STABILITY REQUIREMENTS OF LUBRICANTS FOR ALTERNATIVE REFRIGERANTS.

Author(s) : SPAUSCHUS H. O.

Summary

HISTORICALLY, THE THERMAL LIMITS OF LUBRICANTS FOR CFC REFRIGERANTS HAVE BEEN DETERMINED BY THE TEMPERATURES AT WHICH CHEMICAL REACTIONSOCCURRED BETWEEN THE REFRIGERANT AND LUBRICATING OIL. WITH THE INTRODUCTION OF ALTERNATIVE REFRIGERANTS, CONVENTIONAL REFRIGERANT/LUBRICATING OIL CHEMISTRY NO LONGER APPLIES. THE PAPER PRESENTS A REVIEW OF REFRIGERANT/LUBRICATING OIL CHEMISTRY FOR CFCS, HCFCS AND HFCS. NEW METHODS FOR DETERMINING THE STABILITY REQUIREMENTS OF SYNTHETIC LUBRICANTS WILL BE DISCUSSED WITH SOME EXAMPLES OF RESULTS FOR POLYALKYLENE GLYCOLS AND POLYOLESTERS.
