摘　　要：氨是一种具有良好热力性质的天然制冷剂，当氨制冷系统得到合理的设计和良好的维护时，也可以有良好的安全性，并使之有望成为一种替代卤代烃制冷剂的理想物质。本文在分析氨的热力性质的基础上，讨论一种简明、高效的氨制冷系统──带满液式蒸发器的直接膨胀供液制冷系统，来替代ＣＦＣｓ和ＨＣＦＣｓ制冷剂的可能性。Ammonia is a refrigerant which occurs in natural condition and has good thermodynamic and trasport performances. By correct design and good maintenace, ammonia refrigeration system may be made in a safe condition and ammoinia can be considered as an ideal substance to replace halocarbon refrigerants. In the article, a simple and high efficient, once-through ammonia refrigeration system with flooded evaporator, is presented to explore the possibility of replacement of CFCs and HCFCs, ammonia.
