The performance of a micro-/nano-scaled Ericsson refrigeration cycle using an ideal Fermi gas as the working substance is examined, in which the finite-size of the working substance is taken into account. It is found that finite-size effect always results in the decrease of the coefficient of performance compared with that obtained under the thermodynamic limit condition. The influence of the finite-size effect on the performance characteristics is observable when the refrigeration cycle is operated in the temperature region around the Fermi temperature $T_F$ of the working substance, but negligible when the working temperatures are much lower or higher than $T_F$ . The results obtained here may be helpful for further understanding quantum boundary effect of small systems and provide theoretical guidance for designing a micro-/nano-scaled cycle device.
Keywords:Ericsson quantum cycle; finite-size effect; coefficient of performance; Fermi temperature
