Influence of residues from aluminium brazing processes on refrigerating systems involving R134a and PAG lubricants.

Author(s) : MEURER C., KÖNIG H., LAUZON D. C.

Summary

Aluminium is recognized as a construction material for refrigeration systems. Each brazing or soldering process produces residues such as soot oxides or flux. The Nocolok flux brazing process is widely used for the production of automotive heat exchangers. The flux that is used for that process remains on the surface of the joined parts after production. A test rig has been erected to examine possible interactions between the flux residues and the refrigeration system. Results are given for R134a and PAG lubricants.
