Qα△(T^n)时不可逆卡诺致冷循环工况对其性能的影响

THE INFLUENCE OF THE WORKING CONDITION OF IRREVERSIBLE CARNOT REFRIGERATION CYCLE ON ITS PERFORMANCE FOR THE CASE Qa△(T^n)

本文在定义致冷循环内不可逆性的基础上,研究了Qα△(T^n)时不可逆卡诺致冷循环工况对其性能的影响,得到了优于已报道的致冷系数与致冷率间的优化关系,讨论表明,这一关系是线性、非线性传热与内可逆及内不可逆多种情况下卡诺致冷循环普遍满足的基本优化公式.

This paper,on the basis of defining the endo-irreversibility of refrigeration cycle,disusses the influence of the working con-dition of Carnot refrigeration cycle on its performance for the case Qα△(T^n).The favourable relation between the coefficicent ofrefrigeration and the rate ot refrigeration obtained from the study is much better than that documented reference in 1991.The dis-cussion reveals that this relation proved is the universal satisfying basic favourable formulation of Carnot refrigeration cycle underthe condition of liear and non-linear heat transfer,endo-reversible and endo-irreversible and so forth.
