| 摘 要： | 制冷剂在制冷系统中的合理分布及其迁移特性是制冷系统优化设计和优化控制的重要问题,本文概述了国内外对制冷系统中制冷剂分布及迁移特性的研究现状,通过对制冷系统稳态运行,启停机动态过程研究成果的分析,指出明确压缩机长时间停止工作后制冷剂在系统中分布特性以及随室内,外温度变化的迁移特性不权有助于提高动仿真的精度,而且对系统的故障诊断,优化控制策略,改病况系统性均有指导意义.

| Abstract: | It is commonly recognized that distribution and migration characteristics of refrigerant properly in refrigeration system is important for refrigeration system optimization. This paper surveys researches of refrigerant distribution and migration characteristics of refrigeration system, analyzes conclusions of researches in steady and dynamic state. It also points out refrigerant distribution and migration characteristics of refrigerant after shutdown of compressor for a long time is crucial to improve precision of dynamic simulation, direct diagnosis and improve performance. |
