摘要：

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 Fe48Rh52-PbZr0.53Ti0.47O3 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.
