“顾氏循环”论析

A Thermodynamic Analysis of the "G Cycle"

本文论述了可逆循环与不可逆循环以及恒温热源与变温热源的不同热力学概念,从而论证了“顾氏循环”的热效率比卡诺循环为高,或者“顾氏循环”的制冷系数比逆卡诺循环为高的结论是不能成立的。同时分析了“顾氏循环”与劳伦兹循环的区别,得出了“顾氏循环”就是100年前的劳伦兹循环,并无丝毫突破。

This paper explains the thermodynamic concepts of 'reversible cycle and irreversible cycle' , 'isothermal heat resource' and 'heat resource of changeable temperature' . On this basis the Carnot cycle and 'G cycle' are analysed, and the conclusion that the latter is superior than the former in thermodynamics is disproved. Furthermore, a comparison is made between the 'G cycle' and the Lonrenz cycle, through which it can be concluded that the 'G cycle' is nothing new, but a copy of the Lonrenz cycle.
