Resumen
[EN]The connection between Carnot-like and low-dissipation refrigerators is proposed by means of
their entropy generation and the optimization of two uni ed, compromise-based gures of merit.
Their optimization shows that only a limited set of heat transfer laws in the Carnot-like model are
compatible with the results stemming from the low-dissipation approximation, even though there
is an agreement of the related physical spaces of variables. A comparison between two operation
regimes and relations among entropy generation, e ciency, cooling-power and power-input are ob-
tained, with emphasis on the role of dissipation symmetries. The results extend previous ndings
for heat engines at maximum power conditions.
