Re: ihc-digest V5 #124 Lubrication in A/C compressors

[Steve Stegmann <stegmann@domain.elided>]

Dan,

The compressors require lubrication.  The all have oil in the crankcase 
just like an engine or regular air compressor.  Some of the oil travels 
around the system with the freon.  Not required just happens and doesn't 
hurt anything.

The new and old refrigerants (R12 and R134a) have incompatible oils.  But 
the oil travels with the freon on either system.
