| 摘要: |
| 通过分析在使有用HFC制冷剂的各种压缩机和系统试验中的已用润滑油，调查PVE润滑油的劣化度。结果未观察到PVE本身的劣化度，确定了PVE的长期可靠性。随后又进行了水和空气的蒸压试验，以确定PVE对于矿物油和聚烯酯的可靠性界限值。这些研究表明，HFC制冷剂用PVE润滑油对空气或水污染有充分耐受力，可确保其长期可靠性。 |

| Abstract: |
| Deterioration degree of PVE Lubricants was investigared by analyzing used oils after various compressor and system tests with HFC refrigerants. As a result,deterioration of PVE itself was not observed and long term reliability was confirmed. Furthermore,autoclave tests with water and air were performed to determine the reliability limit of PVE in comparison with mineral oil and polyolester. Through these studies, it was conrirmed that PVE with HFC refrigerant has enough tolerance to air or watre contamination to secure long term reliability. |
