Abstract

Official abstract text for this publication.

The disclosure relates to a unitary heat pump air conditioner (Unitary HPAC) having a plate type exchanger assembly, an electrically driven compressor, and coolant pumps. The plate heat exchanger assembly includes a plurality of plates stacked and hermetically sealed between an upstream end plate and a downstream end plate. The stacked plates define a condenser/chiller portion adjacent the upstream end plate, an accumulator portion adjacent the downstream end plate, and an evaporator/chiller portion sandwiched between the condenser/chiller portion and the accumulator portion. A refrigerant passageway extends through the plate type heat exchanger assembly, a hot coolant passageway extends through the condenser/chiller portion, and a cold coolant passageway extends through the evaporator/chiller portion. The cold coolant passageway and the hot coolant passageway are in non-contact thermal communication with the refrigerant passageway.
