摘要： A high side hermetic scroll compressor passes the discharge gas along the interior of the shell and is thereby cooled prior to being subjected to a centrifugal separation to remove the oil before being discharged from the compressor. The separated oil is returned to the sump via a fluid path isolated from the discharge gas.

摘要： A scroll compressor can be provided with different wrap thicknesses to compensate for the different material properties of the orbiting and fixed scroll elements. The concept of different wrap thicknesses also aids in the select-fitting of parts and in the provision of and adjustment of a clearance or spacing between the wrap elements. Additionally, in the manufacture of a scroll compressor, the total wrap thickness of the two wraps is kept constant within narrow tolerances while the individual wrap thicknesses are allowed to vary over a predetermined range. The cutting tools used are sized such that even if they differ in their cutting diameters, the combined cutting diameters, and therefore the total wrap thicknesses, are constant within narrow tolerances. This permits the tools to be used and resharpened until their cutting diameters fall below the minimum acceptable diameter.

摘要： A scroll compressor has a pair of mating scrolls that are disposed on parallel, eccentric axes, and each of these scrolls has a scroll plate and a spiral, involute wrap. The scrolls are driven so that one of them orbits about the axis of the other scroll while maintaining a fixed azimuthal relationship to it. The orbital motion causes a compressible fluid to enter at the periphery of the scrolls, and be carried and compressed by pockets formed between the mating wraps of these scrolls. The compressed gas is discharged out a discharge port at the center of one of the scrolls. The discharge port is bored diagonally into the scroll plate of the one scroll so that it has an elongated elliptical aperture at the center of the scroll plate. The port is machined into the scroll from the wrap side of the scroll. The enlarged size of the port aperture reduces the resistance to fluid flow and hence reduces the back pressure, thereby increasing the compressor efficiency.

摘要： A compressor is powered by a motor which is, in turn, powered by a variable speed drive (VSD). The voltage/frequency relationship of the VSD may be adjusted dynamically to maximize efficiency or permit performance within a compressor performance envelope otherwise unavailable in view of the VSD and motor.

摘要： A portion of the condensed liquid in a condenser is diverted to a generator where it supplies heat to boil off refrigerant from a refrigerant oil mixture and is thereby subcooled. The subcooled liquid is supplied to the motor for cooling. The boiling off of refrigerant in the generator results in an “oil rich” liquid which is supplied to the bearings, etc. for lubrication. One, or more, jet or ejector pumps are preferably used to supply the oil rich liquid to the lubrication distribution system.
