摘要:	We study the performance of minimally nonlinear irreversible refrigerators which works between a hot and cold heat reservoir of constant temperatures T-h and T-c (< T-h), respectively. Applying optimization criterion Omega or chi, we analyze the coefficient of performance (COP) at arbitrary value of chi or Omega and thus obtain the upper and lower bounds of the COP. Our results show that, for the optimized, tightly-coupled refrigerators, a small loss away from the maximum value of either chi or Omega figure of merit means a larger gain in the COP.
