| Abstract: | Considering comprehensively the effect of heat-resistance, heat leak and internal irreversibility on the performance of Carnot refrigerator, the optimal ecological performance of Carnot refrigerator with Newton heat transfer law is derived by taking an ecological optimization criterion as the objective, which consists of maximizing a function representing the best compromise between the refrigeration rate and entropy production rate of refrigerator. Detailed numerical examples show the effect of different losses on the optimal performance of the irreversible refrigerator. The results can provide some theoretical guidance for the designs of practical refrigerator. |
