Abstract

In recent years, it has been possible to observe a significant expansion of the refrigeration and air conditioning industry. Considering that food refrigeration systems (blast chilling or freezing, cold storage, retail display, etc.) and air conditioners are large energy consumers, this work presents a methodology for evaluating the performance and behaviour of these systems using the thermoeconomic diagnosis concept. The thermoeconomic model used allowed the definition of the condenser and expansion device products, which is not trivial for these components. With that, the thermoeconomic diagnosis was used to evaluate the degradation of refrigeration system components, together with the influence of individual component degradations on efficiency, cooling capacity, operating parameters, and power consumption of the whole system. Through this analysis, a prognosis of system behaviour was obtained, which can be used for maintenance scheduling, as well as for the comprehensive energetic and exergetic analysis of a refrigeration system and each of its components.

用于评估蒸汽压缩制冷系统性能的诊断技术的热经济模型

近年来，制冷和空调行业有了显著的发展。考虑到食品制冷系统（鼓风冷却或冷冻、冷藏、零售展示等）和空调都是耗能大户，本研究提出了一种利用热经济诊断概念评估这些系统性能和行为的方法。所使用的热经济模型允许对冷凝器和膨胀装置产品进行定义，而这对这些组件来说并非易事。因此，热经济诊断用于评估制冷系统组件的退化情况，以及单个组件退化对整个系统的效率、冷却能力、运行参数和功耗的影响。通过这种分析，可以获得系统行为的预报，用于制定维护计划，以及对制冷系统及其每个组件进行全面的能量和能效分析。

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
