摘要
随着R22淡出历史舞台，尤其是近年来多次发生氨制冷系统的安全事故，过渡型氟利昂逐步成为新建大型商业制冷系统的主流，本文在理论上从物理性质，制冷系统后期运行费用等方面对R404A、R507A和氨制冷系统进行对比分析，为以后的制冷系统设计工作提供一些理论参考依据。
In recent years, the ammonia refrigeration system often occurred safety accidents .with R22 out of history, transit freon system gradually becomes main stream in large commercial refrigerations. This paper presents a theoretical analysis of the physical property and the operation cost of refrigeration system between R404A, R507A and ammonia refrigeration system.
