Abstract: 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.

Abstract: A rotary door includes a shaft and a deflector. The shaft defines an inner passage and has axial ends defining at least one end opening. The deflector extends from the shaft. The shaft has a peripheral opening communicating with the at least one end opening through the inner passage.

Abstract: A heat exchanger includes tubes having tube inlets, an inlet tank having therein an inlet tank space, and a dynamic baffle disposed in the inlet tank space. The inlet tank has a tank inlet. The tubes include first tubes and second tubes. The first tubes are closer to the tank inlet than the second tubes are to the tank inlet. The first tubes include a nearest tube that is, among the tubes, closest to the tank inlet. The dynamic baffle is configured to, when the fluid pressure of the thermal fluid in the inlet tank space is below a specified value, suppress the flow rates of the plurality of first tubes, and, when the fluid pressure of the thermal fluid in the inlet tank space is at or above the specified value, increase the flow rate of at least one of the plurality of the first tubes.

Abstract: A climate control system of a vehicle includes an evaporator, a first blower, and a first blower passageway that receives air blown from the first blower. The system also includes a second blower and a second blower passageway that receives air blown from the second blower and that is fluidly independent of the first blower passageway. The system further includes a ducting assembly defining a common passageway that receives air from both the first and second blower passageways. The first and second blowers are configured to operate in parallel to deliver air to the common passage and across the evaporator.

Abstract: An HVAC system is provided for use in a vehicle. The HVAC system includes a HVAC housing having a duct opening formed in a wall. An auxiliary duct may be inserted into the opening formed in the wall to direct air to a specified location. The opening may form a flap that contacts the auxiliary duct and is held in place adjacent to the wall by the contact of the auxiliary duct. The location can of the duct opening can be anywhere along the HVAC housing or any ducts leading off the HVAC.

Abstract: An HVAC system is provided for use in a vehicle having a passenger compartment volume. The HVAC system includes a HVAC housing having a duct opening formed in an exterior sidewall thereof. An evaporator is further provided for exhausting air downstream that is cooler than the air on the upstream side. An auxiliary compartment, such as a storage bin, is spaced apart from the HVAC housing, such as in a remote location of the passenger compartment. An auxiliary duct fluidly interconnects the HVAC housing and the auxiliary compartment via the duct opening for transmitting the cool exhausted air to the auxiliary compartment to provide a cooling effect within the auxiliary location. The auxiliary duct, in some embodiments, is disposed external from the HVAC housing for improved service and retrofitting to existing HVAC systems.

Abstract: A vehicle vacuum cleaning system may have a portable vacuum module that employs a vacuum module case, a vacuum fan within the interior of the vacuum module case and a vacuum fan drive shaft coupled to the vacuum fan. The vacuum module attaches and detaches to an HVAC module within the vehicle. The HVAC module may utilize an HVAC case, an electric motor within the HVAC case, an HVAC fan drive shaft coupled to the electric motor and an HVAC fan coupled to the HVAC fan drive shaft. The vacuum fan drive shaft is adapted to receive rotational energy from the HVAC fan drive shaft, either directly or through an auxiliary shaft. The vacuum module may employ gears to increase the speed and drawing force of the vacuum fan. A debris receptacle is detachable to the vacuum module. The HVAC fan drive shaft ultimately drives the vacuum fan.

Abstract: A climate control system includes ducts and a blocking member that regulates airflow through the ducts. An evaporator is disposed within the ducting assembly. The system also includes first and second blowers that blow air across the evaporator into the ducts. Additionally, the system includes a controller that determines a first target airflow to be delivered to a first cabin area, a second target airflow to be delivered to a second cabin area, a total target airflow, and a position for the blocking member. A first percentage of the total target airflow to be delivered by the first blower is defined according to the first target airflow, the second target airflow, and the total target airflow. Moreover, the controller controls the first blower to provide the first percentage of the total target airflow and controls the blocking member to move to the determined one of the plurality of positions.
