HALOGENATED HYDROCARBON REFRIGERANT COMPOSITIONS CONTAINING POLYMERIC OIL-RETURN AGENTS

Refrigerant compositions containing polymeric oil-return agents which solubilize or disperse mineral and synthetic oil lubricants with hydrofluorocarbon and hydrofluorocarbon/hydrochlorofluorocarbon-based refrigerants are disclosed. These polymeric oil-return agents, such as copolymers of fluorinate...

More Information
Summary:Refrigerant compositions containing polymeric oil-return agents which solubilize or disperse mineral and synthetic oil lubricants with hydrofluorocarbon and hydrofluorocarbon/hydrochlorofluorocarbon-based refrigerants are disclosed. These polymeric oil-return agents, such as copolymers of fluorinated and non-fluorinated methacrylates, as a small proportion of an overall refrigerant composition, permit efficient return of mineral and synthetic oil lubricants from non-compressor zones back to a compressor zone in a refrigeration system operating with hydrofluorocarbon and hydrofluorocarbon/hydrochlorofluorocarbon-based refrigerants.
