Description
This paper is based on findings resulting from ASHRAE Research Project RP-1249.
Copper plating on steel parts continues to be a problem for all types of compressors operating with HCFC and HFC refrigerant systems. When the copper plating reaches a critical thickness, it causes compressor failures through failed bearings or seized parts. However, the mechanism by which copper plating occurs is not well understood. Consequently, a research program consisting of literature searches, field sample analyses, sealed tube tests and refrigerant/oil circulating tests was performed in order to determine the mechanism of copper plating in refrigeration and air-conditioning systems. The information from the literature search and tests was used to identify compounds and maintenance practices to inhibit specific steps of the proposed copper plating mechanism.
