有限时间热力学用于绘制压缩机驱动的金属氢化物制冷机的冷却功率效率图。两个最重要的参数——反应堆和蓄水池之间的传热阻力和系统的热容量——以详细和现实的方式包含在分析中。与许多其他电力系统不同，金属氢化物反应器内的低导热系数导致的传热阻力是可观的，必须纳入分析。采用一个简单的准稳态模型来研究这种效应及其与系统冷却功率和效率的关系。 金属氢化物能源系统另一个有趣的方面是，增加反应堆外部的翅片会降低效率——冷却功率和性能系数（COP）之间存在权衡。研究了压缩比对系统性能的影响。有限时间热力学分析是研究重要系统参数对功率和效率影响的简单而有力的工具。关键词:1997年，冷却，效率，金属氢化物热泵，压缩机，热力学，热流，热容量，导热系数，冷负荷，反应器，性能系数，性能，计算，制冷引用: 研讨会，ASHRAE Trans。1997年，第103卷，第一部分

Finite-time thermodynamics is used to develop cooling power-efficiency diagrams for a compressor-driven metal hydride refrigerator. The two most important parameters - resistance to heat transfer between the reactors and the reservoirs and the thermal capacities of the system - are included in the analysis in a detailed and realistic way. The resistance to heat transfer due to low thermal conductivity inside the metal hydride reactor is appreciable and must be included in the analysis, unlike many other power systems. A simple quasi-steady-state model is used to investigate this effect and its relation to cooling power and efficiency of the system. Another interesting aspect of the metal hydride energy system is that increased finning outside the reactors reduces the efficiency - a trade-off exists between cooling power and coefficient of performance (COP). The effect of compression ratio on the system performance is also investigated. The finite-time thermodynamic analysis is a simple and powerful tool for investigating the effect of important system parameters on power and efficiency.KEYWORDS: year 1997, Cooling, efficiency, metal hydride heat pumps, compressors, thermodynamics, heat flow, thermal capacity, thermal conductivity, cooling load, reactors, coefficient of performance, performance, calculating, refrigerators
