不可逆卡诺制冷机的最小附加功率

Minimum Additional Power of an Irreversible Carnot Refrigerator

导出存在热阻、热漏和内不可逆性的不可逆卡诺制冷机在给定制冷率下的最小附加功率，并由此导得一些新性能界限．所得结论可为制冷机的优化设计和最佳工况选择提供些新理论依据．

The minimum additional power at a given refrigeration rate of an irreversible Carnot refrigerator with thermal resistance,heat leak and internal irreversibilities is derived in this paper.Some new performance bounds are obtained from it.The conclusions obtained here may provide some new theoretical guidance for the optimal design and the selection of optimal operating conditions of a real refrigerator.
