摘要： A method of operating a refrigeration system uses a plurality of compressors in connected parallel. The method includes returning refrigerant and oil to the compressors, the refrigerant also having oil entrained therein, separating the oil entrained in the refrigerant, and returning more of the oil entrained in the refrigerant to a lead compressor of the plurality of compressors regardless of whether the lead compressor is operating. The method also includes connecting the oil sumps of all of the plurality of compressors such that oil is supplied from the lead compressor to at least one non-lead compressor of the plurality of compressors when the at least one non-lead compressor is operating.

摘要： A scroll compressor that includes a housing and scroll compressor bodies disposed in the housing as well as a method of operation thereof is provided. The housing is separated into different chambers by a separator. One of the scroll bodies is sealed to the separator with a floating seal arrangement including a seal interface between a floating seal of the floating seal arrangement and a hub of a fixed scroll compressor body. A seal retaining ring prevents axial motion of a seal member of the seal interface during start-up operations due to pressure imbalances across the seal member.

摘要： A suction screen member is provided that bridges the inlet port and entrance port between a compressor housing and a suction duct in a scroll compressor. The suction screen member also serves to screen fluid entering the scroll compressor to prevent particulates from entering the scroll compressor. The suction screen member may be formed from only two components, including a sheet metal body that has a folded over section to provide a mounting segment that mounts into the inlet fitting for the outer housing and a tubular extension. Crimping of the folded over segment can secure the screen thereto. Other embodiments may have employ welding for screen attachment.

摘要： A scroll compressor and assembly includes a suction duct to direct refrigerant from the housing inlet to a location upstream of a motor. Additionally, the suction duct includes drain ports that act to drain oil received in the suction duct into the oil sump. This can be used for filling and charging the oil sump with oil initially by using the common refrigerant inlet port through the housing and also acts to collect coalesced oil from oil mist generated by operation of the scroll compressor in a refrigeration system and likewise drain the lubricant oil into the lubricant sump.
