A method for servicing a blower motor installed in a heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle may include rotating a scroll housing subassembly of the HVAC assembly from an installed position to an extraction position. The method may include detaching a first securing element, the first securing element being distributed on the scroll housing subassembly and an evaporator housing subassembly of the HVAC assembly. The method may include removing the scroll housing subassembly from the HVAC assembly in a direction of extraction. The method may include that the scroll housing subassembly reaches the extraction position by axial rotation in a direction orthogonal to the direction of extraction. The method may include that the extraction position is a position at which the scroll housing subassembly is cleared for moving in the direction of extraction.

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

A heating, ventilation, and air-conditioning (HVAC) assembly for managing air mixing door kinematics of a motor vehicle is disclosed. The assembly includes a first door configured for allowing passage of a first air flow, a second door configured for allowing passage of a second air flow, obtaining means configured to obtain a temperature command indicating a target temperature for a passenger cabin, identifying means configured to identify a pattern of non-linear door kinematics for mixing the first air flow and the second air flow based on the temperature command, coordinating means configured to coordinate the non-linear door kinematics between the first door and the second door, and mixing means configured to mix the first air flow and the second air flow.

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.

A system for controlling movements of doors of an HVAC module includes an actuation gear and an intermediate cam. A main door includes a first portion and a second portion having a first guide. The first portion engages with actuation gear to enable linear movement of the main door. A slave door includes a second engagement element and moves between a blocking and unblocking position based on movement of main door. The intermediate cam moves angularly and includes a first engagement element and a second guide. The first engagement element interacts with the first guide, and the second guide interacts with second engagement element to facilitate angular movement of slave door in response to movement of the main door. The first guide includes a bend positioned to enable angular movement of the slave door after the main door moves a pre-determined distance.

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.

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.

The present invention provides a vehicle ventilation system, and, in particular, a heating and air-conditioning assembly and method of making such an assembly, wherein the assembly comprises a multi-portion HVAC housing and an alignment feature. The alignment feature preferably follows the contours of the housing portions of the HVAC. Preferably, the alignment feature is a baffle, or, in particular, a cross flow baffle, that serves an air directing as well as bridge function between housing portions of the HVAC, reducing packaging space for the HVAC unit while providing ease of assembly and reduced tool complexity for multi-piece HVAC housings.
