Abstract
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.
