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 χ and Ω̇ optimization criteria. The lower and upper bounds of the COP for the low dissipation Carnot-like refrigerator under χ and Ω̇ optimization criteria are obtained with power law dissipation level δ=1. The comparative analysis of the extreme bounds of COP at optimized Ω̇ and χ figure of merit shows the lower bound of the Ω̇ optimized COP is always higher than that of the χ optimized COP, while the upper bound of Ω̇ optimized COP is lesser than the χ optimized COP.
