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.

Variable evaporator outlet air pressure distribution

The present disclosure describes an air conditioning apparatus comprising an air conditioning case defining an airflow passage, an evaporator accommodated in the air conditioning case, a first blower located at an upstream side of the evaporator creating a first airflow in the airflow passage, a second blower located at an upstream side of the evaporator creating a second airflow in the airflow passage, and a controller electrically connected to the first blower and the second blower. The controller controls the first blower and the second blower based on a target total airflow amount. The first airflow and the second airflow are mixed at the upstream side of the evaporator. The air conditioning apparatus further comprises means for preventing the first airflow from being directed into the second blower.

Air conditioning apparatus

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.

Multi-blower HVAC layout for improved evaporator performance

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.
