Summary

HFC407C and HFC410A were introduced as alternatives to HCFC22 in air conditioners in compliance with the Montreal Protocol. But HFCs were also regulated by the Kyoto Protocol and natural refrigerants such as hydrocarbons and CO2 are being tested and introduced onto the market. In this article, the authors discuss the compatibility of magnet wires and films of hermetic motors for air conditioners using HFC407C and HFC410A with POE and PVE lubricants and also discuss use of R600a with mineral oil and CO2 with PAG lubricant in comparison with conventional conditions.
