Abstract: A HVAC system (100) includes a housing (10) with at least one first inlet (20) and at least one second inlet (30) formed thereon, at least one first door (20a), at least one second door (30a) and an intermediate door (40). The first inlet (20) and the second inlet (30) is for ingress of a first fluid stream and a second fluid stream inside the housing (10). The first door (20a) and the second door (30a) moves with respect to the first inlet (20) and the second inlet (30) respectively to define an open configuration, a closed configuration and a partially open configuration thereof. The intermediate door (40) is disposed between the first inlet (20) and the second inlet (30) and moves between a deployed and an un-deployed configuration to respectively disrupt and allow fluid flow there across. The intermediate door (40) is a sliding door.

Abstract: A split heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle is disclosed. The split HVAC includes a first sub-assembly comprising an evaporator and a first airflow space, a second sub-assembly comprising a second airflow space, a single sealing element located between a wall and one of the first sub-assembly or the second-sub-assembly, and a first interfacing element that directly connects the first sub-assembly and the second sub-assembly. The single sealing element and the first interfacing element prevent any airflow leakage from both the first sub-assembly and the second sub-assembly, and one of the first sub-assembly and the second sub-assembly extends partially into the other of the first sub-assembly and the second sub-assembly.

Abstract: A Heating, Ventilation, and Air-Conditioning unit for a vehicle is provided. The HVAC unit comprises a housing, a first inlet, a second inlet first flap, and a third door. The first flap having a first door and a second door, attached to the first inlet. The first door is angularly movable with respect to the second door and adapted to move between a first position and a second position to open and close the first inlet. Further, the second door is angularly movable with respect to the first door and adapted to move between the first position and a third position to open and close air passage between the first inlet and the second inlet. The third door rotatably connected in the second inlet, and is movable between a closed position where the second inlet is closed and at least partially open position where the second inlet is partially open.

Abstract: A method for smart heating and Recirculation Air Management (RAM) using an HVAC assembly for a vehicle is disclosed. The method involves obtaining a first air pressure at a first fresh air inlet configured for allowing passage of fresh air in proportion to a first degree of aperture of the first fresh air inlet and the first air pressure, obtaining a second air pressure at a first recycled air inlet configured for allowing passage of recycled air in proportion to a second degree of aperture of the first recycled air inlet and the second air pressure, identifying a required mixed air pressure based on a combination of the first air pressure and the second air pressure, and dynamically modifying the first and second degrees of aperture to obtain the required mixed air pressure which remains constant regardless of parameters associated with the inside passenger cabin of the vehicle.

Abstract: An HVAC air inlet housing for a vehicle includes an air inlet housing having a top portion and a bottom portion. A fresh air duct, to convey fresh air from an air inlet to a blower, is defined by the air inlet housing. A water inlet port, to connect to an evaporator drain port via a hose, is defined in the bottom portion. The hose is to convey water from the evaporator drain port to the water inlet port. A water tunnel is defined by the air inlet housing to convey water from the water inlet port to a sluice defined in the bottom portion. The sluice is to convey water from the water tunnel to a sump defined in the bottom portion. A sump drain port is defined in the air inlet housing bottom portion in fluid communication with the sump to drain water from the sump.

Abstract: A sensor assembly includes a housing, a blower fixed relative to the housing, an air tunnel, a filter, a first drain, and a second drain. The air tunnel includes an inlet, a first turn, a second turn, a first portion extending upward from the inlet to the first turn, a second portion extending downward from the first turn to the second turn, and a third portion extending from the second turn to the blower. The filter is positioned between the first portion and the first turn. The first drain extends through the first portion. The second drain extends through the third portion.

Abstract: A fluid flow controller includes a housing defining a first and a second fluid path. A first door is in the first fluid path to selectably control a first flow through the first fluid path in response to a rotation of a first lever. A second door is in the second fluid path to selectably control a second flow through the second fluid path in response to a rotation of a second lever. A flexible kinematic link is to connect an actuator arm rotatable about an actuator arm axis to the first lever via first pin joints for rotation of the first door about the first pivot axis. A flexible link length is responsive to a compressive and a tensile load. A rigid link is to connect the actuator arm to the second lever via second pin joints for rotation of the second door about the second pivot axis.

Abstract: An HVAC air intake for a vehicle, includes an air intake housing disposed outside of a passenger compartment of the vehicle. A fresh air inlet is defined in an upper portion of the air intake housing. A drain is disposed in a sump portion of the air intake housing to drain water from the sump portion. A recirculation door is disposed in a recirculation airflow doorway defined in the air intake housing below the fresh air inlet and above the sump portion. The recirculation door prevents air from flowing upwardly, and water from flowing downwardly through the recirculation airflow doorway when the recirculation door is closed. A conduit is disposed in the air intake housing to convey water from the upper portion of the air intake housing, around the recirculation door, to the sump portion when the recirculation door is closed.

Abstract: The present invention relates to arrangement of devices, and, in particular doors, in the architecture of HVAC units. Where space is a consideration, having doors that are common and/or that can be used or nestled in a common operative space, reduce the need of inventory of different parts, and allow for use of smaller interior HVAC space volumes in HVAC units.
