摘要

在本文中，我们进行了一个非等温线性能量转换器在逆模式（冰箱和热泵）运行的能量分析。这是在线性不可逆热力学（LIT）的框架内完成的，从S. Gonzalez等人（S. Gonzalez- hernandez和l. a . a .）提出的逆线性能量转换器（I-LEC）模型开始。Arias-Hernandez，“对线性能量转换器的热电汤姆逊关系的重新审视”，J.非平衡热力学。，第44卷，no。3, pp. 315-332, 2019)。我们将此模型扩展到热泵的情况下，考虑不同的目标函数并执行各自的分析。我们特别关注供暖的性能系数（COP）， ε H。此外，我们提出了其他可能对热泵分析感兴趣的能量函数，与众所周知的冰箱和热机的功能进行类比。最后，我们简要描述了热电现象，主要集中在珀尔帖效应上。简要分析了非等温LEC在热电冷却和加热的情况下获得的结果。

Energetic analysis of a non-isothermal linear energy converter operated in reverse mode (I-LEC): heat pump

In this paper, we perform an energetic analysis of a non-isothermal linear energy converter operated in inverse mode (refrigerator and heat pump). This is done within the framework of linear irreversible thermodynamics (LIT), starting from the model of an inverse linear energy converter (I-LEC) proposed by S. Gonzalez et al. (S. Gonzalez-Hernandez and L.-A. Arias-Hernandez, “Thermoelectric thomson relations revisited for a linear energy converter,” J. Non-Equilibrium Thermodyn., vol. 44, no. 3, pp. 315–332, 2019). We extend this model to the case of heat pumps, considering different objective functions and performing their respective analyses. We particularly focus on the coefficient of performance (COP) of heating, ϵ H . Additionally, we propose other energetic functions that may be of interest in the analysis of heat pumps, drawing analogies with the well-known functions for refrigerators and heat engines. Finally, we present a brief description of thermoelectric phenomena, focusing primarily on the Peltier effect. A brief analysis of the results obtained in the context of thermoelectric cooling and heating is presented for a non-isothermal LEC.

期刊介绍： The Journal of Non-Equilibrium Thermodynamics serves as an international publication organ for new ideas, insights and results on non-equilibrium phenomena in science, engineering and related natural systems. The central aim of the journal is to provide a bridge between science and engineering and to promote scientific exchange on a) newly observed non-equilibrium phenomena, b) analytic or numeric modeling for their interpretation, c) vanguard methods to describe non-equilibrium phenomena. Contributions should – among others – present novel approaches to analyzing, modeling and optimizing processes of engineering relevance such as transport processes of mass, momentum and energy, separation of fluid phases, reproduction of living cells, or energy conversion. The journal is particularly interested in contributions which add to the basic understanding of non-equilibrium phenomena in science and engineering, with systems of interest ranging from the macro- to the nano-level. The Journal of Non-Equilibrium Thermodynamics　has recently expanded its scope to place new emphasis on theoretical and experimental investigations of non-equilibrium phenomena in thermophysical, chemical, biochemical and abstract model systems of engineering relevance. We are therefore pleased to invite submissions which present newly observed non-equilibrium phenomena, analytic or fuzzy models for their interpretation, or new methods for their description.
