本文筛选了可能作为替代制冷剂的氟化醚类(HFEs)纯物质和混合物，然后对这些工质的制冷循环性能进行了热力学分析。分析结果表明：在醚类纯质及混合物中c-HFE 216、HFE143a、c-E2-216、c-HFE216/HFE143a和c-HFE216/c-E2-216适合替代CFC12和 HFC134a；HFE125适合替代CFC115；HFE134、HFE245cb和HFE143/HFE31-10适合替代CFC114；HFE338mf、HFE245fa、HFE143、HFE263fb、HFE236ea/HFE245fa和HFE236ea/HFE143有望成为CFC11的替代物。
In this paper, some pure and mixture substancesof fluorinated ethers (HFEs) were put forward tobe able to replace chlorofluorocarbon (CFC) refrigerants, and theperformances of refrigeration cycle ofthose new substances were theoretical analyzed. The resultsshow that c-HFE 216、HFE143a、c-E2-216 andthe mixture c-HFE216/HFE143a、c-HFE216/c-E2-216 are suitableto replace CFC12 and HFC134a; HFE125is suitable to replace CFC115; HFE134、HFE245cb andHFE143/HFE31-10 are suitable to replace CFC114;HFE338mf、HFE245fa、HFE143、HFE263fb and HFE236ea/HFE245fa、HFE236ea/HFE143 are suitable to replace CFC11.
