本文论述了遵循热力学第一定律和第二定律的能级平衡(简称第二定律的能级平衡)。它是(火用)分析的发展,与(火用)分析完全一致。当只要了解用能的总情况而不需要各部分(火用)损的详情时,采用能级分析有它简明的优点。进行第二定律的能级平衡时,必须针对固定数量的能量平衡式,由此求得的能级差系数ξ_Ω才是真正衡量系统用能过程合理程度的质量指标。本文通过实例,说明了第二定律能级平衡的正确性。
This paper deals with the energy level equilibrium (the energy balance of the second law) that follows the first law of thermodynamics and the second law. It is the development of (exergy) analysis, exactly the same as exergy analysis. When it comes to understanding the general situation of energy use without the need for details of exergy loss, there are clear advantages to adopting energy level analysis. In order to balance the energy level of the second law, a fixed number of energy balance formulas must be taken. The energy difference coefficient ξ_Ω obtained from this is the true indicator of the reasonableness of the energy consumption process of the system. This article illustrates the correctness of the energy level balance of the second law through examples.
