Abstract:
The efficiency of using the multicaloric effect ($\mu$CE) in solid-state cooling systems is investigated and compared with single caloric effects. The proposed approach is illustrated by the example of the Brighton cycle for $\mu$CE and the magnetocaloric effect. Based on the conducted experiments for the two-layer composite Fe$_{48}$Rh$_{52}$-PbZr$_{0.53}$Ti$_{0.47}$O$_{3}$, the dependence of relative efficiency on temperature is constructed and the temperature range is estimated, where $\mu$CE has an advantage over the magnetocaloric effect. The comparison of the developed theory of the $\mu$CE with the obtained experimental data is performed.
