▎ 摘　　要

NOVELTY - Refrigerating machine oil, comprises lubricant additive and base oil. The lubricating additive includes diamond particles and graphene. The particle size of the diamond particles is 0.5-10 nm. The thickness of the graphene is 0.2-10 nm. The graphene includes unmodified graphene or graphene derivatives. The refrigerating machine oil further includes a dispersing agent. The dispersing agent includes succinimide compounds, sodium dodecylbenzenesulfonate, oleic acid, oleic acid ester, cetyltrimethylammonium bromide, silane coupling agent, isopropyl trioleic acid acyloxy titanate or sorbitan fatty acid ester. USE - Used as refrigerating machine oil. ADVANTAGE - The refrigerating machine oil can obviously improve the lubricating performance by adjusting the preparation raw material, when used for refrigerating, compressor can obviously reduce the abrasion of friction pair in the refrigerating compressor and improve the energy efficiency and reliability of the refrigeration compressor. The lubricating additive has excellent self-lubricating performance, large specific surface area and ultra-high elastic modulus and strength. The diamond particles can be in the friction-surface both of them can be used as additive to improve the dispersibility. The size of the diamond particles is nanometer level, the refrigerator oil will generate Brownian motion, so, even without modification, it also can realize good dispersibility, also is through the preparation of the raw material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing refrigerating machine oil; (2) a compressor; (3) a temperature adjusting system; and (4) a refrigeration device.
