A shell for a hermetic compressor unit, the shell having a top section or dome, and a bottom section, the dome having a unique shape which gives enhanced capacity for absorbing and attenuating structural and fluid transmitted wave energies emanating from the unit at wave frequencies of between 1,000 Hz and 2,000 Hz, while reducing total operating noise of the unit, the dome being formed of sheet metal and having a generally inverted cup-shaped configuration with generally cylindrical sidewalls and a top wall having a central portion surrounded by a peripheral portion, wherein the sidewall taken in a generally axial direction is substantially straight, wherein the central portion of the top constitutes from about 40 to about 90% of the total area of the top and has a generally hemispherical configuration on a mean radius of from about 6. 5 to about 10. 0 inches as measured from an origin point O. sub.

A muffler system for a compressor includes an expansion chamber muffler for attenuating sound pressure pulses and an acoustic muffler for filtering high-frequency pressure pulsations. The acoustic muffler is connected inline along the discharge side of the compressor between the discharge port of the cylinder head and a discharge tube in fluid communication with the outlet port of the compressor housing. A conduit is in fluid communication between the outlet port of the compressor housing and the condenser to supply the flow of refrigerant therebetween. Interposed adjacent the compressor housing, but exterior to the compressor housing is an expansion chamber muffler in fluid communication with the conduit for further attenuating pressure pulses generated by operation of the compressor.

A hermetic compressor unit housing comprised of a shell having a top section and a bottom section which receives the top section, the shell being formed of sheet metal and having generally cylindrical sidewalls wherein the sidewall taken in a generally axial direction is substantially straight, each shell section having an opening, a substantially cylindrical portion, and a closed end portion, the opening having a substantially circular horizontal cross-sectional geometry defined by a major axis and a minor axis, the horizontal cross-sectional geometry including substantially liner opposing sidewall portions preferably disposed adjacent to the intersection of the horizontal sectional geometry with the minor axis, and methods of aligning the shell sections for installation of fixtures and mating of the shell sections.

A system and method for determining a fault condition in a compressor is provided. The current of a motor drive powering the compressor and the outdoor ambient temperature are measured and used to determine if a fault condition or a potential fault condition is present in the compressor. If a fault condition is determined to be present, the compressor can be shutdown to avoid damage to the compressor. If a potential fault condition is determined, remedial action can be taken to attempt to prevent the fault condition from occurring and shutting down the compressor.

A single piece offset mounting foot is positioned between the compressor and the floor of a cabinet for the compressor. The offset mounting foot has a main body having a geometric shape with a top and bottom surface connected by sidewalls that form a perimeter. A depression in the top surface receives a compressor and is offset in the direction of one of the sidewalls. A plurality of substantially equally spaced legs extend outward from the main body. The thickness of the offset mounting foot may be substantially uniform through the main body. The profile of the top surface in the main body is substantially concave forming a bowl-like surface that transitions smoothly from a minimum within the concave surface or concavity to a maximum in the direction toward the periphery and in the direction away from the center of the concavity. The bottom surface of the main body is configured or profiled to contact the floor or base of the cabinet into which the compressor is to be installed.

A system and method for starting a compressor is provided. An amount of liquid refrigerant that is located in an oil sump of the compressor is determined. Using the determined amount of liquid refrigerant, a starting algorithm for the compressor is selected. The selected starting algorithm is configured to remove the determined amount of liquid refrigerant from the oil sump before the compressor reaches a preselected operating speed. The selected starting algorithm is then executed to start the compressor.

A muffler system for a compressor includes an expansion chamber muffler for reducing pressure pulses at the compressor's fundamental pulsation frequency and a side-branch muffler for filtering high-frequency pressure pulses. The expansion muffler is positioned along the compressor discharge stream at a location that maximizes pulsation reduction at the compressor's fundamental pulsation frequency. The side-branch muffler is tuned to the frequency at which the pulsation reduction for the expansion muffler is at a minimum.
