提出探讨了一种有希望替代 ＨＣＦＣ２２的三元混合工质─ＨＦＣ３２／ＨＦＣ１４３ａ／ＨＦＣ１３４ａ。 理论制冷循环和水合性能分析表明：在推荐组成下该物系的热力学性质与ＨＣＦＣ２２基本相当，理 论制冷循环ＣＯＰ和容积制冷量均略优于ＨＣＦＣ２２，在空调循环蒸发工况下能够形成气体水合物。
Proposed to explore a promising alternative to HCFC22 ternary mixed refrigerant ─ HFC32 / HFC143a / HFC134a. The theoretical refrigeration cycle and hydration performance analysis show that the thermodynamic properties of the system are basically the same as that of HCFC22 under the recommended composition, and the theoretical refrigeration cycle COP and the volumetric refrigeration capacity are slightly better than HCFC22, which can form gas hydrate .
