Abstract

The world is facing the problems of the energy crisis. Thermal analysis and energy conservation of the engineering devices help to improve their performance. This paper conducted an experimental investigation for the performance analysis and exergy assessment of an Inertance Pulse Tube Cryocooler (IPTC) that uses working fluid -helium operated between 80 K cold end side temperature and room temperature.The variation of the different performance parameters like the effect of charge pressure, pulse tube volume, pulse tube length, etc., and its effect on the refrigerating effect isdescribed graphically. Exergy analysis involves the use and concepts of energy andexergy balances, enthalpy, entropy, and exergy calculations at various stages in thesystem. Exergy analysis identifies the zones of key exergy destruction that occurs insidethe system, which afterward can be subjected to its minimization to amend the systemperformance. The actual exergy efficiency value calculated for the overall system is 21.30 %. The decreasing order of exergy efficiency among the different components is acompressor (38.79 %), a hot end heat exchanger (6.19 %), regenerator, pulse tube andinertance tube (6 %), and cold end heat exchanger (2.70 %).

惯性脉冲管制冷机的性能分析与火用评估

世界正面临着能源危机的问题。工程设备的热分析和节能有助于提高其性能。本文对使用工作流体氦气在80K冷端侧温度和室温之间运行的惰性脉冲管低温冷却器（IPTC）的性能分析和火用评估进行了实验研究。用图形描述了充气压力、脉冲管体积、脉冲管长度等不同性能参数的变化及其对制冷效果的影响。火用分析涉及系统各个阶段的能量和能量平衡、焓、熵和火用计算的使用和概念。火用分析确定了系统内部发生的关键火用破坏区域，之后可以对其进行最小化，以修改系统性能。整个系统的实际火用效率计算值为21.30%。不同部件（火用）效率的递减顺序为压缩机（38.79%）、热端换热器（6.19%）、再生器、脉冲管和确定管（6%）和冷端换热机（2.70%）。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
