The disclosure relates to a unitary heat pump air conditioner (Unitary HPAC) having a plate type hot-side heat exchanger assembly, a cold-side heat exchanger assembly, and electrically driven compressors and coolant pumps. The plate type hot-side heat exchanger assembly includes a plurality of plates stacked and hermetically sealed between an upstream end plate and a downstream end plate, defining a condenser/chiller portion having a first coolant passageway, a sub-cooler portion having a second coolant passageway, and a refrigerant receiver portion sandwiched between the condenser/chiller portion and the sub-cooler portion. The first coolant passageway and the second coolant passageway are in non-contact thermal communication with the refrigerant passageway.

1. A unitary heat pump air conditioner, comprising: a hot-side heat exchanger assembly having a plurality of plates stacked and hermetically sealed between an upstream end plate and a downstream end plate, defining: a condenser/chiller portion adjacent said upstream end plate, wherein said upstream end plate includes a refrigerant inlet and a hot coolant outlet;a sub-cooler portion adjacent said downstream end plate, wherein said downstream end plate includes a refrigerant outlet, a hot coolant inlet, a sub-cooler coolant inlet and a sub-cooler coolant outlet;a refrigerant passageway in hydraulic communication with said refrigerant inlet and said refrigerant outlet, wherein said refrigerant passageway extends through said condenser/chiller portion and said sub-cooler portion;a first coolant passageway in hydraulic communication with said hot coolant inlet and said hot coolant outlet, wherein said first coolant passageway extends through said condenser/chiller portion; anda second coolant passageway in hydraulic communication with said sub-coolant inlet and said sub-coolant outlet, wherein said second coolant passageway extends through said sub-cooler portion;wherein said first coolant passageway and said second coolant passageway are in non-contact thermal communication with said refrigerant passageway,wherein said unitary heat pump air conditioner forms a unitary subassembly having a compact size suited for installation in at least one of the following locations in a passenger vehicle: a vehicle trunk, under a vehicle hood, within a vehicle dashboard, or under vehicle seats. 2. The unitary heat pump air conditioner of claim 1, wherein said hot-side heat exchanger assembly further defines a refrigerant receiver portion sandwiched between said condenser/chiller portion and said sub-cooler portion, wherein said refrigerant passageway extends through said refrigerant receiver portion. 3. The unitary heat pump air conditioner of claim 2, wherein said refrigerant passageway meanders through at least one of said condenser/chiller portion, said receiver portion, and said sub-cooler portion. 4. The unitary heat pump air conditioner of claim 3, wherein said refrigerant passageway enters top portion of said receiver portion from said condenser/chiller portion and exits bottom portion of said receiver portion to said sub-cooler portion. 5. The unitary heat pump air conditioner of claim 2, wherein said plurality of stacked plates of hot-side heat exchanger assembly further defines a first coolant header extending linearly through both said receiver portion and sub-cooler portion, and in hydraulic communication with said first coolant passageway extending through said condenser/chiller portion and said hot coolant inlet. 6. The unitary heat pump air conditioner of claim 5, wherein said first hot coolant passageway meanders through said condenser/chiller portion. 7. The unitary heat pump air conditioner of claim 5, wherein said second hot coolant passageway meanders through said sub-cooler portion. 8. The unitary heat pump air conditioner of claim 5, wherein said first hot coolant passageway is in non-contact counter-flow with said refrigerant passageway. 9. The unitary heat pump air conditioner of claim 3, further comprising: a cold-side heat exchanger assembly having a refrigerant inlet in hydraulic communication with said refrigerant outlet of hot-side heat exchanger assembly and a refrigerant outlet in hydraulic communication with said refrigerant inlet of hot-side heat exchanger assembly; andan electrically driven compressor for circulating a refrigerant through said cold-side heat exchanger assembly and said hot-side heat exchanger assembly such that heat energy is transferred from said cold-side heat exchanger assembly to said hot-side heat exchanger assembly. 10. The unitary heat pump air conditioner of claim 9, further comprising an electrically driven hot side coolant pump in hydraulic communication with said coolant inlet of hot-side heat exchanger assembly and an electrically driven cold side coolant pump in hydraulic communication with a coolant inlet of said cold-side heat exchanger assembly. 11. A plate type hot-side heat exchanger assembly for a unitary heat pump air conditioner, comprising: a plurality of plates stacked and hermetically sealed between an upstream end plate and a downstream end plate, defining:a condenser/chiller portion adjacent said upstream end plate, wherein said upstream end plate includes a refrigerant inlet and a hot coolant outlet;a sub-cooler portion adjacent said downstream end plate, wherein said downstream end plate includes a refrigerant outlet, a hot coolant inlet, a sub-cooler coolant inlet and a sub-cooler coolant outlet;a refrigerant receiver portion sandwiched between said condenser/chiller portion and said sub-cooler portion;a refrigerant passageway in hydraulic communication with said refrigerant inlet and said refrigerant outlet; wherein said refrigerant passageway extends through said condenser/chiller portion and said sub-cooler portion;a first coolant passageway in hydraulic communication with said hot coolant inlet and said hot coolant outlet; anda second coolant passageway in hydraulic communication with said sub-coolant inlet and said sub-coolant outlet;wherein said first coolant passageway and said second coolant passageway are in non-contact thermal communication with said refrigerant passageway,wherein the plate type hot-side heat exchanger has a size suited for installation within a unitary heat pump air conditioner that forms a unitary subassembly suited for installation win at least one of the following locations in a passenger vehicle: a vehicle trunk, under a vehicle hood, within a vehicle dashboard, or under vehicle seats. 12. The plate type hot-side heat exchanger assembly for a unitary heat pump air conditioner of claim 11, wherein said refrigerant passageway enters top portion of said receiver portion from said condenser/chiller portion and exits bottom portion of said receiver portion to said sub-cooler portion. 13. The plate type hot-side heat exchanger assembly for a unitary heat pump air conditioner of claim 12, further comprising a first coolant header extending linearly through both said receiver portion and sub-cooler portion, and in hydraulic communication with said first coolant passageway extending through said condenser/chiller portion and said hot coolant inlet.
