In view of a wide range of its speed and a long operation period,attempts have been made to develop high reliability of an inverter controlled compressor designed for a residential heat pump unit. A significant improvement in the long term reliability has been demonstrated by employing a ion-nitrided crankshaft which would help minimizing wear of the bearing. This paper presents the dependency of breaking-in phenomena in hermetic rotary compressors on material combination and discusses the relationship between chemical reaction and wear progressiveness of sliding surface.
