REFRIGERATION LUBRICANTS

Compression refrigeration equipment using tetrafluoroethane as a working fluid employs polyoxyalkylene glycols which are at least difunctional with respect to hydroxyl groups and a molecular weight between 300 and 2000. The mixtures of the glycols with the refrigerant will be miscible in the range f...

Beschreibung
Zusammenfassung:	Compression refrigeration equipment using tetrafluoroethane as a working fluid employs polyoxyalkylene glycols which are at least difunctional with respect to hydroxyl groups and a molecular weight between 300 and 2000. The mixtures of the glycols with the refrigerant will be miscible in the range from -40 DEG C. to at least + 20 DEG C.
