Elastocaloric refrigeration is characterized by a high energy efficiency and drastic temperature change, and it requires no refrigerant. It is the best candidate for the non-gas-liquid compression refrigeration technology, which has the advantage of alternate absorption and release of latent heat during solid-solid phase transformation to realize refrigeration. Compared with the magnetocaloric and electrocaloric refrigeration, elastocaloric refrigeration exhibits advantages such as low cost, high cooling rate, and high efficiency. Elastocaloric refrigeration mainly employs shape memory alloys, which have been a research focus in the past decades. This study describes the mechanism and test methods of the elastocaloric effect and summarizes the research progress as well as challenges in the Ti-Ni-based, Cu-based, Fe-based, and Heusler-type shape-memory alloys as elastocaloric materials. Furthermore, a brief perspective on research directions of the elastocaloric effect based on shape memory alloys is presented herein.
