Abstract :
A range of hermetic compressor motor insulation materials is examined for compatibility with the hydrofluorocarbon (HFC) refrigerants HFC32, HFC134a and HFC125 and with a neopentylpolyol ester refrigeration lubricant. The results indicate that when compared to R22 and R22-mineral oil standards, the HFC refrigerants and the refrigerant-lubricant mixtures show comparable, or in many cases less aggressive, behavior towards the majority of the motor insulation materials studied
