Résumé

Elastocaloric refrigeration has attracted widespread attention due to its high energy density,andnumerous elastocaloric cooling prototypes have been developed. However, when stacking multiple regenerator layers for scaling up, the dead volume between layers will have a significant impact on the performance of the regenerators. In this study, we conducted experimental research on tubular elastocaloric regeneratorsdriven by compression. Firstly, we constructed an31-tube regenerator with a temperature span of 18.2K.Subsequently, by stacking two 31-tube regenerators, we developed a double-layer regenerator with 62 tubes, and its maximumtemperature span reached 25.2K. To reveal the contribution of dead volume, we used 59 tubes to form a single-layer regenerator as a comparison, which featureda maximum temperature span of 27.2K. It means that the dead volume between layers had at least 8% impact on the system's cooling performance.
