Abstract

See full text

An apparatus, which may be operated as a heat engine and/or a heat pump, includes moveable separators at a cold side and/or moveable separators at a hot side. Each separator divides a volume into two smaller volumes. Working fluid may be sequentially filled and emptied from volumes between the separators. The separators may move to maintain uniform pressure in the volumes. Hot-side separators may allow for near adiabatic compression/expansion of working fluid. Cold-side separators may allow for near adiabatic expansion/compression of working fluid. Two displacers are positioned between the cold-side separators and the hot-side separators. The displacers are independently actuatable to force working fluid into and out of the volumes between separators and into and out of a variable intermediate volume between the displacers. Heat exchangers, including a warming heat exchanger, are provided to heat, cool, and warm working fluid as it flows between separated volumes and the intermediate volume.
