Research on Thermodynamic Model of Four-reservoirs Refrigeration Based on Concept of Relative Irreversibility

摘要:

基于热力学原理提出了相对不可逆度的概念用于描述系统内部的不可逆因素，在此基础上建立了四热源吸收式制冷系统内不可逆有限时间热力学模型，进行了具体的数值算例分析，并与传统的四热源吸收式制冷有限时间热力学模型进行了比较.

Abstract:

Based on the principle of thermodynamics,a new concept of the relative irreversibility is put forward to describe the internal irreversibility.An irreversible thermodynamic model of four reservoirs absorption refrigeration based on this concept is derived,and numerical examples are given.The differences of the new model and the traditional model are discussed.
