Abstract:
An energy efficient hermetic compressor for compressing hydrofluorocarbon refrigerants. The compressor includes a motor compressor unit (20) with a rotating oil pickup tube (30) to which an oil paddle (76) 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 (74) to reduce the sound level of the compressor.
