Elastocaloric heating/cooling using shape memory alloys (SMAs) offers a potential solution to the use of ozone-depleting refrigerants found in common heat pump/refrigeration cycles. Recent studies have shown that the Coefficient of Performance (COP) for elastocaloric cycles is comparable to (or greater than) those achieved with standard HVAC systems of the same scale. In this study, COMSOL Multiphysics is used to model the behavior of a SMA as strain is applied/released around a bend, and subsequently optimize its performance based on a parametric study to identify the parameters that will maximize COP, endothermic temperature change, and cooling power.
