A compressor including a housing defining an interior plenum; a refrigerant received
within the interior plenum and having a resonant wavelength; a motor disposed within
the housing; a compression mechanism disposed within the housing and operably connected
to the motor; and a tuner. The tuner has an open end and a closed end, and defines
a resonating cavity, which is in direct communication with the interior plenum
via the open end. The resonating cavity defines a length extending from open end
to closed end that measures one-fourth of the resonant wavelength of the compressor
assembly or of a noise frequency for which attenuation is desired. The tuner may
be curved or straight and may extend vertically or horizontally. A suction inlet
tube extends through the housing and communicates refrigerant to the interior plenum.
The open end of the tuner indirectly communicates with the suction inlet tube through
the interior plenum.
