Optimized Coefficient of performance of Power law dissipative Carnot like Refrigerator

Abstract: The present work investigates the generalized extreme bounds of the coefficient of performance (COP) for the power law dissipative Carnot-like refrigerator in the presence of non-adiabatic dissipation under $\chi$ and $\dot{\Omega}$ optimization criteria. The lower and upper bounds of the COP for the low dissipation Carnot-like refrigerator under $\chi$ and $\dot{\Omega}$ optimization criteria are obtained with power law dissipation level $\delta=1$. The comparative analysis of the extreme bounds of COP at optimized $\dot{{\Omega}}$ and $\chi$ figure of merit shows the lower bound of the $\dot{\Omega}$ optimized COP is always higher than that of the $\chi$ optimized COP, while the upper bound of $\dot{\Omega}$ optimized COP is lesser than the $\chi$ optimized COP.
