Abstract:
The thermodynamic efficiency of using the multicaloric effect ($\mu$CE) in solid-state cooler systems has been studied in comparison to single-component caloric effects. This approach is illustrated by example of the Brayton cycle for $\mu$CE and magnetocaloric effect (MCE). Based on the results of experiments with Fe$_{48}$Rh$_{52}$–PbZr$_{0.53}$Ti$_{0.47}$O$_{3}$ two-layer ferroic composite, the temperature dependence of the relative efficiency is determined and the temperature range is estimated in which the $\mu$CE is advantageous to MCE. The proposed theory of $\mu$CE is compared to experimental data.
