ENHANCED HYDROCARBON LUBRICANTS FOR USE WITH IMMISCIBLE REFRIGERANTS

摘要

In particular, the invention relates to a refrigerant composition for use as refrigerants and lubricants in refrigeration equipment and air conditioning systems. The coolant composition of the present invention comprises a hydrocarbon lubricant, an at least one fluorinated hydrocarbon refrigerant, non-miscible with an ash hydrogen lubricant, wherein each halogen atom fluorine and an effective amount of additive reduce the boundary tension between the hydrocarbon lubricant and the liquid refrigerant to the point where the coefficient of dispersion of the liquid refrigerant on steel is slightly positive, allowing the refrigerant to remove the hydrocarbon lubricant from the steel, wherein the additive is present in an amount of 0.001 to 5 parts by weight of 100 parts by weight of hydrocarbon lubricant. ŕ
