    Abstract: A vapor injection heat pump includes a coolant loop and a refrigerant loop. The refrigerant loop includes a compressor, a valve directing a refrigerant of the compressor to a first or second heat exchanger dependent upon a mode of operation, an expansion device receiving the refrigerant from at least one of the heat exchangers, a separator receiving an expanded liquid/vapor refrigerant mix from the expansion device and directing a vapor component to a first input port of the compressor and a liquid component to a second valve. The second valve directs the liquid component to the heat exchangers, dependent upon the mode, and an accumulator receives an output refrigerant of the heat exchangers dependent upon the mode and directs a vapor component to a second input port of the compressor. A control module controls a pump in the coolant loop and the first and second valves dependent upon the mode.

    Abstract: A vehicular air-handling system includes a blower assembly for a vehicle having a fan and a return-air baffle operable between a fresh-air position. The fan is in communication with a fresh-air duct and a recirculating position and the fan is at least partially in communication with a recirculating duct. A noise-attenuating end of the recirculating duct is positioned below an instrument panel of the vehicle and oriented substantially perpendicular to a portion of a floor below the instrument panel, wherein noise from the fan drawing air through the recirculating duct is directed into the floor below the instrument panel.

    CPC classification number: B60H1/249

    Abstract: An automotive vehicle air extraction system in fluid communication with a cabin of the vehicle is provided. The extraction system may have a housing arrangement and a pair of extractors attached to the housing arrangement. A chamber may be formed between the housing arrangement and pair of extractors. An air pump may be in fluid communication with the chamber. The pair of extractors may be an inner extractor and an outer extractor. A controller may be configured to activate the air pump to supply airflow to the chamber to close the inner extractor and/or prevent inadvertent opening of the inner extractor.

    Abstract: A vehicle includes a heating, ventilation and air conditioning (HVAC) system for heating and cooling a passenger compartment. The HVAC system includes a refrigerant loop and a coolant loop, and an auxiliary coolant loop for heating and cooling at least a portion of the passenger compartment. The auxiliary coolant loop includes a pump for moving a coolant, within the auxiliary coolant loop, through a first heat exchanger coupled to the refrigerant loop via an expansion device, a second heat exchanger positioned within the passenger compartment, and a third heat exchanger coupled to the coolant loop. A flow control valve controls a flow of coolant to the third heat exchanger. The temperature of the coolant within the auxiliary coolant loop is controlled utilizing the flow valve and the pump. The first and third heat exchangers may be in parallel for controlling the movement of coolant there between to control temperature.
