摘要

无油线性压缩机有利于扩大制冷系统的潜在应用。针对传统无油压缩机的流动损失问题，提出了一种新型自润滑蒸汽喷射复合轴承线性压缩机。建立了经过验证的线性压缩机数值模型，提出了复合轴承参数的优化框架，以适应双温区制冷系统的工况和制冷要求。优化后的VISLLC与原结构相比，摩擦损失减少25.9%，泄漏损失减少7.3%，系统COP提高16.8%。这些进步为双温区制冷系统的关键部件提供了创新的解决方案，为扩大其应用范围提供了见解。

Design optimization and performance analysis of a self-lubricating linear compressor using vapor injection in a dual-temperature zone refrigerator

Oil-free linear compressor is conducive to expand the potential applications of refrigeration systems. This study introduces a novel self-lubricating linear compressor with vapor injection composite bearings for dual-temperature zone refrigeration system, which can mitigate the flow loss of conventional oil-free compressor. A validated numerical model of the linear compressor is developed, and an optimization framework for the composite bearing parameters is proposed to align with working condition and refrigerating requirements of dual-temperature zone refrigeration systems. The optimized VISLLC reduces frictional losses by 25.9 %, leakage losses by 7.3 % and resulting in 16.8 % improvement of system COP compared to the original structure. These advancements provide innovative solutions for critical components in dual-temperature zone refrigeration systems, offering insights for expanding their application scope.

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.
