ABSTRACT:
An energy efficient hermetic compressor for compressing hydrofluorocarbon refrigerants. The compressor includes a motor compressor unit with a rotating oil pickup tube to which an oil paddle is attached. The oil paddle rotates in a base lubricant of polyol ester mixed with a siloxane ester foaming agent. The combination of the foaming additive with the oil paddle creates a foam layer that floats in the oil sump to reduce the sound level of the compressor.
