Zusammenfassung: | A fluid composition of suitable miscibility and solubility in ammonia, chlorofluorocarbon, hydrochlorofluorocarbon, and hydrofluorocarbon refrigerants includes and a refrigerant selected from the group consisting essentially of ammonia, chlorofluorocarbons, hydrochlorofluorocarbons, and hydrofluorocarbon refrigerants and a lubricant composition made with an organic oxide and an alcohol and comprises a polyalkylene glycol of the formula:Z-((CH2-CH(R1)-O)n-(CH2-CH(R1)-O-)m)p-Hwherein Z is a residue of a compound having 1-8 active hydrogens and a minimum number of carbon atoms of six (6) carbons where Z is an aryl group and a minimum number of carbon atoms of ten (10) where Z is an alkyl group, R1 is hydrogen, methyl, ethyl, or a mixture thereof, N is 0 or a positive number, M is a positive number, and P is an integer having a value equal to the number of active hydrogen of Z. |
