Электрокалорическое охлаждение является экологически безопасной технологией преобразования энергии. Электрическое поле, необходимое для возбуждения цикла электрокалорического охлаждения, может быть создано значительно проще и с гораздо меньшими затратами по сравнению с магнитными полями, используемыми для магнетокалорического охлаждения. Кроме того, электрическая мощность, необходимая для электрокалорического охлаждения, может обеспечиваться стационарными или мобильными солнечными батареями, а также аккумуляторами электромобиля. Это открывает совершенно новые возможности для экологически безопасного промышленного прогресса в развивающихся странах. На основе аналитически решаемой модели многослойного электрокалорического охладителя обсуждены свойства материалов, влияющие на эксплуатационные характеристики электрокалорических приборов. Особое внимание уделено объемному термическому сопротивлению и термическому сопротивлению интерфейсов. Даны оценки средней охлаждающей мощности стека микроэлектромеханического электрокалорического охладителя.

Materials properties affecting EC device operation are discussed based on an analytically tractable model of a layered EC refrigerator. Special attention was paid to thermal and interface thermal resistances. Estimates of the average cooling power of a stacked MEMS-based EC refrigerator were made.
