    Abstract: 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 temperature 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.

    Abstract: The invention provides a heat pump system and method comprising a first Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) elastocaloric core positioned in a housing and adapted to absorb heat and store energy in response to a first fluid inputted at a first temperature. The housing is configured to receive the first fluid at a first temperature via an inlet to cause the first SMA or NTE elastocaloric core to change state. A device is configured to apply stress on the first SMA or NTE core in the housing to cause the SMA or NTE elastocaloric core to change state, releasing heat/energy and causing the SMA/NTE to heat up. A second fluid at a higher temperature is inputted and then subsequently heated further as a result of heat transfer. A second Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) or elastocaloric core is positioned in a cascade arrangement with the first core, but exhibiting a higher activation temperature. The higher temperature fluid leaving core 1 is inputted into core 2, resulting in a larger net temperature lift than could be achieved with a single core. In the alternative, in a cooling system, to achieve a lower temperature drop, the second core in the cascade can exhibit a lower activation temperatures than the first core. The cycle focus is on the endothermic stress release component where the SMA/NTE/elastocaloric core absorbs energy from the fluid. The first core results in a fluid stream drop and that then enters the second core with lower activation temperatures, resulting in a further drop of the output fluid during the cooling half of the cycle.
