Abstract
A system may be operable to circulate a working fluid between first and second heat exchangers. The system may include a suction line, a low-side compressor, a high-side compressor and a discharge line. The low-side and high-side compressors may both be in fluid communication with the suction and discharge lines.
Claims15
A system operable to circulate fluid between first and second heat exchangers and including a suction line, a low-side compressor, a high-side compressor and a discharge line, said low-side and high-side compressors both being in fluid communication with said suction and discharge lines, wherein said suction line is fluidly coupled to a low-side suction inlet and a high-side suction inlet, wherein a discharge outlet of said high-side compressor feeds compressed fluid to said low-side suction inlet,
- wherein said high-side compressor includes a first shell assembly and a first compression mechanism disposed within said first shell assembly, said first shell assembly defines a first discharge-pressure chamber that receives said compressed fluid discharged from said first compression mechanism, and wherein said first compression mechanism is disposed within said first discharge-pressure chamber, and
- wherein said low-side compressor includes a second shell assembly and a second compression mechanism disposed within said second shell assembly, wherein said second shell assembly defines a suction-pressure chamber and a second discharge-pressure chamber, said second compression mechanism fluidly separates said suction-pressure chamber from said second discharge-pressure chamber, said suction-pressure chamber receives fluid from said low-side suction inlet and said second discharge-pressure chamber receives fluid discharged from said second compression mechanism, and wherein said second compression mechanism is disposed within said suction-pressure chamber.
A system operable to circulate fluid between first and second heat exchangers and including a suction line, a low-side compressor, a high-side compressor and a discharge line, said low-side and high-side compressors both being in fluid communication with said suction and discharge lines, wherein said suction line is fluidly coupled to a low-side suction inlet and a high-side suction inlet, wherein said high-side suction inlet receives fluid discharged by said low-side compressor, the system including a bypass conduit directly coupling said suction line with said high-side suction inlet such that fluid is able to flow from said suction line to said high-side suction inlet via said bypass conduit,
- wherein said high-side compressor includes a first shell assembly and a first compression mechanism disposed within said first shell assembly, wherein said first shell assembly defines a first discharge-pressure chamber, and wherein said first compression mechanism is disposed within said first discharge-pressure chamber, and
- wherein said low-side compressor includes a second shell assembly and a second compression mechanism disposed within said second shell assembly, wherein said second shell assembly defining a suction-pressure chamber and a second discharge-pressure chamber, and wherein said second compression mechanism is disposed within said suction-pressure chamber.
