The Elastocaloric Effect: A Way to Cool Efficiently

The elastocaloric alloys Ni-Ti and Cu-Zn-Al in a regenerative refrigeration device can produce outstanding results with up to 20-times larger specific cooling powers compared to gadolinium, a benchmark magnetocaloric material, with comparable coefficient-of-performance (COP) values (≈5). These results can open up a new way of making cooling devices with more compact systems and provide the possibility to avoid expensive rare-earth materials.
