Precise direct measurements of the intensive electrocaloric effect (ECE) in commercial multilayer capacitor
based on doped BaTiO3 were performed using an adiabatic calorimeter. High reversibility of ECE studied
under equilibrium thermal conditions was observed. The nonequilibrium thermal conditions caused by
fixing the temperature of one of the ends of the linear EC element lead to the predominance of ECE when the
electric field is turned off. The heat flow through the EC element appearing under the influence of a periodic
electric field and depending on its frequency makes it possible to create a cooling cycle without thermal
keys.
