Abstract: An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a first inlet portion and a second inlet portion. The first inlet portion includes a first recirculation inlet configured to receive recirculated air originating from a passenger compartment of the vehicle and a first ambient air inlet configured to receive ambient air originating from an ambient environment. The second inlet portion includes a second recirculation inlet configured to receive recirculated air originating from the passenger compartment of the vehicle and a second ambient air inlet configured to receive the ambient air originating from the ambient environment. A first air distribution door and a first baffle door are disposed in the inlet section to selectively control a distribution of the recirculated air and the ambient air entering the first inlet portion.

Abstract: An air-handling system includes an evaporator core and a downstream arranged heater core disposed in an air-handling casing. A primary flow path is formed within the air-handling casing and leads to a primary zone of a passenger compartment. The primary flow path is divided into a primary cool air pathway bypassing the heater core and a primary warm air pathway passing through the heater core. A secondary flow path is formed within the air-handling casing and leads to a secondary zone of the passenger compartment. The secondary flow path includes a secondary cool air pathway branching from the primary flow path downstream of the evaporator core and a secondary warm air pathway branching from the primary flow path downstream of the heater core. The secondary cool air pathway bypasses the heater core and the secondary warm air pathway passes through the heater core.

A secondary portion is interchangeable between a first plenum in the first configuration of the main housing and a second plenum in the second configuration of the main housing.

Abstract: An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a recirculation inlet in fluid communication with a passenger compartment of the vehicle and a fresh air inlet in fluid communication with an ambient environment. An air distribution door is disposed in the inlet section for controlling a distribution of air entering the inlet section through the recirculation inlet and the fresh air inlet. A baffle door is disposed in the inlet section for selectively reducing a flow area through the fresh air inlet to accommodate a ram air pressure induced by motion of the vehicle relative to fresh air of the ambient environment.

Abstract: A heat pump system for a vehicle comprises a heating, ventilating, and air conditioning module as well as a refrigerant circuit including a compressor, an internal condenser, and an external condenser. The module comprises a warm air path including the internal condenser, a cold air path formed independently from the warm air path, a purge flow path branching from the warm air path at a position downstream of the internal condenser with respect to a flow of air through the module, and a purge control door adjustable between a first position preventing fluid communication between the warm air path and the purge flow path and a second position allowing fluid communication between the warm air path and the purge flow path. The purge flow path provides fluid communication between the warm air path and the ambient environment.

Abstract: An air-handling system for a heating, ventilation, and air conditioning system of a vehicle includes a main housing comprising a conditioning section, a mixing section, and a delivery section having a flow of air passing therethrough. The delivery section includes a conduit branching into a windshield defrost pathway and a demist pathway, the windshield defrost pathway leading to windshield defrost vents of a passenger compartment of the vehicle and the demist pathway leading to side window defrost vents of the passenger compartment. A control door rotatably disposed in the conduit is adjustable through a range of rotational positions wherein a flow area through the windshield defrost pathway is variably restricted while the demist pathway remains unobstructed. The control door is further adjustable to a position wherein the windshield defrost pathway and the demist pathway are closed.

Abstract: A climate control system for a vehicle comprises a housing and a diverter. The housing has a first conduit formed therein. The first conduit includes a first subconduit formed in an intermediate portion of the first conduit and a second subconduit disposed adjacent an end of the first subconduit. The diverter is rotatably disposed within the first conduit, and includes a first member having an outer edge and an offset edge. The outer edge is disposed on a first planar portion of the first member and configured to sealingly contact a wall of the first subconduit when the diverter is in a first position. The offset edge is disposed on a second planar portion of the first member and configured to sealingly contact a portion of the second subconduit when the diverter is in the first position.

Abstract: An air handling system for a vehicle comprises a conditioning section for controlling a temperature of a flow of air, a mixing section disposed downstream of the conditioning section with respect to a direction of the flow of the air, and a delivery section disposed downstream of the mixing section with respect to the direction of the flow of the air. The delivery section includes a first chamber, a second chamber, and a third chamber. A dividing plate separates each of the second chamber and the third chamber into a first side portion to a first side of the dividing plate and a second side portion to an opposing second side of the dividing plate. The second side portion of the third chamber is configured to primarily direct the flow of the air towards a rear seat area of the vehicle.
