Summary

Compressor manufacturers have been specifying lower viscosity lubricants in order to improve energy efficiency. Polyol ester (POE) lubricants devoid of additives are insufficient in providing the necessary antiwear protection in hydrofluorocarbon refrigerants. As the same time, there are concerns about the potential adverse effects of antiwear additives (deposits in capillary expansion devices). The work presented here describes the formulation of low viscosity POE lubricants that offer enhanced wear protection without sacrificing other performance properties.
