Y. Izumida, K. Okuda, A. Calvo Hernández, J. M. M. Roco
We apply the model of minimally nonlinear irreversible heat engines developed by Izumida and Okuda [EPL {\bf 97}, 10004 (2012)] to refrigerators. The model assumes extended Onsager relations including a new nonlinear term accounting for dissipation effects. The bounds for the optimized regime under an appropriate figure of merit are analyzed and successfully compared with those obtained previously for low dissipation Carnot refrigerators in the finite-time framework. Explicit derivation of the Onsager coefficients is also presented.
