摘要
讨论了三态和五态制冷机模型。基于主方程,推导出2种微观制冷机制冷系数和制冷率的解析表达式,制冷率随制冷系数的变化关系是开型曲线。研究表明:三态以及五态模型制冷机的最大制冷率及对应的制冷系数均随热库温比单调增大;五态模型制冷机中的阶梯宽度对其制冷率和制冷系数的影响是单调递增。
Two kinds of microscopic models of three and five states refrigerators were discussed in this paper. Based on master equation, the analytical expressions for the coefficient of performance and the cooling rate of the microscopic refrigerators were deduced. The curve of the cooling rate versus the coefficient of performance was an opened curve. It was shown that the maximum cooling rate and the corresponding coefficient of performance of the three and five states refrigerator increased monotonously with the temperature ratio of the reservoirs. The influence of the ladder＇s width on the cooling rate and the coefficient of performance of the five states refrigerator was monotonous increase.
