Elastocaloric Cooling


The use of the vapor compression cycle (VCC) has resulted in unpredicted environmental damage such as depleting the ozone layer and promoting global warming when its refrigerant leaks into the atmosphere. One way to tackle this problem is to develop cooling cycles using solid-state refrigerants: the caloric materials. The main characteristic of caloric materials is that it is possible to induce a phase transition in solid phase with the application of an external field, which translates in an adiabatic temperature increase or an isothermal entropy change. In this work, we present the main steps to use this caloric effect for cooling and two system integration possibilities for elastocaloric cooling systems.
