Abstract: A unitary defroster system for a motor vehicle windshield comprises an instrument panel substrate, an HVAC supply source, and an air supply plenum in fluid communication with the HVAC supply source and terminating in a plurality of individually configured defroster nozzle ducts conjoined with the instrument panel substrate and aligned in a substantially linear row parallel to and proximate an interior surface of the windshield. The unitary defroster system is formed by an additive manufacturing process and at least two of the ducts are configured and arranged to deliver a different air flow to the interior surface of the windshield.

Abstract: The present disclosure extends to methods, systems, and computer program products for controlling climate in vehicle cabins. A person may provide climate related data to a vehicle climate control system prior to pick up and/or during a ride in the vehicle. The climate control system may adjust the climate in at least part of a vehicle cabin based at least in part on the climate related data and configuration of components in the climate control system. Climate control adjustments can be used to precondition part of a vehicle cabin for a person and/or in response to indicated thermal discomfort of the person. The climate control system can refer to an occupant comfort model and compute climate adjustments in accordance with the occupant comfort model.

Abstract: An air duct includes an inlet and an outlet that are interconnected with one another by a curved intermediate portion. A plurality of chambers are disposed within the curved intermediate portion. Each chamber of the plurality of chambers includes a first end opening into the inlet and a second end opening into the outlet. An enclosed body portion interconnects the first and second ends of each chamber. The curved intermediate portion further includes a first cross-sectional configuration disposed at a first portion of the curved intermediate portion, and a second cross-sectional configuration that is different from the first cross-sectional configuration disposed at a second portion of the curved intermediate portion. The second portion of the curved intermediate is disposed downstream from the first portion of the curved intermediate portion. The air duct directs airflow in a demisting sequence and is further contemplated to be formed using an additive manufacturing process.

Abstract: A vehicle is provided herein. The vehicle includes a windshield positioned between an instrument panel and a headliner. A duct is positioned above the headliner and has an inlet and an outlet. An air conditioning system is configured to push conditioned air out of the instrument panel generally toward the inlet. A fan is proximate the inlet and is configured to draw the conditioned air into the inlet and push the conditioned air out of the outlet toward a vehicle window proximate the outlet.

Abstract: An air extraction system is provided for a motor vehicle. That air extraction system includes a trim air discharge outlet, an extractor and an extractor duct extending between the trim air discharge outlet and the extractor. The extractor duct is tuned to dissipate duct noise at at least one particular duct noise frequency characteristic of the extractor duct.

Abstract: A HVAC system including a multi-function unit for conditioning and controlling the flow of refrigerant. The multi-function unit may be contained within a housing that houses a receiver/dryer, integral heat exchanger and thermal expansion valve.

Abstract: An air conditioning system for a start-stop vehicle employs a compressor with a variable displacement. A controller determines a normal Climate Thermal Load (CTL) value for controlling a variable stroke of the variable displacement compressor. A stop event is detected in response to a speed of the vehicle and the occurrence of a predetermined deceleration. During the stop event, the variable stroke is increased by an amount determined in response to the normal CTL value, the speed of the vehicle, and a measure of the deceleration of the vehicle so that an evaporator temperature within the air conditioning system is allowed to decrease while the vehicle is stopping so that climate comfort can be maintained even while the engine is shut off during the subsequent time that the vehicle is stopped.

Abstract: A heat exchanger assembly having first and second heat exchangers having a tube-fin construction. The first heat exchanger is configured to cool a first fluid. The second heat exchanger has a first portion for cooling the first fluid and a second portion for cooling a second fluid. Cooling air passes through the first heat exchanger before passing through the second heat exchanger.
