Abstract Elastocaloric refrigeration using superelastic NiTi shape memory alloys (SMAs) has attracted much attention recently because it a large energy saving potential, no environmental effects, and low cost. Achieving the continuous operating of elastocaloric devices, i.e., separating cold hot areas on physically, helps efficient release absorption heat avoid reciprocal parts intervals outputs in system. In this paper, an analytical model proof-of-concept experiments for (elasto)caloric devices are presented. The experimental concept was developed based set rotating sheets with which copper sink source contact cyclically.
