirator. A vehicular air conditioning device (1) includes: a case body; an evaporator (20); a heater core (40); and an aspirator (50) for guiding air in a vehicle cabin to a temperature detection unit. The case body integrally includes a case upstream portion (12) in which the evaporator (20) and the heater core (40) are stored, and a case downstream portion (13) in which the air circulated through the case upstream portion (12) is circulated. The case upstream portion (12) includes a first flow path portion (16a) that circulates the air in a Z-axis direction, and a second flow path portion (16b) that connects to a downstream side of the first flow path portion (16a), and circulates the air in a Y-axis direction. The aspirator (50) includes a primary air introduction portion (53), and is mounted at a central portion of the case body. The primary air introduction portion (53) includes an inlet (53d) formed at an upstream end, and introduces the air in the case body from the inlet (53d). The upstream end of the primary air introduction unit (53) is connected to the second flow path portion (16b) from the Z-axis direction.
