Sealed compressor housing with noise reduction features

摘要

A sealed compressor assembly includes a compressor pump driven by a motor mounted within a sealed housing. The sealed housing comprises a center shell extending between first and second ends and a lower shell attached to the center shell. The lower shell is generally square shaped with mounting feet extending diagonally from each corner. The lower shell includes a predetermined amount of material removed to shift the resonance frequency of the sealed housing outside the operating frequency range of the motor and compressor.
