| Summary: | 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. |
