摘要
基于分析原理,研究了回热式空气制冷系统的循环特性。通过建立循环的模型,系统分析了不同工况下,循环各项参数随透平机械压缩比的变化关系。结果表明,存在最佳压缩比使得制冷量和效率达到最大,为压缩空气制冷机的优化设计和工程应用提供了重要的理论基础。
The performance characteristics of a regenerative air refrigerator were studied by means of exergy. An exergy analysis model was established for the air refrigerator to determine the cycle parameters at different pressure ratios of compressors and expanders. It was shown that a maximum value of the refrigeration capacity and the exergy efficiency could be reached with an optimal pressure ratio.
