负温热泵及功机的最佳性能系数

Optimal Coefficient of Performance of Ifeat Pump operating at Negafive Temperature and Energy-lfeat Transformation Machine

本文从有限时间热力学出发,讨论了负温热泵及功机的最优化问题,导出了负温热泵、功机的最佳性能系数与供热率、功热转换率之间的关系式。

Based on finite-time thermodynamics, this Paper eleals with the optimal Performance Problem of heat Pump operating at negative temperature andenergyhe-at transformation machine.lt has worked out the relations between maiimumeffi-ciency of heat Pump operating at negatire temperature and rate of heat-Producing and between maximum efficiency of energy-heat transformation ma-chine and energy-heat rafe of transformation.
