Hydrofluorocarbon refrigerants are not soluble in hydrocarbon oil. Retrofittingnrefrigeration equipment with hydrofluorocarbons generally entails the use of expensivenpolyol ester (POE) lubricants. The invention provides hydrofluorocarbon refrigerantncompositions that are soluble in hydrocarbon oil thus allowing for a simpler and lessnexpensive retrofit option to the refrigerant user. |
