| 摘要: |
| 为了探讨制冷剂R290与冷冻机油的相溶性，建立了一套油与制冷剂相溶性测试实验台，考察了制冷剂R290与矿物油、POE油、PAG油、AB油五种类型冷冻机油的相溶性。结果表明，制冷剂R290在五种冷冻机油中的溶解质量百分含量顺序为：AB油＞环烷基矿物油＞烷基矿物油＞POE油＞PAG油；R290在烷基矿物油、POE油、PAG油中的溶解质量百分含量均随温度的增大而降低，随压力的增大而升高；在环烷基矿物油、POE油、PAG油中的溶解质量百分含量均随运动粘度增大而降低；与运动粘度相比，温度和压力对R290在冷冻机油中的溶解质量百分含量影响较大。 |

| Abstract: |
| In order to explore the miscibility of lubricants with the natural refrigerant R290, an experimental device was established. The miscibility of naphthenic oil, paraffinic oil, polyol ester, polyalkylene glycol and alkylbenzene with the natural refrigerant R290 was investigated. The results showed that the dissolution of the highest mass percentages of the refrigerant R290 was in the AB oil, followed by naphthenic oil and paraffinic oil, and finally polyol ester and polyalkylene glycol. The dissolution of the mass percentage of R290 in paraffinic oil, polyol ester and polyalkylene glycol decreased with increasing temperature, and increased with increasing pressure. Moreover, the dissolution of the mass percentage of R290 in a naphthenic oil, polyol ester and polyalkylene glycol decreased with increasing viscosity. Compared with viscosity, temperature and pressure presented greater influence on the dissolution percentage of R290 in lubricants. |
