Lubricant Options for Screw Compressors Using Alternative Refrigerants

Abstract Environmental concerns have created need to find replacements for HFC and in some cases HCFC refrigerants used screw compressor applications. Like most refrigerant changes it becomes necessary assess the best lubricant option order maintain system reliability performance. Regardless of magnitude allows opportunity appraise alternative chemistries that are different from what was past. This paper will investigate various being evaluated Choices be presented not only seen past but also offers potential advance application ranges while using a single with operational designs. As always needed when evaluating lubricants refrigerants, information on interaction properties along stability material compatibility presented. Comparisons made legacy data operation improvements available combinations lubricants.
