Tandem compressor system and method
View Patent ↗A compressor system including a first compressor and a second compressor. The first and second compressors each include a shell, a compression mechanism disposed within the shell, and a drive member adapted to drive the compression mechanism. A discharge tube assembly interconnects the first compressor and the second compressor, and the discharge tube assembly includes an inlet portion adjacent the first compressor that is inclined relative to another inlet portion adjacent the second compressor. The inlet portion that is inclined is adapted to prevent a backflow of oil through the discharge tube assembly.
1. A compressor system comprising:
a first compressor and a second compressor, said first and second compressors each including a shell, a compression mechanism disposed within said shell, and a drive member adapted to drive said compression mechanism; and
a discharge tube assembly including a first discharge tube and a second discharge tube interconnecting said first compressor and said second compressor, a distal portion of said first discharge tube and a distal portion of said second discharge tube being joined at a common discharge tube, said first discharge tube including a shock loop, and an intermediate portion of said first discharge tube located between said shock loop and said distal portion of said first discharge tube being elevated relative said distal portion of said first discharge tube.
2. The compressor system of claim 1 , wherein said intermediate portion being elevated relative to said distal portion prevents a backflow of oil through said first discharge tube to said shock loop.
3. The compressor system of claim 1 , wherein said intermediate portion is angled relative to said distal portion between 5 degrees and 10 degrees.
4. The compressor of claim 1 , wherein said intermediate portion is angled relative to said distal portion between 1 degree and 90 degrees.
5. The compressor system of claim 1 , wherein said intermediate portion is elevated relative to said distal portion by at least one half a tube diameter.
6. The compressor of claim 1 , wherein a proximate portion of said second discharge tube is elevated relative said distal portion of said second discharge tube.
7. A compressor system comprising:
a first compressor and a second compressor, said first and second compressors each including a shell, a compression mechanism disposed within said shell, a drive member adapted to drive said compression mechanism, a suction inlet fitting, and a discharge fitting; and
a discharge tube assembly extending from said discharge fittings including a first discharge tube and a second discharge tube interconnecting said first compressor and said second compressor, a distal portion of said first discharge tube and a distal portion of said second discharge tube being joined at a common discharge tube, said first discharge tube including a shock loop, and an intermediate portion of said first discharge tube located between said shock loop and said distal portion of said first discharge tube being elevated relative said discharge fitting of said first compressor.
8. The compressor system of claim 7 , wherein said intermediate portion prevents a backflow of oil through said first discharge tube to said shock loop.
9. The compressor system of claim 7 , wherein said intermediate portion is upwardly angled relative said distal portion of said first discharge tube.
10. The compressor system of claim 9 , wherein said intermediate portion is upwardly angled relative said distal portion of said first discharge tube between 5 degrees and 10 degrees.
11. The compressor system of claim 9 , wherein said intermediate portion is upwardly angled relative said distal portion of said first discharge tube between 1 degree and 90 degrees.
12. The compressor system of claim 7 , wherein said intermediate portion is elevated relative to said discharge fitting by at least one half a tube diameter.
13. The compressor of claim 7 , wherein a proximate portion of said second discharge tube is elevated relative said distal portion of said second discharge tube.
