Oil return visualization in refrigerating plants operating on R12 and R134a during retrofitting.

Visualisierung der Ölrückführung in Kälteanlagen mit R12 und R134a bei der Umrüstung.

Type of article: Article

Summary

Use of R134a is an ideal solution when retrofitting existing plants running on R12, since only the oil needs to be changed. The new oils, i.e. alkylbenzene-type partially-soluble oils or water-resistant PVE oils such as ester oils, allow for retrofitting with only one oil to be changed. Moreover, the expense inherent in replacing R12 with R134a will diminish considerably.
