What Is Elastocaloric Cooling and How Does It Work? Elastocaloric cooling is a solid-state refrigeration method that uses shape-memory alloys to pump heat by mechanically stressing and unstressing the material. It works by exploiting a reversible phase change that releases heat when the alloy is loaded and absorbs heat when it is unloaded. A new compression-based prototype using NiTi tubes recently reached a heat-source temperature of −12 °C from a 24 °C heat sink, a 36 °C temperature lift, without greenhouse-gas refrigerants (
