Screening lubricants for refrigerant compressors: a comparison between a pin and block tester and the high-pressure tribometer.

Author(s) : YOON H. K., POPPE C. H., CUSANO C.

Summary

The tribological characteristics of various lubricant/refrigerant mixtures for refrigerant compressors have been experimentally investigated by means of a unique high-pressure tribometer. In order to identify more effective bench testers for screening lubricants for compressors, a comparison is made between data obtained from a pin and block specimen tester and those obtained from the high-pressure tribometer. The main purpose of this comparison is to see if the controlled environment and the lower loads used with the high-pressure tribometer produce different lubricant rankings than those obtained from the pin and block tests. In general, the results obtained from the high-pressure tribometer do not always correlate to those obtained from the pin and block tester.
