Abstract:
The present invention relates to a method for increasing the solubility of oils in refrigerant compositions within a system using a refrigerant compressed with a mechanical device by adding polyolester directly to the refrigerant followed by charging a mixture of the polyolester and refrigerant into the system (air conditioner, refrigerator, etc.). The present invention also relates to a method of optimizing mineral oil return in a system using a refrigerant compressed with a mechanical device and a method of cleansing heat exchange tubes of a system using a refrigerant compressed with a mechanical device by adding polyolesters directly to a refrigerant composition followed by charging a mixture of the polyolester and refrigerant into the system.
