摘要： The invention provides a heat pump system and method heat pump system comprising a first Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) core and adapted to convert movement of the core into energy in response to a temper-reature change. A second Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) core in fluid communication with the first core and adapted to convert movement of the second core into energy. A third Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) or elastocaloric core in fluid communication with the first and second cores and adapted to convert movement of the third core into energy. The first core, second core and the third core are arranged in series and a control system provides waste pressure from the first core to the second core and/or third core.
