Fluorocarbon, oxygenated and non-oxygenated lubricant, and compatibilizer composition, and method for replacing refrigeration composition in a refrigeration system

摘要

The present invention relates to refrigerant compositions comprising a fluorocarbon, an oxygenated lubricant, a non-oxygenated lubricant, and a compatibilizer. The present invention further relates to methods for replacing a chlorofluorocarbon and/or hydrochlorofluorocarbon and a non-oxygenated lubricant composition with a fluorocarbon and an oxygenated lubricant composition in a compression refrigeration system without flushing residual non-oxygenated lubricant from the system.
