摘要： A refrigeration system with two or more compressors configured to compress a flow of refrigerant with oil entrained therein. A suction flow piping arrangement is configured to supply a flow of refrigerant and oil to the two or more compressors. The suction flow piping arrangement has a suction header configured to carry the flow of refrigerant and oil, and a primary compressor supply conduit connected to the suction header. The primary compressor supply conduit supplies refrigerant and oil to a first compressor of the two or more compressors. A secondary compressor supply conduit branches off from the suction header. The secondary compressor supply conduit supplies refrigerant to a second compressor of the two or more compressors. The primary compressor supply conduit is configured to supply more oil to the first compressor than the secondary compressor supply conduit supplies to the second compressor.

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： The seat of a suction valve of a reciprocating compressor is modified to limit the area in which an annular oil film can be established between the valve and the valve seat. The seat is configured to limit the oil film from 3% to 33% of the total inlet port opening. In a modified embodiment gas at discharge pressure exerts an opening bias to the suction valve at the end of the discharge stroke.

摘要： The seat of a suction valve of a reciprocating compressor is modified to limit the radial extent and thereby the area in which an annular oil film can be established between the valve and the valve seat. The preferred radial extent of the seating surface is 0.014 to 0.018 inches and the preferred ratio of the area of the suction valve seat to the passage therethrough is in the range of 13% to 25%.

摘要： In its unstressed state, a suction valve is spaced from its valve seat such that the suction valve must be deformed against its inherent spring force in order to achieve seating. The spring force due to deformation provides an opening bias to the suction valve such that it opens earlier in the suction stroke and offsets the effects of adhesion due to the presence of oil between the seating surface and the valve.

摘要： A method of operating a multiple-compressor refrigeration system is provided. This method includes the steps of supplying, via a common supply line, refrigerant gas and oil to a plurality of compressors coupled in series, and attaching an oil flow conduit between adjacent compressors of the plurality of compressors. The oil flow conduit is configured to move oil from a compressor with a relatively higher pressure to a compressor with a relatively lower pressure. The method further includes controlling the pressure for each of the plurality of compressors by regulating a speed at which each of the plurality of compressors operates in order to maintain a pressure differential between the adjacent compressors to facilitate the flow of oil from the compressor with the relatively higher pressure to the compressor with the relatively lower pressure.
