  • Patent number: 10532628
    Abstract: An HVAC module having a reconfigurable bi-level duct system is disclosed. The air duct includes an air duct inlet in fluid communication with the HVAC module, an interior wall dividing the air duct into first and second air passageways, a bypass port enabling fluid communication between the first air and second air passageways. A downstream control valve disposed adjacent the bypass port and is configured to selectively direct air flow from one of the first and second air passageways to the other of the first and second air passageways. An upstream flow control valve is disposed adjacent to the inlet of the air duct, wherein the upstream flow control valve is configured to selectively direct air flow from the hot and cold chambers of the HVAC module to the first and second air passageways of the air duct.

  • Patent number: 10286748
    Abstract: A method controls the discharge of temperature-conditioned air from a plurality of zone outlets of an automotive HVAC system via an open architecture multi-zone HVAC unit having a single blower fan, an evaporator downstream of the blower and a heater downstream of the evaporator, wherein each zone in the module includes a temperature mix door for proportioning hot and cold air, which is controlled by a separate Discharge Temperature Maintenance control (DTM control), and an output valve for controlling a zonal output flow rate. The output valve of each zone outlet is placed in an output valve position associated with a target resistance; and the single blower fan is operated at a minimum voltage required for generating a total requested blower output flowrate.

  • Patent number: 10197312
    Abstract: A heat exchanger includes a header, a plurality of tubes, and a distributor. The header is configured to contain refrigerant and define an opening proximate to a termination end of the header. The plurality of tubes extends away from and is fluidicly coupled to the header. The plurality of tubes includes a first group of adjacent tubes characterized as located further away from the opening than a second group of adjacent tubes. The distributor is located within the header and spaced apart from the opening such that a first portion of the refrigerant in the first group of tubes does flow through the distributor, and a second portion of the refrigerant in the first group of tubes does not flow through the distributor.

  • Patent number: 9879870
    Abstract: HVAC module has an air inlet, an evaporator downstream of the blower and a heater downstream of the evaporator, and a rear mixing zone downstream of the evaporator and the heater, wherein a control valve prevents cold air from flowing back towards the hot air by regulating the pressure of the cold air. A method is devised to control anti-backflow control valve of such an HVAC module by the steps of reading pressure and temperatures at various points in the HVAC module; setting air flow and temperature discharge targets; calculating the resistance of the control valve and a bland valve; determining corresponding control valve and blend valve positions; and moving the control valve and blend valve to those corresponding positions.

  • Patent number: 9809083
    Abstract: A heat pump cooling and heating system for an electric vehicle includes a range extending PCM heat exchanger (24), with a single acting phase change material with a melt temperature between the two comfort temperatures associated with cooling and heating, respectively. In a charging mode, as the vehicle batteries are charged, the same exterior current source runs the compressor (10), charging the PCM exchanger (24) with heat or “cold.” During an initial range extending mode, the PCM exchanger/reservoir (24) serves as the heat source or heat sink. The PCM material does not directly heat or cool the air, as is conventional, allowing a single reservoir material to be used in both heating and cooling modes.

  • Patent number: 9776471
    Abstract: HVAC unit has a single blower fan, an evaporator downstream of the blower and a heater downstream of the evaporator, wherein each zone outlet includes a temperature mixing door for controlling portions of hot and cold air and an output valve for controlling a zonal output flow rate. A method is devised to control the discharge of temperature-conditioned air from a plurality of zone outlets of an automotive HVAC system via such an HVAC unit by the steps of reading an operator-requested zonal discharge blower level for each of the zone outlets; converting each zonal discharge blower level request to a zonal flowrate request; calculating a total requested output flowrate as a summation of all zonal flowrate requests; and adjusting a blower voltage to a minimum voltage required for generating the total requested output flowrate.

  • Patent number: 9746255
    Abstract: A heat pump heat exchanger includes a first manifold, a second manifold spaced from the first manifold, a plurality of refrigerant tubes hydraulically connecting the manifolds, and a distribution tube disposed in the first manifold. The distribution tube includes an inlet end, a distal end opposite the inlet end, a plurality of orifices between the inlet end and the distal end. The distribution tube also includes a terminal aperture immediately adjacent the distal end, wherein the terminal aperture includes an open aperture area greater than any one of the open orifice area. The open aperture area is large enough to provide a uniform refrigerant collection with acceptable minimal pressure drop in evaporative mode, but small enough to prevent vapor overflow to an area of the manifold adjacent to the distal end in condenser mode. The length of the distribution tube is less than ¾ the length of the first manifold.
